Answer:
sure
Step-by-step explanation:
Answer:
-1 <x < 7
(-1,7)
Step-by-step explanation:
open circle on the left means the number is greater than
-1 <x
Open circle on the right means the number is less than
x < 7
Since both statements are true. we combine them
-1 <x < 7
open circles means parentheses, closed circles mean brackets
Answer:
y= 2/3x +1
Step-by-step explanation:
The y intercept is 1 It crosses the y axis at 1. So the point is (0,1)
Another point on the line is (3,3)
We can calculate the slope
m = (y2-y1)/(x2-x1)
= (3-1)/(3-0)
=2/3
The equation for a line is y=mx+b where m is the slope and b is the y intercept
y= 2/3x +1
Answer: 2a sqrt 15a
Explanation:
Sqrt 60a^3
= sqrt 4 x 15 x a^2 x a
= 2a sqrt 15a (because 4 and a^2 are a perfect square so we can drag it out of the square root)
