Answer:
True
Step-by-step explanation:
To solve this type of problem the most efficient method is to take the ordered pair and introduce it into the inequality, if this is satisfied then the point belongs to the inequality, if the point is not satisfied it does not belong to the inequality.
We have the following inequality
Then we introduce the ordered pair into the inequality.
0 is less than -1, therefore the inequality is met and the ordered pair (1.0) is a solution of the inequality
THE affirmation is true
Answer:
8, 10
Step-by-step explanation:
Multiplying the equation by the product of the denominators, we have ...
40(x+2) +40x = 9x(x+2)
80x +80 = 9x^2 +18x . . . . eliminate parentheses
9x^2 -62x -80 = 0 . . . . . . put in standard form
9x^2 -72x +10x -80 = 0 . . . prepare to factor by grouping
9x(x -8) +10(x -8) = 0 . . . . . factor pairs of terms
(9x +10)(x -8) = 0
Solutions are ...
x = -10/9 and x = 8
The integers are 8 and 10.

I find a graphing calculator to be a nice tool for solving these. It finds zeros easily, so writing the equation so it equals zero is a useful first step.
