Answer: x = 3
y = -1
There are many ways to do the systems of equations. To solve this, I used the substitution method.
Isolate y or x (whichever is easier) in the first equation IF NECESSARY.
y = x - 4 --> it's already given
Substitute in (x - 4) for y in the second equation.
2x + (x - 4) = 5 Distributive Property
2x + x - 4 = 5 Combine like terms
3x - 4 = 5 Add 4 to both sides
3x = 9 Divide by 3 to both sides
x = 3 Answer!
Substitute in (3) for x in the first equation.
y = (3) - 4 Simplify
y = -1 Answer!
Answer:
f(x) =x
Step-by-step explanation:
f(x) = -3x+2
This is a line so the parent function must be a line
That eliminates a which is a cubic function and d which is a absolute value functions
[x] means greatest integer which is not what the type of graph we are making
The parent function is x

Answer
5 miles
Step-by-step explanation:
If he rides his bike one mile each day school to home each day its going to be 1 mile per day so if its 5 days it is 5 miles
Answer:
x = 5.2
Step-by-step explanation:
Let's first simplify our first function:
Now, we just need to set this function equal to our other given function.
Now, we can add 12 to both sides:
Now, add 5x to both sides:
Finally, we'll divide both sides by 5:
Answer: x = 5.2
