Let's assume the temperature was 10.
it increased 25% so this is the equation for it:
10 +25%=12.5 degree.
then it decreased 40%
so it will be as follow:
12.5 degree - 40%= 7.5 degrees.
Answer:
5 miles per hour
Step-by-step explanation:
Anna runs 6 1/4 miles in 1 1/4hours. What is her rate in miles per hour?
6 1/4 miles / 1 1/4 hours =
25/4 miles / 5/4 hours =
5 mph or miles per hour or miles/hour
Answer:
Your answer is D
Step-by-step explanation:
Evaporation happens when a liquid substance becomes a gas. When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor.

Answer:
- (5, 9)
- (5, 6)
- (-5,-6)
- (5, -9)
- (-9, -5)
Step-by-step explanation:
Compare the given functions to the vertex form. Match parts to find the values of h and k. The vertex is (h, k).
Vertex form: f(x) = a(x -h)^2 +k
__
f(x) = 5(x - 5)^2 + 9; h = 5, k = 9; vertex: (5, 9)
f(x) = 9(x - 5)^2 + 6; h = 5, k = 6; vertex: (5, 6)
f(x) = 9(x + 5)^2 - 6; h = -5, k = -6; vertex: (-5, -6)
f(x) = 6(x – 5)^2 - 9; h = 5, k = -9; vertex: (5, -9)
f(x) = 6(x + 9)^2 - 5; h = -9, k = -5; vertex: (-9, -5)
Answer:
x=4
Step-by-step explanation:
EF is half of the top and bottom lines comined so you would make an equation:
5x+8/2=2x+6
5x+8=4x+12
x=4
