HELP ME WITH LINEAR RELATIONSHIPS MATH PLEASE !!’

Answers

Answer:

y = -1/4x + 2

Step-by-step explanation:

Pick two points on the graph. Points (-4, 3) and (4, 1).

[tex]\frac{x_{2} - x_{1} }{y_{2} - y_{1} }[/tex]

[tex]\frac{3-1}{-4-4}[/tex]

= [tex]-\frac{1}{4}[/tex]

Slope is [tex]-\frac{1}{4}[/tex].

The y-intercept is the point where the line intersects the y-axis. In this case, it's (0, 2). So +2.

y = -1/4x + 2

The value of y is proportional to x. When x=3 , then y = 15. Which equation represents the relationship between x and y?
A.y=5x
B.y=12x
C.y=0.2x
D.y=45x

Answers

Answer:

A. y = 5x

Step-by-step explanation:

Direct proportion equation:

y = kx, where k is the coefficient of proportionality

We have:

x = 3 and y = 15

Using the equation to find the value of k:

15 = 3kk = 15/3k = 5

The equation of the line:

y = 5x

Correct choice is A

4. (2,1) 5. (-2,1) 6. (8, 80)

Step-by-step explanation:

4.

2x + 4y - 2x + 2y = 8 - 2

6y = 6

y = 1

2x + 4 = 8

2x = 4

x = 2

(2,1)

5.

3x + 4y + 6x - 4y = -2 - 14

8x = -16

x = -2

-6 + 4y = -2

4y = 4

y = 1

(-2,1)

6.

multiply first equation by 4

4y = 40x

4y + 40x + 6y = 40x + 800

10y = 800

y = 80

80 = 10x

x = 8

What would the measure of the third angle
equal?

Answers

Answer:

55

Step-by-step explanation:

180−43−82=55(angles of a triangle add upto 180)

What would the measure of the third angle equal?

Well given that all 3 vertices of a triangle are supposed  to be a sum of 180*

Hence this information side E is 82* and side H is 43* and when added up they equal 125 so then you would subtract 180 - 125 =  55\

Therefore, side T = 55*
