The Equation game

[WEAREBORG4102 0]

Shrek came up with this idea and said I could use it.

The goal is to solve the last equation and post or create your own to solve!!!! Give certain parameters in which to solve such as the axis of symmetry or a certain variable(s). Please explain your answer!

It's like yes and no .

Here are some examples:

4x^2+6x-5 Give the axis of symmety for this parabola.

The answer is x= -6/8. That is because x=-b/2a

Quadratics.....

Understand?

I'll start:

Give the y intercept, vertex, and x intercepts(s) of this equation

 

y=-4x^2+7x+8

Click for Spoiler:

y=-4x^2+7x+8

 

 

please round to the nearest tenth

Bet you'll get alot of replies on this one,

It's a quadratic

[WEAREBORG4102 0]

The answer is

 

Click for Spoiler:

0,8 (y coordinate)

 

 

 

Click for Spoiler:

7/8, 793/64 (vertex)

 

 

 

Click for Spoiler:

(-7(+ or -) the square root of 177)/-8

 

 

The next equation is easier.

 

y=4x+18

y=14x/2+5

 

solve for x

 

Click for Spoiler:

use substitution

[please delete 0]

y=4x+18

y=14x/2+5

 

subtract

 

-10x/-2+13

 

nope not going to work for me... *goes back to alegbra 1 book*

I know what it is, and your tricky, I think. Still working on it.

I get confused with anything beyond 2+2=4. I'm gonna guess Charles Dickens, that's my answer on any question where I don't know the answer.

Come on!!!!!!

This is easy!!!!!
