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:
10x^2 - 4x
Step-by-step explanation:
5x - 2 times 2x will equal the area of 'Potatoes.'
5x times 2x is 10x^2.
2 times 2x is 4x.
I cannot provide an exact value because x hasn't been identified.
I hope this helps.
The answer to this question is 8 for $6
Answer:
Step-by-step explanation:
The line in between the numerator and denominator serves as a division sign so, -7 divided by 18 equals -0.38 with the 8 repeating
Is it the absolute value? If so then 1.
