C) 12 degrees
Angle N corresponds to R, and 180-90-78=12, which is the measure of the missing angle.
Answer:
x = -5
Step-by-step explanation:
The equation y = x^2+10x+25 can be factored to (x+5)^2
when (x+5)^2 = 0
x = -5
meaning the equation has a line of symmetry at x = -5
Answer:
It would be D
Step-by-step explanation:
If you do the problem backward and apply the discount and taxes to 20$, then you get 18.70
To determine the new amount you need to find out what 2/3 of 4 1/2 is equal to. What you see "of" in an algebraic expression or equation, replace it with (×).
2/3 of 4 1/2 =
2/3 × 4 1/2 =
Convert 4 1/2 to an improper fraction.
2/3 × 9/2 =
Now multiply and reduce
18/6 = 3
The new amount of dog food is 3 cups.
Answer:
C
Step-by-step explanation:
The rule tells you that (x,y) -> (x + 1, y - 3), so you take each vertice and add one to the x-values, and subract 3 from the y-values.
(-6, 4) -> (-6 + 1, 4 - 3) which simplifies to (-5, 1)
(-3, -2) -> (-3 + 1, -2 - 3) which simplifies to (-2, -5)
(2, 1) -> (2 + 1, 1 - 3) which simplifies to (3, -2)
