The function is defined as

This means that, taken an input m, the output is the input squared, plus 7.
So, if we take the input -4, we square it to get 16, and we add 7 to get 23.
Answer:
54 cm
Step-by-step explanation:
Using the formula for the area of a trapezoid (area is the sum of the two bases times the height and then halved):
A = 1/2 (h) (b1 + b2)
5350 = 1/2 (h) (135 + 65)
5350 = 1/2 (h) (200)
5350 = h (100)
5350/100 = h
h = 53.5
h ≈ 54 cm
Answer:
x = 10°
Step-by-step explanation:
ZA + ZB = 90°
50° + 4x = 90°
4x = 90° - 50°
4x = 40°
x = 10°
D is the correct answer to your question
Answer:
y = x+6
Step-by-step explanation:
You can find an equation by using the 2-point form of the equation for a line:
y = (y2 -y1)/(x2 -x1)·(x -x1) +y1
Filling in the given values, we have ...
y = (9 -5)/(3 -(-1))·(x -(-1)) +5
y = (4/4)(x +1) +5 . . . . simplifying a bit
y = x +6
