The graph below shows the prices of different numbers of boots at a store: A graph is shown. The values on the x axis are 0, 2,
kobusy [5.1K]

Answer:

b=12.50p

Step-by-step explanation:

Given :

x                 y

0                 0

2                 25

4                 50

6                 75

8                 100

10                125

To Find: Which equation can be used to determine p, the cost of b boots?

Solution :

Using point slope form Find the equation of line of the given coordinates

Let (x_{1} , y_{1})=(0,0)

Let (x_{2} , y_{2})=(2,25)

So, formula : y-y_{1} =\frac{y_{2}- y_{1}}{x_{2}- x_{1}} *(x-x_{1})

y-0 =\frac{25-0}{2-0} *(x-0)

y= 12.50x

Now we are given that cost of b boots is p

Since we are given that x axis is Number of Boots and y in price

So in the equation put x = b and y = p

So, equation : b=12.50p

Hence Option 4 is correct

Alisiya [41]
77+72=149 
149/2=74.5 
through the process of elimination, I found that Jim needs to get an 88 or higher to receive an average of 79 or greater. 

77+72+88=237 
237/3=79

Please please help me with this.
puteri [66]

Answer:

B

Step-by-step explanation:

Since the inequality is < then the line separating the shaded and plain regions will be broken.

Thus graph A or B

Choose a test point in each shaded region and check validity of solution

From A choose (0, 2), then

2 < 0 + \frac{4}{7} → 2 < \frac{4}{7} ← False

From B choose (0, - 2), then

- 2 < 0 + \frac{4}{7} → - 2 < \frac{4}{7} ← True

Thus the graph representing the inequality is B
