Since both sides of the equation are equal, x has infinite solutions.
Diana is comparing the membership costs at two fitness centers. The community fitness center costs $60 per month. The fitness center located where she works has a $100 registration fee and costs $40 per month. After how many months of membership will the costs be the same?
2
3
4
5
Answer:
5 months
Step-by-step explanation:
Make the question into an equation where the cost of one gym equal to the cost for the other.
60x = 100 + 40x
x represents how many months
20x = 100
x = 5
It would take 5 months of membership for the costs to be the same.
The answer is 5 months.
How to make a linear equation?The linear equation is made using the constraints given in the question, examining whether the data is added, subtracted, divided, or multiplied.
How to solve a linear equation?To solve the linear equation we group the variable on the LHS and then equate it with the constant and this is done by transposing, or using an arithmetic operator on both sides.
The solution to the given problemLet the number of months taken be 'x'
SO the community fitness takes 60x money for x months
The fitness center where she works takes an amount of 100+40x for x months as registration fees are only charged once.
so equating the equation to find the value of x.
100+40x = 60x
Transposing 40x from LHS to RHS
100=60x-40x
20x = 100
Dividing the equation by 20 on both sides
x = 5
The membership costs will equal in 5 months.

For what value(s) of k will the given relation not be a function?
M = { (15k+9, 4), (3·(4k−1), 6) }
Enter all possible values of k
Given:
The relation is
[tex]M = \{ (15k+9, 4), (3\cdot (4k-1), 6) \}[/tex]
To find:
The value of k for which the relation is not a function.
Solution:
A relation is a function if their exist a unique output or y value for each input or x values.
A relation is not a function if it has two y-values for single x value.
So, the given relation is not a function if x-coordinates of both ordered pairs are equal.
[tex]15k+9=3\cdot (4k-1)[/tex]
[tex]15k+9=12k-3[/tex]
Isolate variable terms.
[tex]15k-12k=-9-3[/tex]
[tex]3k=-12[/tex]
Divide both sides by 3.
[tex]k=-4[/tex]
Therefore, the given relation is not a function for k=-4.

select all input values for which g(x)=8
choose all that apply
a)x=-4
b)x=6
c)x=9
d) none of the above
picture of graph:
Answer:
a. x = -4
c. x = 9
Step-by-step explanation:
Values of g(x), output values, are plotted on the y-axis, while the corresponding x values, input, of the function are plotted on the x-axis.
We are to determine all possible input values (x-values) that will give us an output value, g(x) = 8.
On the graph, look at the point where y = 8, on the y-axis. When y = 8, we have two possible values of x. They are -4, and 9.
Thus:
g(-4) = 8
g(9) = 8.
The possible input values for which g(x) = 8, are x = -4, and x = 9.

Question: After watching some fish 40 feet below the surface of the water, a scuba diver went up 15 feet to explore a coral reef. Use a number line to help you create an equation that shows the location of the coral reef in relation to the water surface.
Answer:
C. -40+15 = -25
Step-by-step explanation:
The diver went down 40 feet underneath the surface, so that would be -40. When the diver went up 15 feet, that would be adding -40 to 15. So, the diver would be going closer to the surface after coming up 15 feet. -40+15 = -25

Alina is 6 years older than Greg. Amy’s age is 2.5 times Alina's age. Amy is 40. How old is Greg?
A. 16
B.10
C. 15
D.10
Answer:
Hi friend! The answer is D. 10
I hope this helps!
Answer:
B) 10
Step-by-step explanation:
Assign variables to each person:
A=Alina's Age
M=Amy's Age
G=Greg's Age
Set up a system of equations given the information:
A=6+G
M=2.5A
M=40
Notice that M is already given, so we can plug that into the second equation:
40=2.5A
16=A
So Alina is 16 years old, but the problem asks for Greg's age, so we plug Alina's age in the first equation:
16=6+G
10=G
So Greg is 10 years old, therefore B is the correct answer.
llene is making bows for gift wrapping. She uses 1 feet of ribbon for each 3 bow. How much ribbon will she need to make 12 bows?
Answer:
4 feet
Step-by-step explanation:
Because if she used 1 feet of ribbon for 3 bows you need to multiply by 4 to 1 foot and you will get 12 bows
Answer:
4 feet of ribbon
Step-by-step explanation:
Because she uses 1 feet of ribbon for each 3 bows, we can create a fraction.
1 ft / 3 bows = x ft / 12 bows
Cross multiplying, we get: 3x = 12
Divide by 3 and we get x = 4 (x in this case is in feet)

help! SOS! due by tonight midnight
Answer:
A. x=35
B. C= 59 degrees
Step-by-step explanation:
Since both angles have the same measurement you set them equal to each other as so & solve for x
3x+16=5x-54
16=2x-54
70=2x
x=35
Now we plug 35 into one of the equations
3(35) + 16
105+ 16 = 121 degrees
Since angle C is a supplementary angles you do 180-121= 59 degrees
solve 4x-3 = 2x+7.
Answer:
x=5
Step-by-step explanation:
4x-3 = 2x+7.
Subtract 2x from each side
4x-2x-3 = 2x-2x+7.
2x-3 = 7
Add 3 to each side
2x-3+3 = 7+3
2x= 10
Divide by 2
2x/2 = 10/2
x = 5
Answer:
x=5
Step-by-step explanation:
4x -3 = 2x +7
Let's start by getting the 2x away from the seven. Subtract the 2x from itself and from 4x. We will subtract 2 because a negative will cancel out the positive.
2x -3 = +7
Now let's get the -3 away from 2x. Add 3 to the -3 and the +7. We will add because a positive will cancel out the negative.
2x = +10
Then divide +10 by 2 to get the final answer.
