X-4y=15 and 8x-5y=42
Answer:
y=-2 8/9
x=31 1/2
Step-by-step explanation:
x-4y=15 --> x=4y+15
8x-5y=42
8(4y+15)-5y = 42
32y +120 - 5y = 42
27y = -78
y=-2 8/9
x=31 1/2

Answer:
19) ( [tex]\frac{-2}{5}[/tex])^2 = [tex]\frac{4}{25}[/tex]
20) -[tex]9^{2}[/tex] = -81
21) [tex]2^{4}[/tex] = 16
Step-by-step explanation:
The only wrong ones are
19) ( [tex]\frac{-2}{5}[/tex])^2 = [tex]\frac{4}{25}[/tex]
20) -[tex]9^{2}[/tex] = -81 ... negative is not inside a parenthesis that's why it is still negative
21) you can add another way is [tex]2^{4}[/tex] = 16
Everything else looks good. Great job!
is this a function or not a function explain why or why not
Vanessa bought a 30 pound bag of rice she cooked 7.5 pounds of the rice she stores the rest of the rice in 4.5 pound portions what is the maximum number of portions she stored
Given :
Vanessa bought a 30 pound bag of rice she cooked 7.5 pounds of the rice she stores the rest of the rice in 4.5 pound portions.
To Find :
The maximum number of portions she stored.
Solution :
Let, number of portions she stored is n.
Amount of rice left, A = 30 - 7.5 = 22.5 pounds.
Now, number of portions of 4.5 pounds she stored :
[tex]n = \dfrac{22.5}{4.5}\\\\n = 5[/tex]
Therefore, maximum number of portions she stored is 5.
Hence, this is the required solution.

6. Write the
equation
(0,5) and (5,1)
Answer:
There is no equation that you can write for that because the slope is undefined becasue 0 is in the denominator
Step-by-step explanation:
9514 1404 393
Answer:
4x +5y = 25
Step-by-step explanation:
One way to write the equation is ...
(y2 -y1)x -(x2 -x1)y = (y2 -y1)(x1) -(x2 -x1)(y1)
(1 -5)x -(5 -0)y = (1 -5)0 -(5 -0)5
-4x -5y = -25 . . . . . has a leading minus sign, so we want to multiply by -1
4x +5y = 25 . . . . standard form equation of the line
__
Another way to write the equation is ...
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (1 -5)/(5 -0)(x -0) +5
y = -4/5x +5 . . . . slope-intercept form of the equation of the line

Multiplying and Dividing by Powers of 10 When multiplying a number by 10, move the decimal to the right. When multiplying a number by 0.1, move the decimal to the left. Why?
Answer:
Because we actually divide by 10 when a number is multiplied by 0.1.
Step-by-step explanation:
Let [tex]a[/tex] be a number.
When we multiply a number by 10:
[tex]a \times 10 = 10 a[/tex] (One '0' is increased in the number)
For example:
[tex]23 \times 10 = 230[/tex]
Considering a decimal number:
[tex]2.3 \times 10 = 23[/tex]
Multiplying a number with 0.1 (which is actually [tex]\frac{1}{10}[/tex]) means dividing the number by 10.
[tex]23\times 0.1 =23\times \frac{1}{10}=2.3[/tex]
Considering a decimal number:
[tex]2.3 \times 0.1 = 2.3 \times \frac{1}{10} = 0.23[/tex]
Therefore, When multiplying a number by 0.1, move the decimal to the left.
Answer:
Sample Response: You move the decimal to the right when multiplying a number by 10 because you are making the number bigger. You move the decimal to the left when multiplying a number by 0.1 because you are making the number smaller.

Emily is preparing cookies for her friends she is at the market where she sees a 14 ounce bag of chocolate chips for 3.50 the market also sells a 24 ounce bag for 5.28 which size bag is better to buy
Answer:
Bag 2
Step-by-step explanation:
Given
Bag 1:
[tex]14\ ounce = 3.50[/tex]
Bag 2:
[tex]24\ ounce = 5.28[/tex]
Required
Which is a better buy
To get which buy is better, we first get the unit price of each bag.
[tex]Unit\ Price = Amount/Size[/tex]
For bag 1:
[tex]Unit\ Price = 3.50/14[/tex]
[tex]Unit\ Price = 0.25[/tex]
For bag 2:
[tex]Unit\ Price = 5.28/24[/tex]
[tex]Unit\ Price = 0.22[/tex]
The best buy is the one with smaller unit price
Hence, bag 2 is better to buy

Mr. Thompson plans to invest $7,500 in a savings account that earns 2.75% simple annual interest. If he makes no other deposits or withdrawals, how much money will Mr. Thompson's account be worth after 10 years.
Answer:
Mr. Thompson's account be worth $9,562.50 after 10 years
Step-by-step explanation:
Simple Interest
Interest is calculated on the original principal only of a loan or on the balance of an account.
Unlike compound interest where the interest earned in the compounding periods is added to the new principal, simple interest only considers the principal to calculate the interest.
The interest earned is calculated as follows:
I=P.r.t
Where:
I = Interest
P = initial principal balance
r = interest rate
t = time
Mr. Thompson plans to invest P=7,500 in a savings account that earns r=2.75% = 0.0275.
The interest earned in t=10 years is calculated now:
I=7,500*0.0275*10
I=2,062.50
Now we add the interest to the principal:
A = $7,500 + $2,062.50
A = $9,562.50
Mr. Thompson's account be worth $9,562.50 after 10 years

Find the measure of the indicated angle to the nearest degree.
?= __∘
Answer:
x = 30°
Step-by-step explanation:
Use the sine rule:
Find the values of x and y.
(10x – 4)º
16yº
(18y – 18)°
6(x + 2)°
Answer:
The value of x is 4 and the value of y is 9
Step-by-step explanation:
In the attached pictures we can see that two lines are intersecting with each other and four angles are form. The angles opposite to each other are also called vertical angles.
The opposite pairs of angles are:
(10x-4)° and 6(x+2)°
(18y-18)° and 16y°
When two lines intersect each other, the vertical angles formed are congruent(Can also be called equal in measurement)
So,
[tex]10x-4=6(x+2)\\10x-4 = 6x+12[/tex]
Subtracting 6x from both sides
[tex]10x-4-6x = 6x+12-6x\\4x-4 = 12[/tex]
Adding 4 on both sides
[tex]4x-4+4 = 12+4\\4x = 16[/tex]
Dividing both sides by 4
[tex]\frac{4x}{4} = \frac{16}{4}\\x = 4[/tex]
AND
[tex]18y-18=16y[/tex]
Adding 18 on both sides
[tex]18y-18+18 = 16y+18\\18y = 16y+18[/tex]
Subtracting 16y from both sides
[tex]18y-16y = 16y+18-16y\\2y = 18[/tex]
Dividing both sides by 2
[tex]\frac{2y}{2} = \frac{18}{2}\\y = 9[/tex]
Hence,
The value of x is 4 and the value of y is 9

A mutual fund company offers its customers a variety of funds: a money-market fund, three different bond funds (short, intermediate, and long-term), two stock funds (moderate and high-risk), and a balanced fund. Among customers who own shares in just one fund, the percentages of customers in the different funds are as follows: Money-market 25% High-risk stock 10% Moderate-risk stock 15% Short bond 12% Intermediate bond 7% Long bond 8% Balanced 23% A customer who owns shares in just one fund is randomly selected. a) What is the probability that the selected individual owns shares in the balanced fund? For your answer, please report the answer in decimals. For example, 50% would be submitted as .5.
Part b and c are missing and they are;
b. What is the probability that the individual owns shares in a bond fund? c. What is the probability that the selected individual does not own shares in a stock fund?
Answer:
A) P(balanced fund) = 0.23
B) P(bond fund) = 0.27
C) P(no stock fund) = 0.75
Step-by-step explanation:
We are given the percentages of customers in the different funds as follows:
Money-market: 25%
High-risk stock: 10%
Moderate-risk stock: 15%
Short bond: 12%
Intermediate bond: 7%
Long bond: 8%
Balanced: 23%
A) From the percentages given, we can see that the balanced fund is 23%.
Thus,this represents the probability as addition of all the given percentages gives 100%
Thus, probability that the selected individual owns shares in the balanced fund is;
P(balanced fund) = 23% = 0.23
B) From the percentages given, bond funds given are;
Short bond: 12%
Intermediate bond: 7%
Long bond: 8%
Thus,
probability that the individual owns shares in a bond fund is;
P(bond fund) = 12% + 7% + 8%
P(bond fund) = 27% = 0.27
C) Probability that the selected individual doesn't own shares in a stock fund is;
P(no stock fund) = 1 - P(stuck fund)
P(stuck fund) = High-risk stock +
Moderate-risk stock = 10% + 15% = 25% = 0.25
Thus;
P(no stock fund) = 1 - 0.25 = 0.75

Tyler gathered data from 12 recent basketball games about the number of points he scored, the number of points his teammate Nolan scored, and the total number of points his team scored. He displayed the data in two scatter plots.
Does either scatter plot indicate a positive correlation between the variables?
Answer:
Only plot B
Step-by-step explanation:
Answer:
Only Plot B
Step-by-step explanation:
The points in plot A are randomly scattered, and there is no recognizable pattern. So, this plot indicates no correlation between the points Tyler scored and the points Nolan scored.
In plot B, the total points Tyler’s team scored appear to increase as the points Tyler scored increase. This pattern indicates a positive correlation between the two variables.
So, only plot B indicates a positive correlation.
