If you work out the constants it says:
25+x²=100
Which simplifies to x=√75 or x=-√75
16 is the answer to this question.
X - John's shoe size
Two people in the family wear shoe size 6, but John's shoe size is not 6.
The shoe sizes in the family:
6, 6, x
The range is the difference between the highest and the lowest value. The range is 4.
There are two possibilities:
1. John's shoe size is the biggest:
However, his shoe size is not 10, so it's impossible.
2. John's shoe size is the smallest.
John's shoe size is 2.
The graph of linear equation 2x - 3y = -12 is as shown below.
I this question, we have been given a linear equation 2x - 3y = -12
We need to graph the points.
For x = 1,
2(1) - 3y = -12
2 - 3y = -12
-3y = -14
y = 14/3
For x = 0,
2(0) - 3y = -12
y = (-12)/(-3)
y = 4
For x = -1,
2(-1) - 3y = -12
-3y = -12 + 2
y = (-10) / (-3)
y = 10/3
So, we get coordinates (1, 14/3), (0, 4) and (-1, 10/3)
Now we plot these points.
The graph of linear equation 2x - 3y = -12 is as shown below.
