Answer:
(-6, 6), (2, 6), (-6, -2), (2, -2)
Step-by-step explanation:
Unfortunately, you can't just multiply the coordinates of the corners by 4. That works if the center of the enlargement is the origin, (0, 0). So you have to do this enlargement in 3 steps for <u>each</u> of the corner points.
Step 1 Move the point right 2 units and down 2 units
<em>.</em>
The reason for this step is that this is what you do to move the center (-2, 2) to (0, 0).
Step 2 Multiply the new coordinates by 4.
Step 3 Move the new point left 2 units and up 2 units
.
Example: using the upper-left corner (-3, 3)...
Step 1 
Step 2 
Step 3 
Repeat the process with the other three corners.
Answer:
x = 6
Step-by-step explanation:
Take f(x) = -(x+9)(x-21) and multiply it out. We get:
f(x) = -[x^2 + 9x - 21x - 189], or
f(x) = -x^2 + 12x + 189
This is a quadratic equation. The coefficients are a = -1, b = 12 and c = 189.
The equation of the axis of symmetry is x = -b/(2a), which here equals:
x = -12 / [2*(-1)], or x = 6.
Answer:
B
Step-by-step explanation:
Communitive only works with multiplication and addition. It states that if you have something adding or subtracting something switched around, they are the same. B has that so the answer is B
