Answer:
x= -3
Step-by-step explanation:
1) subtract 15 on both sides
should look like: -6x=18
2) divide the -6 on both sides
3) 18 divided by -6 is -3
Another neighbor said, “My age is the difference between twice my age in 5 years and and twice my age 5 years ago.” How old is this neighbor? A third neighbor had the same claim for 17 years from now and 17 years ago. How old is this neighbor?
Answer:
The neighbor is 20 years old.
The third neighbor is 68 years old.
Step-by-step explanation:
Equations
Let's set:
x=current age of the neighbor
x+5=his age in 5 years
x-5=his age 5 years ago
He claims that his age is the difference between twice his age in 5 years and twice his age 5 years ago. Then:
x = 2( x + 5 ) - 2( x - 5 )
Operating:
x = 2x + 10 - 2x +10
Simplifying:
x = 20
The neighbor is 20 years old.
Repeating for the other neighbor, a similar equation is established:
x = 2( x + 17 ) - 2( x - 17 )
Operating:
x = 2x + 34 - 2x +34
Simplifying:
x = 68
The third neighbor is 68 years old.
-8 + k = -17
What is k to make this equation true
Answer: The answer is k= -9
Step-by-step explanation:
this is how you solve it :
-8+k=-17
so then you add 8 to both sides so it would look like
-8+k+8=-17+8
then you simplify
after you simplify it would equal k=-9

The given table of values represents a linear equation. What is the slope?
A. 4
B. 5
C. 3
D. 6
Answer:
C. 3
Step-by-step explanation:
Formula for slope is given as [tex] m = {y_2 - y_1}{x_2 - x_1} [/tex]
The coordinates of any two points can be used in this formula. Let's use, (1, 5) and (2, 8).
Let,
[tex] (1, 5) = (x_1, y_1) [/tex]
[tex] (2, 8) = (x_2, y_2) [/tex]
Plug the values into the formula:
[tex] m = {8 - 5}{2 - 1} [/tex]
[tex] m = {3}{1} [/tex]
[tex] m = 3 [/tex]

3x-2y=-7
2x+5y+=8
Answer: 3x-2y=-7= Slope = 3.000/2.000 = 1.500
x-intercept = -7/3 = -2.33333
y-intercept = 7/2 = 3.50000
2x+5y+=8
Slope = -0.800/2.000 = -0.400
x-intercept = 8/2 = 4
y-intercept = 8/5 = 1.60000

On average, Ethan drinks 3/4 of an 10 ounce glass of water in 2 minutes how many glasses of water does he drink in one hour
Answer:
22.5 glasses of water
Step-by-step explanation:
Because 3/4 of 10 is 7.5 and if he drinks that every 2 min you have to multiple 7.5 by 30 because 60/2 is 30 which is the amount of min in an hour. when you multiple, you get 225. you have to divide that many oz by 10 because that is how many oz are in a glass and you get 22.5 glasses.

Suppose you have $75 in your savings account and you save an additional $5 each week. Your friend has $30 in his savings account and saves an additional $10
per week. In how many weeks will you have the same amount of money?
Answer:
9 weeks
Step-by-step explanation:
5x+75=10x+30
-5x -5x
75=5x+30
-30 -30
45=5x
÷5 ÷5
9=x
x=9
it will take 9 weeks for you and your friend to have the same amount of money in your savings accounts.
To determine the number of weeks it takes for both you and your friend to have the same amount of money in your savings accounts, we need to set up an equation.
Let's denote the number of weeks as 'x'. For you, the amount of money in your savings account after 'x' weeks can be calculated as follows:
Amount of money in your account = $75 + $5x
For your friend, the amount of money in his savings account after 'x' weeks can be calculated as:
Amount of money in your friend's account = $30 + $10x
To find the number of weeks where you both have the same amount of money, we set up the equation:
$75 + $5x = $30 + $10x
Simplifying the equation:
$5x - $10x = $30 - $75
-$5x = -$45
Dividing both sides of the equation by -5 gives us:
x = 9
Therefore, it will take 9 weeks for you and your friend to have the same amount of money in your savings accounts.

Answer:
$1.80, $2.90, $4.00, $10.90
Step-by-step explanation:
For 9/10 mile, the price will be $1.80. For 2 miles, the price will be $2.90. For 3 1/10 miles, the price will be $4.00, and for 10 miles, the price will be $10.90. The relationship between distance travelled and the price is not proportional because it costs $1.00 for the first 1/10 mile and then for every additional 1/10 mile, it only costs $0.10.

B.
It is the graph of f(x) reflected about the x-axis and stretched vertically by a factor of 8.
C.

Answer:
OTHER GUY IS WRONG!!!
Given that,
Each statement describes a transformation of the graph of f(x) = x.
We have to determine,
Which statement correctly describes the graph of g(x) if g(x) = -8f(x)?
According to the question,
Let, The graph f(x) = x,
Where r is the real number which is r >0.
And The graph of g(x) if g(x) = -8f(x),
The value of the r is -8.
The graph which describes the transformation of the given graph in the steps follows all the steps given below.
The function g(x) = 8f(x) reflects stretched the graph of f(x) vertically by a factor of r.The function g(x) = -8f(x) reflects the graph of f(x) about the x-axis and stretched the graph of f(x) vertically by a factor of r.The graph of g(x) = f(8x) shrink the graph of f(x) horizontally by a factor of r.The function g(x) = f(-8x) shrink the graph of f(x) about the y-axis and shrink the graph of f(x) horizontally by a factor of r.Hence, The graph of f(x) reflected about the x-axis and stretched vertically by a factor of 8.
