Shortly after creating a car washing business, you made $65 washing ten
cars. Then after fifteen cars, you made $115. Build a model. Write an
explanation for the slope. Write an explanation for the y-intercept. How
many cars have you washed if you have made $255?
Answers
Answer:
A) For the slope;
Rate of change in profit per change in number of cars washed = 10
B) when he had not washed any car, he was in debt of of $35
C) When he made $255, he had washed 29 cars
Step-by-step explanation:
Slope intercept equation of a line is;
y = mx + c
you made $65 washing ten
cars. Thus, x = 10 and y = 65
So, 65 = 10m + c - - - - (eq 1)
Then after fifteen cars, you made $115.
Thus, x = 15 and y = 115
So; 115 = 15m + c - - - - (eq 2)
Subtract equation 1 from eq(2) to get;
115 - 65 = 15m - 10m + c - c
50 = 5m
m = 50/5
m = 10
Putting 10 for m in eq 1 gives;
65 = 10(10) + c
65 = 100 + c
c = 65 - 100
c = -35
A) Since the slope is m = 10 and slope is m = Δy/Δx, it means that;
Rate of change in profit per change in number of cars washed = 10
B) c = -35 is the y-intercept.
This means when x = 0, y = - 35.
It implies that when he had not washed any car, he was in debt of of $35
C) since we have the slope and intercept, equation is;
y = 10x - 35
If he has made $255,then we have;
255 = 10x - 35
255 + 35 = 10x
290 = 10x
x = 290/10
x = 29 cars washed.

1.8 + 3.5y + 0.9 + 9 = 16.2
Answers
Answer:
Its about 1.3
Step-by-step explanation:
3.5y=16.2-1.8-0.9-9
3.5y=16.2-11.7
3.5y=4.5
Divide through by 3.5 to get y
3.5y/3.5=4.5/3.5
y=1.2857
Guests at a Beaumont hotel stay for an average of 9 days with a standard deviation of 2.4 days. Assume that the length of stay is normally distributed. Assume that we select randomly 1000 guests. How many of those guests can be expected to stay between 7 and 14 days
Answers
Answer:
778
Step-by-step explanation:
We have the length of stay as X
X~N (9,(2.4))
The sample is given as n = 1000
P(7<x<14) is what we are trying to get
P(7-9/2.4 < x-9/2.4 < 14-9/2.4)
= P(-0.83<z<2.08)
P(z<2.08)-p(z<-0.83)
When we go to the z table,
0.981-0.0203
= 0.778
0.778x1000
= 778
So in conclusion, 778 of these guests can be expected to stay between 7 and 14 days.

3.25(1.25x + 0.5) = 10.5 ................ given
4.0625x + 1.625 = 10.5 ................ distributive property
4.0625x = 8.875 ................ subtraction property of equality
x = 2.18461538461539 ....... division property of equality
---------------------------
Notes:
The decimal value of x is approximate. Round it however you need.In the third step, we subtracted 1.625 from both sidesIn the fourth step, we divide both sides by 4.0625Answer:
I am pretty sure that is right
Step-by-step explanation:
[tex]3.25(1.25+0.5) = 10.5[/tex] is given
Then you distribute the [tex]3.25\\[/tex] to the [tex]1.25x[/tex] and the [tex]0.5[/tex].
[tex]3.25(1.25x)=4.06x[/tex]
[tex]3.25(0.5)=1.6[/tex]
So the new equation would be [tex]4.06x + 1.6= 10.5[/tex]
Then you would subtract [tex]1.6[/tex] from each side to get [tex]4.06x=8.9[/tex]
Finally you would divide each side by [tex]4.06[/tex] to get [tex]x= 1.93[/tex].

Answers
Answer:
x=.5
Step-by-step explanation:
First, you need to isolate the variable term, so you have to move -5 over to the other side. Since it is subtraction on this side, you add 5 to both sides to cancel out the -5, and add it to the other side.
Now we have 10x=5. To solve for the variable, we have to divide by the number in the variable term. In this case, it is 10. 10/10 is 1, so now x is alone. We have to do the same thing on the other side. 5/10 is .5.
That's the answer! It's x=.5!
