Answer:
x=−414
Step-by-step explanation:
Let's solve your equation step-by-step.
x
−18
=23
Step 1: Multiply both sides by -18.
x
−18
=23
(
x
−18
)*(−18)=(23)*(−18)
x=−414

Step-by-step explanation:
f(x)=x²+7
X(-2)=?
therefore X(-2)=(-2)²+7
=4+7
=11
Answer:
x = -6,6
Step-by-step explanation:
h(x)=−5x^2 +180
Assuming you want to find the zero's
0 =−5x 2 +180
Subtract 180 from each side
0-180=−5x^2 +180-180
-180 = -5x^2
Divide each side by -5
-180/-5 = -5x^2/-5
36 = x^2
Take the square root of each side
±sqrt(36) = sqrt(x^2)
±6 = x
x = -6,6
Answer:
standard form is 6x−11y=13
The answer is C. -1+-6=-7, not 7.
