Solve the system of linear equations using either substitution or the elimination method.

Lelechka [254]

Answer:

x=2;y=2

Step-by-step explanation:

2x+y=6..........1

3x-y=4............2

adding equation1 with equation 2

2x+y+3x-y=6+4

5x=10

x=10/5=2

substituting vslue of y in equation 1

2×2+y=6

y=6-4

y=2

What 2 numbers have a difference in 54

nata0808 [166]

Hey! :)

Let us make these number be x and y.

x + y = 54

x - y = 26

Now, add these equations to get the following:

2x = 54 + 26 = 80

2x = 80

x = 80/2 = 40

Now, x + y = 54 meaning 40 + y = 54.

Therefore y = 54 - 40 = 14.

Have a great rest of your day :)

The coordinates of point S are (8.4). What are the

Lerok [7]

Answer:

Co-ordinates of point R is (26,2)

Step-by-step explanation:

Given point:

Endpoint S(8,4)

Mid-point M of segment RS (17,3)

Let endpoint $R$ have co-ordinates $(x_2,y_2)$

Using midpoint formula:

$M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

Where $(x_1,y_1)$ and $(x_2,y_2)$ are co-ordinates of the endpoint of the segment.

Plugging in values to find the midpoint of segment KN.

$M=(\frac{8+x_2}{2},\frac{4+y_2}{2})$

We know $M(17,3)$

So, we have

$(17,3)=(\frac{8+x_2}{2},\frac{4+y_2}{2})$

Solving for $x_2$

$\frac{8+x_2}{2}=17$

Multiplying both sides by 2.

$\frac{8+x_2}{2}\times 2=17\times 2$

$8+x_2=34$

Subtracting both sides by 8.

$8+x_2-8=34-8$

∴ $x_2=26$

Solving for $y_2$

$\frac{4+y_2}{2}=3$

Multiplying both sides by 2.

$\frac{4+y_2}{2}\times 2=3\times 2$

$4+y_2=6$

Subtracting both sides by 4.

$4+y_2-4=6-4$

∴ $y_2=2$

Thus co-ordinates of point R is (26,2) (Answer)

Pls help and I will mark u as brainliest PLSSSSS anyone plss

This is a SOH-CAH-TOA problem, or trigonometry! Take a look at the attached image for a sketch of this problem.

(a) To find the distance up the wall, we'll need to use the sine function. This is because we know the angle is opposite the wall and we also know the hypotenuse.

sin(58.5) = x/4

x = (4)(sin(58.5)) ---> Plug this into your calculator to get the answer! And make sure your calculator is in degrees if that is an option.

x = 3.4 meters

(b) To find the distance between the foot of the ladder and the wall, we'll need to use the cosine function. This is because we know the angle is adjacent to the wall and we also know the hypotenuse.

cos(58.5) = x/4

x = (4)(cos(58.5))

x = 2.1 meters

Hope this helps!! :)
