Answer: 113.1ft²
Step-by-step explanation:
The answer is 113.1ft²
One way to write a linear equation is the formula y = mx + b where m is the slope of the function and b is the y-intercept. For this reason, it is known as slope-intercept form.
The slope os calculated via the formula . Lets calculate the slope of the equation first.
So the slope is -0.12. This means for every minute of time used, $0.12 of credit is used. Next, lets plug in the value for m, and the values of an x and y point to find b.
y = 0.12x + b
23.16 = -0.12(57) + b
23.16 = -6.84 + b
30 = b
So, our final equation is y = -0.12x + 30.
Finally, we can use this equation to find the answer to the last part by plugging the value into x.
y = -0.12(60) + 30
y = -7.2 + 30
y = 22.8
So when 60 minutes have been used, there will be $22.80 worth of credit left.

Answer
The statement is false
Step-by-step explanation:
When you convert either side to either a decimal or a fraction they end up equal. This means in order for the statement to be true it would have had to say greater than or equal to the other number or vice versa.
Answer:
y = -x + 3
Step-by-step explanation:
I graphed the equation on the graph below to show you that it goes through (-1,4) and is perpendicular to y = x.
