Every angle of a square equals 90 degrees.

2x - 4 = 90              3y + 6 = 90
2x = 90 + 4              3y = 90 - 6
2x = 94                    3y = 84
x = 94/2                     y = 84/3
x = 47                        y = 28

so x = 47 and y = 28

Answer:

B. x = 28, y = 47

Step-by-step explanation:

Given that PQRS is a square

We know that , In a square each vertex is a right angle that is 90 degree

So we set two equations

3y+ 6 = 90  and 2x -4 = 90

Solve for x  and y

3y  + 6 = 90

Subtract 6 from both sides

3y = 84

divide by 3 on both sides

y = 28

2x - 4 = 90

Add 4 on both sides

2x= 94

Divide by 2 on both sides

x= 47

Given the system of equations: 2x – y = –2 x = 14 2y
SSSSS [86.1K]
If you would like to solve the system of equations, you can do this using the following steps:

2x - y = -2
x = 14 + 2y
__________
<span>2x - y = -2
</span>2 * (14 + 2y) - y = -2
28 + 4y - y = -2
28 + 3y = -2
3y = -2 - 28
3y = -30    /3
y = -30/3
y = -10

<span>x = 14 + 2y = 14 + 2 * (-10) = 14 - 20 = -6
</span>
(x, y) = (-6, -10)

The correct result would be <span>(-6, -10).</span>

Ber [7]

Answer:

N is (8,5)

Step-by-step explanation:

Find the difference between M, and A, then add it to the M coordinates

The difference between M (x) and A (x) is 3, so you have to add 3 to M's x coordinate to get the N's x coordinate.

Do the same for the y coords and you will get (8,5)

Assume that x has a normal distribution with the specified mean and standard deviation. Find the indicated probability. (Round y
tino4ka555 [31]

Answer:

0.8762 or 87.62%

Step-by-step explanation:

Since our mean is μ=14.3 and our standard deviation is σ=3.7.  If we're trying to figure out what percentage is P(10 ≤ x ≤ 26) equal to we must first calculate our z values as such:

z=\frac{x-\mu}{\sigma}

Our x value ranges from 10 to 26 therefore let x=10 and we obtain:

z=\frac{10-14.3}{3.7} =-1.16\\

If we look at our z-table we find that the probability associated with a z value of -1.16 is 0.1230 meaning 12.30%.

Now let's calculate the z value when x = 26 and so:

z=\frac{26-14.3}{3.7}=3.16\\

Similarly, we use the z-table again and find that the probability associated with a z value of 3.16 is 0.9992 meaning 99.92%.

Now we want to find the probability in between 10 and 26 so we will now subtract the upper limit minus the lower limit in P(10 ≤ x ≤ 26) therefore:

0.9992 - 0.1230 = 0.8762

or 87.62%
