When using the equation y=Mx+b you always graph b first
In this case, -1 is your b
Graph -1 on (0,-1)
2/7 is your slope
from (0,-1) you go up 2 and over 7.

At an archery competition, Jamie and Marshall's team tied Shawna and Wyatt's team for the top team score. Team scores are determ

strojnjashka [21]

Given:

Jamie and Marshall's team tied Shawna and Wyatt's team for the top team score.

Marshall scores 12 less than Jamie. Shawna scored twice as much as Marshall. Wyatt scored 4 less than Shawna.

To find:

The individual score of each person.

Solution:

Let x be the score of Jamie.

Marshall scores 12 less than Jamie.

Marshall score = x-12

Shawna scored twice as much as Marshall.

Shawna score = 2(x-12)

Wyatt scored 4 less than Shawna.

Wyatt score = 2(x-12)-4

Now,

Score of Jamie and Marshall's team $=x+(x-12)$

Score of Shawna and Wyatt's team $=2(x-12)+2(x-12)-4$

Jamie and Marshall's team tied Shawna and Wyatt's team

$x+(x-12)=2(x-12)+2(x-12)-4$

$x+x-12=2x-24+2x-24-4$

$2x-12=4x-52$

Isolate x.

$2x-4x=-52+12$

$-2x=-40$

Divide both sides by -2.

$x=\dfrac{-40}{-2}$

$x=20$

So, Jamie score = 20

Marshall score = 20-12

= 8

Shawna score = 2(20-12)

= 2(8)

= 16

Wyatt score = 2(20-12)-4

= 2(8)-4

= 16-4

= 12

Therefore, the scores of Jamie, Marshall, Shawna and Wyatt are 20, 8, 16 and 12 respectively.

How can one 1/4x − 3 = 1/2x + 8 be set up as a system of equations?

OleMash [197]

You can set y = to each side of the equation, then multiply by the denominator and put into standard form.

Left side:
.. y = 1/4x -3
.. 4y = x -12 . . . . multiply by 4
.. 4y -x = -12 . . . subtract x

Right side:
.. y = 1/2x +8
.. 2y = x +16 . . . multiply by 2
.. 2y -x = 16 . . . subtract x

These equations correspond to selection B.
