Answer:

$\sqrt[7]{x^9}$

Step-by-step explanation:

its kinda difficult for me to explain so i guess just use this equation next time:

If y = kx, and x = 3 and y = 15, calculate k.

kenny6666 [7]

Answer:

k = 5

Step-by-step explanation:

Since the equation is y = kx and x equals 3 while y equals 15, in order to solve this equation we are going to have to substitute the variables with their answers:

x = 3

y = 15

15 = 3k

Now we divide 3 from both 3x and 15 to segregate the variable x:

15/3 = 3k/3

5 = k

Now to check our work we are going to substitute 5 for the variable k, 3 for the variable x and 15 for the variable y.

y = kx

15= (5)(3)

15 = 15

Tada, I hope this helps you!

1. Which relation is a function?

Amiraneli [1.4K]

Answer:

1. (0, 4), (-4, 2), (7, 1), (-8, 2)

2. (2, 4), (-3, 2), (9, 1), (-7, 2)

Step-by-step explanation:

1. Since there is 1 value of y for every value of x in (0, 4), (-4, 2), (7, 1), (-8, 2) this relation is a function.

2. Since there is 1 value of y for every value of x in (2, 4), (-3, 2), (9, 1), (-7, 2) this relation is a function.

∠1 and ∠2 are supplementary angles. ∠1 and ∠3 are vertical angles. If m ∠2=72 degrees, then find m ∠3

JulsSmile [24]

Answer:

m<3 = 108

Step-by-step explanation:

Since <1 and <2 are supplementary, the equation is:

<1 + <2 = 180

Since <1 and <3 are vertical angles. the equation is:

<1 = <3

To find m<3:

<2 + <3 = 180

72 + <3 = 180

<3 = 180 - 72

<3 = 108
