Put in function form. 8X - 7Y = 168 - 7Y = - 8X + 168 Y = 8/7X - 24 0 out Y 8/7X - 24 = 0 8/7X = 24 X = 21 ---------- 0 out X Y = - 24 ----------- (21,-24) X and Y intercepts.
It is: 8+7y
7y-8 = 6y+1 7y-6y = 1+8 y = 9
5y+8=7y subtract 5y from each side , 5y+8=7y -5y -5y 8=2y /2 /2 4=y
Well, honey, if 7y + 8 is equal to 57, then you just need to do a little math dance to solve for y. Subtract 8 from both sides to get 7y = 49, then divide by 7 to find y = 7. So, if 7y + 8 equals 57, then 2y would be 14. Hope that clears things up for ya!
Put in function form. 8X - 7Y = 168 - 7Y = - 8X + 168 Y = 8/7X - 24 0 out Y 8/7X - 24 = 0 8/7X = 24 X = 21 ---------- 0 out X Y = - 24 ----------- (21,-24) X and Y intercepts.
16+7y-8 = 7y+16-8 = 7y+8
It is: 8+7y
simplify the expression 16+7y-8 rewrite as 7(y-8)7•y= 7y 7•8= 56 7y-56 = -49y answer= 16+ (-49y)
7y-8 = 6y+1 7y-6y = 1+8 y = 9
-6y+3 = -7y+8 -6y+7y = 8-3 y = 5
5y+8 = 7y-6 5y-7y = -6-8 -2y = -14 y = 7
In order to find the slope of your line, we must first get it into y=mx+b.-9x-7y = 8-9x + 9x - 7y = 8- 7y = 9x + 8-7y/7 = 9x/7 + 8/7-y = 9x/7 + 8/7(-1) -y = 9x/7 + 8/7y = -9x/7 - 8/7The slope is -9/7 and the y-intercept is -8/7
5y+8=7y 2y=8 y=4
5y+8=7y subtract 5y from each side , 5y+8=7y -5y -5y 8=2y /2 /2 4=y
So Hey, Step 1: 7y=7y :) Step 2: 7y/7y=49^8 :) Step 3: 49^8/ = *6r1 :) So Hey Again so like you saw all the steps right?? Ok, GOOD :)............................................................................................................................................................................................................. So the reciprocal of 7y is 6^1 :)
Put in this form. Y = mX + c3X - 7Y = 8- 7Y = - 3X + 8Y = (3/7)X - 8/7===========Y intercept = - 8/7-----------------------
