F(-5) = -5^2 - 2*(-5) - 7 = 25 - (-10) - 7 = 25 + 10 - 7 = 25 + 3 = 28
Answer:
42 degrees
Step-by-step explanation:
92 - 50 = x
42 degrees = x
I would say read it well and then write down an equation or expression to represent the data so its easier for you to understand and/or solve.
Step-by-step explanation:
Use the Pythagorean Theorem: a^2+b^2=c^2
We can set up the equation like this: 11^2+y^2=61^2
= 121+y^2=3,721
=y^2=3600
= y = 60
Just go ahead and subtract 3/4x and bring it to the other side so it should look like this -2y=5-3/4x then go ahead and divide with negative two
