Answer:

y= 2x

Step-by-step explanation:

(0,0) and (2, 4)

m= (y2-y1)/ (x2-x1)

m= (4-0)/(2-0)

m= 4/2

m=2

y- y1= m(x -x1)

y - 4= 2(x - 2)

y-4= 2x - 4

y= 2x

Answer:

Step-by-step explanation:

y=mx+b where m is the slope and b is the y intercept. Since there is point (0,0) we know that b=0 so we only need to find m

m=(y2-y1)/(x2-x1)

m=(4-0)/(2-0)=4/2=2 so the line is

y=2x

There are 250 votes tallied in a school election with 3 candidate:A, Candidate B, and Candidate C. If 150 of the votes are for c

Tanya [424]

The answer is 75 and here's why.

Let's figure out the amount of remaining votes to prove this.

250 total votes - 150 votes for candidate a = 100 votes.

minus ↑ sign

Candidate B received 25% of the votes, so let's find 25% of 100

100 * 0.25 = 25 votes

Candidate B only got 25 votes (that's kinda sad, poor guy)

100 - 25 votes = the # of votes candidate C got

Candidate C got 75 votes!

5. Solve v = w - 20 for w.

slava [35]

v = w - 20

move -20 to the other side

sign changes from -20 to +20

to get w by itself

v+20= w-20+20

Answer:

w= v+20 or w= 20+v

Solve the following system of equations by the substitution method.

Dahasolnce [82]

Answer:

Step-by-step explanation:

5x=y+6 --------- equ 1

2x-3y=4 -------- equ 2

5x - 6 = y

y = 5x - 6

substitute in equ 2

2x-3(5x - 6) =4

2x - 3*5x + 3*6 = 4

2x - 15x + 18 = 4

- 13x = 4 - 18

-13x = -14

x = -14/-13

x = 14/13

substitute in equ 1

5*14/13 = y+6

70/13 - 6 = y

y = ( 70 - 78)/13

y = -8/13

The coordinates of the 3 of the vértices of a parallelogram are (-7, 3), (-6, 1), and (-4, 5). What is the equation for the line

Natali [406]

We know, opposite sides are parallelogram is parallel, therefore slopes are equal.

Slope of line one :

$m=\dfrac{-7-(-6)}{3-1}\\\\m =\dfrac{-1}{2}\\\\m= -0.5$

So, equation of other line passing through (-4,5) and have slope of -0.5 is :

y-5 = -0.5( x-(-4))

y-5 = -0.5x - 2

y + 1/2x = 3

2y + x = 6

Therefore, equation of line containing the (-4, 5) is 2y + x = 6.

Hence, this is the required solution.
