Answer:
The value of expression remains the same
Step-by-step explanation:
Let the given function be f(y), where
[tex]f(y) = \frac{3y}{2y}[/tex]
Lets put different values of y to finds its effect on the function
f(y) = 3y/2y
Let y = 1
f(1) = 3(1)/2(1) = 3/2
Let y = 2
f(2) = 3(2)/2(2) = 6/4 = 3/2
Let y = 3
f(3) = 3(3)/2(3) = 9/6 = 3/2
Let y = 10
f(4) = 3(10)/2(10) = 30/20 = 3/2
As we can see, no matter whatever value of y we put in the expression, the result is always the same i,e 3/2
Hence,
The value of expression remains the same
An electrician uses the function f(x) = 60 + 40x to calculate the total cost, in dollars, for a service call that takes x hours to
complete. What does the coefficient 40 represent?
A)
The electrician works 40 hours.
B)
The electrician charges $40 per hour.
Eliminate
The electrician drives 40 miles to work.
D)
The electrician charges a $40 trip charge.
Answer:
(B) The electrician charges $40 per hour.
Step-by-step explanation:
Total cost=fixed cost + variable cost
F(x)=60+40x
Fixed cost =60
Variable cost=40x
x=hours of service
40=40 dollar per hour charge
The coefficient 40 represent the electrician charge of $40 per hour
(B) The electrician charges $40 per hour.

Answer:
14- yes
15-No
16-11.5
Step-by-step explanation:
14- yes ( attached a picture) 5/6
15-no, because Direct Variation: It is known as the relationship between two variables where the variable quantities have a constant ratio.
8y=7x-27
y=7/8 x-27/8
16- ky=x where k is the constant variation
k=166/83=2
ky=x when x=23
y=x/k=23/2=11.5
Calculate the mean and median of: 202, 199, 223, 199, 223, 256, 301, 199
a. mean = 199, median= 212.5
b. mean = 225.25, median = 199
c. mean = 225.25, median = 212.5
d. mean = 212.5, median = 225.25
Answer:
C. mean =225.25, median= 212.5
Step-by-step explanation:
You add all the numbers and divided by the total numbers to get mean, and for get the median you need to put them in order and get the number that is between all the number it be the 202 and 223 so you divide the two number with two and it will be 212.5
Answer:
C. mean =225.25, median= 212.5

which equation is represented by the graph below
Answer:
C). y = ln x + 4
Step-by-step explanation:
First off, we can cancel out the [tex]e^{x}[/tex] graphs.
Now looking at the graph, one can see that when x = 1, y = 4.
So for each [tex]ln[/tex] function, plug in 1 for x.
In doing this, one will find that y = ln x + 4 is the only [tex]ln[/tex] graph that produces 4 when x = 1.

Answer:
45 + c = 110
c = 65
Step-by-step explanation:
110 - 45 = 65
Please mark as brainliest!

If f = {(2,5), (3, 2) (4, 6), (5, 1), (2, 2)), then f is a function.
Answer:
false
Step-by-step explanation:
f is not a function because you can see that two of the points are (2,5) and (2,2). A function can only have one corresponding y-coordinate for every x-coordinate and since this is not the case here, f is not a function.

Answer:
A
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here b = 13 and h = 4 , thus
A = [tex]\frac{1}{2}[/tex] × 13 × 4 = [tex]\frac{1}{2}[/tex] × 52 = 26 units² → A
Answer:
A, 26
Step-by-step explanation:
Since the area of a triangle is one half base times height, and we have our height as 4, and our base as 13, we get 1/2 * 13 * 4, which is equal to 13 times 2, which is 26. Thus, our answer is A, 26.

Step-by-step explanation:
Levi would like to use a credit card to make a $3000 purchase. He is considering two credit options. The first requires a down payment of $1000 followed by monthly payments of $125. The second requires a down payment of $1300 followed by monthly payments of $110. The two options accumulate the same amount of interest and require the same number of monthly payments. What is the amount of interest for this loan?
Answer: $500
Step-by-step explanation:
Hi, since both credit options accumulate the same amount of interest:
1000+125x=1300+110x
Solving for x(number of months)
125x-110x =1300-1000
15x = 300
x =300/15
x= 20 months
Replacing x =25 in one equation:
1000+125x =
1000+125(20)=
1000+2500= $3500
Finally, we have to subtract the amount of the purchase (3000) to the result obtained:
3500-3000=$500

Solve for x in the triangle. Round your answer to the nearest tenth.
Answer:
8.5
Step-by-step explanation:
For this we will use trigonometry.
First lable the diagram: 13 will be the hypotenuse (H), x will be the opposite(O). Therefore, we will use sin as it is SOH.
sin Θ = [tex]\frac{O}{H}[/tex]
sin 41 = [tex]\frac{x}{13}[/tex]
x = 13 sin 41
Type this into the calculator, then you will get 8.5287677377. Round this to the nearest tenth will be 8.5.
As the question does not give any units, there will be no need to write any units after the answer.
Hope this helps
Answer: 8.53
Step-by-step explanation:
Calculated based on 2 given angles and 1 given side.
∠C = 180° - A - B = 49°
x = hypoteneuse·sin(A)/sin(B) = 8.53
Solve for x in the triangle. Round your answer to the nearest tenth.
Answer:
x ≈ 6.9

Answer:
x=35
Step-by-step explanation:
Since a quadrilateral's interior angles add up to 360°, we get this:
360-85-20=360-4x+x
340-85=360-3x
255=360-3x
-105= -3x
Multiply both sides by -1
105=3x
3x=105
Divide both sides by 3
x=35
