Answer:
d=3
Step-by-step explanation:
so yu do 18+18 and yu get 36 and then you do 43+3 vause that is how muvk the lockers cost
Answer:
$2
Step-by-step explanation:
Fees = $18
Locker fee =$d
Total cost for 2 people,including locker for 2 people
=$40
2($18 + d) = $40
$36 +2d = $40
2d = $4
d = $2
if you want to check
Fees for one people =$18
Two people =$18 × 2 = $36
Total cost for 2 people - locker for 2 people = $40 - $ 2($2) = $40 - $4 = $36

Line g has an equation of y=-3/2x – 8. Line w, which is parallel to line g, includes the
point (4, -3). What is the equation of line w?
Answer:
y = -3/2x + 3
Step-by-step explanation:
If two lines are parallel to each other the slopes are the same.
So line w's slope would be the same as line g's -3/2
Now all we have to do is pug in the points to find the y-intercept.
-3 = -3/2(4) + b (b represents the y-intercepts)
-3 = -6 + b (add 6 on both sides)
3 = b
y = -3/2x + 3 is the equation for w.
Solve for x.
32 – 8 < 23
OR
4x + 26 > 6
Answer:
32-8< 23
24< 23
4x + 26>6
4X +26> 6 + 26 move the constant to the right
4x =32 divide both sides by 4
x= 8

f (x) = cx + 3
In the function above, c is a constant. If f (1) = 1, what is the value of f (-4) ?
If f(1) = 1 that means c is -2 because when you substitute x = 1 and when c = -2, you'll get f(1) = -2(1)+3 = -2+3 = 1
So the constant c is -2 and that means the value of f(-4) is
f(-4)=-2(-4)+3=8+3=11
Thus, the value of f(-4) is 11.
About why does "c" have to be -2, here's the proof.
Given y = f(x), therefore.
y=cx+3
Since when x = 1 and y = 1, then Substitute x = 1 and y = 1, thus 1 = c+3
1 - 3 = c and therefore, -2 = c #
So this is the proof that c = -2

A bike shop has 11 1111 red bikes, 3 33 blue bikes, 4 44 orange bikes, and 12 1212 silver bikes. For every 1 11 orange bike, there are 3 33 _ _ _ _ _ _ _ _ _ _________\_, \_, \_, \_, \_, \_, \_, \_, \_. Choose 1 answer: Choose 1 answer: (Choice A) A Red bikes (Choice B) B Blue bikes (Choice C) C Silver bikes
Answer:
C. Silver bikes
Step-by-step explanation:
Given that:
Number of red bikes at the bike shop = 11
Number of blue bikes at the bike shop = 3
Number of orange bikes at the bike shop = 4
Number of silver bikes at the bike shop = 12
Let us find the ratio of each bike with orange bikes to find the answer.
Orange bikes: Red bikes = 4 : 11
i.e. for every 4 orange bikes, there are 11 red bikes.
Orange bikes: Blue bikes = 4 : 3
i.e. for every 4 orange bikes, there are 3 blue bikes.
Orange bikes: Silver bikes = 4 : 12 = 1 : 3
i.e. for every 1 orange bike, there are 3 silver bikes.
Therefore, the answer is:
C Silver bikes

13. If I || m, find the values of x and y.
(7x+12)
(12x-28)
(9y - 77)
Answer:
x=8 y=21
Step-by-step explanation:
7x+12=12x-28
x=8
plug in x
12x8-21=68
68+9y-77=180
y=21
The values of [x] and [y] will be 8 and 21 respectively.
What does the term " l || m " represents?This term indicates that the line 'l' is parallel to the line 'm'.
Given is the image and the measurement of angles.
It can be seen in the figure that, ∠(7x + 12) and ∠(12x - 28) from alternate interior angles as line 'l' and 'm' are parallel. These angles will be equal to each other. Therefore, we can write -
7x + 12 = 12x - 28
12x - 7x = 12 + 28
5x = 40
x = 8
Now, ∠(12x - 28) and ∠(9y - 77) form a straight angle. Therefore, we can write -
(12x - 28) + (9y - 77) = 180
(12 x 8 - 28) + (9y - 77) = 180
68 + 9y - 77 = 180
9y = 180 + 9
9y = 189
y = 21
Therefore, the values of [x] and [y] will be 8 and 21 respectively.

True or false? The graph represents a function
Answer:
False. This is not a function.
Step-by-step explanation:
By using the vertical line test, it shows that this graph is not a function. The imaginary vertical line would go through the graph twice. To be a function, the imaginary vertical line can only go through once.

1. Felicia wants to know the gas milgage of her new car. She starts recording how much gasoline
she puts into the car, and how many miles she travels before the warning light comes on and
she need to add more gas. A table of her data is shown below.
Gas (gallons)
1 4 8 10
Miles
19 84 160 203 218
a. Consider miles M as a function of gallon and use data points to find a linear function
to model the data.
b. Consider gallons G as a function of miles M and use data points to find a linear function
to model the data.
C. How do the functions of (a) and (b) compare? Are they both useful models?
d. What could be some reasons why the points do not fit perfectly with your equation?
Step-by-step explanation:
(a) If M is a function of G (M is the y-axis and G is the x-axis), then the linear function is approximately:
M = 20G
(b) If G is a function of M (G is the y-axis and M is the x-axis), then the linear function is approximately:
G = M / 20
(c) The two functions are inverse of each other. The first function tells us how many miles she can drive with a certain number of gallons. The second function tells us how many gallons she needs to drive a certain number of miles.
(d) There are multiple things that affect fuel mileage. These include:
Speed - idling at a red light or driving at high speeds will lower your mileage.
Weather - high winds will lower your mileage.
Weight - adding weight (even the weight of the gas itself) will lower your mileage.
Tires - low pressure in the tires will lower your mileage.
The given table is an illustration of a linear scatter plot, where:
[tex]M = 19.9G -0.9[/tex].[tex]G = \frac{10}{199}M + \frac{9}{199}[/tex].M and G are both inverse functions(a) M as a function of G
From the table, we have the following points:
[tex](G_1,M_1) = (1,19)[/tex]
[tex](G_2,M_2) = (11,218)[/tex]
Calculate the slope (m)
[tex]m = \frac{M_2 - M_1}{G_2 - G_1}[/tex]
[tex]m = \frac{218-19}{11-1}[/tex]
[tex]m = \frac{199}{10}[/tex]
[tex]m = 19.9[/tex]
The equation is then calculated using the following linear equation formula:
[tex]M = m(G - G_1) + M_1[/tex]
[tex]M = 19.9(G - 1) + 19[/tex]
[tex]M = 19.9G - 19.9 + 19[/tex]
[tex]M = 19.9G -0.9[/tex]
(b) G as a function of M
From the table, we have the following points:
[tex](M_1,G_1) = (19,1)[/tex]
[tex](M_2,G_2) = (218,11)[/tex]
Calculate the slope (m)
[tex]m = \frac{G_2 - G_1}{M_2 - M_1}[/tex]
[tex]m = \frac{11-1}{218-19}[/tex]
[tex]m = \frac{10}{199}[/tex]
The equation is then calculated as follows:
[tex]G = m(M - M_1) + G_1[/tex]
[tex]G = \frac{1}{19.9}(M - 19) + 1[/tex]
[tex]G = \frac{1}{19.9}M - \frac{19}{19.9} + 1[/tex]
[tex]G = \frac{1}{19.9}M - \frac{19-19.9}{19.9}[/tex]
[tex]G = \frac{1}{19.9}M - \frac{-0.9}{19.9}[/tex]
[tex]G = \frac{1}{19.9}M + \frac{0.9}{19.9}[/tex]
[tex]G = \frac{10}{199}M + \frac{9}{199}[/tex]
(c) How (a) and (b) compares
Functions (a) and (b) are both inverse functions of one another;
Because they both represent inverse functions, both are useful models
(d) Reasons points do not fit in the equation
Some reasons why the points do not fit are:
Short tripsVehicle break downSpeedHeavy breaksWhen any of these happens, the mileage will be affected because she won't be able to capture the accurate data by the time she continues her trip.
