Answer:
Step-by-step explanation:
m = 500 - 10d
Answer:
(y^2+3y-28)/(4y^2-15y-4)
Step-by-step explanation:
(4y-1)(y-3)(2y+3)(y+3)(y+7)(y-3)/(2y+3)(y-4)(4y+1)(4y-1)(y-3)(y+3)
= (y+7)(y-3)/(y-4)(4y+1)
= (y^2+3y-28)/(4y^2-15y-4)
The answer is the square root of (12^2 + 5^2), which is 13. You're correct
bearing in mind that standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient

just to point something out, is none of the options, however -x + y = 8, is one, though improper.
If you would like to solve the inequality x - 8 > -3, you can do this using the following steps:
<span>x - 8 > -3
</span>x > -3 + 8
x > 5
The correct result would be x > 5.
