Suppose a crew member at an unloading dock can unload 3 trucks per hour and have already unloaded 17 trucks. which equation can be used to medel the number of trucks the crew unloads after h hours?
a. 3h+17
b. 3h=17
c. 17h-3
d. 17h+3

A. 3h+17

Step-by-step explanation:

Given,

The initial number of unloaded trucks = 17,

Also, 3 trucks per hour can be uploaded,

So, the additional number of uploaded truck after h hours = 3h,

Hence, the total number of uploaded trucks after h hours = Initial uploaded trucks + additional trucks

= 17 + 3h

Which is the required equation,

Option A is correct.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
