Answer:
(2, - 2 )
Step-by-step explanation:
y = - 3 +
x → (1)
3x + 2y = 2 → (2)
Substitute y = - 3 +
x into (2)
3x + 2(- 3 +
x) = 2 ← distribute parenthesis and simplify left side
3x - 6 + x = 2
4x - 6 = 2 ( add 6 to both sides )
4x = 8 ( divide both sides by 4 )
x = 2
Substitute x = 2 into (1)
y = - 3 +
(2) = - 3 + 1 = - 2
solution is (2, - 2 )
#1 is three feet
#2 is 400 feet and #4 a is 2 cm sq. And b is 2.5 cm sq.
Her estimate is not reasonable.
Since she estimated 69%, you could do either of these options. You could...
A. Divide 242 (or .5) to show how much half off would be, then compare her estimate with half of 242 (121). OR...
B. Simply divide 242 by 69% (.69) and compaor her estimate to the exact amount (166.98).
I hope this helps!
