Equations are given,
y= x+2
<span>
y= -4x+7
As you can see both the expressions, x+2 and -4x+7 are equal to "y". That means they are equal to each other too.
So let's equal them and solve it.

Now we have x's value we will plug it in the first equation to find "y".

Hello!
The mean is the average. To calculate it you add up all the numbers, and divide by how many numbers there were. So for example, if you had 1 and 3, you would add them and divide by two since there were two numbers. We will calculate the mean of this data set below.
(11+21+16+7+10)=65
65/5=13
The mean of the data set is 13.
---------------------------------------------------------------------------------------
Now we need to find the median. To do so we have to first order all of the numbers from least to greatest.
7,10,11,16,21
Now we have to find the number in the middle of the data set.
11 is our median. (Note that when calculating the median with an even number of data points, you will find the mean of the two center numbers)
I hope this helps!
Answer: 5x+12.50=62.50
5*12.50=62.50
Step-by-step explanation:
(2x - 1)(6x - 7)
2x(6x - 7) - 1(6x - 7)
2x(6x) - 2x(7) - 1(6x) + 1(7)
12x² - 14x - 6x + 7
12x² - 20x + 7
