Answer:
Given coordinates on the graph is (4,0), (8,10), (12,20).
We need to find the rate of change for the function graphed.
Actually rate of change is the second name of slope.
So, we need to find the slope between given coordinates.
We know slope formula
Let us choose first two coordinates (4,0), (8,10).
(x1,y1) = (4,0) and (x2,y2) = (8,10).
Plugging values of x1,x2,y1 and y2 in slope formula, we get
Slope=
Therefore, rate of change is 5/2 or $2.5 earned per bookmark sold.

The slope of the shown line is Zero, because it is parallel to x - axis ~
The slope of the given graph is zero
By considering the graph shown, the graph is horizontal.
Note that
Horizontal graphs are parallel to the x axisThe slope of a line is the ratio of the change in the y-coordinate to the x-coordinateSince there is no change in the y-coordinate because the graph is parallel, the change in the y-coordinate is zero.
Therefore, the slope of the given graph is zero

Use the graph. Which equation is true from the information in the graph?
A) a/b = c/d
B) a/b = d/c
C) ab = cd
D) a + b = c + d
Using the similarity of triangles, it exists seen that the true equation exists given by:
A) a/b = c/d
What are similar triangles?Two triangles exist similar when they have the same angles. Then, the measurements of the sides adjacent to similar angles exist proportional.
In this problem, about the location of the right angle of the triangle, we have that:
a/c = b/d
a/b = c/d
Therefore, the correct answer is option A) a/b = c/d.

Jessica and Laura are shopping for new clothes at a store that is going out of business. The different brands of shirts are all the same price, and the same goes for pants. At the store, Jessica purchases 3 shirts and 4 pairs of pants for a total of $90. Laura purchases 4 shirts and 2 pairs of pants for a total of $70.
Given Jessica and Laura's expenditure on shirts and pants, the equation to solve for the price of each shirts and pants is:
3s + 4p = 90
4s + 2p = 70
Let
Cost of each shirts = s
Cost of each pants = p
Jessica:
3s + 4p = 90 (1)
Laura:
4s + 2p = 70 (2)
Multiply (2) by 2
8s + 4p = 140 (3)
8s + 4p = 140 (3)3s + 4p = 90 (1)
Subtract (1) from (3) to eliminate p
8s - 3s = 140 - 90
5s = 50
s = 50/5
s = $10
substitute s = 10 into (1)
3s + 4p = 90 (1)
3(10) + 4p = 90
30 + 4p = 90
4p = 90 - 30
4p = 60
p = 60/4
p = $15
Therefore, the cost of each shirts is $10 and the cost of each pants is $15

The greatest weight a moving truck can carry is 1,600 pounds. The truck is loaded with a
piano that weighs 400 pounds. Boxes that weigh 50 pounds each will also be loaded into the
truck.
Which inequality represents all possible values of x, the number of these boxes that can be
loaded into the moving truck?
Answer:
1600=50x+100(thats the equation) ACTUAL ANSWER: X=30
Step-by-step explanation:
The inequality represents all possible values of x, which will be 1600=50x+100.
What is linear inequality?Linear inequalities involve at least one linear algebraic expression. A polynomial of degree 1 is compared to another algebraic expression of degree less than or equal to 1.
The greatest weight a moving truck can carry = is 1,600 pounds
Weight of the piano = 400 pounds
Weight of box = 50 pounds
The inequality represents all possible values of x will be;
1600 = 50x+100
Hence the inequality represents all possible values of x, the number of these boxes that can be loaded into the moving truck will be 1600=50x+100.

The equation that match the table attached is
B. y = -5(2⁻ˣ) + 4
How to match the table with the equationBy analyzing the given equations we can see that option B match the table and this is shown below
Using calculator to set the equation shows that
for x = -2
y = -5(2⁻ˣ) + 4 = 2.75
for x = -1
y = -5(2⁻ˣ) + 4 = 1.5
for x = 0
y = -5(2⁻ˣ) + 4 = -1
for x = 1
y = -5(2⁻ˣ) + 4 = -6
Based on the comparison, the equation that corresponds to the table is:
OB.y = -5(2⁻ˣ) + 4
