Answer:
13pounds =$7
13/7pounds = $1
1.85pounds=$1
Step-by-step explanation:
It is b. 48 because f(x) is 3
The answer is 24 multiplied by 10 to the power of 4
First, we write the first equation where the left side contains x and y in the right side. We do as follows:
x = 2y + 6
You, then substitute the equation to the second one.
3(2y + 6) + y = 8
6y + 18 + y = 8
7y = -10
y = -10/7
x = 22/7
Answer:
Slope: 1
Y-intercept: (0,3)
Step-by-step explanation:
The y intercept is when the slope reaches the y-axis line. In this case, it is given to us. Anything that is formed like this: (0, y) is the y-intercept.
Y intercept: (0, 3)
For slope, you can use the formula rise over run. 
From the picture, I have drawn the rise over run, which is
, which is also 1.
Slope: 1
