Answer:
A.) 
Step-by-step explanation:
f(-2) means plug in -2 in for x for the equation f(x), therefore,
f(-2) = 
Step-by-step explanation:
The point A(2, 4) is
rotated 270 ccw, so the A' should be on the 4th quadrant
=> A' (4, -2)
Answer: 4( x - 5)( x - 2)
Step-by-step explanation:
4x^2 -28x + 40
4 ( x - 5)(x - 2)
90+ 38 +x = 180
128 +x = 180
X= 52, y= 137
Hope this helps!
Answer:
12-9x
Step-by-step explanation:
Here, we want to write an algebraic expression from the given statement
Let us start with the product of 9 and a number x
What this mean is that we want to multiply 9 and x
That gives 9 * x = 9x
Now, 12 is decreased by this product means we are to subtract 12 from it
we have this finally as;
12-9x
