Question?

Question??

OpenStudy (anonymous):

complete the standerd form of the equation y=10-5/2x

OpenStudy (anonymous):

_x+_y=20

OpenStudy (anonymous):

Wait y = 10-5?

OpenStudy (anonymous):

and What is the x-intercept of the line with the equation 1/3x+y=-15(_,0)

OpenStudy (slinley):

y = 10^-5

OpenStudy (slinley):

wait :)

OpenStudy (slinley):

y = 1/3 0I thinkkkk

OpenStudy (anonymous):

but thats not what it asks

OpenStudy (anonymous):

theres two seperate questions

OpenStudy (anonymous):

@sammixboo

OpenStudy (anonymous):

@aum

OpenStudy (slinley):

Can you give me a medal and fan me? I'll give you the same, Thanks!

OpenStudy (aum):

\[ y = 10 - \frac 52x \\ \text{Multiply by 2:} \\ 2y = 20 - 5x \\ \text{Add 5x} \\ 5x + 2y = 20 ~~~\text{ is the standard form.} \]

sammixboo (sammixboo):

Sorry for not responding! Do you still need help?

OpenStudy (anonymous):

on the second question

OpenStudy (aum):

\[ \frac 13x + y = -15 \\ \text{To find x-intercept, set y = 0 and solve for x.} \\ \]

OpenStudy (aum):

\[ \frac 13x + y = -15 \\ \text{put y = 0} \\ \frac 13x + 0 = -15 \\ \text{To solve for x, multiply by 3:} \\ x = -45 \\ \text{x-intercept: }~~(-45, 0) \\ \]
