Answer :x=-3
Step-by-step explanation:Solve for x by simplifying bothh sides of the equation then isoolating the variable
Answer:
(3,6)
Step-by-step explanation:
2x-3y = -12
x+y=9. Solve for either y or x
-x. -x
y = -x + 9. Substitute this for the y
2x-3(-x+9)= -12
2x +3x-27 = -12. Add like terms
5x -27 = -12
+27. +27. Inverse operations
5x = 15
÷5. ÷5
x = 3
x + y = 9
3 + y = 9. Substitute 3 for x
-3. -3. Inverse operations
y = 6

80 feet; (use Pythagorean Theorem: leg^2 + leg^2 = hyp^2 )
Answer:
B. y² – 5y = 750
C. 750 – y(y – 5) = 0
E. (y + 25)(y – 30) = 0
I'm assuming the 2 in the second option is supposed to be an exponent.
Step-by-step explanation:
Length = y
Width = y-5
Length × Width = Area
Area = <u>y(y-5)</u> = 750
<u>Distribute.</u>
y²-5y=750 (B is correct)
<u>If you factor the equation above</u>
(y + 25)(y – 30) = 0 (E is correct)
Area = y(y-5) = 750
<u>Subtract y(y-5) from both sides.</u>
750-y(y-5) = 0 (C is correct)
