Answer:
156 minutes
Step-by-step explanation:
So we need to create an equation to represent how Frank's phone company bills him
- I will denote "y" as the total for his bill
- I will denote "x" as the number of minutes Frank uses
So the phone company charges an $8 monthly fee, so this value remains constant and will be our "y-intercept"
They then charge $0.06 for every minute he talks, this will be our "slope"
Combining everything into an equation, we have: y = 0.06x + 8
Now since we were given Franks phone bill total and want to figure out how many minutes he used, we just need to solve the equation for x and plug in our known y value
- y = 0.06x + 8 → y - 8 = 0.06x →
- Then plugging in our y value we get
Frank used up a total of 156 minutes
Answer:
11
Step-by-step explanation:
If you count the total values
it equals 11
A single stepping stone as you have said is 20 inches sqaure. This means that it has an area of 20.
All you would need to do then is multiply 20 by 30 to get the area of thirty tiles. The result of this would be 600.
If you mean one side of the stepping stone is 20 inches then you would multiply 20 by 20 to get the area of one, since that would be multiplying length times width (the area formula). The area of one would result in 400 and you would then multiply this by the thirty tiles (400 times 30) to get 12000.
Answer:
0
Step-by-step explanation:
Value of x for which the two points are on the line with the given slope (1,-1) and (x,7): undefined is 
.
<u>Step-by-step explanation:</u>
Here we have to Find x so that the two points are on the line with the given slope (1,-1) and (x,7): undefined . Let's find out:
We know that for any two points given as 
slope of line is determined by :
⇒ 
According to question we have two points as 
∴
⇒
⇒ 
But slope is undefined which is only possible when denominator is zero i.e.
⇒ 
⇒
Therefore , Value of x for which the two points are on the line with the given slope (1,-1) and (x,7): undefined is .
