Answer:

x = -10

Step-by-step explanation:

Step 1: Write equation

2.50x + 15.00 = 1.00x

Step 2: Solve for x

Subtract 1.00x on both sides: 1.50x + 15.00 = 0
Subtract 15.00 on both sides: 1.50x = -15.00
Divide both sides by 1.50: x = -10

Step 3: Check

Plug in x to verify it's a solution.

2.50(-10) + 15.00 = 1.00(-10)

-25 + 15.00 = -10

-10 = -10

Answer:

x = -10

Step-by-step explanation:

multiply both sides by 10:

2.50x*10+15*10=1.00x*10

Refine:

25x + 150 = 10x

Subtract 150 from both sides:

25x + 150 - 150 = 10x - 150

Simplify:

25x = 10x - 150

Subtract 10x from both sides:

25x - 10x = 10x - 150 - 10x

Simplify:

15x = -150

Divide both sides by 15:

15x/15 = -150/15

Simplify:

x = -10

Use linear regression to find the equation for the linear function that best fits this data. Round both numbers to two decimal p

natta225 [31]

Answer:

The equation of the linear function that best fits the data is,

y = 18.66x + 66.87.

Step-by-step explanation:

The line of best is of the form: y = mx + b.

Here, m = slope of the line and b = intercept.

The formula to compute the intercept and slope are:

$b=\frac{\sum Y.\sum X^{2}-\sum X.\sum XY}{n.\sum X^{2}-(\sum X)^{2}}$

$m=\frac{n.\sum XY-\sum X.\sum Y}{n.\sum X^{2}-(\sum X)^{2}}$

Consider the table below for the values of ∑ X, ∑ Y, ∑ X² and ∑ XY.

Compute the value of intercept and slope as follows:

$b=\frac{\sum Y.\sum X^{2}-\sum X.\sum XY}{n.\sum X^{2}-(\sum X)^{2}}=\frac{(793\times91)-(21\times3102)}{(6\times91)-(21)^{2}} =66.867$

$m=\frac{n.\sum XY-\sum X.\sum Y}{n.\sum X^{2}-(\sum X)^{2}}=\frac{(6\times3102)-(21\times793)}{(6\times91)- (21)^{2}} =18.657$

The line of best fit is:

$y=mx+b\\y=18.657x+66.867\\y=18.66x+66.87$

Thus, the equation of the linear function that best fits the data is y = 18.66x + 66.87.

explain the pattern used to find an answer when you multiply or divide a whole number by a power of 10

scoray [572]

When you multiply or divide a whole number by a power of ten just add the zeros. 5 to the 100000 power is 500000. Five zeros. Hope this helps. Just a little trick and pattern I noticed which helps. :)
