What are the x and y intercepts for the equation 16x-4y=2?? NEED ANSWERS ASAP WORTH 70pts!!
Hatshy [7]

Answer:

<em>x-intercept = 1/8</em>

<em>y-intercept = -1/2</em>

Step-by-step explanation:

Let y = 0, and solve for x to find the x-intercept. Then let x = 0 and solve for y to find the y-intercept.

x-intercept

16x - 4y = 2

16x - 4(0) = 2

16x - 0 = 2

16x = 2

x = 2/16

x = 1/8

x-intercept = 1/8

y-intercept

16x - 4y = 2

16(0) - 4y = 2

0 - 4y = 2

-4y = 2

y = 2/-4

y = -1/2

y-intercept = -1/2

How do i do this ???
Westkost [7]

a peculiar thing about the centroid of a triangle, is that it cuts all the medians in a 2:1 ratio, so JP : PM are on a 2:1 ratio, thus

\bf JP:PM\qquad 2:1\qquad \cfrac{JP}{PM}=\cfrac{2}{1}\implies \cfrac{27}{PM}=\cfrac{2}{1}\implies \cfrac{27}{2}=PM\\\\-------------------------------\\\\JM=JP+PM\implies JM=27+\cfrac{27}{2}\implies JM=\cfrac{54+27}{2}\\\\\\JM=\cfrac{81}{2}\implies JM=40\frac{1}{2}
