Answer:
The rate of sales tax is 6%.
Step-by-step explanation:
First you must subtract 12.50 from 13.25
This brings you to .75
Then, divide .75/12.50 to get 0.06 which is equivalent to 6 percent.
Equation of required line is:

Step-by-step explanation:
First of all we will convert both equations in slope-intercept form

Subtracting 5x from both sides

Subtracting 9 from both sides

The y-intercept is -9.
Other equation is:

Adding 3x on both sides

Dividing both sides by 4

As the required line has y-ntercept of line y + 5x + 9 = 0
So,
b = -9
And
The line is parallel to second line, so the slopes of both will be equal

Slope-intercept form of line is:

Putting values of b and m

The ordered pair that is not on the graph is (-4,46)
Answer:
x = 18 y = 5
Step-by-step explanation:
x + 5 = 2x - 13
x - 2x = -13 - 5
-x = -18
x = 18
2y - 2 = 4y - 12
2y - 4y = -12 + 2
-2y = -10|:(-2)
y = 5
Answer:
Line A
Step-by-step explanation:
Hello!
Given that the x-values is the time in minutes, and the y-axis is the number of dishes stacked, for every minute, the line should go up by 7.
This means, that the value of y when x is 1 should be 7. The line that follows this rule is Line A. For every minute, 7 dishes are stacked.
The answer is Line A.
