Given m
11
n, find the value of x and y.
m
(5x+9)
(y+20)
n
(4x+17)
Answer: x=8 and y=29
Step-by-step explanation:
Since the lines M and N are parallel to each other, the corners that are across from each other are equal. This is true for the corners formed by the lines on the top and bottom.
So, all of the given equations can be set equal to each other. ie: (5x+9)=(4x+17)=(y+20).
Now, since the first two expressions both have x as their only variable, set those equal to each other and do not include the y expression.
ie: (5x+9)=(4x+17)
Now solve for x by subtracting 4x from each side.
ie: x+9=17
Now subtract 9 from each side
ie: x=8
Now you have your X value
Use your X value to solve one of the x variable equations.
ie: 5(8)+9
This equals 49.
Use this answer to substitute it in the equation where we set them all equal.
ie: 49=y+20
Now solve for y using this equation
ie: y=29

At a chili festival over the past few years , restaurant a won 56 out of 98 contest. Restaurant b won 84 out of 147 contests. Which restaurant has the better record? what decimal represents the wins for restaurant a ? what decimal represents the wins for restaurant b?
At the chili festival both restaurant (a) and (b) have the same record of winnings as they have equivalent fractions: 4/7
Information about the problem:
Winnings restaurant a = 56Contest restaurant a = 98Winnings restaurant b = 84Contest restaurant b = 147Which has the better record=?what decimal represents the wins for restaurant a =?what decimal represents the wins for restaurant b =?Calculating which restaurant has the better record, we get:
Rate (a) = Winnings restaurant a / Contest restaurant a
Rate (a) = 56/98
Simplifying, we get:
Rate (a) = 4/7
Rate (a) = 0.5714285
Rate (b) = Winnings restaurant b / Contest restaurant b
Rate (b) = 84/147
Simplifying, we get:
Rate (b) = 4/7
Rate (b) = 0.5714285
That means 56/98 and 84/147 are equivalent fractions.
What is a fraction?Is a number that expresses the portion of some number over a total. The number that expresses the portion is known as the numerator and the number that expresses the total is known as the denominator.

Oliver is starting a running plan to train for a race. In the first week of his running plan, Oliver will run 14 miles. The plan calls for Oliver to increase his weekly milage by 3.5 miles every week. If Oliver sticks to the plan, how many miles would he be expected to run during his 10th week of the training plan?
Answer:
49 miles
Step-by-step explanation:
Let x be equal to the no. of weeks and y be equal to the total amount of miles ran.
Then the equation will be, y = 3.5x + 14
Now to find the amount of miles Oliver ran during the 10th week substitute 10 for x.
So, y = 3.5(10) + 14
y = 35+14
y=49

A major fishing company does its fishing in a local lake. The first year of the company's operations it managed to catch 95,000 fish. Due to population decreases, the number of fish the company was able to catch decreased by 4% each year. How many total fish did the company catch over the first 10 years, to the nearest whole number?
Answer/step-by-step explanation:
We know that during their first year, the company caught 95,000 fish, and the amount of fish caught decreased 4% each year. First, let's calculate 4% of 95,000, by doing the equation: 95,000 x 0.04 = 3,800
So, each year, the company catches 3,800 less fish.
In order to find out how many fish the company caught in ten years, we need to multiply 3,800 x 10 and then subtract it from 95,000. Then we need to multiply that number by 10.
3,800 x 10 = 38,000
95,000 - 38,000 = 57,000 x 10 = 570,000.
Therefore, the company caught a total of 57,000 fish in the first ten years.

Your savings account pays 1.75% interest per year. You make a $500 deposit. How much interest does the account earn in the first month.
The interest the account earn in the first month is = $0.73
The amount deposited( = $500
The payment rate per year = 1.75%
The payment time = per year(12 months)
Therefore simple interest in first month=

The graph represents f(x) = x +3
On a coordinate plane, a step graph has horizontal segments that are each 1 unit long. The left end of each segment is an open circle. The right end of each segment is a closed circle. The left-most segment goes from (negative 5, negative 1) to (negative 4, negative 1). Each segment is 1 unit higher and 1 unit farther to the right than the previous segment. The right-most segment goes from (1, 5) to (2, 5).

Answer:

Step-by-step explanation:
edge 2020 :) have a nice day
The required value of f(-2.2) is 1 for the given function f(x)=x+3. The correct answer is an option (C).
The given function is f(x)=x+3.
To find f(-2.2) on the given graph of f(x) = x + 3, we need to locate the corresponding point on the step graph.
From the information provided, we know that the left-most segment starts at (-5, -1) and ends at (-4, -1), and each segment is 1 unit higher and 1 unit farther to the right than the previous segment.
To determine the value of f (-2.2), we need to find the segment that includes the x-coordinate of -2.2.
Since the x-coordinate -2.2 falls between -4 and -3 (1 unit to the right of the left-most segment), the corresponding y-coordinate is 2 units higher than the starting y-coordinate of -1.
So, f(-2.2) = −1 + 2
f(-2.2) = 1.
Thus, the required value of f(-2.2) is 1.

Using the given table of an exponential function, determine the growth/decay factor as well as the rate of increase/decrease. Type your answers in as numbers. Example: Growth Factor: 3.5, Rate of Increase: 2.5. (Do not input your rate of increase as a percent.)
f(x)=75(1-.3)^x
Answer:
0.7 is the growth factor
0.3 is the growth rate
Step-by-step explanation:
Here, we want to get the growth rate and the growth factor
Let us consider the general form of an exponential equation
That will be;
y = a(1 + r)^n
The growth rate is r
while the growth factor is the term (1 + r)
From the given exponential function;
-0.3 is the rate of increase
Growth rate is 1-0.3 = 0.7
Linda headed east at 20 miles per hour on her bicycle at 9 a.m. Three hours later Shanna headed west from the
same place, walking at 6 miles per hour. What time was it when they were 164 miles apart?
Step-by-step explanation:
Let t = time (in hrs) Linda rode her bike
Then (t-3) = Shana's time walking
:
Write a distance equation: dist = speed * time
:
Linda's dist + Shana's dist = 164
20t + 6(t-3) = 164
20t + 6t - 18 = 164
26t = 164 + 18
26t = 182
t = 182/26
t = 7 hrs, Linda is on the road
:
Time: 9 AM + 7 hrs = 4 PM, they will be 162 miles apart
:
Check using Linda's and Shana's distances:
20(7) + 6(7-3) =
140 + 24 = 164 mi
through (-4,3) , perpendicular to m=-2/3
Answer:
The equation of the line:
[tex]y=\frac{3}{2}x+9[/tex]
Step-by-step explanation:
Given
The point (-4, 3)m = -2/3We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:
slope = m = -2/3
perpendicular to m = -1/m
[tex]=-\frac{1}{\left(\frac{-2}{3}\right)}=\frac{3}{2}[/tex]
Using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
substituting the values m = 3/2 and the point (-4, 3)
[tex]y-3=\frac{3}{2}\left(x-\left(-4\right)\right)[/tex]
[tex]y-3=\frac{3}{2}\left(x+4\right)[/tex]
Add 3 to both sides
[tex]y-3+3=\frac{3}{2}\left(x+4\right)+3[/tex]
[tex]y=\frac{3}{2}x+9[/tex]
Thus, the equation of the line:
[tex]y=\frac{3}{2}x+9[/tex]
Protozoa are single-celled organisms.
Paramecium aurelia is one type of protozoan. The
number of Paramecium aurelia protozoa doubles
every 1.25 days. There was one protozoan on a slide
5 days ago. How many protozoa are on the slide now?
The number of protozoa makes a series where every next term is double its previous term so on the slide now the number of protozoa is 16.
What is a series?A series follows some pattern for example if you take data set of natural numbers then there will be a sequence of that data and something will be due to that we can form that series.
Number of protozoa 5 days ago = 1
Since protozoa double every 1.25 days.
Number of times protozoa doubles in 5 days ⇒
5 / 1.25 = 4 times.
So,
1 →2 → 4 → 8 → 16
Hence "The number of protozoa on the slide now is 16".

solve for x please i need help
Answer:
x = 4
Step-by-step explanation:
By exterior angle theorem:
(9x + 1)° + (11x - 2)° = (19x + 3)°
(9x + 1 + 11x - 2)° = (19x + 3)°
(20x - 1)° = (19x + 3)°
20x - 1 = 19x + 3
20x - 19x = 3 +1
x = 4

(b) A number has digits that are all 9 and is divisible by 13. Show that
it is also divisible by 1001.
Part (a)
Note 999999=1000000-1. By Fermat's little theorem, since 100000=10⁶,
[tex]10^{6} \equiv 1 \pmod{7} \\ \\ \therefore 10^{6}-1 \equiv 0 \pmod{7}[/tex]
Part (b)
Note that
[tex]10^{12n}-1=(10^n)^{12}-1 \equiv 0 \pmod{13}[/tex]
Since
[tex]1 = 1001 - 1000[/tex]
and
[tex]-1 \equiv 1000 \pmod{1001}[/tex]
10³ is its own inverse modulo 1001, meaning that:
[tex]10^3 x \equiv 1 \pmod{1001} \implies x=10^3 \\ \implies 10^{12n}=(10^3 \cdot 10^3)^{2n} \equiv 1 \pmod{1001} \\ \\ \implies 10^{12n}-1 \equiv 0 \pmod{1001}[/tex]
