Answer:
-8 ≤ y ≤ 8
Step-by-step explanation:
Subtract 7 from the first one:
y ≥ -8
Subtract 3 from the second one, then multiply by 4.
y/4 ≤ 2
y ≤ 8
Now, you can write these as a compound inequality:
-8 ≤ y ≤ 8

<em>Additional comment</em>
You basically solve these the same way you would an equation. The only difference is that multiplying or dividing by a negative number will reverse the inequality symbol:
2 > 1
-2 < -1 . . . . . multiplied above by -1.
When a zero of a function does not cross the x-axis but touches it, this means that the zero is a "double root". It has two of the same factor (x - 4)^2 and two of the same zeros, x = 4 and x = 4
f(x) = x^2 - 8x + 16 would be the function with a double root at 4
Each year it will gain $10 so it will take 50 years.
1,000 × .02 = 20
1,000 ÷ 20 = 50

Answer:
2.27 miles is the answer.
Step-by-step explanation:
Money needed = $48+$0.52 = $48.52
So,
$48.52 = 1 mile
$1 = 1/$48.52
$110 = (1/$48.52)×$110
= 2.27 miles
