Answer:

Step-by-step explanation:

we can easily find this by looking at our y intercept

our y intercept here is (0, -1) so the equation who has -1 as a constant is the one were looking for

so C would be oour answer since its the only one with -1 as its constant

hope this helps <3

Simplify (x^-2y^6/x^-4y^8)1/2

AlexFokin [52]

Simplify the following:
(y^6 y^8)/((2 x^2)/(x^4))
Combine powers. (y^6 y^8)/((x^2×2)/x^4) = (y^(8 + 6) x^(4 - 2))/2:
(y^(8 + 6) x^(4 - 2))/2
8 + 6 = 14:
(y^14 x^(4 - 2))/2
4 - 2 = 2:
Answer: (y^14 x^2)/2

Answer:

75cm^2

Step-by-step explanation:

When you say a rectangular prism, it means it has the base has 4 sides of which opposite sides are equal as a rectangle. This sides substends so we have a total of 6 surfaces in this prism.

This 6 surfaces has 3 surface area the same.

The surface area = sum of area of all faces.

325= 50 + 50 + 37.5 + 37.5 + 2x; where X is the area of the surface unknown.

325= 100+ 75 + 2x

325-175= 150

150= 2x

X= 150/ 2 = 75 cm^2
