i can

OpenStudy (i_love_my_nieces):

I will try

OpenStudy (kuoministers):

Maybe, maybe not

OpenStudy (the_beast_eli):

ii'll try

OpenStudy (anonymous):

i will

Consider solving the equation for x. 3(3x+4)−5=ax+b Which statements are true about the solution to the equation when substituting values for a and b as specified? Select all that apply.

OpenStudy (anonymous):

choices

OpenStudy (the_beast_eli):

yeah

OpenStudy (i_love_my_nieces):

Options and how many points is it worth

OpenStudy (anonymous):

If a=−3 and b=−5, then there are infinitely many solutions to the equation. If a=9 and b=−2, then there is no solution to the equation. If a=9 and b=7, then there is exactly one solution to the equation. If a=−3 and b=4, then there is exactly one solution to the equation. If a=−9 and b=13, then there is no solution to the equation.

OpenStudy (i_love_my_nieces):

Points worth?

OpenStudy (the_beast_eli):

D

OpenStudy (the_beast_eli):

or

OpenStudy (the_beast_eli):

A

OpenStudy (anonymous):

its a standard mastery test, it doesnt say

OpenStudy (anonymous):

@The_Beast_Eli Why are those the answers?

OpenStudy (the_beast_eli):

I meant B and E

OpenStudy (the_beast_eli):

there is no answer to the equation

OpenStudy (anonymous):

Ok tell you what, tell me the answeres and text me a message why

OpenStudy (anonymous):

what do you mean

OpenStudy (the_beast_eli):

ok, wait

OpenStudy (anonymous):

....

OpenStudy (the_beast_eli):

Simplifying 3(2x + 5) = ax + b Reorder the terms: 3(5 + 2x) = ax + b (5 * 3 + 2x * 3) = ax + b (15 + 6x) = ax + b Solving 15 + 6x = ax + b Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1ax' to each side of the equation. 15 + -1ax + 6x = ax + -1ax + b Combine like terms: ax + -1ax = 0 15 + -1ax + 6x = 0 + b 15 + -1ax + 6x = b Add '-15' to each side of the equation. 15 + -1ax + -15 + 6x = -15 + b Reorder the terms: 15 + -15 + -1ax + 6x = -15 + b Combine like terms: 15 + -15 = 0 0 + -1ax + 6x = -15 + b -1ax + 6x = -15 + b Reorder the terms: 15 + -1ax + -1b + 6x = -15 + b + 15 + -1b Reorder the terms: 15 + -1ax + -1b + 6x = -15 + 15 + b + -1b Combine like terms: -15 + 15 = 0 15 + -1ax + -1b + 6x = 0 + b + -1b 15 + -1ax + -1b + 6x = b + -1b Combine like terms: b + -1b = 0 15 + -1ax + -1b + 6x = 0 The solution to this equation could not be determined. There you go.

OpenStudy (anonymous):

.....ok my head hurts

OpenStudy (the_beast_eli):

ok, B & E

OpenStudy (the_beast_eli):

medal?

OpenStudy (anonymous):

thanks

OpenStudy (anonymous):

u didnt even say please

OpenStudy (the_beast_eli):

yup! and thank you

OpenStudy (anonymous):

Help me with one more?

OpenStudy (the_beast_eli):

Sorry I forgot. Medal please? One Minuet Ago

OpenStudy (the_beast_eli):

I have school, sorry.

OpenStudy (anonymous):

real quick

OpenStudy (the_beast_eli):

I'll try my best.

OpenStudy (anonymous):

Consider the equation 4x−5(2x+1)=ax+b.

OpenStudy (anonymous):

Part A Determine whether each pair of values for a and b results in the equation having no solution or one solution. Select No Solution or One Solution for each pair of values. a=−6, b=0 No Solution One Solution a=0, b=−5 No Solution One Solution a=1, b=−5 No Solution One Solution a=−6, b=5 No Solution One

OpenStudy (the_beast_eli):

I think it's C. But I am not sure.

OpenStudy (anonymous):

thnxs again

OpenStudy (anonymous):

I really appreciate it

OpenStudy (the_beast_eli):

No problem! Gtg!

OpenStudy (anonymous):

here is a gift of my gratitude

OpenStudy (the_beast_eli):

You are very Welcome

OpenStudy (anonymous):

OpenStudy (the_beast_eli):

Thanks, lol

OpenStudy (anonymous):

a guitar set!!! haha

OpenStudy (the_beast_eli):

Lol, Sweet!
