Answer:

Q. 2)Perimeter =2(l+b)

So,

2(8x-8 +8x)=80cm(Given in Question)

= 2*16x-8=80cm

16x- 8= 80 divided by 2,

16x=40+8=48

x=48 divided by 16

X=3

Q.1) Perimeter=2(l+b)

2(2x+8 +4x)=76cm(Given in Question)

2* 6x +8=76

6x+8= 76 divided by 2, 38

6x= 38-8, 30

x= 30 divided by 6 = 5

X=5

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
