Answer: 90 degrees Celsius
Step-by-step explanation:
120-30 = 90
I hope this helps. If I need to know explain further let me know.
Answer:
Step-by-step explanation:
We know all angles in a circle or around a point is 360°
So using that we can make the equation:
the angles e and f are on a straight line so they add up to 180°
So the other side of the line will be 180 as well. Hence we can make the equation:
Answer:
(x-3)^2
Step-by-step explanation:
y = sqrt(x) +3
To find the inverse , we exchange x and y and then solve for y
Exchange x and y
x = sqrt(y) +3
Now solve for y
Subtract 3 from each side
x-3 = sqrt(y)
Square each side
(x-3)^2 = (sqrt(y))^2
(x-3)^2 = y
The inverse of sqrt(x) +3 is (x-3)^2
Step-by-step explanation:
y = -5x - 1 should be your function.
Check. Plug in the x to get the desired y
9 = -5(-2) - 1
9 = 10 - 1
9 = 9 (correct)
4 = -5(-1) - 1
4 = 5 - 1
4 = 4 (correct)
-1 = -5(0) - 1
-1 = 0 - 1
-1 = -1 (correct)
etc.
