7x - 12 = 9x - 26
+12 +12
7x = 9x - 14
7x = 9x - 14

PLEASE HELP ILL MAKE BRAINLIEST!!!!!
Answer:
The first one because every x value can only have one y value
Step-by-step explanation:
The set of ordered pairs that represents y as a function of x are; {(0, 0), (1, 1), (2, 3), (3, 3)}
We must be aware that, dependent variable, y can only be a function of x if;
For every value of x, there must only be one value of y.
In essence,
For case 1:
y is a function of x, because for every value of x, there's only one value of y.For Case 2:
y is not a function of x, because there's two values of y for a value of x.For Case 3:
y is not a function of x, because there's two values of y for a value of x.For Case 4:
y is not a function of x, because there's two values of y for a value of x.Read more:

6. Talayah bought two journals. The second
journal cost $12 more than the price of
the first journal. If she spent $30 on both,
how much was the second journal?
A. $12
B. $16
C. $20
D. $28
Answer:
C. $20
Step-by-step explanation:
Lets make our equation. "x" will be our first journal, and "4/5x + 12" will be our second journal. So our equation is: x + 4/5x + 12 = 30
Subtract 12 from each side: x + 4/5x = 18
Combine like terms : 1 4/5 x = 18
Divide each side by 1 4/5 : x = 10
Plug in x for the journals-
1 = 10
2 = 4/5 of 10 = 8 + 12 = $20

The vertices of a triangle are, A (2, 5) B (1, 2) C (3, 1),. Find the coordinates of the image after a
reflection in the x-axis, and then a rotation 90° counterclockwise about the origin.
Answer:
The images are;
A’ (5,2) B’ (2,1) and C’ (1,3)
Step-by-step explanation:
Firstly, we want to reflect across the x-axis
When we reflect a point (x,y) over x-axis, we get (x,-y)
So;
A ( 2,5) becomes (2,-5)
B (1,2) becomes (1,-2)
C ( 3,1) becomes (3,-1)
Then we proceed to rotate 90 degrees counterclockwise about the origin
Here we have;
(x,y) becomes (-y,x)
(2,-5) becomes (5,2)
(1,-2) becomes (2,1)
(3,-1) becomes (1,3)
Answer:
A’ (5,2) B’ (2,1) and C’ (1,3)

Jamie's father has to build a corral for her new pony. The plan shows the length of the sides of the corral. Jamie's father says that the fence posts must be ten feet apart
Answer:
16
Step-by-step explanation:
The post must be 10 feet apart, the width of the corral is 50 feet and the length is 30 feet.
Each width sides get 6 posts and the length get 2 posts each.
therefore the total number of posts needed for the corral is;
= perimeter of a rectangle
= 2 ( l + w) / 10 feet apart
= 2 ( 50 + 30) / 10
= 160/10
= 16 posts

The perimeter of a 6-sided figure is 67.74 meters. Two of the sides have the same length. The sum of the other 4 side lengths is 36.4 meters. About how long is each of the same-side lengths?
Each of the same-side lengths is 15.67.
What is perimeter?It is the sum of length of the sides used to made the given figure.
We have been given that the perimeter of a 6-sided figure is 67.74 meters. Two of the sides have the same length. And the sum of the other 4 side lengths is 36.4 meters.
Let the same side be a.
The perimeter of the figure = 6 x side
The perimeter of the figure = 2a + 36.4
67.74 = 2a + 36.4
2a = 67.74 - 36.4
2a = 31.34
a =15.67
Therefore, each of the same-side lengths is 15.67.

Answer: 125

She surveryed 80 people out of the 400 in her school. 80 x 5 = 400 so 25 (the people who like pop music) times 5 will equal 125, the amount of people in her school that like pop music.
The cost of a gym membership is $25 per month. There is an initial fee of $40
Answer:
y = 25x + 40
Step-by-step explanation:
Using the formula, y = mx + b we can find out what this equation would be.
m = the rate of change/slope
b = the y- intercept
25 per month is telling us that this is the rate of change.
Since the $40 is only paid once, you can tell that this is the y intercept.
The equation will look like:
y = 25x + 40
On a graph it would look like:
Let the total cost of a gym membership be y, with the number of months as x.
The total cost would be 40 dollars, the initial fee, plus 25 times the number of months (x).
y = 40 + 25x

7.) x-3>4 please help
Answer:
x>7
Step-by-step explanation:
x-3>4
Add 3 to both sides
x>7
Hope it helped!
Answer:
x>7
Step-by-step explanation:
To solve the inequality you need to isolate the variable. To do so add 3 to both sides of the equation, x-3+3>4+3, which simplifies to x>7. This means any number greater than but not equivalent to 7 is a solution. So 8 or 100 would work but 7, 2, or -2 would not.
