Answer: B
Step-by-step explanation:
Every real is solution of the equation .
When you write URGENT the Brainly cops think you may be taking a test.
y = ax² + c thru (-1,4) and (0,8)
Substituting in the coordinates of each point for x and y gives two equations:
4 = a (-1)² + c
8 = a (0²) + c = c
From the second one we see c=8. Substituting into the first one,
4= a + 8
a = 4-8 = -4
Answer: a=-4, c=8
Check:
f(x) = -4x² + 8
f(0) = 8, good
f(-1) = -4(1) + 8 = 4, good
Answer:
Find 6.75% of 260
Step-by-step explanation:
Hi
Answer:
I think the answer would be C
Step-by-step explanation:
Since the square root of 64 is 8, 8 has an absolute value, so it can be opposites as it, eg. 8 = -8.
