Answer:
-1/2
Step-by-step explanation:
Answer:
x = 2 1/4 y = -1/2
Step-by-step explanation:
y= - 1/2
y=2x-5
Substitute y = -1/2 into the second equation
-1/2=2x-5
Add 5 to each side
5-1/2 = 2x-5+5
4 1/2 = 2x
Multiply each side by 1/2 to isolate x
9/2 *1/2 = 2x * 1/2
9/4 = x
Change to a mixed number
2 1/4 =x
If by function form you're referencing a y= equation then this is how you do it.
You want the y variable to be alone on its own side, so our first step is to subtract that ugly 5x from the left side.
That gives you -y=-5x-1
Now, we never want the y to be negative so we fix this by multiplying both sides by negative one which will cancel out that negative.
We are then left with y=5x+1
Add the two fractions together but first rewrite the fractions with a common denominator.
4/15 = 8/30
3/10 = 9/30
8/30 + 9/30 = 17/30
Answer: 17/30
