68°
Step-by-step explanation:
arctan(x) = 5/2
Answer:
(-5,5)
Step-by-step explanation:
So first off, if you are going left by 9. That means you will going back (aka negative 9 points).Also, since you are going left, only the x axis changes because left or right is what changes here.
Once you count back 9 spaces, or do 4-9, you will end up with negative 5(x value)
Your ending product is (-5,5)
hope this helps!!
Answer:
He is 40
Step-by-step explanation:
She is 10. In 30 years she will be 40. In 30 years, he will be 70. he is 40 add 30 years then he will be 70.
Use the 2 points and use the formula
![\frac{y2 - y1}{x2 - x1}](https://tex.z-dn.net/?f=%20%5Cfrac%7By2%20-%20y1%7D%7Bx2%20-%20x1%7D%20)
to get slope
![\frac{3 - 1}{0 - 1}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%20-%201%7D%7B0%20-%201%7D%20)
and you get a slope of -2
for the second question its non of the above? i think the x intercept is 0.6666. if you're talking about y intercept then its -5
