Answer:
a. $1000
b. 100
c. 900
d. 1017
Step-by-step explanation:
a.
marked price = 800×1.25=1000
b.
discount amount
1000×0.9=900
1000-900=100
c.
1000×0.9=900
d.
900×1.13=1017
Answer:
9) -25/21
11) 14
Step-by-step explanation:
In each case, subtract the y-coordinates. Subtract the x-coordinates in the same order. Divide the difference in y by the difference in x.
9)
y-coordinates: -10 - 15 = -25
x-coordinates = 6 - (-15) = 21
slope = (difference in y)/(difference in x) = -25/21
11)
y-coordinates: -20 - 8 = -28
x-coordinates = 3 - 5 = -2
slope = (difference in y)/(difference in x) = -28/(-2) = 14
I took this today and I got 16ft since this is A^2+B^2= C^2 but I’m not sure but for now I got 16
A) The more gas you buy, the more it costs.
Answer:
21.43 miles
Step-by-step explanation:
Let
x ---> the number of miles
y ---> the total cost of rent a car per day
we know that
The linear equation in slope intercept form is equal to

where
m is the slope
b is the y-intercept
we have
<em>sunshine rental company</em>
The slope is equal to

The y-intercept is equal to

substitute
----> equation A
<em> rent me company</em>
The slope is equal to

The y-intercept is equal to

substitute
----> equation B
equate equation A and equation B

solve for x
