Y = mx + b
m = slope
b = y intercept.

6x - 3y = 12
-3y = -6x + 12
-3y/-3 = -6x/-3 + 12/-3
y = 2x - 4
m = slope = 2
b = y intercept = -4

y = -x + 6
m = -1 ; b = 6

(-4,-2)
Since it is perpendicular to y = -x + 6, the slope of (-4,-2) is the opposite reciprocal of the -1.

m = +1

-2 = 1(-4) + b
-2 = -4 + b
b = -2 + 4
b = 2

y = x + 2  is the equation of the line passing through the point (-4,-2)

Equation of a line is given by y = mx + c; where m is the slope and c is the y-intercept.
For line 6x - 3y = 12
3y = 6x - 12
y = 6/3 x - 12/3
y = 2x - 4

Therefore, slope is 2.

If a baking tray is 700mm by 600mm, how many of 25cm in diameter can fit into the baking tray?
Trava [24]
1cm=10mm
700mm= 70cm
600mm=60cm

70cm:25cm=2,8 - on length only 2 fit into

60cm:25=2,4 - on width only 2 fit into

Two 25cm in diameter fit into the baking tray.

A group of 52 people attend a ball game there were three times as many children as adults in the group set up a system of equati
xxTIMURxx [149]

Answer:

Therefore there total of 39 children presented in group of people who attended a ball game.

Step-by-step explanation:

Given:

Total people present=52 .

And there are 3 times children as adults

To Find:

No.of Children Present in Group.

Solution:

<em>Consider  'x'  be the children and 'y' be Adults presented in group.</em>

<em />

So there are total of 52 people.

Therefore Equation becomes,

x+y=52.

And also there  are 3 times children presented in group as adults were.

So

Children=3 times adults

i.e.x=3y

Using in above Equation we get ,

x+y=52

3y+y=52

4y=52

y=52/4

y=13

Hence there are 13 adults  presented in group

So ,

No.of Children=x=3y

=3(13)

=39

No.of.Children =39

PLZ HELP AND SHOW YOUR WORK &lt;3333<br><br><br> Substitution.<br><br> 3x+2y=11<br><br> y=5x-1
liraira [26]
Hey there! :D

Substitute y for 5x-1. 

3x+2y=11

y=5x-1

3x+2(5x-1)=11

3x+10x-2=11

13x-2=11

13x=13

x=1

Now, plug that in to find y.

y=5x-1

y=5(1)-1

y=5-1

y=4

(1,4) <== the solution

I hope this helps!
