Answer:
x ≥ 2.
Step-by-step explanation:
10 - 8x ≤ -6
Subtract 10 from both sides:
-8x ≤ -16
-8x ≤ -16/-8
x ≥ 2 (Note when dividing by a negative the sign is flipped).
A, 2^12.
3x - y = 12 can also be written as 3x - 12 = y
The fraction is 8^x / 2^y,
Substitute y = 3x - 12 into fraction,
8^x / 2^[3x - 12]
= 8^x / [(2^3)^x × 2^(-12)]
= 8^x / [(2 × 2 × 2)^x × 2^(-12)]
= 8^x / [8^x × 2^(-12)]
{8^x can be factorised out of numerator and denominator of fraction}
= 1 / 2^(-12)
{When the denominator becomes numerator, the power sign is switched from - to +}
= 2^(12)
Hope this helps! :)

Answer:</h3>
(5/7, 12/7) <- I think you meant to type that. Its the first one
<h3>
Step-by-step explanation:</h3>
Step 1: Substitute y=x+1 in for y in 5x + 2y = 7
5x + 2(x+1) = 7
Step 2: Solve it
5x + 2x + 2 = 7
7x + 2 = 7
- 2 - 2
7x = 5

7 7
x = 5/7
Step 3; Plug x into y=x+1
y = 5/7 + 1
y = 12/7
