Answer: you
Step-by-step explanation: look it up
You do that dilation by multiplying every x- and y-coordinate value by 2.5.
Answer:
k=-3
x=63
Step-by-step explanation:
The equation for direct variation is
y = kx where k is the constant of variation
We know x and y we can solve for k
-87 = k*29
Divide each side by 29
-87/29 = k
-3 =k
y= -3x
Now we know y = -189, we can find x
-189 = -3x
Divide by -3
-189/-3 = -3x/-3
63 =x
Answer:
y = (2x + 3)(2x + 3) = (2x + 3)²
Step-by-step explanation:
We are given a quadratic function and we have to write it in factored form.
y = 9 + 12x + 4x²
y = 4x² + 12x + 9
We can break the mid-term in such a way that when they are multiplied, the factors give a product of 36x² and when added, they give a result of 12x, as show below:
y = 4x² + 6x + 6x + 9
Taking 2x common from the first two variables and 3 from the second two
y = 2x(2x + 3) + 3(2x + 3)
Taking 2x+3 common
y = (2x + 3)(2x + 3) = (2x + 3)²
