Answer:

The slope would be 1/2

Step-by-step explanation:

y= mx +b

m= slope

perpendicular lines have slopes that are multiplied in order to get -1

these are important

2x + y = 4

subtract 2x

y=-2x +4

your slope is -2

-2 * ? = -1

? = -1/-2

? = 1/2

Find the sum without using a number line. -8 1/6+2

Alina [70]

Answer:

Hi there!

Your answer is:

-35/6 OR -5 & 5/6

Step-by-step explanation:

-8 & 1/6

CHANGE TO IMPROPER FRACTION!

(-8*6 +1)/6

-48+1 / 6

-47 / 6

-47/6 + 2/1

CHANGE 2 SO IT HAS THE SAME DENOMINATOR

2/1 * 6/6

12/6

-47/6 + 12/6

-47+12

-35/6

Hope this helps

Use the distance formula to find the distance between the points given.

masha68 [24]

The distance between the points is $4\sqrt{13}$

Step-by-step explanation:

The formula of the distance between two points $(x_{1},y_{1})$ and

$(x_{2},y_{2})$ is $d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

To find the distance between two point:

Put one of the two point as $(x_{1},y_{1})$
Put the other point as $(x_{2},y_{2})$
Substitute then in the rule of the distance and calculate the distance

∵ The two points are (18 , -2) and (6 , -10)

- Put (18 , -2) as $(x_{1},y_{1})$ and (6 , -10) as $(x_{2},y_{2})$

∴ $x_{1}$ = 18 and $x_{2}$ = 6

∴ $y_{1}$ = -2 and $y_{2}$ = -10

- Substitute them in the rule below

∵ $d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

∴ $d=\sqrt{(6-18)^{2}+(-10--2)^{2}}$

∴ $d=\sqrt{(-12)^{2}+(-10+2)^{2}}$

∴ $d=\sqrt{(-12)^{2}+(-8)^{2}}$

∵ (-12)² = 144 and (-8)² = 64

∴ $d=\sqrt{144+64}$

∴ $d=\sqrt{208}$

∵ $\sqrt{208}=4\sqrt{13}$

∴ $d=4\sqrt{13}$

The distance between the points is $4\sqrt{13}$

Solve this with elimination please, 3x + 6y = 6

Dafna1 [17]

Times 2nd equation by 2
add to first equation

3x+6y=6
4x-6y=8 +
7x+0y=14

7x=14
divide both sides by 7
x=2

sub back

2x-3y=4
2(2)-3y=4
4-3y=4
minus 4 both sideds
-3y=0
y=0

(x,y)
(2,0)
