Answer:
y = x +
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 3, - 2) and (x₂, y₂ ) = (5, 4) ← 2 points on the line
m = = = , thus
y = x + c ← is the partial equation of the line
To find c substitute either of the 2 points into the partial equation
Using (5, 4), then
4 = + c ⇒ c = 4 - =
y = x + ← equation of line
The answer would be D.
Since you get a 5% discount you only have to pay 95% of the regular price hence the .95(....
<h2>
Answer:</h2>
The repair took:
2 hours and 45 minutes.
<h2>
Step-by-step explanation:</h2>
The worker charges $54 for the first hour, and $15.50 for each additional 15 minutes.
Let he does a job of additional 15 minutes for: x times.
This means that:
Cost for additional minutes will be: $ 15.50x
Hence, his total cost will be equal to: 54+15.50x
i.e.
54+15.50x=162.50
i.e.
15.50x=162.50-54
i.e.
15.50x=108.50
i.e.
x=108.50/15.50
x=7
Hence, the work took a total of:
60+15×7=165 minutes
which is: 2 hours and 45 minutes.
Answer:
i would say closer to 15.1
Step-by-step explanation:
Subtraction , you would subtract on both sides to get the variable by itself
