Answer:

Domain: (-∞, ∞), Range: [-3, ∞)

Step-by-step explanation:

Domain is all of the possible x-values in a solution set, in this case since the solution extends infinitely horizontally it would be:

(-∞, ∞)

The range is just all of the possible y-values in a solution set, which in this set starts from -3 and proceeds on infinitely, making the range:

[-3, ∞)

The average size of a certain computer datafile is 255 kilobytes. 10 million of these datafiles can be stored in a harddisk.
mr_godi [17]

Answer:

Hi! Your answer here is 2550 GB. To find this answer, we multiply 255 (the number of kb) by 10,000,000 (the number of files.) This gives us 2,550,000,000 KB. There are 1,000,000 kb in 1 GB, so we divide 2,550,000,000 by 1,000,000, which gives us 2550. 2550 GB of files can be stored.

Given the image of the right triangle below, choosing angle A as the reference angle, label which of the three sides of the tria
alina1380 [7]

Answer:

c is the hypotenuse

a is the leg opposite

b is the leg adjacent

Step-by-step explanation:

The hypotenuse is the line across the right angle

Since we have angle A, a is the one across, so it is the opposite

B is the adjacent one.

The rectangle below has an area of 70 square meters.
nasty-shy [4]

Answer:

The side lengths are 10 by 7

Step-by-step explanation:

The area of a rectangle is

A = l*w

70 = (x - 11)(x - 8)

FOIL

70 = x^2 -8x-11x+88

Combine like terms

70 = x^2 -19x +88

Subtract 70 from each side

0 = x^2 -19x +88-70

0 = x^2 -19x+18

Factor

What number multiplies to 18 and adds to -19

-18*-1 =18

-18-1 = -19

0=(x-18)(x-1)

Using the zero product property

x-18=0   x-1=0

x=18   x=1

But x cannot x=1 because then the side lengths would be negative

x-18 = 10

x-11 = 7

The side lengths are 10 by 7
