We substitute the given into the equation
given: a=-1, b=2, c=

=(

=

-1
to continue, we can either find a common denominator or change the fraction to decimal.
Fraction to Decimal:

=-2.5
Equation=-2.5-1=-3.5
OR Common Denominator:
=


×

(denominator should be -2=common)
=

+

=

which also = to -3.5
Answer:
156ft would be the answer
Step-by-step explanation:
Simple, 184-28=156. If it was the area you would divide 184 by 28 to get about 6.57.
L+W=P
aka length + width= perimeter. But LxW=Area, LxW=A, or bXh (base times the height)
Hey!
Find 80% of the original cost:
1.25 * 80% = 1
1.25 + 1 = 2.25
ANSWER: $2.25.
To find the slope, we put this in y = mx + b form where m is ur slope.
3x - 4y = 7.....subtract 3x from both sides
-4y = -3x + 7 ...now we divide both sides by -4
(-4/-4)y = (-3/-4)x + (-7/4)...simplify
y = 3/4x - 7/4
y = mx + b
y = 3/4x - 7/4.....so the number in the m position is 3/4 <== ur slope
