No he's not correct
<span>(3 – 6y2)(y2 + 2)
= 3(y2) -6(y2)(y2) - 6y2(2) </span>+ 3(2)<span>
= 3y2 -6y4 - 12y2 </span>+ 6 <span>
= -6y4 - 9y2 +6</span>
f(x) = −2x + 12, find f(x) when x = −3.
replace x = -3 then
f(-3) = (-2)(-3) + 12
= 6 + 12
=18
Answer is C) f(−3) = 18
f(p)=7/11p-10 Find f(77)
f(77) = 7/11 (77) - 10 (cancel out 77 and 11)
= 7 * 7 - 10
= 49 -10
=39
Answer is D) f(77) = 39
Answer:
x=2
Step-by-step explanation:
8x- 1/3 y = 16
when y = 0
8x = 16
x = 2
x-intercept (2,0)
2x + 50 > = 100 (thats greater then or equal)
2x > = 100 - 50
2x > = 50
x > = 50/2
x > = 25
minimum number is 25
