X/7 = 0.4 => x = 7 x 0.4 = 2.8
7/y = 0.4 => y = 7 : 0.4 = 17.5
Answer:
x = all real numbers
infinite solutions
Step-by-step explanation:
6x+12=2(3x+6)
Distribute
6x+12 = 6x+12
Subtract 6x from each side
12 =12
This is always true
This means there are infinite solutions for x
x is all real numbers
The median average refers to number in the middle of the set. But we need to write it in chronological order.
Now the set becomes 57, 60, 62, 65.
Now find the number in the middle. In this case, it both 60 and 62.
But we need one number.
So, we will take the average of both of them.
60 + 62 = 122
122 / 2 = 61
So, 61 is the median of the set.

Answer:
Slope = -2
Step-by-step explanation:
x1 y1 x2 y2
(-1 , 9) (2 , 3)
Slope = <u>y2 - y1</u>
x2 - x1
<u>3 - 9 </u>= <u> -6 </u>
2 -(-1) = 3
= -2
