Answer:
4x−5y=−10 hopefully this helps
It opens up. hope this helps
For
y=ax²+bx+c
the x value of the axis of symmetry is -b/(2a)
so test them
A., -b/(2a)=-(-8)/(2*-2)=8/-4=-2, yep
B. -b/(2a)=-2/(2*1/2)=-2/1=-2, yep
C. -b/(2a)=-(-16)/(2*4)=16/8=2, nope, need -2
D. -b/(2a)=-12/(2*3)=-12/6=-2, yep
answer is C
Answer:
<h3>X = 3/5 </h3>
3/5x + 3 = 6
3/5x = 6 - 5
3/5x = 1
<h3><u>Multiplying </u><u>both </u><u>the </u><u>sides </u><u>with </u><u>5x </u></h3>
3/5x (5x) = 1* 5x
3 = 5x
3/5 = X
