The process is similar to (and easier* than) adding three 4-digit numbers. Add the numbers in each column.

The sum is ...
(2+1-3)x³ +(-4+6+2)x² +(6-8-4)x +(-3+12-7)
= 0x³ +4x² -6x +2

The sum is 4x² -6x +2

_____
* The process is easier because there are no "carry" operations from one column to another as there may be when adding multi-digit numbers.

Given the function g(x)=−2x−8, evaluate g(0).

Vera_Pavlovna [14]

Answer:

g(0) = -8

Step-by-step explanation:

When you plug in a zero for the x the equation will look like

g(0) = -2(0) - 8

-2 times 0 = 0 so g(0) = -8

Which ordered pair is the solution to this system of equations?<br> y=2x-3 <br> y=7-0.5x

disa [49]

Answer:

(4, 5)

Step-by-step explanation:

y = 2x - 3

y = 7 - 0.5x

y is already isolated on both equations, set them equal to each other:

2x - 3 = 7 - 0.5x

add 3 to both sides:

2x = 10 - 0.5x

add 0.5x to both sides:

2.5x = 10

divide by 2.5:

x = 4

plug in 4 for x on either equation and solve for y:

y = 2(4) - 3

y = 8 - 3

y = 5

(4, 5)

The graph of a linear function passes through the point (-1, 2) and has a slope of 3. What is the equation of the function in sl

Harman [31]

Answer:

The equation of the function in slope-intercept form is y = 3 x + 5 .

Step-by-step explanation:

Given as :

A line passes through the point ( - 1 , 2 )

i.e ( x , y ) = ( - 1 , 2 )

The slope of the line is 3

The equation of line in slope intercept form

y - $\textrm y_1$ = m ( x - $\textrm x_1$ )

Where m is the slope of the line

So, y - 2 = 3 ( x - ( - 1 ) )

Or, y - 2 = 3 ( x + 1 )

Or, y - 2 = 3 x + 3

Or, y = 3 x + 3 + 2

∴ y = 3 x + 5

Hence The equation of the function in slope-intercept form is y = 3 x + 5 . Answer
