Answer:
x = 1
y = 0
Step-by-step explanation:
You did a great job solving one of the equations for a single variable. You solved for x. But what your paper shows is that...it jind of looks like you were going to substitute the 2y+1 into y. BUT you need to substitute it into x.
-4x + 3y = -4
x = 2y + 1
Fill in 2y + 1 into x in the first equation.
-4(2y+1) + 3y = -4
Now you have an equation in one variable. There are only y's in this equation. Next, distribute.
-8y - 4 + 3y = -4
combine like terms.
-5y - 4 = -4
add 4 to both sides.
-5y = 0
divide by -5
y = 0
It's okay that it cam out to be zero. Its fine!
y=0
Put it back in one of the original equations to find x.
x = 2y + 1
x = 2(0) + 1
x = 1
The solution is
x=1
y=0
You can write this as an ordered pair.
(1,0)
Answer:
The graph shaped like a V
Step-by-step explanation:
To see if a relation is a function, you use the vertical line test. If you can draw a vertical line on the graph that touches 2 or more points, then it is not a function. To get a v shaped graph, you have to use absolute values.
So ive done the math and if you add both mA & mB , mC would equal 10
3x
We need to substitute x with 5 because the question is asking how many squats Carlos has completed if he completed 5.
3 x 5 = 15
Therefore, Carlos completed 15 squats as part of his football workout.
By the way, this question is very simple and basic. I recommend reviewing Algebra for your benefit/
