Answer:
4) J
5) D
Step-by-step explanation:
4) 416 = 2x² - 6x
2x² - 6x - 416 = 0
x² - 3x - 208 = 0
x² - 16x + 13x - 208 = 0
x(x - 16) + 13(x - 16) = 0
(x - 16)(x + 13) = 0
x = 16, -13(not possible)
So 16 rows
5) y = a(x - h)² + k
y = a(x - 3)² - 7
When x = 1, y = -10
-10 = a (1 - 3)² - 7
-10 = 4a - 7
4a = -3
a = -¾
y = -¾(x - 3)² - 7
Step-by-step explanation:
but that is the easiest of all 4 questions (by far) :
3g(x) + h(x) = 3×(5x² + 3) + 9x² = 15x² + 9 + 9x² = 24x² + 9
which is exactly f(x) = 24x² + 9
so, yes, they are equal.
I really have to wonder, since you correctly solved 1-3, what was the issue with 4. ?
Please include the following items
Answer:
y=0.75x+3.75
Step-by-step explanation:
The slope is
Substituting into point-slope form,
y - 6 = 0.75(x - 3)
y - 6 = 0.75x - 2.25
y = 0.75x + 3.75
Answer:
1/3 feet.
Step-by-step explanation:
The length = area / width
= 7/9 / 2 1/3
= 7/9 / 7/3
= 7/9 * 3/7
= 3/9
= 1/3 feet,
