First divide both sides of the inequality by 3.
On the left, the 3's cancel and you're left with j
and on the right, 6 divided by 3 is 2.
So we have j >2 which is the solution to this inequality.
I have graphed the inequality for you below.
Start with an open dot on 2.
We use an open dot because j > 2 but it is not equal to 2.
Then draw an arrow to the left to
represent all numbers greater than 2.
Answer:
x = -4 or 2
Step-by-step explanation:
-4x² + 10x − 40 = -9x²
First, move the x terms to one side and the constant to the other.
5x² + 10x = 40
Divide by the leading coefficient:
x² + 2x = 8
Take half of the b coefficient, square it, then add to both sides.
(2/2)² = 1
x² + 2x + 1 = 8 + 1
x² + 2x + 1 = 9
Factor the perfect square:
(x + 1)² = 9
Solve for x:
x + 1 = ±3
x = -1 ± 3
x = -4 or 2
I believe the answer is 59 .
first , you plug your variables into the equation : 10(3)(2) - (3) + (2) . next , you multiply the 10 and the 3 and the 2 to get : 60-3+2 . now , you add and subtract from left to right to get : 57+2 . now you add those and get 59 .
hope this helps :)
Answer:
h=37
Step-by-step explanation:
h + 3h + (h-5) =180
5h-5=180
5h=185
divide by 5
