Answer:

9

Step-by-step explanation:

Hey There!

So for this problem all we have to do is plug in the given values into the expression so now we have

5(3) - 2(4)  - -2

5x3=15

-2x4=-8

now we have

15-8-(-2)

15-8=7

7-(-2)

remember when you subtract a negative number the two negative signs cancel out and turn into a positive so instead of

7--2 it would be 7+2

7+2=9

so the answer is 9

What is the equation of a line that passing through points (-2, 5) and (3, 25)
Llana [10]
\bf (\stackrel{x_1}{-2}~,~\stackrel{y_1}{5})\qquad &#10;(\stackrel{x_2}{3}~,~\stackrel{y_2}{25})&#10;\\\\\\&#10;% slope  = m&#10;slope =  m\implies &#10;\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{25-5}{3-(-2)}\implies \cfrac{25-5}{3+2}&#10;\\\\\\&#10;\cfrac{20}{5}\implies 4&#10;\\\\\\&#10;% point-slope intercept&#10;\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-5=4[x-(-2)]&#10;\\\\\\&#10;y-5=4(x+2)\implies y-5=4x+8\implies y=4x+13
