Aleks [24]

lets say there are 100 girls. 
4/5 of 100 is 80, so 80 girls have brown hair.
3/4 of the 80 who have brown hair have long hair.
3/4 of 80 is 60.
so we know that out of 100, 60 have long brown hair.

Find the quotient. If possible, rename the quotient as a mixed number. Select the answer that is in simplest form. 3/5 ÷ 1/2 =
Vanyuwa [196]
3/5 divided by 1/2 equals 6/5 or 1 and 1/5! 
(My method- Keep 3/5, change the division sign to a multiplication sign, and flip 1/2 to 2/1. Multiply strait across and you get 6/5! 5 can go into 1 one time and that leaves 1/5! So your answer is 1 and 1/5! Hope it helps!)

Answer:

Line 1 Slope: - 4/3

Line 2 Slope: 3/4

Line 3 Slope: 3/4

---------------------------------------------------------------------------------------------------------------

Line 1 and Line 2: Perpendicular

Line 1 and Line 3: Perpendicular

Line 2 and Line 3: Parallel

Step-by-step explanation:

Line 1: Passes through (6, -4) and (0, 4).

We first find the slope by using this equation (y2 - y1) / (x2 - x1) -    

(4 - (-4)) / (0 - 6)    

(4 + 4) / (-6)  

8 / -6

-4 / 3  

Slope = - 4/3

___________________________________________________________

Line 2: Passes through (-4, -2) and (8, 7).

We first find the slope by using this equation (y2 - y1) / (x2 - x1) -    

(7 - (-2)) / (8 - (-4))    

(7 + 2) / (12)  

9 / 12

3 / 4  

Slope = 3/4

___________________________________________________________

Line 3: Passes through (-4, -5) and (4, 1).

We first find the slope by using this equation (y2 - y1) / (x2 - x1) -    

(1 - (-5)) / (4 - (-4))    

(1 + 5) / (4 + 4)  

6 / 8

3 / 4  

Slope = 3/4

Line 1 and Line 2: Perpendicular

Line 1 and Line 3: Perpendicular

Line 2 and Line 3: Parallel

Y+x=0 how do I get the slope intercept for this equation ?
Elza [17]

Answer:

Well using this

Step-by-step explanation:

The slope intercept formula is

y=mx+b

M is nothing right now but we can subsitute it with 1

So lets imagine it

y+1x=0

0 in this case is the y intercept

0 is the “b”

Even if we move it around

y=0-1x

Or

y=-1x+0

Since there can’t be negtaive 0

The y intercept is (0)
