When 4(0.5x+2.5y-0.7x-1.3y+4)is simplified, what is the resulting expression?

Resulting expression is - 0.8x + 4.8y +16.

Step-by-step explanation:

Given :  4(0.5x+2.5y-0.7x-1.3y+4).

To find  : what is the resulting expression.

Solution : We have given that  4(0.5x+2.5y-0.7x-1.3y+4).

First we will solve the parenthesis by combine like terms:

4( 0.5x - 0.7x +2.5y -1.3y +4).

4( - 0.2x + 1.2y +4).

Now distributes 4 over parenthesis's terms

- 0.8x + 4.8y +16

Therefore, Resulting expression is - 0.8x + 4.8y +16.

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?
