Answer:

n = 20

Step-by-step explanation:

Add 7n to both sides.

-5n + 7n - 12 = 2n - 12.

-7n + 7n + 28 = 28.

Now the equation is 2n - 12 = 28.

Add 12 to both sides to isolate the variable.

2n - 12 + 12 = 2n.

28 + 12 = 40.

Now the equation is 2n = 40. Divide both sides by 2.

n = 20.

A line has a slope of 9/4 and a y-intercept of -14.
scoray [572]
The answer correct is C.

We can use the linear equation y=mx+b to help. y is the dependent variable, m is slope, x is the independent variable, and b is the y intercept.

In this case, the values of x and y were not given, so we still have y=mx+b. We can substitute 9/4 for m and -14 for b to get y=9/4x-15, which is C.

25 points to anybody who can solve this pls!
Svetach [21]

Answer:

Q' (2,4)

R' (3,1)

S' (5,3)

Step-by-step explanation:

When reflected across x-axis, the x-values stay the same but y-values change signs. Because you count how many points till the reflection line then same amount you have to go to the other side. But since it is saying x-axis, the reflection line is on x=0 so you just change the sign.
