Answer:
Step-by-step explanation:
The quantity x + 7 is squared.
Expand the brackets and simplify the expression.
We can leave the expression in factored form.
The x-intercept is found by solving the equation for y=0. Doing that, we get ...
0 = x+1 . . . . .put 0 where y is in the equation
-1 = x . . . . . . subtract 1 from both sides
Then the x-intercept is ...
(x, y) = (-1, 0) . . . . . . corresponds to the second selection
First, let's solve the inequality:
Subtracting 4 from all 3 terms, we get -6 < 3x < -2
Solving -6 < 3x results in x>-2, and solving 3x < -2 results in x < -2/3.
Ask: which integers satisfy x>-2? Answers: -1, 0, 1, 2, ....
Also ask: which integers satisfy x < -2/3? Answers: -5, -4, -3, -2, -1
Notice that the only integer that is found in both sets of possibilities is -1. So, only one integer x satisfies the given inequality.
