I would say its D, but im not 100 percent sure
2x - 3y = -12 ⇒ 2x - 3y = -12⇒ 2x - 3y = -12
x + y = 1 ⇒ 2(x + y) = <u>1⇒ 2x + 2y = 1</u>
y = -11
2x - 3y = -12
2x - 3(-11) = -12
2x + 33 = -12
<u> - 33 - 33</u>
2x = -45
<u> 2x</u> = <u>-45</u>
2 2
x = -22.5
(x, y) = (-22.5 , -11)
Answer:
Step-by-step explanation:
(B^2)(B^4) = B^(2+4)= B^6
answer is B
Answer: 3.285?
I just multiplied 1.5 and 1.19, then added the product and his height at the age of 12 so, therefore i got 3.285 as a answer
The square root of 144x^2 = 12 x
and square root of + 81 = 9 or -9
if this polynomial were a perfect square then its factors would be
(12x - 9)(12x - 9)
but its not a perfect squre because (12x - 9)(12x - 9) = 144x^2 - 216x + 81.
