Answer:
<h2><u><em>
y = 3</em></u></h2>
Step-by-step explanation:
2 over 6 = Y over 9 Fraction equation is required
2/6 = y/9
y = 2/6 * 9
y = 3
check
2/6 = 3/9
1/3 = 1/3
the answer is good
9514 1404 393
Answer:
6
Step-by-step explanation:
Cost and revenue are equal when ...
C = R

X = 0 ; y = 10 ; 10 = a(0) + b(0) + c
c = 10
x=2 ; y = 15 ; 15 = a(4) + b(2) + 10 ; 5 = 4a+2b
x=4 ; y=18 ; 18 = a(16) + b(4) + 10 ; 8 = 16a + 4b
2(5) = (4a+2b)2
-
<u> 8 = 16a + 4b
</u> 2 = -8a
a = -0.25
b = 2
y = (1/4)x^2 + 2x + 10 ; 4y = x^2 + 8x + 40
