The slope is of $13, which means that each new sign costs $13.
-----------------
A linear function has the following format:
In which
- m is the slope, which is the rate of change, that is, how much y changes when x changes by 1.
- b is the y-intercept.
-----------------
- In the linear function in this problem, we have two points (x,y): (5,72) and (15,202).
- The slope is given by the <u>change in y divided by the change in x</u>, thus:
- The slope is of $13, which means that each new sign costs $13.

Answer:
y = 45
Explanation:
(8)(10)(2)y = 7200
[ Simplify both sides of the equation ]
160y = 7200
[ Divide both sides by 160 ]
160y / 160 = 7200 / 160
y = 45
Check:
8(10)2(45) = 7200
51 ÷ 3 = 17
17 were in the van
51 - 17 = 34
34 were in the bus
Answer:
Cups of carrot needed for 9 servings = 4.5 cups
Step-by-step explanation:
A recipe for sesame chicken calls for cup of chopped carrots
recipe 2 is for 4 servings
That is
2 cups of carrot = 4 servings
2 : 4
= 1 : 2
1 cup of carrot = 2 servings
how many cups of
carrots are needed for 9 servings?
Let x= number of carrot needed for 9 servings
1 : 2 = x : 9
1 /2 = x/ 9
Cross product
1*9 = 2*x
9=2x
Divide both sides by 2
9/2 = x
x= 4.5 Or 4 1/2
Answer:
-2
