Reflection over the y-axis is like a mirror image across the vertical axis. It is equidistant from the y axis on the other side and the x coordinate stays the same.
So, your new point is the fourth choice, (4, -2).
Answer:
35, 39, 44, 52, 55, 57, 60, 69
Step-by-step explanation:
Composite numbers have multiple factors other than 1 and itself.
Answer: 24
Step-by-step explanation:
Answer is 9.
-3x^2 + 243 = 0
Bring 243 to the right.
-3x^2 = -243
Divide by -3.
x^2 = 243/3 = 81
Tak the square root of both sides.
x = 81^1/2 = 9.
If (x+5) is a factor the equation will equal zero when x=-5 so
3(-5^2)+14(-5)+k=0
75-70+k=0
5+k=0
k=-5
