can someone help me​

Answer:

r=15

Step-by-step explanation:

you would add 6 to the right side of the equation which would make it 3r = 45. Then you would divide 45 by 3, equaling 15. So that ends up with r = 15.

Answer:

1/2 is the slope

Step-by-step explanation:

y=mx+b

Answer:

1/2

Step-by-step explanation:

y=mx+b

b= y-intercept

mx=slope

so whatever is mx is the slope for example

y=1/3x+2

1/3 would be the slope because it's mx

Answer:

The first choice: 7,890 millimeters

Step-by-step explanation:

Remember that there are 100cm in a meter; there are 10mm in a centimeter.

100*10=1000

There are 1000 millimeters in a meter.

7.89*1000=7890

There are 7890 millimeters in 7.89 meters.

Answer:

x = 4

Step-by-step explanation:

( 31x + 6 ) + ( 12x + 2 ) = 180

31x + 12x + 6 + 2 = 180

43x + 8 = 180

43x + 8 -8 = 180 -8

43x = 172

43x/43 = 172/43

x = 4

Answer:

x=4

Step-by-step explanation:

31x+6+12x+2=180

43x+8=180

43x=172

x=4

Answer:

x ≥ -3/4

Step-by-step explanation:

3(2x + 5) ≥ 2(x + 6)

Distribute

6x+15 ≥ 2x + 12

Subtract 2x from each side

6x-2x+15 ≥ 2x-2x + 12

4x+15 ≥ 12

Subtract 15 from each side

4x+15-15 ≥ 12-15

4x ≥ -3

Divide each side by 4

4x/4 ≥ -3/4

x ≥ -3/4

Answer:

x < 5

Step-by-step explanation:

You can solve an inequality much like you would solve a normal equation.

There are 2x on the left side of the inequality, so divide both sides by two to find what x equals:

2x < 10

(2x)/2 < (10)/2

1x < 5

x < 5

Answer:

17/25

Step-by-step explanation:

First put it into fraction form: 68/100

Simplify in no particular order just make sure that what you do to the top, you do to the bottom: 68÷2=34 100÷2=50

Simplify as many times needed: 34/50 34÷2=17 50÷2=25

You have your answer! 17/25

The fraction in the simplest form of the decimal 0.68 is 17 /25.

The decimal form is 0.68. We are told to convert to the fraction form in it simplest form. Therefore,

0.68 = 68 / 100 = 17 / 25

The logic behind it is moving the decimal 2 points forward . This beget 2 zero's in the denominator. Moving the decimal 2 points forward makes 0.68 to become 68 and the denominator takes 2 zero's which makes it the same as 68 / 100. When we reduce it we get 17 /25.

Answer:

HERE IT IS...

Step-by-step explanation:

the domain or set of departure of a function is the set into which all of the input of the function is constrained to fall. It is the set X in the notation f: X → Y, and is alternatively denoted as. Since a function is defined on its entire domain

Answer:

Very simple!

Step-by-step explanation:

The domain of a function is where the function is defined, for the values of x.

Long story short, see the function? Where the blue line passes over the x-vales is the domain. Where there is no blue line over the x-values does not belong to the domain.

Thus, the function is defined for [tex]-8\leq x\leq 8[/tex], or [tex][-8, 8][/tex].

Answer:

x = tan⁻¹(⅘)

Step-by-step explanation:

We can solve for x by using trigonometric ratios (sin, cos, and tan)

We need to apply the appropriate ratio that uses the two sides 8 and 10 from the perspective of x. See attached image for information about ratios. (Source: Math is Fun)

The tangent ratio is opposite divided by adjacent. It will relate x to the two sides. So we would write

tan(x) = ⁸⁄₁₀

Then we simplify and move the tan to the other side by multiplying both sides by the inverse of tan (since you cannot divide by tan)

tan(x) = ⅘

x = tan⁻¹(⅘)

Then we can use a calculator to evaluate x

If you want to find y, now that you have two angles of the triangle, you can find the sum of 90 + x and subtract that from 180 (since all angles of a triangle add up to 180) to find y.
