Hello everybody. Can somebody please help me on this math question

Nutka1998 [239]

Answers:

<em>See below.</em>

Step-by-step explanations:

(A) This equation evaluates the cost to ship 100 lbs of wheat, which equals $130:

C(100) = 1.28(100) + 2

C(100) = 128 + 2

C(100) = 130

(B) The cost to ship 250 lbs of wheat would be $322:

C(250) = 1.28(250) + 2

C(250) = 320 + 2

C(250) = 322

(C) If you had $50, you could ship 37.5 lb of wheat:

C(x) = 50

C(x) = 48 + 2

C(x) = 1.28(37.5) + 2

What is the slope intercept form when m = 1/2 & b = 89 ?<br> Helppppppppp

Zina [86]

Answer:

$y = \frac{1}{2}x + 89$

Step-by-step explanation:

slope-intercept form: y = mx + b

y = (x , y)

x = (x , y)

m = slope = 1/2

b = y-intercept = 89

Plug in the corresponding numbers & variables to the corresponding variables:

y = (1/2)x + 89

$y = \frac{1}{2}x + 89$ is your answer.

20 is how much less than 30? What percent less?

LenKa [72]

Answer:

33.3333% decrease

Step-by-step explanation:

Percent change formula: $\frac{(x-y)}{|y|} *100$ , where x is the new value and y is the starting value.

Plug in values and solve:

$\frac{20-30}{30} *100\\\frac{-10}{30} *100\\-0.3333*100\\$

-33.3333% change, or a 33.3333% decrease.

Given that f(x) = 6x + 2 and g(x) =2x+4 over 5 solve for g(f(1))

Lady bird [3.3K]

F(1)=6(1)+2
= 6+2
=8

g(f(1))= 2x/5 +4/5
= 2(8)/5 +4/5
= 16/5 +4/5
= 20/5
=4
