The table represents a linear function. What is the slope of the function? O -10 16 O5 O5 O10 24
Answer: 5
Step-by-step explanation:
I got it right on the test.
The slope of the function is 5.
The correct option is C.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
We can take two points from the table as (-4, -16) and (-2, -6).
So, slope of the function is
= (-6 - (-16))/ (-2 - (-4))
= (-6 + 16)/ (-2 +4)
= 10 /2
= 5
Thus, the required slope is 5.

Gerardo’s texting plan cost $20 per month, +0.05 per text message that is sent or received. Amelia’s plan cost $10 per month and $0.25 per text. Using the graph below, which statement is true?
Step-by-step explanation:
Let's turn that into a linear system:
\{ {{y=0.05x+20} \atop {y=0.25x+10}} .{y=0.25x+10y=0.05x+20.
Set the equations equal to each other and solve:
0.05x+20=0.25x+100.05x+20=0.25x+10
0.2x=100.2x=10
x=50x=50
We then plug in to get yy :
0.25(50)+10=22.50.25(50)+10=22.5
The solution to the system is \{ {{x=50} \atop {y=22.5}} .{y=22.5x=50. .
Now, let's turn our attention to the statements.
The first one is false: Emilia's rate is higher, and the two plans cost the same at 50 texts, after which point Hiroto's plan becomes cheaper!
The second one is also false: we already figured out that the lines intersect at x=50x=50 .
The third statement is also false: as above, the lines intersect at x=50x=50 .
The fourth statement is true: the lines intersect at x=50x=50 .
In conclusion, the fourth statement - "Both plans cost the same when 50 texts are sent" - is true.

The temperature in Coldspot is -7o F and increasing 2.5o per hour. The temperature in Frostberg is 19 degrees F and decreasing 4 degrees per hour.
a. How long will it be until the temperatures are the same?
b. What will the temperature be then?
Answer:
It will take 4 hours for the temperatures to be the same. The temperature will be 3° at that time.
Step-by-step explanation:
Coldspot = -7 + 2.5x
Frostberg = 19 - 4x
First, we are going to input our values into the variable in a table.
Coldspot Frostberg
1 -7 + 2.5(1) = -4.5 19 - 4(1) = 15
2 -7 + 2.5(2) = -2 19 - 4(2) = 11
3 -7 + 2.5(3) = 0.5 19 - 4(3) = 7
4 -7 + 2.5(4) = 3 19 - 4(4) = 3
It will take 4 hours for the temperatures to be the same. The temperature will be 3° at that time.

Yesterday, Kate gave exactly fourteen haircuts
and made $50.00. If she charged $5.00 for adults'
haircuts and $2.50 for children's haircuts, how
many children's haircuts did she give?
A) 5
B) 6
C) 7
D) 8
Answer:
D) 8
Step-by-step explanation:
8 x 2.5 = 20
and the rest is adult haircuts
6 x 5 = 30
Answer:
D) 8 Children’s Haircuts
Step-by-step explanation:
Let a represent the amount of adult haircuts and c represent the amount of child haircuts.
We know that she gave exactly 14 haircuts. So:
[tex]a+c=14[/tex]
We also know that she made $50.00. Therefore, the price of each haircut times their respective amounts will total $50. So:
[tex]5a+2.5c=50[/tex]
This is now a system of equations.
We can solve this using substitution. From the first equation, let’s subtract c from both sides:
[tex]a=14-c[/tex]
Now, we can substitute this into the second equation for a. This yields:
[tex]5(14-c)+2.5c=50[/tex]
Distribute:
[tex]70-5c+2.5c=50[/tex]
Combine Like Terms:
[tex]70-2.5c=50[/tex]
Subtract 70 from both sides:
[tex]-2.5c=-20[/tex]
Divide both sides by -2.5:
[tex]c=8[/tex]
Therefore, Kate gave 8 children’s haircuts.
This means that she gave [tex]14-8=6[/tex] adult haircuts.
So, our answer is D. She gave 8 children’s haircuts.

Mei subscribed to a magazine at a rate of $24 for 12 issues. When she placed her order, Mei used a coupon that added 3 free bonus issues to her subscription. How did the coupon impact the cost per issue of Mei’s subscription?
O The coupon lowered the cost per issue by $0.40.
O The coupon lowered the cost per issue by $1.38.
O The coupon raised the cost per issue by $0.13.
O The coupon raised the cost per issue by $0.67.
Answer:
A
Step-by-step explanation:
Originally, Mei pays $24 for 12 issues.
Therefore, the cost per issue is:
[tex]c=\frac{\$24}{12\text{ issue}}=\$2\text{ per issue}[/tex]
With the coupon, Mei pays the same amount of $24 but for 15 issues.
So, the cost per issue now is:
[tex]c=\frac{\$24}{15\text{ issues}}=\$1.60\text{ per issue}[/tex]
Therefore, the coupon lowered the price of the issue by $0.40.
Our answer is A.
Answer: The coupon lowered the cost per issue by $0.40.
Original price of issue: $2
24 ÷ 12 = 2
Mei added 3 more issues, but she still pays $24.
The answer is A.

Mia says that when you rearrange 3a - p = m to make a the subject of the formula you get:
a = m - p / 3
Mia is wrong. Explain and show her how to do the
question correctly.
Answer:
[tex]a =\frac{m+p}{3}[/tex]
Step-by-step explanation:
[tex]3a - p = m[/tex]
→ First plus p to both sides to isolate 3a
[tex]3a = m+p[/tex]
→ Divide both sides by 3 to isolate a
[tex]a =\frac{m+p}{3}[/tex]
Answer:
see explanation
Step-by-step explanation:
Mia is wrong in that she has subtracted p from both sides instead of adding p to both sides.
Given
3a - p = m ( add p to both sides )
3a = m + p ( isolate a by dividing both sides by 3 )
a = [tex]\frac{m+p}{3}[/tex]

A triangle has angle measures 23° and 35°. What is the measure of the third angle
The angles in a triangle add up to 180 degrees, so the third angle must be 180 - 23 - 35 ---> 157 - 35 --> 122.
122 degrees.
Hope this helps!
The measure of the third angle is 122° and the triangle is an obtuse angle triangle.
What is a triangle?A triangle is a 2D figure joined by the lines of three non-colinear points.
There are three types of triangles they are:- Equilateral triangle, Isosceles triangle, and Scalene triangle.
We know that sum of all the interior angles of a triangle is 180°.
Given two angles which measure 23° and 35° and assuming the third angle to be x°.
∴ 23° + 35° + x° = 180°.
58° + x° = 180°.
x = 180° - 58°.
x = 122°.
We can conclude that the triangle is an obtuse angle triangle.
