Answer:(0,0) (-5,-5)
Step-by-step explanation:
Answer:
True
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (- 4, - 9), thus
y = a(x + 4)² - 9
To find a substitute the coordinates of the zero (- 7, 0) into the equation.
0 = a(- 7 + 4)² - 9, that is
0 = 9a - 9 ( add 9 to both sides )
9a = 9 ( divide both sides by 9 )
a = 1, thus
y = (x + 4)² - 9 ← expand factor using FOIL
y = x² + 8x + 16 - 9
y = x² + 8x + 7
Answer:
8 pounds is greater than 96 ounces.
Step-by-step explanation:
1 pound=16 ounces
16*8=128
128 is greater than 96

Is the root of 9801</span>
The answer is A! This is because the formula is (x-h)^2 + (y-k)^2 = r^2.
Because there is no value, you can see that h and k are zero. This means that the center, (h,k) is (0,0).
