The answer is (1) x=-2. The property of the equation like y=ax2+bx+c is that the axis of symmetry of the graph is x=-b/2a. So for this question, the axis is x=-4/2=-2.
D) $20 because if you plug it in to the equation it equals $225
Answer:
50,0
Step-by-step explanation:
So we know 500×100=50,000
So it's 50,000
Answer:
They are 10 units away from the treasure
Step-by-step explanation:
Notice that the points (9, -7) and (9, 3) are both located at the same x-value (9) while their y-values are in one case 3 units above the x-axis, and in the other 7 units BELOW the x-axis. Therefore thy differ by 3 - (-7) units , which totals 10 units.
a) Given:
To simplify:
Applying zero power rule,
So, we get
Hence, the answer is 1.
