Answer:

There is no repeated x or y values

We know that a relation is a function, when each input of x value gives exactly one output of y-value.

In a function two or more x-coordinates can give same y-value, but one x-value cannot give two y-values.

We can see that in our given set each x-value corresponds to exactly one y-value, therefore, the given set represents a function.

Step-by-step explanation: Hopefully this helped, if not HMU and I will get you a better answer

-Have a great day! :)

Find x and y pls help

ahrayia [7]

Answer:

x = 14

Step-by-step explanation:

110 + 5x = 180

-110 -110

5x = 70

divide by 5 on both sides

x = 14

to find y add 70 + 40 + missing angle = 2y

missing angle is 70 because 70+40+70 = 180

so 2y = 110

y = 55

The equation p= 2.5m + 35 represents the price p of a bracelet, where m is the cost of the materials. The price of a bracelet is

Klio2033 [76]

P= 2.5m + 35 (replace p with 115)
115= 2.5m + 35 (subract 35 from each side)
115 - 35 = 2.5m
80 = 2.5m (divide 2.5 from each side)
80/2.5= 2.5m/2.5
32 = m

The price of the materials is $32

Which equations represent the line that is parallel to 3x − 4y = 7 and passes through the point (−4, −2)? Select two options. y

xz_007 [3.2K]

Answer:

The equation of the parallel line to the given equation is

3 x-4 y = -4 and

The equation of the parallel line to the given equation is

$y = 1 + \frac{3 x}{4}$

Step-by-step explanation:

Explanation:-

Given equation of the line 3 x -4 y = 7 and given point ( -4 , -2 )

The equation of the parallel line to the given equation is

3 x - 4 y = k

it is passes through the point ( -4 , -2)

3 (-4) - 4 ( -2) = k

-12 +8 = k

k = -4

The equation of the parallel line to the given equation is

3 x- 4 y = -4

Dividing '4' on both sides , we get

$\frac{3 x-4 y}{-4} = 1$

$\frac{-3 x}{4} +y =1$

$y = 1 + \frac{3 x}{4}$

Conclusion:-

∴ The equation of the parallel line to the given equation is

3 x- 4 y = -4

and

The equation of the parallel line to the given equation is

$y = 1 + \frac{3 x}{4}$
