What is the domain and range? (Answer needs to use inequalities.)

Answer: x + 8

Step-by-step explanation:

Set up the expression (3x+7) - (2x-1)

Then, distribute the negative sign across the 2x and -1 to get 3x+7-2x+1

Combine like terms: 3x-2x+7+1

= x + 8

Answer:

A.

Answer:5<x<15

Step-by-step explanation:

Answer:

Step-by-step explanation:

0<2x-10<20

If a<u<b then a<u and u<b

0<2x-10 and 2x-10<20

0<2x-10= x>5 2x-10<20 = x<15

Combine the intervals

x>5 and x<15

Solution: 5<x<15

Interval Notation: (5,15)

Answer:

r=7

Step-by-step explanation:

5r-7=2r+14

add sevento both sides

5r=2r+21

Subtract 2r from both sides.

3r=21

divide both sides by 3

r=7

Answer:

-5

Step-by-step explanation:

y=3x-5

-3x+y=-5

y=-5

Answer:

First you would have to combine the numbers that are the same, so combine all the X's and the other numbers, with out a variable (without an X). The numbers with X are 2x and -4x, so you add them, you should have 2x (2+ (-4)= 2) your equation should look like this : 2x + 36 - 10= 10

Next you need to combine the other numbers, 36 and -10, add them, and you should get 26. Your problem should look like this 2x+26=10

Next you will need to subtract 26 from each side, what you do to one side of the equal sign you must do to the other. Your problem should look like this : 2x=-16

To find X you have to get X alone, so you have to divide how many x's there are, 2, so divide both sides by 2 (rembering that what you do to one side you must do to the other). So you should have x= -8

Answer:

True, all integers are rational numbers.

Step-by-step explanation:

Because each integer can be written as n/1 and integers can be positive and negative. For example, 3= 3/1 , 3 is the rational number. But all rational numbers like 1/2 =0.5 are not an integer. (fractions, decimals are not integers.)

Answer: f(x) = 10in*cos(x*2*pi/60s) + 10in*sin(x*2*pi/60s) + 108in.

Step-by-step explanation:

When we have a circular motion, we can write this as:

f(x) = A*sin(k*x + f) + A*cos(k*x + f) + C.

where:

k is a constant that depends on the period.

f is a phase shift.

C is the mean height of the circular motion, in this case will be equal to the height of the center, that is 9ft.

C = 9ft.

A is the amplitude of the motion, in this case is equal to the radius, that is equal to the lenght of the second hand

A = 10in

But we should write both quantities in the same units, so we have:

1ft = 12in

then:

C = 9ft = 9*12in = 108in

Then our equation is:

f(x) = 10in*cos(k*x + f) + 10in*sin(k*x + f) + 108in

now, x = 0s coincides with the noon

so at x = 0s, the second hand is pointint to the twelve, this means that is in the max height, so we have:

F(0s) = 10in*cos(0 + f) + 10in*sin(0 + f) + 108 in

Now, the maximum value will be when the value inside the sinusoidals is 0.

(because cos(0) = 1 and sin(0) = 0)

then we have that f = 0.

Now, we know that it takes 60 seconds to do a full revolution, and for the sinusodial functions the period is 2*pi

Then we have:

c*60s = 2*pi

c = 2*pi/60s.

Then the equation is:

f(x) = 10in*cos(x*2*pi/60s) + 10in*sin(x*2*pi/60s) + 108in.

Answer:

7

Step-by-step explanation:

First, plug-in f(-3) into t in the function:

[tex]f(-3)=-2(-3) +1[/tex]

Second, multiply -2 and -3 to get 6:

[tex]f(-3)=-2(-3)+1[/tex]⇒[tex]f(-3)=6+1[/tex]

Third, add 6 and 1 to get your answer:

[tex]f(-3)= 6+1[/tex]⇒[tex]f(-3)=7[/tex]

Answer:

-3

Step-by-step explanation:

To find the common difference take the second term minus the first term

27 - 30 = -3

Check by taking the third term and subtracting the second term

Answer:

Mary messed up on the second step. She should have also added 6 to the 24. If she had solved the equation the correct way her answer would have been m=10

Step-by-step explanation:

3m-6=24

Add 6 on both sides

3m=30

Divide by 3 on both sides

m=10

Step-by-step explanation:

Equation 1: 9x + 2y = 24y, 9x = 22y, x = 22/9 y.

Equation 2: 24y = 6x + 19,

24y = 6(22/9 y) + 19

24y = 44/3 y + 19

28/3 y = 19

Hence, y = 19 * 3/28 = 57/28.
