“x” represents an undefined term
ex: 9x-2
Please give brainliest :)
Answer:
10
Step-by-step explanation:
This expression uses the idea of exponential edition. The basis is, when you have the same base number being multiplied, you can add the exponentials.
Consider the case of 2 * 2. We know this to be 4. When writing 2 * 2, you can write this as 2^1 * 2^1 == 2^(1+1) == 2^2 == 4. See how we added the powers to get the new exponential?
We will apply this same idea here.
10^(1/2) * 10^(1/2) == 10^(1/2 + 1/2) == 10^(1) == 10.
So, the simplified expression is 10.
Cheers.
Answer:
y = x-2
Step-by-step explanation:
Pick two points on the line
(0,-2) and (2,0)
We can find the slope
m = (y2-y1)/(x2-x1)
= (0--2)/(2-0)
= (0+2)/(2-0)
2/2
=
We know the y intercept is -2 ( where it crosses the y axis)
y = mx +b is the slope intercept form of the equation where m is the slope and b is the y intercept
y = 1x -2
y = x-2
Assuming two weeks is 14 days
3/7*14=6
therefore it was sunny for 6 days
