Step-by-step explanation:
15.50 + 1.50r =26 r =
Answer:
2x²-2x
Step-by-step explanation:
To find the area of a rectangle, you multiply the sides together.
In this case:
x × 2x-2 = x(2x-2) = 2x²-2x
Answer:
12+15=27 total students, each car can seat 4, so 27/4=6.75, you would round up to 7 bc you can't have 3/4ths of a car
Step-by-step explanation:
First, you would have to make the number of hours the x value and total cost the y value in the graph. Then, you would take however many hours to replace x, let’s say 5, and replace it for x in the equation y=8x+12, giving you y=8*5+12. You would then solve it by multiplying 8 and the x value, 5, giving you 40 in this example, and then adding 12, giving you 52 dollars for 5 hours.
To draw the line on the graph, you would start 0 hours with 12 dollars, 1 hour for 20 dollars, 2 hours for 28 dollars, and so on, adding 8 each time you add an hour.
Answer:
Equation in slope-intercept form is
Step-by-step explanation:
We need to write equation in slope-intercept form to represent the relationship shown in the table.
The general equation of slope-intercept form is:
where m is slope and b is y-intercept.
Finding slope using point (-2,-6) and (0,0)
The formula used is:
We have
Putting values and finding slope
Using slope m= 3 and point (-2,-6) we can find y-intercept
So, we have y-intercept b =0
Equation in slope-intercept form having slope m= 3 and y-intercept b =0 is:
So, Equation in slope-intercept form is
