Answer:
your answer is for sure D but I think C is also the answer
Step-by-step explanation:
Additive relationship are two quantities can be expressed as related to each other through addition. It can be written as y = x + a, where y is related to x through the addition of a constant, a. The value for a may be positive or negative.
Roxanna earns $18 per hour.
If Roxanna earns $72 in 4 hours, then the equation to find how much she earns per hour is:
72/4 = x
x = 18

If there was a number other than 0 before the decimal point, it would serve as the whole number in our final answer.
First count the number of digits after the decimal point. For this problem it's 4.
Then make the denominator 10 raised to the power of your answer in the first step so the denominator for this question is 10⁴=10000
The numerator will be the number after the decimal point.
The fraction will be = 112/10000
Then reduce it to the lowest term
If you divide the numerator and denominator by 16 you get
7/625 which is the lowest possible fractional term.
Answer:
Step-by-step explanation:
in a right triangle a^2+b^2=c^2,
where a and b are the legs
where c is the hypothenuse
9^2= b^2+3^2
81-9=b^2
b^2=72
b=8.48
Answer:
y = 8x + 15
Step-by-step explanation:
Step 1: Find slope of perpendicular line
<em>Take the negative reciprocal of the 1st equation</em>
m = 8
y = 8x + b
Step 2: Find <em>b</em>
7 = 8(-1) + b
7 = -8 + b
b = 15
Step 3: Rewrite perpendicular equation
y = 8x + 15
