Answer:
25/8
Step-by-step explanation:
Given That:
R = 8x+4y
X= 8
R = 30.
So, 8 x 8 +4y = 30
Simplify, Rearrange and solve.
64 + 4y = 30
4y = 30/64 = 15/32
y = 15/32 divided by 4
y = 15 / 32 x 1/4
y = 15/(32 x 4) = 15/128
hope this helps

Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = -x² - 2x + 2
f(x + 3) is x = x + 3
<u>Step 2: Find</u>
- Substitute in <em>x</em>: f(x + 3) = -(x + 3)² - 2(x + 3) + 2
- Expand: f(x + 3) = -(x² + 6x + 9) - 2x - 6 + 2
- Distribute -1: f(x + 3) = -x² - 6x - 9 - 2x - 6 + 2
- Combine like terms: f(x + 3) = -x² - 8x - 13
320,000 / 3,840 = 730,000 / x
cross multiply because this is a proportion
(320,000)(x) = (3,840)(730,000)
320,000x = 2,803,200,000
x = 2,803,200,000 / 320,000
x = 8760 <====
