Answer:
Step 2: 20x = 80 + 10x
Step-by-step explanation:
Step 1: 20x - 10 = 80 + 10x
Add 10 to each side
20x - 10+10 = 80+10 + 10x
20x = 90 + 10x
Step 2: 20x = 80 + 10x This has the first error
Step 3: 10x = 80
Step 4: x= 8
The identity property of addition states that the sum of any number and 0 is the original number.
so...x + 0 = x would be the identity property of addition (also called the additive identity)
Answer:
The slope is 8 and the y intercept is 0
Step-by-step explanation:
The equation is written in slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = 8x+0
The slope is 8 and the y intercept is 0
