Answer:Find out the expressions for the number of sweets sue and tony have now .
To proof
As given
Sue has 18 sweets. tony has 18 sweets.sue gives tony x sweets
thus
sue sweets = 18 - x
Tony sweets = 18 + x
As given
Sue then eats 5 sweets. Tony then eats half of his sweets
sue sweets becomes = 18 -5 -x
= 13 - x
Hence proved
Step-by-step explanation:
B- 18 units to the left of zero
Answer:
3
Step-by-step explanation:
y = 3 - 1/2x
rewrite equation so the slope is in front
y = -1/2x + 3
plug in 0 for x
y = -1/2(0) + 3
solve for y
y = 0 + 3
y = 3
y- intercept = (0,3)
