Answer:
4.36
Step-by-step explanation:
dividing the amount of hours by how many miles Adrienne went will give you how many miles she went per hour.

a÷b
a=24
b=5.5 (5 1/2)
24÷5.5=4.36
18 is not a function because a function is when exactly ONE x value is paired with ONE y value.
19 is not a function because of the same logic for number 18
8x-27=3x+58, get all x values on one side and constants on the other 5x=85, now divide both sides by 5. We get the answer of x=17
Answer:
a. square root of 5
b. square root of 13
c. 9
d. 13
Step-by-step explanation:
Q1.
The initial value of the linear relationship is -2 /y-intercept/
Answer: -2.
Q2. /<span>The slope of a
line is a <span>rate of change./</span></span>
x = -1 and y = 10
x = 1 and y = 9
(10 - 9)/(-1 - 1) = -1/2
<span>Answer: A. -1/2.
</span>Q3.
y = 3.50x + 300
<span>Answer: Bobby has $300 in the yearbook fund and earns $13.50 for each yearbook sold.
</span>Q4.
y = mx + b
(0; 10); (2; 20)
m = (20 - 10)/(2 - 0) = 10/2 = 5
(0; 10) ⇒ b = 10
y = 5x + 10
<span>Answer: Shanna had $10 in her piggy bank and earned $5 each week in allowance.
</span>Q5. /<span>The slope of a
line is a <span>rate of change./
</span></span> y = 150x + 1,400
Answer: 150.
