Slope -8 and y intercept 7
max2010maxim [7]

Answer:

The equation of Line is  y = - 8x + 7      

Step-by-step explanation:

Given as :

The slop of line is - 8

And The y intercept is 7

As the equation of line is y = mx + c

For y intercept , x = 0

So, With y intercept and slop ,

7 = (-8)× (0)+ c

Or, c = 7

So the equation of line is

y = mx + c

I.e  y = ( - 8 ) x + 7

Hence The equation of Line is  y = - 8x + 7       Answer

The graph of this system of equations is used to solve 4x2-3+6=2x4-9x3+2x What represents the solution set?
Vilka [71]

ANSWER

x coordinates of the intersection points

EXPLANATION

The given system of equations is:

y = 4 {x}^{2}  - 3x + 6

y = 2 {x}^{4}  - 9 {x}^{3}  + 2x

We want to use the graph of these functions to solve

4 {x}^{2}  - 3x + 6 =  2 {x}^{4}  - 9 {x}^{3}  + 2x

The point of the intersection of the graph gives the solution to the simultaneous equation above.

Hence the x-coordinates of the intersection points gives the solution set of

4 {x}^{2}  - 3x + 6 =  2 {x}^{4}  - 9 {x}^{3}  + 2x

The last choice is correct.

Simplify the algebraic expression by combining like (or similar) terms.<br> -7x - 8y- 5x - 6y
stira [4]

Answer:

-12x - 14y

Step-by-step explanation:

First I would move them side by side so I can see it better so:

-7x - 5x - 8y - 6y

now combine the x values together and the y values together:

-12x - 14y
