Solving systems of equations by graphingStep-by-step explanation:
Where the 2 lines intersect is the solution set to the systems of equations.
If the lines are the same, they will have infinite solutions (will always intersect).
If the lines are parallel, they will have no solutions (will never intersect).
According to the graph, we see that the lines are parallel. Therefore, the systems has no solutions.

Answer:
A, y-intercept = (0,24)
Step-by-step explanation:
The y intercept is the one without a variable. You have to solve to find it in the other options.
Answer:
The first choice would be the best one.
Step-by-step explanation:
The y intercept occurs when x = 0 of the given polynomial.
All 3 answers will give you the correct answer. The y intercept is (0,24)
but the first one will be the quickest because all you need to do to find it is just eliminate any term with x in it.
2x^2 when x = 0 is 0
16x when x = 0 is 0.
That only leaves m(0) = 24 found just by looking at it.
The second one also works. 2 (0+4)^2 - 8 = 32 - 8 = 24
And the third one as well 2(6)(2) = 24
If y varies inversely as x. Using the coordinates (5, 3) and (x, 2.5), find the missing value x.
Answer:
(6, 2.5 )
Step-by-step explanation:
Given y varies inversely as x then the equation relating them is
y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation
To find k substitute the coordinate point (5, 3 ) into the equation, that is
3 = [tex]\frac{k}{5}[/tex] ( multiply both sides by 5 )
15 = k
y = [tex]\frac{15}{x}[/tex] ← equation of variation
Using (x, 2.5 ) with y = 2.5 , then
2.5 = [tex]\frac{15}{x}[/tex] ( multiply both sides by x )
2.5x = 15 ( divide both sides by 2.5 )
x = 6
Thus point is (6, 2.5 )
There is an assortment of shirts in store at the mall. The shirts come in 4 different colors. There are 36 red shirts, 12 blue shirts, 42 black shirts, and 60 white shirts. What is the ratio of black shirts to blue shirts?
Answer:
The ratio of black shirts to blue shirts is 7:2
Step-by-step explanation:
Ratios
A ratio is a way to compare two numbers of the same kind. We use ratios to compare things of the same type. For example the ratio of boys and girls in a class. Ratios as expressed in the form n:m.
There are 36 red shirts, 12 blue shirts, 42 black shirts, and 60 white shirts. It's required to calculate the ratio of black shirts to blue shirts. We'll use fractions to express the relationship. The fraction will divide 42 by 12:
[tex]\frac{42}{12}[/tex]
Simplifying by 6:
[tex]\frac{42}{12}=\frac{7}{2}[/tex]
Thus, the ratio of black shirts to blue shirts is 7:2
Answer:
black shirts to blue shirts is 7:2
Step-by-step explanation:
(5x² + 25x + 30)– (3x² + 6x + 3)
Notice that the second polynomial is subtracted from the first.
It's important to understand that the minus sign outside the
second set of parenthses can be thought of as a -1.
So we need to distribute the -1 through each of
the terms in the second set of parenthses.
So our problem will now look like 5x² + 25x + 30 - 3x² - 6x - 3.
Now, we combine like terms.
So we have 2x² + 19x + 27.
Subtract-3c2 + 12cd – 4d2 from 4c2 + 3cd + 2d?.
Your answer should be a polynomial in standard form.
Answer:
Subtract [tex]-3c^2 + 12cd - 4d^2[/tex] from [tex]4c^2 + 3cd + 2d^2[/tex] we get [tex]\mathbf{7c^2-9cd+6d^2}[/tex]
Step-by-step explanation:
We need to Subtract [tex]-3c^2 + 12cd - 4d^2[/tex] from [tex]4c^2 + 3cd + 2d^2[/tex]
(Note: Considering 2d^2 instead of 2d as thinking it typo error)
Subtracting from means we have to subtract [tex]4c^2 + 3cd + 2d^2 -(-3c^2 + 12cd - 4d^2)[/tex]
Subtracting:
[tex]4c^2 + 3cd + 2d^2 -(-3c^2 + 12cd - 4d^2)\\=4c^2 + 3cd + 2d^2 +3c^2 - 12cd + 4d^2[/tex]
Combining like terms (Like terms are those that have same variables like 4c^2 and 3c^2 are like terms, 3cd and -12cd are like terms, 2d^2 and 4d^2 are like terms)
[tex]=4c^2+3c^2 + 3cd-12cd + 2d^2+4d^2 \\=7c^2-9cd+6d^2[/tex]
So, Subtract [tex]-3c^2 + 12cd - 4d^2[/tex] from [tex]4c^2 + 3cd + 2d^2[/tex] we get [tex]\mathbf{7c^2-9cd+6d^2}[/tex]

Step-by-step explanation:
Stacey has earned $9 interest over the past 20 months with an initial investment of $150. What is the simple interest rate she is earning? Express your answer to the nearest tenth of a percent. (It wants me to use the formula I=Prt which I don't remember)
Answer:
3.6%
Step-by-step explanation:
We are solving the above question, using the simple interest Formula:
I = PRT
Where
I = Interest = $9
P = Principal = $150
R = Interest rate = ??
T = Time in years = 20 months
We convert this to years
12 months = 1 year
20 months = x
x = 20/12
x = 1.67 years
Hence, making R the subject of the formula
R = I/PT
R = 9/150 × 1.67
R = 9/250.5
R = 0.0359281437
Converting to percentage
R = 0.0359281437 × 100
R = 3.59281437%
R = 3.6 %
The simple interest rate she is earning is 3.6%

Answer:
-0.8 is the correct answer for this question
Step-by-step explanation:
mark me as brainliest
Answer:
t=-0.8
Step-by-step explanation:
You want to get the 't' by itself, so you will subtract 5 from both sides
5.25t=16.5t+9
Now, you want to subtract 16.5t from both sides
-11.25t=9
now you divide -11.25 from both sides.
t=-0.8

A train leaves at 0836 and arrives at 1057. It travelled at an average speed of 85 km/h. How far did it travel?
Answer:
199.75km
Step-by-step explanation:
Step one:
given data
We are told that the time of travel is from
8:36- to 10:57
which is 2 hours 21 minutes
Hence the time taken is 2.35 hours
the speed is 85km/h
Step two:
From the expression
speed= distance/time
85= distance/2.35
distance= 85*2.35
distance= 199.75km
Answer: it traveled a distance of 199.75Km
Step-by-step explanation:
From the question , Let 0836 be 8:36
and 1057 be 10:57
Time of departure= 8:36
Time of arrival = 10:57
Time traveled = 10:57- 08:36= 2 Hours 21 minutes
changing trhe time to hours becomes 21/60 = 0.35 hours + 2 HOURS = 2.35 hours
Step 2
Speed = Distance / Time
Distance = Speed x Time
=85 km/hr x 2.35 hours
=199.75Km

Yesterday, the movie theater brought in $1,440 in ticket
sales and $295.25 in food sales. Today, ticket sales were
three-fourths as much as yesterday, and food sales were
down by $33.50. Nina wrote the expression
(1440) + 295.25 + (-33.50)
to find today's total sales. Is she correct? Explain.
Answer:
No. Nina forgot to adjust ticket sales.
Step-by-step explanation:
3/4(1440) + (295.25-33.50)
=1341.75
She didn't add the 1/4 less sales from the next day, Therefore she is wrong.

I need this to be solved ASAP
Answer:
ok so
Step-by-step explanation:
8x + 7 + 7x - 2=90=>
=> 15x+5= 90
=> 15x=90 - 5=>
=> 15x =85= x= 5.6666...
Hey there!
“8x + 7 + 7x – 2 = 90”
• FIRST: COMBINE your LIKE TERMS
(8x + 7x) + (7 – 2) = 90
‘8x + 7x = 15x’
‘7 – 2 = 5x’
“15x + 5 = 90”
• SECOND: SUBTRACT by 5 on BOTH SIDES
15x + 5 – 5 = 90 – 5
CANCEL out: 5 – 5 because that gives you 0
KEEP: 90 – 5 because it helps us solve for your x-value
‘90 – 5 = 85’
NEW EQUATION:
“15x = 85”
• THIRD: DIVIDE by 15 on BOTH SIDES
15x/15 = 85/15
CANCEL out: 15/15 because that equals 1
KEEP: 85/15 because it gives us our x-value
Reduce: 85/15 and it gives us: x
Answer: x = 17/3 ☑️

What is an equation of the line that passes through the point (−6,−1) and is perpendicular to the line 6x−y=7?
Answer:
y=-1/6x-2
Step-by-step explanation:
Lets find the slope of the given line
6x-7=y,m=6
The slope of the perpendicular line would be=-1/6
Using the point-slope form y-y1=m(x-x1)
y--1=-1/6(x--6)
y+1=-1/6(x+6)
6y+6=-x-6
6y=-x-6-6
6y=-x-12
y=-1/6x-2

Which expression models her purchase? 3 b minus 35.79 35.79 + 3 b 35.79 b minus 3 35.79 minus 3 b
Answer:
Part(A): The expression which represents the number of hours Matthew played soccer in a full week is [tex]5h + 6.5[/tex]
Part(B): the expression models her purchase is [tex]35.79-3b[/tex].
Step-by-step explanation:
Consider the provided information.
Part(A):
Matthew plays soccer for h hours per day for five days and he played a soccer tournament for a total of 6.5 hours.
So the required expression is: [tex]5h + 6.5[/tex]
Where 5h represents time spent in 5 days and 6.5 is the hours of the soccer tournament.
Part(B):
Mariah purchases three hair barrettes by using a gift card.
Let the cost of each barrette is b.
So the cost of 3 barrettes is: [tex]3b[/tex]
She uses a gift card with a balance of $35.79. Therefore subtract [tex]3b[/tex] from $35.79.
Her purchase can be expressed as:
[tex]35.79-3b[/tex]
Hence, the required expression is [tex]35.79-3b[/tex].
