Answer:

x=29

Step-by-step explanation:

(x+3)+(x-1)+(x+1)=90

x+3+x-1+x+1=90

3x+3=90

3x=90-3

x=87/3

x=29

x+3=32

x+1=30

x-1=28

Checking

(x+3)+(x-1)+(x+1)=90

(29+3)+(29-1)+(29+1)=90

32+28+30=90

90=90

X intercept -7 y intercept -5
Fittoniya [83]
The x-intercept of a line is when the y coordinate is equal to 0. So, the x-intercept would be (0,-7).

The y-intercept of a line is when the x coordinate is equal to 0. So the y-intercept would be (-5,0).

To find the equation of a line, you need the slope and the y-intercept.
We already know the y intercept is -5. The equation for a line is:

Y=mx+b

m stands for slope
b stands for the y intercept.

To find the slope, use the equation-

y1-y2
--------
x1-x2

Another way to say that is the change in y over the change in x.

Plug in the the 2 coordinate points you know, which are (-7,0) and (0,-5).

0+5
-------,
-7-0


5/-7.

The slope is 5/-7
The Y intercept is -5

The equation of the line is y= 5/-7x -5

The coordinate point for the x intercept is (-7,0)
The coordinate point for the y intercept is (0,-5)

Given the monthly stock prices :

January = $3.50

February = $2.25

March = $5.00

The average monthly change in price of XYZ stock from. JANUARY through MARCH is;

(January + February + March) / 3

Average monthly change :

(3.50 + 2.25 + 5.00) / 3

$10.75 / 3

= $3.583
