The following set of linear equations 2x+2y=18 x+3y=17
NemiM [27]

Answer:

x = 5

y = 4

Step-by-step explanation:

1. 2x + 2y = 18

2. x + 3y = 17

Multiply the first equation by 1 and the second equation by 2 to eliminate x

We have

2x + 2y = 18

2x + 6y = 34

Subtract equation 2 from equation 1

-4y = -16

Divide both sides by -4 to isolate y

-4y/-4 = -16/-4

y = 4

Now substitute 4 for y in either equation to get x. Using equation 2 we have

x + 3y = 17

x + 3 x 4 = 17

x + 12 = 17

Subtract 12 from both sides

x + 12 - 12 = 17 - 12

x = 5

x = 5 and

y = 4

I need help rlly bad I have no idea what’s the answer plsss help me!!!
lyudmila [28]

Answer:

n = 6\sqrt{3}

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin30° = \frac{\sqrt{3} }{2} , then

sin30° = \frac{opposite}{hypotenuse} = \frac{n}{12} = \frac{\sqrt{3} }{2} ( cross- multiply )

2n = 12\sqrt{3} ( divide both sides by 2 )

n = 6\sqrt{3}

In the standard (x, y) coordinate plane, what is the slope of the line joining the points (3,7) and (4,−8)?
rjkz [21]
We know that the slope formula is m = (y1 - y2)/(x1 - x2)
Your points are: (3, 7) and (4, -8)
In this case,
x1 = 3
x2 = 4
y1 = 7
y2 = -8
Now, just plug in the numbers:
m = (7 - -8)/(3-4)
m = 15/-1
m = -15
Your slope is -15.
