The trend line passes through (10,9) and (35,0). Write an equation for the trend line.

Answers

Answer: Solution :  

Step 1 :

Make a scatter plot of Lily’s running data.

Step 2 :

To draw a trend line, use a straight edge to draw a line that has about the same number of points above and below it. Ignore any outliers.

Step 3 :  

Find the slope of the trend line.

The line passes through points (2, 20) and (4.5, 45).

Use the slope formula.  

m  =  (y2 - y1) / (x2 - x1)

Substitute x1, = 2, y1 = 20, x2 = 4,  and y2 = 45.

m  =  (45 - 20) / (4.5 - 2)

m  =  25 / 2.5

m  =  10

Step 4 :  

Find the y-intercept of the trend line.

Slope-intercept form equation of a line :  

y  =  mx + b

Plug y = 20, m = 10 and x = 2.  

20  =  10 · 2 + b

20  =  20 + b

Subtract 20 from both sides.  

0  =  b

Step 5 :  

Use your slope and y-intercept values to write the equation.

Slope-intercept form equation of a line :  

y  =  10x + 0

So, the equation for the trend line is

y  =  10x

Step-by-step explanation:

1/2 of 12/12 is 6/12.

So, this means: 1/12 + 1/2 = 7/12

can you help me solve the linear equation algebraically y=-x-3. y=-2x-8​

Answers

Answer:

I can't it's to hard try studying

Answer:
x=-5
y=2

Explanation:
Since both of these equations are equal to y, they have to be equal to each other. Set them equal to each other like this: -x-3= -2x-8. Multiply everything by negative 1 to get rid of the negative signs. The equation will look like this: x+3= 2x+8. Than subtract the x from both sides. Than subtract 8 from both sides. That should get you to x=-5. Than plug in -5 into the x value for one of the linear equations. It will get you 2 for the y.

The equation y+ 3 = 5(x - 3) represents a linear function. What is the y intercept of the equation?

Answers

Answer:

-18

Step-by-step explanation:

If you're looking for the y-intercept for this equation this means that x = 0.

So substitute x as 0 in the equation and you'll get the following.

y + 3 = 5 (0 - 3)

y + 3 = -15

y = -18

If the measure of AngleB is 40°, what measures can AngleA and AngleC be? Select the three correct answers. 20° and 30° 30° and 110° 55° and 85° 60° and 90° 70° and 70°

Answers

Answer:

30° and 110°

55° and 85°

70°and 70°

Step-by-step explanation:

Given that :

Angle B = 40°

Sum of angles in a triangle :

Angle (A + B + C) = 180°

A + 40 + B = 180

A + C = 180 - 40

A + C = 140°

From the Given options ;

The sun of the Angles Given must add up to 140°

Hence,

30° and 110° = 140°

55° and 85° = 140°

70°and 70° = 140

7(x-2)=28 Can somebody help me and show the steps?

Answers

Since the 7 is in front of the parentheses you must multiply it by everything inside the parentheses. 7 times X is 7X and 7 times -2 is -14. Then you need to make the X be by itself on one side, to do that you have to add 14 to -14 to make it disappear, and also add 14 to the other side, to 28. Then you divide both sides by 7 to make X be by itself.

7(x-2)=28
7X-14=28
7x=42
X=6
