Answer:
7 x 13 expanded form is y = 7 x 13 ........ 7 dived by 13 in expand form is y=7 dived by 3
Step-by-step explanation:
if that's not what your looking for sorry :)
Six times twelve minus 4 equals forty-eight
<span>-16x^3+4x=0
-4x(4x^2 - 1) = 0
-4x(2x+1)(2x - 1) = 0 (factor using a^2 - b^2 = (a+b)(a-b))
-4x = 0; x =0
2x +1 = 0;x = -1/2
2x - 1 =0; x = 1/2
answer: x = 0, x = 1/2 and x = -1/2</span>
Answer:
A) -7
Step-by-step explanation:
2x + 5y + 30 = 0
Let x = 5/2
Substitute into the equation
2(5/2) +5y +30 =0
5+5y+30=0
Combine like terms
35 +5y =0
Subtract 35 from each side
35-35 +5y = -35
5y=-35
Divide by 5
5y/5=-35/5
y = -7
