Answer:
f(-2)=27
Step-by-step explanation:
Plug in -2 into x
f(-2)=2(-2)^2-8(-2)+3
f(-2)=8+16+3
f(-2)=27
Answer:
A'(-1,-4)
B'(-5,-8)
C'(-5,-4)
D'(-4,-2)
Step-by-step explanation:
We have been given a graph of a quadrilateral and we are asked to find the coordinates of our quadrilateral after reflecting it across the x-axis.
We can see that coordinates of quadrilateral ABCD are:
A (-1,4),
B (-5,8),
C (-5,4),
D (-4,2).
Since we know that rule for reflecting an image across x-axis is . This means that y-coordinates of our given image will be negative.
So after reflecting our given quadrilateral across x-axis, coordinates will be:
Answer:
170.6
Step-by-step explanation:
170.55
The tenths place is where the left 5 is.
1. Drop everything to its right.
170.5
2. Look at the first digit that was dropped. It is a 5. That means the last digit that remains goes up by 1 to 6.
Answer: 170.6
Answer:
a or c because they both are equal to 27

Answer:
<h3>x = 5 or x = (-1)</h3>
Step-by-step explanation:
(x - 5) = 0 or (x + 1) = 0 should be.
x = 5 or x = -1
