Can someone me with this problem? i don’t know how to do it. you! : )

line K:  y  = -1.25 X + 3.5

function line J:     y = 0.8 X + 6.625

Step-by-step explanation:

slope of line m: Sm = (2-(-1)) / (5 - (-3)) = 3/8

line n // line m: slope N = Slope M

function line n : f(x) = 3/8 X + b

∴ 5 = 3/8 x 4 + b (y intercept of line N)

b = 5 - 3/2 = 7/2

fuction of line K: y=mx + b    y= (6 - 3.5) / (-2 - 0) X  + 3.5

line K:  y = -2.5/2 * X + 3.5 = (-5/4) * X + 3.5

line J perpendicular to line K, so slope of line J equals to negative reciprocal of line K : 4/5

fuction of line J:   y = 4/5 * X + B

6 = 4/5 * (-2) + b

b= 6- (- 8/5) =6+5/8

function line J:     y = 4/5 * X + 6 5/8

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.

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
