LCM of 5(y - 4)(y + 4) and (y + 4) is 5(y - 4)(y + 4)
-----------------------------------------------------------------------
Answer: 5(y - 4)(y + 4) (Answer D)-----------------------------------------------------------------------
Answer:
y = -5/6x - 4/3 (slope-intercept form)
Step-by-step explanation:
<u>From my understanding, we have to convert this equation into slope intercept form.</u>
<em>Slope-intercept form: y=mx + c</em>
<em>where m is the slope and x is the y-intercept</em>
5/8x+3/4y=-1
<em>Make y the subject</em>
3/4y = -1 - 5/8x
3y = -4 - 5/2x
y = -4/3 - 5/6x
y = -5/6x - 4/3 (slope-intercept form)
Slope or m = -5/6
y-intercept or c = -4/3
Answer:
The solution of this system is (9, 2).
Step-by-step explanation:
Substitute x - 7 for 'y' in the first equation. We get:
x - 3(x - 7) = 3 Doing this temporarily eliminates the variable 'y'.
Now perform the indicated multiplication, and then combine like terms:
x - 3x + 21 = 3, or
-2x = -18
so that x = 9. Substituting 9 for x in the second equation, we get:
y = 9 - 7, or y = 2.
The solution of this system is (9, 2).
It's a because 5 divided by 9 equals .555555555555556. The 6 is just from rounding the number. Otherwise the five would go on forever. The bar means go on forever. So it .5 with a bat over the 5
