Answer:

40^2 + height^2 = diagonal^2

height^2 = 41^2 - 40^2

height^2 = 1681 -1600

height^2 = 81

height = 9

Given the equation 5 + x - 12 = x- 7.
marusya05 [52]

Answer:

Step-by-step explanation:

5 + x - 12 = x- 7 (Add the 5 and -12 to simplify)

x - 7 = x - 7        (notice its the same on both sides of equal sign. Add 7 to both                    sides)

x = x

solution is all real numbers

Part B

5 - 4 - 12 = -4 - 7

-11 = -11

5 + 0 - 12 = 0 - 7

-7 = -7

5 + 5 - 12 = 5 - 7

-2 = -2

Which set of points lies on the graph of x = -2?
inysia [295]
If you use Desmos it'll give you these points:
  (-2,0)
  (-2,2)
  (-2,-2)
Since it's perfectly straight line, all the points with begin with -2. It's the same for graphs like y=-2, which would make them all end in -2. Hope this helped!

What is the answer ?
Mashcka [7]
Hi there! The answer is A.
f(x) = - 2 {x}^{2}

In the graph we can see is a parabola (so B. cannot be the answer) with a vertex at the point (0, 0), which means the parabola is not translated upwards or downwards. Therefore, only A. can be correct, since all the other formulas include a translation downwards (which can be deduced from the -2 in the formula).
