Answer: 30 minutes so 1/2 hour
Step-by-step explanation:
Because 3 miles = 1 hour
1.5 times 2 = 3
divide 2 on both sides
Answer: It looks like Part B is about 4 times that of part A.
Step-by-step explanation: I think the answer would be 12.
A would be 3. B would be 12.
I'm terribly sorry if it is wrong.
Answer:
15
Step-by-step explanation:
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
