30 ft. tall. You must find the ratios and compare. 2/20=3/x The best way I know to do this is to cross multiply. 2 times x and 20 times 3. So, 2x= 60. Divide by 2 and you get x =30. The height of the tree would be 30 ft. You could also find the proportion. 20/2= 10, so the height,x, over 3 would be equal to 10. 3 times 10 is equal to 30.
Answer:
The slopes are neither perpendicular nor parallel.
Step-by-step explanation:
First we are going to find the slope-inercept form from the equation, -2x + 10y = 5.
Solve for y.
-2x + 10y = 5
<u>+2x. =</u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u>+2x</u>
10y = 2x + 5
So we now have
Looking at the equation above, the slopes are neither perpendicular nor parallel.

Answer:
What are the options?
Step-by-step explanation:
It says which one lol
Answer:
The answer would be -439
Step-by-step explanation:
To find this, start by finding t(-7)
t(x) = 3x
t(-7) = 3(-7)
t(-7) = -21
Now that we have this answer, we input it into the s(x) equation.
s(x) = 2 - x^2
s(-21) = 2 - (-21)^2
s(-21) = 2 - 441
s(-21) = -439
