Answer 1

Answer:

d is not a function

Step-by-step explanation:

Answer 2
D is not a function because functions only have one y value corresponding to each x value (1 y value for 1 x value). When you have x = 2, y can be an infinite number of numbers so it can't be a function!

A line passes through the points (-4,-1) and (4,3). A second line passes through the points (-2,-2) and (2,6). At what point do the two lines intersect

Answers

Answer:

(-2/3 , 2/3)

Step-by-step explanation:

Line 1: (-4,-1) (4,3)

m = (3 - -1) / (4 - -4) = 4/8 = 1/2

equation: (y-3)/(x-4) = 1/2          y-3 = 1/2 x - 2

y = 1/2 x + 1 ....(1)

Line 2: (-2,-2) (2,6)

m = (6 - -2) / (2 - -2) = 8/4 = 2

equation: (y-6)/(x-2) = 2              y-6 = 2x - 4

y = 2x + 2  ...(2)

(2)-(1): 0 = 3/2x + 1

3/2 x = -1            x = - 2/3

y = 1/2 * (-2/3) + 1 = 2/3

What is the slope of the line that passes through these two points (-2,4) (3,4)?

Answer:

3 = ?

Step-by-step explanation:

The triangles are similar, so we  can use ratios

15           12 -2

------   = --------------

15+?          12

15           10

------   = --------------

15+?          12

Using cross products

15 * 12 = 10 ( 15+?)

180 = 10 ( 15+?)

Divide each side by 10

18 = 15+?

Subtract 15 from each side

18-15 = 15+?-15

What is the probability that the spinner will land on either yellow (y) or green (g)?

A: 1/4.
B: 1/3.
C: 1/2.
D: 2/3.

Answers

Answer:

I believe it's 1/3

I haven't done these in a while, but basically since there is 6 places and it's asking the probability of it landing on 2 out of the 6, so the answer would be 2/6. Since the answer isn't there, just simpify. 2/6 simplified is 1/3. I'm so sorry if wrong, I haven't done this in a while!

It’s B because when you put the 2/6 and reduce it it’s 1/3

Which expression is equivalent to 5 ( x + 8)?

Answers

Answer:

your answer is (B) 5x-0.4

Step-by-step explanation:

The equivalent expression for the given function is -

y = 5x + 40.

What is function?

A function is a relation between a dependent and independent variable. We can write the examples of functions as -

y = f(x) = ax + b

y = f(x, y, z) = ax + by + cz

Given is the expression -

5(x + 8)

We can write the equivalent expression for the given function is -

y = 5(x + 8)

y = 5x + 40

Therefore, the equivalent expression for the given function is -

y = 5x + 40.

when looking at an equation, how do you know if it has direct variation​?

Answers

Answer: A direct variation is when x and y (or f(x) and x) are directly proportional to each other... For example, if you have a chart that says x and y, and in the x column is 1, 2 and 3, and the y column says 2, 4 and 6... then you know it's proportional because for each x, y increases by 2.
