We need to find x and y for these system of equations. We will be using elimination for this.
Let's multiply the first equation by -5 and the second by 9. We will be eliminating x.
-45x-25y=-140
45x+81y=504
56y=364
Let's get y alone by dividing.
364÷56=6.5=y
Let's plug 6.5 in as y for the first equation.
9x+5(6.5)=28
9x+32.5=28
9x=-4.5÷9
X=-0.5
Now, let's try the set in the second equation.
5(-0.5)+9(6.5)
-2.5+58.5
56
So, the solution is X=-0.5 and Y=6.5.

Anvisha [2.4K]

Answer:

A.) median; 1.5

Step-by-step explanation:

Hello!

The median is the number that is in the middle when the numbers are listed from least to greatest

0, 0, 1, 1, 2, 2, 2, 14

We can take one from both sides till there are one or two numbers left

0, 1, 1, 2, 2, 2

1, 1, 2, 2

1, 2

If there are two numbers left we add them then divide by 2 to get the median

1 + 2 = 3

3 / 2 = 1.5

The answer is A.) median; 1.5

Hope this helps!

What is the slope of y=4-6x
julia-pushkina [17]

Answer:

the slope, m, is -6

Step-by-step explanation:

One of the most commonly used equations for a straight line is y = mx + b, where m is the slope and b is the y-intercept.

Comparing  y=4-6x to y = b + mx, we see that the slope, m, is -6 and the y-intercept, b, is 4.
