PLZ HELP!! 20 points!

To find if a point is a solution to a system of equations, we need to plug in the x and y values of the point into each equation, and see if the equation is true.

Let's plug it into the first equation first:

-2(3) - 4(-2) might = 2
-6 + 8 = 2

The first equation is true. 

Now, we need to check the second equation:

3(3) + 4(-2) might =8
9 - 8 does not = 8

Therefore, even if the point satisfies one equation, it does not satisfy the other. We can conclude that this is not a solution. 

Hope this helps!

If QRST is a rectangle with QT = 30 and RS = 4x + 10, find x.
ArbitrLikvidat [17]
The opposite side pairs in a rectangle are congruent, so basically QT would be congruent to RS when you draw the rectangle and label the points.
4x+10=30
4x=20

You roll a pair of six-sided number cubes, numbered 1 through 6. What is the probability of rolling two odd numbers? (Enter your
lbvjy [14]

Answer:

1/4 or 25%

Step-by-step explanation:

The probability for rolling an odd number is 50% or  \frac{1}{2} because there are 3 odd numbers, (1, 3, 5) and 6 total outcomes (1, 2, 3, 4, 5, 6). \frac{3}{6} =\frac{1}{2}

The probability for rolling two odd numbers in a row is

\frac{1}{2} *\frac{1}{2} =\frac{1}{4}

So, the probability of rolling an odd number twice is 25% or  \frac{1}{4}.

I will mark brainliest, please help !!
Elena L [17]

Answer:

x = 5/(a-b+3)

Step-by-step explanation:

ax+3x=bx+5

Collect all the terms that has x:

ax-bx+3x = 5 (Subtracting bx both sides)

Take out the x!

x(a-b+3) =5

Divide (a-b+3) both sides to solve for x

x = 5/(a-b+3)

Hope this helps!
