Mathematics
1 answer:
Olegator [25]3 years ago
4 0

Answer:

The answer to your question is f(x) = \sqrt{x+ 4}

Step-by-step explanation:

                                           f(x) = x² - 4

Process

1.- Change f(x) for y

                                           y = x² - 4

2.- Change "x" for "y" and "y" for "x".

                                           x = y² - 4

3.- Make "y" the object of the equation

                                          y² = x + 4

                                          y = \sqrt{x+ 4}

4.- Change "y" for f(x)

                                          f(x) = \sqrt{x+ 4}

Mr. Robinson has 20 students in his martial arts class. The ratio of boys to girls is 4:1. How many boys and girls are in Mr. Ro
svlad2 [7]
1) Ratio - 4:1

thus, 4x + 1x = 20
5x = 20

thus, x = 20/5 = 4

thus, x = 4
and, 4x = 16

Thus, the answer is (C) 16 boys and 4 girls

2) According to distributivity, a(b+c) = ab + ac

Thus, the answer is (C)

The time, t, required to drive a certain distance varies inversely with the speed, r, if it takes 7 hours to drive the distance
user100 [1]
Inverse functions will be given by the following equation:

t * r = k

k is a constant value that the two variables must multiply to.

Plug in your t and r values:

7 * 55 = 385

k = 385.

Now we'll have to find a value that multiplies with 65 to equal 365.

Set up the following equation:

x * 65 = 385

This equation can also be treated as the following:

65x = 385

Divide both sides by 385 to get x by itself:

x = 5.92

The answer is C. about 5.92 hrs to drive the same distance of 385 miles.

How do I simplify 6y-y
aniked [119]
Think of 6y as

y + y + y + y + y + y

Now subtract a y from that.

y + y + y + y + y + y - y = y + y + y + y + y = 5y
