Which equation is a linear function?

Answer:

5 + 2x = 5x + 4

-2x             -2x

5 = 3x + 4

-4          -4

1 = 3x

Divide by 3 on both sides.

1/3 = x

Answer:

cos(θ) =  -3/√10

sin(θ) =   1/√10

tan(θ) =  -1/3

Step-by-step explanation:

When we have a point (x, y), the angle generated between the positive x-axis and a ray that connects the origin and the point, is defined by:

cos(θ) = x/(√(x^2 + y^2))

sin(θ) = y/(√(x^2 + y^2))

tan(θ) = y/x

Now we have the point (-3, 1), then we have:

x = -3

y = 1

√(x^2 + y^2) = √((-3)^2 + 1^2) = √10

Then we just need to replace these values in the given formulas:

cos(θ) = x/(√(x^2 + y^2)) = -3/√10

sin(θ) = y/(√(x^2 + y^2)) =  1/√10

tan(θ) = y/x = 1/-3 = -1/3

Answer:

It's the last option, (a-c)√x + b√y

Step-by-step explanation:

Answer:

1) The terminal side lies in quadrant 2

2) cosФ = -15/17

3) tanФ = -8/15

Step-by-step explanation:

1) First, we should realize that since sinФ = 8/17, it is positive. Thus, Ф must be in quadrants 1 or 2. And since cosФ is negative, Ф must be in quadrant 2 because cos, sin, and tan are all positive in quadrant 1

2) Next, we must realize that the sides given are a 8-15-17 right triangle. And in this case, since sinФ = 8/17, cosФ should be 15/17. But since cosФ is negative, cosФ = -15/17

3) Lastly, tanФ is opposite/adjacent. Since opposite of Ф is 8 and adjacent of Ф is 15, then tanФ should be 8/15, but since Ф is in quadrant 2, then tanФ is -8/15

Answer:

A; (4,4), (8,8) and (12,16)

Step-by-step explanation:

The value x starts with 4 and add 4 to each term

The value y start with 4 and each term next is multiplied by 2

So for x, we have;

4 , (4 + 4) and (4 + 4 + 4)

= 4,8 and 12

For y;

we have ;

4, (4 * 2) , (4 * 2 * 2)

= 4, 8, 16

so pairing up, we have;

(4,4), (8,8) and (12,16)

Answer:

a. 10^- 3

b. 10^- 7

c. 10^- 8

d. 10^- 9

e. 1 / 10^6

a.

1 / 10. 1 / 10. 1 / 10

= 1 / ( 10 x 10 x 10 )

= 1 / 1000

= 1 / 10^3

= 10^- 3

b.

1 / 10. 1 / 10. 1 / 10. 1 / 10. 1 / 10. 1 / 10. 1 / 10

= 1 / ( 10 x 10 x 10 x 10 x 10 x 10 x 10 )

= 1 / 10000000

= 1 / 10^7

= 10^- 7

c.

( 1 / 10. 1 / 10. 1 / 10. 1 / 10. )^2

= ( 1 / 1000 )^2

= ( 1 / 10^3 )^2

= ( 10^- 3 )^2

= 10^( - 3 x 2 )

= 10^- 6

d.

( 1 / 10. 1 / 10. 1 / 10 )^3

= ( 1 / 1000 )^3

= ( 1 / 10^3 )^3

= ( 10^- 3 )^3

= 10^( - 3 x 3 )

= 10^- 9

e.

( 10. 10. 10. )^- 2

= ( 10^3 )^- 2

= ( 1 / 10^3 )^2

= 1 / 10^( 3 x 2 )

= 1 / 10^6

Answer:

Step-by-step explanation:

The first thing they did was factor the denominators

so

x²-3x+2= (x-1)(x-2)

and

x²-1= (x-1)(x+1)

To add two fractions their denominators need to be the same

to accomplish this they mulitpied both sides of the fraction

after that they mulitplied what was in the numerator and combined like terms

Because the denominator cannot equal 0 x≠ -1, 1, 2

Answer:

x=17

Step-by-step explanation:

you have to use the 2 secants rule

8(8+13) = 7(7+x) distribute in parenthesis

64+ 104 = 49 +7x  isolate variable

64+104-49 = 7x combine like terms

119 =7x divide both sides by 7

17 =x

Answer:tbh i think the answer H

Step-by-step explanation:

Answer:

8.5 = $35,000

2% = $18,000

Step-by-step explanation:

two equations can be derived from the question

x + y = $53,000 equation 1

0.02x + 0.085y = $3,335.00. equation 2

x = amount invested in 2% bond

y =  amount invested in 8.5% bond

multiply equation 1 by 0.02

0.02x + 0.02y = 1060 equation 3

subtract equation 2 from 3

0.065y = 2275

y = 35,000

substitute for y in equation 1

53,000 - 35,000 = 18,000

Step-by-step explanation:

Find the diagram attached

12) Given the following

m<EF = 3x - 6

m<GF = 15x - 30

From the diagram, arcEf and arcGF are supplementary. Hence;

arcEF + arcGF = 180

3x - 6 + 15x - 30  = 180

18x - 36 = 180

18x = 180 + 36

18x = 216

x = 216/18

x = 12degrees

arcEF = 3x-6

arcEF = 3(12) - 6

arcEF = 36 - 6

arcEF = 30degrees

arcGF = 180 - aecEF

arcGF = 180 - 30

arcGF = 150degrees

Since arcDE = arcGF (vertical angles), hence arcDE = 150degrees

arcDFG = arcDG+arcGF

arcDFG = 30 + 150

arcDFG = 180degrees

13) arcMN = arcQP (vertical angles)

12x-5 = 6x+3

Collect like terms

12x - 6x = 3 + 5

6x = 8

x = 8/6

x = 1.3

arcMN =12x - 5

arcMN = 12(8/6) - 5

arcMN = 16 - 5

arcMN = 11degres

arcNP = 180 - arcMN

arcNP = 180 - 11

arcNP = 169degrees

Since arcNQP lies on straight line, hence arcNQP is 180degrees

Answer:

The answer is 9/10

Step-by-step explanation:

8/10 is the same thing as ⅘, ⅘ is just simplified

⅖ is less than ⅘ so it would come before c

6/5 is more than 1 so it wouldn’t be on that number line.

Answer:

OK.

My answer is based on 2 things.

1. That the furthest point on the left is 0( That other little distance is ignored)

2. That the point C is equidistant from 4/5 and 1.

If so..

Then

4/5 + x + x =1

4/5 +2x = 1

2x= 1-4/5

x=1/10

Now

From 4/5 to C is x...

Then Position C would be

4/5 + 1/10

c= 9/10

Or by simply making guesses...

All Other options are greater than 1... So It can't be those cos C is less than 1

Answer:

x = 25 and x = 47

Step-by-step explanation:

(9)

The given angles are vertical and congruent , then

2x + 10 = 60 ( subtract 10 from both sides )

2x = 50 ( divide both sides by 2 )

x = 25

(10)

The given angles are vertical and congruent , then

2x + 6 = 100 ( subtract 6 from both sides )

2x = 94 ( divide both sides by 2 )

x = 47
