Answer:
1
Step-by-step explanation:
In the ordered pair (2, 12), x = 2 and y = 12.
Substitute these values into each inequality to see if the resulting inequality is true.
y > 2x + 4
12 > 2(2) + 4 Twelve is greater than 2 times 2 plus 4 ...hmmm
12 > 4 + 4
12 > 8 Twelve is greater than 8 ....this is TRUE...go to the next inequality
y < 3x + 7
12 < 3(2) + 7 Twelve is less than 3 times 2 plus 7 ...interesting
12 < 6 + 7
12 < 13 Twelve is less than 13 ... this is TRUE also
Therefore; the answer is b. Yes
It must create a true inequality for BOTH inequalities in order for the ordered pair to be a solution
Answer:
d and c
Step-by-step explanation:
Statement 1 is false because the domain of f is all real numbers since the function is quadratic.
Statement 2 is true<span>.
Statement 3 is true because when we graph f, it is a parabola opening upwards with vertex (3, -1). Since it is opening upward, then the value of x from -</span>∞ to 3 is decreasing while increasing from 3 to ∞.
<span>
Statement 4 is false because we just stated above that f is decreasing from -</span>∞ to 3. Hence, f is also decreasing from -1 to 3. Hence, f is not increasing from -1 to <span>∞.
</span><span>Statement 5 is false because the axis of symmetry is x = 3.
Statement 6 is true.</span>
