Answer
C and A
Step-by-step explanation:
4(x-8)+12 equal 2(2x-9)
(Answer explained)
4(x-8)+12=2(2x-9)
We move all terms to the left:
4(x-8)+12-(2(2x-9))=0
We multiply parentheses
4x-(2(2x-9))-32+12=0
We calculate terms in parentheses: -(2(2x-9)), so:
2(2x-9)
We multiply parentheses
4x-18
Back to the equation:
-(4x-18)
We add all the numbers together, and all the variables
4x-(4x-18)-20=0
We get rid of parentheses
4x-4x+18-20=0
We add all the numbers together, and all the variables
-2!=0
There is no solution for this equation

Answer:
f(2) = -2
Step-by-step explanation:
plug in 2 to wherever x is in this statement:
f(2) = -2(2^2) - 2(2) + 10
f(2) = -2(4) - 4 + 10
f(2) = -8 - 4 + 10
f(2) = -2

-x³-x²+5x-3 find each polynomial by degree and number of terms
Answer:
- (x-1)^2 x (x+3) is correct ans
Step-by-step explanation:
rewrite the expression
-x^3 - x^2 + 5x - 3
factor the expressions
x^3 + x^2 -2x^2 +2x=3x-3
factor the expression
-x^2 x (x-1)-2x x (x-1) +3 (x-1)
rewrite the expression
-(x-1) x (x^2 + 2x-3)
rewrite
-(x-1) x (x^2 + 3x - x - 3)
factor the expression
-(x-1) x (x^2+2x-3)
factor the expression
-(x-1) x (x x(x+3)-(x+3)
write in exponential form
-(x-1) x (x+3) x (x-1)
solution:
-(x-1)^2 x (x+3)

An angle 0 is drawn on the unit circle such that its terminal ray is in the second quadrant.
if sin 0 = 0.809, then what must be true about sin(-0)?
Answer:
sin(-θ) = -0.809
Step-by-step explanation:
To find this, simply perform the operation that is being asked, make theta negative.
If you want to find out what theta is in the first place, do this:
θ = arcsin(0.809)
θ = 54
Then to find sin of negative theta, substitute:
sin(-θ), or, sin(-54)
should equal to:
sin(-θ) = -0.809

Lucy drove 120 miles in 5 hours if she drove at a constant rate how far does she travel in one hour
Answer:
Lucy drives 24 miles in one hour
Step-by-step explanation:
if she drives 120 miles in 5 hours we need to see how much she drives per hour.
In that case, we will be dividing. So, the equation would like this:
120➗ 5=24
Lucy drives 24 miles in an hour
