Answer:
x = -4
Step-by-step explanation:
1/4(x - 12) = -4
Multiply both sides of the equation by 4
x - 12 = -16
Move the constant to the right-hand side and change its sign
x = -16 + 12
Calculate the sum
x = -4

Answer:
D = -3, -2, -1, 1, 4
R = -2, -1, -1, 0, 2
It is a FUNCTION
Step-by-step explanation:
Let's assume 1 grid = 1 unit.
The points on the graph has the following coordinates.
(-3, 2), (-2, -2), (-1, -1), (1, -1), (4, 0)
D = the set of input values/x-values
D = -3, -2, -1, 1, 4
R = the set of output values/y-values
R = -2, -1, -1, 0, 2
✅It is A FUNCTION because each x-value has exactly 1 y-value attached to it.
x-2y=-2
x+2y=6

If we spin the spinner 10 times, what is the best prediction possible for the number of times it will land on yellow or purple? 3 blue,5 yellow, 2 red.
Answer:
Yellow = 5 times and I think you meant blue since there is no purple so blue = 3 times
Step-by-step explanation:
There is ten in all and half of the spaces are yellow, or 50%. Out of ten times, you should land on it about half, or 5. For blue, there are 3 spaces, or 30%. Out of ten times, you should lamd on it about three.

Use the following situation for questions #1-10.
Ashley has two jobs: mowing lawns and babysitting. She earns $10 per hour mowing lawns
(x) and $8 per hour babysitting (y). She wants to earn at least $160 per week.
4. What is the x-intercept for the inequality? Show your work!
Answer:
We have the variables:
x = hours that she mows lawns per week.
y = hours that she babysits per week.
She earns $10 per hour mowing lawns and $8 per hour babysitting.
Then she earns a total of:
x*$10 + y*$8
We also know that she wants to earn at least $160 per week.
Then we have the inequality:
Total weekly earnings ≥ $160
This can be written as:
x*$10 + y*$8 ≥ $160
Now we want to find the x-intercept of the inequality.
The x-intercept is the possible y-values when x = 0 (the x-axis)
Then we just need to set x = 0 and find the possible solutions for y.
0*$10 + y*$8 ≥ $160
y ≥ $160/$8 = 20
y ≥ 20
The x-intercept of the inequality is the set of all the points (0, y) such that:
y ≥ 20

Answer:
x = 3
Step-by-step explanation:
Solution: Shift all alphabets to one side and numbers/fractions to the other side.
Shift 1/4 to the other side, it'll become negative.
5x = 61/4 - 1/4 = 60/4
5x = 60/4
x = 60/4 ÷ 5 = 3
-3x + 3y = 5
-x + y = 3
can someone help me ASAP!!!!
Answer:
this Question Is Not correct
Step-by-step explanation:
because
[tex] - 3x + 3y = 5 \\ - x + y = 3 \\ y = 3 + x \\ - 3x + 3(3 + x) = 5 \\ - 3x + 9 + 3x = 5 \\ - 3x + 3x = 5 - 9 \\ 0 = - 4 \\ you \: see \: it \: is \: not \: correct[/tex]
