PLEASE HELP I NEED HELP ALSO I WILL MARK BRAINLIEST

see below

Step-by-step explanation:

Let C be at (0,0)

D is at (7,12)

The slope is

m = (y2-y1)/(x2-x1)

    = (12-0)/(7-0)

   = 12/7

The equation of the line is y = mx+b where m is the slope and b is the y intercept

y = 12/7x +b

The y intercept is (0,0)

y = 12/7x +0

y = 12/7x

The domain is the input values or the values that x can take

X goes from 0 to 7

Domain: {0≤x≤7}

The range is the output values or the values that y can take

y goes from 0 to 12

Range: {0≤y≤12}

step-by-step explanation:

|ab| = 1.4 = 4

h = 1.4 = 4

a(abc) area = 4.4 = 16/2 = 8

area of abc = 8 cm^2

good luck ! ; )

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
