Answer:

  x 4,2,1,3,4

  y -2,-3,6,7,5

Step-by-step explanation:

The inverse relation has x- and y-values swapped:

  x 4,2,1,3,4

  y -2,-3,6,7,5

__

Since the same x-value appears more than once in this relation, it is <em>not a function</em>.

Which statements are true about 5/6 and 7/10 check all that apply​
Travka [436]

Answer:

<em>(1) 40 is a common multiple of 6 and 10 </em>

False:

Multiples of 6: 6, 12, 18, 24, 30, 36, 42...

Multiples of 10: 10, 20, 30, 40...

<em>(2) The fraction 5/6 is greater than 7/10</em>

True:

Find common denominators. Note that what you multiply to the denominator, you multiply to the numerator.

(5/6) x (5/5) = 25/30

(7/10) x (3/3) = 21/30

25/30 > 21/30 ∴ 5/6 is greater than 7/10

<em>(3) The fraction 42/60 is an equivalent form of 7/10</em>

True:

Find a common denominator. Note that what you multiply to the denominator, you multiply to the numerator.

(7/10) x (6/6) = 42/10

42/10 = 42/10 ∴ 7/10 = 42/10

<em>(4) The only value that can be used as a common denominator is 60</em>.

False:

While 60 is a plausible denominator, there are other denominators that can be used. Remember that what you do to the denominator, you do to the numerator.

<em>(5) Ten is a multiple of 6. </em>

False:

Multiples of 6: 6, 12, 18, 24, 30...

Find sin theta if cos theta is 4/5
Dima020 [189]

Answer:

Step-by-step explanation:

hello :

cos²θ +sin²θ = 1 and cosθ =4/5

(4/5)² + sin²θ = 1 so : sin²θ = 1 - 16/25

sin²θ = 9/25 = (3/5)²

sinθ = 3/5 or sinθ = - 3/5 because : (3/5)²= (- 3/5)²= 9/25

Which of the following equations has the same solutions as the equation 3x + 2y = -12? Check all that apply.
Mariulka [41]

Answer:

B.\ -3x - 2y = 12

C.\ 15x + 10y = -60

E.\ 6x + 4y = -24

F.\ 1.5x + y =-6

Step-by-step explanation:

Given

3x + 2y = -12

Required

Determine equations with same solution as 3x + 2y = -12

For a solution to have the same solution as 3x + 2y = -12, the equation must be expressed as 3x + 2y = -12

A.\ 3x - 2y = 12

This can not be expressed as 3x + 2y = -12

B.\ -3x - 2y = 12

Multiply through by -1

-1(-3x - 2y) = 12 * -1

3x + 2y = -12

This has the same solution as the given equation

C.\ 15x + 10y = -60

Divide through by 5

\frac{15x}{5} + \frac{10y}{5} = \frac{-60}{5}

3x + 2y = -12

This has the same solution as the given equation

D.\ 6x + 2y = -12

Divide through by 2

\frac{6x}{2} + \frac{2y}{2} = \frac{-12}{2}

3x + y = -6

This can not be expressed as 3x + 2y = -12

E.\ 6x + 4y = -24

Divide through by 2

\frac{6x}{2} + \frac{4y}{2} = \frac{-24}{2}

3x + 2y = -12

This has the same solution as the given equation

F.\ 1.5x + y =-6

Multiply through by 2

2*1.5x + 2*y =-6*2

3x + 2y =-12

This has the same solution as the given equation

G.\ x + \frac{2}{3}y = -12

Multiply through by 3

3 * x + 3*\frac{2}{3}y = -12*3

3x + 2y = -36

This can not be expressed as 3x + 2y = -12

The equations with the same solution as 3x + 2y = -12 are the ones that we were able to expressed as 3x + 2y = -12.

And the equations are:

B.\ -3x - 2y = 12

C.\ 15x + 10y = -60

E.\ 6x + 4y = -24

F.\ 1.5x + y =-6
