Answer:
3
Step-by-step explanation:
"Rate of change" is the real-world problem way of saying "slope."
So whenever a question asks you to find "rate of change", simply look for the slope.
y = mx + b
e = 3h + 200
mx = slope/rate of change
So, 3 would be your answer.

what percent of 120 is 66?
Answer:
55%
Step-by-step explanation:
66
120
x 100% = 55%
Answer:
66 is 55% of 120
Step-by-step explanation:
66 = 120 * x%
percent just means out of 100
for example, 20% is equal to 20/100
so, x% is x/100
66 = 120 * x/100
66/[tex]\frac{x}{100}[/tex] = 120
66 * 100/x = 120
6600/x = 120
cross multiply
6600/x = 120/1
6600 * 1 = x * 120
6600/120 = x
x = 55
What is the rate of change of the function y= -7?
Answer:
Zero
Step-by-step explanation:
Average rate of change can also be called as gradient or change in the respective variable , in this case we need the average rate of change of y which has the function y = -7
Since this is a linear function and if we draw the graph of y = -7 the graph would be parallel to the x-axis, and any line parallel to the x-axis has slope of zero , hence the average rate of change of the function y = -7 is zero

A store is having a 20%-off sale on all pairs of shoes. Kurt wants to buy a pair of shoes that have a regular price of x dollars. The sales tax is 7%. Which expression represents the final price of the shoes?
Answer:
[tex]\$ \ \dfrac{428}{500}x[/tex]
Step-by-step explanation:
Regular price of a pair of shoes = $[tex]x[/tex]
Discount offered = 20%
Amount of discount offered = 20% of $[tex]x[/tex]
Discounted price = Regular price - Amount of discount
Discounted price = $[tex]x[/tex] - 20% of $[tex]x[/tex] = 80% of $[tex]x[/tex] = [tex]\$ \frac{4}{5}x[/tex]
Now, it is given that there is a sales tax of 7% as well on the price.
Sales tax is applied on the discounted price.
Therefore, sales tax = 7% of [tex]\$ \frac{4}{5}x[/tex]
Final Price after applying the sales tax = [tex]\$ \frac{4}{5}x[/tex] + 7% of [tex]\$ \frac{4}{5}x[/tex]
[tex]\Rightarrow 107\%\ of\ \$\ \ \dfrac{4}{5}x[/tex]
[tex]\Rightarrow \$ \ \dfrac{428}{500}x[/tex]
Therefore, the expression to represent the final price of the pair of shoes:
[tex]\$ \ \dfrac{428}{500}x[/tex]

Answer: (-3, 0) and (-2, 0)
Step-by-step explanation:
1. Factor
(x+3)(x+2) = 0
2. Check if your factoring is correct
x^2 + 3x +2x + 6 = 0
x^2 + 5x + 6 = 0
3. Look back at factors and use them to find the zeros
(x+3) - > (-3, 0)
(x+2) -> (-2, 0)

Answer:
m∠A = 74°
m∠T = 32°
Step-by-step explanation:
m∠A must be m∠C due to symmetry.
m∠C + m∠A + m∠T = 180° because it's a triangle.
m∠T = 180 - m∠C - m∠A = 32

C. Use a compass to draw one arc with point M at the center and intersecting point N.
Step-by-step explanation:
I took the test and got it right.
Your welcome :)
Using a compass, draw one arc with point M at the center and point N intersecting it as the first step in the typical construction of the perpendicular bisector of MN. Option C is correct.
What are perpendicular bisectors?Lines that cut through the middle of each side of a triangle and are perpendicular to the specified side are known as the perpendicular bisectors of the triangle.
The standard construction of the perpendicular bisector of MN will be,
Step 1: Sketch a line segment with any appropriate length, XY.
Step 2: Using a compass, draw arcs above and below the line segment, with X serving as the center and XY's width greater than 50%.
Step 3: Carry out Step 2 but use Y as the center. Step 4: Write "P" and "Q" next to the junction points.
Thus, using a compass, draw one arc with point M at the center and point N intersecting it as the first step in the typical construction of the perpendicular bisector of MN. Option C is correct.

Step-by-step explanation:
A rhombus is a quadrilateral where all sides are equal in length. This means that [tex]\overline R \overline O = \overline O \overline C[/tex].
From this, we can write:
[tex]2x-15=x+6[/tex]
[tex]x-15=6[/tex]
[tex]x=21[/tex]
Now that we have solved for [tex]x[/tex], we can find the length of [tex]\overline R \overline O[/tex] by using substitution:

Members of a baseball team raised $1199.50 to go to a tournament. They rented a bus for $830.50 and budgeted $30.75 per player for meals. Determine the number of players the team can bring to the tournament.
Answer:
The team can bring 12 players to the tournament.
Step-by-step explanation:
With the information provided, you can say that cost of going to a tournament is equal to the cost of renting the bus plus the result of multiplying the cost per player for meals for the number of players, which is:
c=830.50+30.75x, where:
c is the cost of going to a tournament
x is the number of players
Now, you can replace c with $1199.50 that is the total amount they raised and solve for x:
1199.50=830.50+30.75x
1199.50-830.50=30.75x
369=30.75x
x=369/30.75
x=12
According to this, the answer is that the team can bring 12 players to the tournament.
