Answer its urgent! i already tried and got it wrong!

the triangles are similar.

what is the value of x?

enter your answer in the box.

x =

x=13

Step-by-step explanation:

We can use proportions.  Take the small side over the large side

x                5

=

52            20

Using cross products

20x = 5*52

20x = 260

Divide by 20

20x/20 = 260/20

x= 13

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
