If you are finding X out of those 2 numbers it would be
X= -2.5

4x+8 = 2x+3> 2x = -5> so X= -2.5
-2x -8 -2x -8
But if you are trying to find x as a whole it is
X=28

(4x+8) +(2x+3) =6x+11>
6x + 11 = 180> 6x = 169> so X= 28
-11 -11. 6÷ 6÷

Which value of b would make x²+bx-30 factorable? A. -31 B. -17 C. 11 D. 13

dimulka [17.4K]

Answer:

D. 13

Step-by-step explanation:

well since it's a quadratic equation, it can be written in the form of ax²+bx+c=0. So we have a=1, b=b and c= -30. Also the roots are given by the equation-

x= -b± $\sqrt{b^{2}-4ac}$ /2a. So all I did was put the number from the choices which would satisfy the sqrt part and that turned out to be 13 since $\sqrt{13^{2}-4*1*(-30)$ = $\sqrt{289}$ = 17. So b=13.

Write the equation in standard form y = -10x + 6

Mumz [18]

Step (1) Flip the equation

−10x+6=y

Step (2) Add -6 to both sides

−10x+6+−6=y+−6

−10x=y−6

Step (3) Divide both sides by -10

−10x−10=y−6−10

ANSWER
$x = \frac{ - 1}{10} y + \frac{3}{5}$
