Answer:
92 miles
Write an inequality for the total cost of the rental.
Cost of the rental = 19.50+0.25x<=44
where x is the number of miles driven.
Subtract 19.50 from both sides.
0.25x<=44-19.50
0.25x<=24.5
x<=24.5/0.25
x<=98
Step-by-step explanation:
Answer:
Step-by-step explanation:
(-7, 8) (-8, 8)
(y2 - y1) / (x2 - x1)
(8 - 8) / (-8 + 7)
0 / -1
the slope is 0
you could also see this because the y value doesn't change
if the y value doesn't change the slope is 0, if the x value doesn't change the slope is undefined
Answer:
Complex roots
Step-by-step explanation:
Given
Required
The type of solution
Rewrite as:
To determine the type of solution, we simply calculate the discriminant (D)
Where
So, we have:
The above value implies that:
When , the solution of the equation is: complex roots
The sum of tax and discount will given by:
(15+7.25)%
=22.25%
Total percentage of the total cost will be:
100+22.25%=122.25%
the selling price of the court will be:
122.25/100×275
=4336.187
The answer is 4336.20
Answer:Think of the equation as an equation for a line
y=mx+b
where in this case
C= 5 /9 (F−32)
or
C= 5 /9 F - 5/9 x 32
You can see the slope of the graph is 5 /9
, which means that for an increase of 1 degree Fahrenheit, the increase is
5 /9 of 1 degree Celsius.
C= 5 /9 (F)
C= 5/9(1)
C=5/9
Therefore, statement I is true. This is the equivalent to saying that an increase of 1 degree Celsius is equal to an increase of
9/5 degrees Fahrenheit.
C= 5/ 9 (F)
1= 5 /9 (F)
(F)= 9 /5
Since
9/5 = 1.8, statement II is true.
The only answer that has both statement I and statement II as true is D, but if you have time and want to be absolutely thorough, you can also check to see if statement III (an increase of 5/9 degree Fahrenheit is equal to a temperature increase of 1 degree Celsius) is true:
C= 5 /9 (F)
C= 5 /9 x 5/9
C=25/81
(which is≠1)
An increase of 5/9
degree Fahrenheit leads to an increase of
25/81.
, not 1 degree, Celsius, and so Statement III is not true.
The final answer is D.
