Answer:
x = -7
Step-by-step explanation:
-1 + x = -8
x = -7
Use two pints on the graph to find the slope:
(0,0) and (5,1)
Slope = Change in Y over the change in x.
Slope = (1-0) / (5-0) = 1/5 = 0.20
The slope of the given equation is 0.25 which is greater than 0.20.
The unit rate is greater in the equation.
Answer:
Option 3 - 
Step-by-step explanation:
Given : Perpendicular to the line 
; containing the point (4,4).
To Find : An equation for the line with the given properties ?
Solution :
We know that,
When two lines are perpendicular then slope of one equation is negative reciprocal of another equation.
Slope of the equation
Converting into slope form 
,
Where m is the slope.
The slope of the equation is 
The slope of the perpendicular equation is 
The required slope is 
The required equation is 
Substitute point (x,y)=(4,4)
Substitute back in equation,
Therefore, The required equation for the line is
So, Option 3 is correct.
Top right
this is because, when dividing an inequality by a negative number, you must flip the inequality sign
-3x < 21
x > -7
Answer:
Step-by-step explanation:
Figuring out based on $10.00 per hour rental fee.
you would take the number of full hours and multiply by the fee.
5 hours x $10 = $50
for the leftover .5 hours (which is half an hour) you would take the $10 hourly fee and divide it in half.
$10 ÷ 2 = $5 per half hour
$5 x 1 (half hour) = $5
Now add up the total for the 5 hours and the total for the half hour and that is your total cost.
