0.7777... repeats and does not end so it is irrational
F(x) = 9x²<span> - 5x + 2
</span>f(-2) = 9(-2)² - 5(-2) + 2
<span>f(-2) = 36 + 10 + 2
</span><span>f(-2) = 48</span>
Any decimal can be a fraction

Answer:
2.0
Step-by-step explanation:
Subtract the smaller number from the larger to find their difference:
1.5 -(-0.5) = 2.0
The distance between the given values is 2.0.
Answer:
C
Step-by-step explanation:
thee equation they give us is 2x + 18 = 32. Our goal is to isolate x.
First, subtract 18 from both sides to eliminate it.
2x + 18 = 32 ---> 2x + 18 - 18 = 32 - 18 ----> 2x = 14
Next, separate the 2 from the x by dividing it from both sides:
2x = 14 ----> 2x/2 = 14/2 ----> x = 7
By solving this equation, we find that x, or one sandwich, costs $7.
