What is the rate of change and initial value for the linear relation that includes the points shown in the table?
Wittaler [7]

Answer:

Initial value 12, rate of change: -2

Step-by-step explanation:

Step 1

Find the rate of change

we know that

In a linear equation the rate of change is equal to the slope

The formula to calculate the slope between two points is equal to  

m=\frac{y2-y1}{x2-x1}  

we have

A(1,10)\ B(2,8)  

Substitute the values  

m=\frac{8-10}{2-1}

m=-2  ----> rate of change

Step 2

Find the initial value

The equation of  the line into slope-point form is equal to

y-y1=m(x-x1)

Substitute

y-10=-2(x-1)

y=-2x+2+10y=-2x+12

The initial value is the value of y when the value of x is equal to zero (is the y-intercept)

y=-2*0+12=12----> initial value

What is AB to the nearest meter
sashaice [31]

Answer:

C. 15

Step-by-step explanation:

Small triangle is similar to larger one so we can use the similarity ratio to solve the question:

CE/CA = DE/AB

4/12 = 5/AB cross multiply expressions

4AB = 60 divide both sides by 4

AB = 15

How to find the discounted price example $25.00 is the original price and the discount is 15%
Alexandra [31]
Since the price is now 15% less you would first find what 15% of 25 is  by using 25*.15 and get 3.25  then you subtract that from 25 and get 25-3.25=                     $21.75
