Answer:
$0.06 per square inch
Step-by-step explanation:
The question should be:
<em>"If tile costs $8.50 per square foot, how much does it cost per square inch?"</em>
<em />
To solve this, we basically need a conversion from feet to inches. BUT 2 times, since we are talking about "square feet" and "square inches".
We know 1 feet = 12 inches
Also, since we are going from square feet to square inches [big to small], we have to divide TWICE.
Thus, we will have:
We are dividing 8.5 (the cost) by 12, 2 times since we want square feet in square inches. The answer is:
So, tile costs $0.06 per square inch
Answer:
The last one at the right
Step-by-step explanation:
It is a function because not of the x axis numbers are repeated.
Answer and explanation
a is $18.00 because Z is a constant
b is y=2.50x+18.00
c is that y=2.50x+z turns into y=$55.50 and then x=15 which we substitute
that leads to 55.50 =2.50(15)+z
and the untimely z = 18.00 dollars .

Step-by-step explanation:
<u>Step 1: Define</u>
g(x) = x³ - 4
h(x) = x² + 2
h(-2) is x = -2
g(-1) is x = -1
<u>Step 2: Find h(-2) - g(-1)</u>
- Substitute: ((-2)² + 2) - ((-1)³ - 4)
- Exponents: (4 + 2) - (-1 - 4)
- Add/Subtract: 6 - (-5)
- Subtract: 11
