Answer:
376 CM^2
I just took the test, so I hope this helps!
Step-by-step explanation:
Answer:
f(3) = -43
Step-by-step explanation:
alright so all you have to do is substitute x with 3 so it gonna look like
-(3)^2-9(3)-7= f(x)
now you just have to solve
-9-27-7=f(x)
f(x)= -43
Ok so BFD is a 90 degree angle. So you know you have 43 in one of the spaces so that means all you have to do is take 90 and minus 43 which is 47.
The first third and fourth boxes deserve check marks. Possibly the fifth.
Answer:
y = 5/2x - 5
Step-by-step explanation:
Step 1: Write equation
5x - 2y = 10
Step 2: Solve for <em>x</em>
- Subtract 5x on both sides: -2y = 10 - 5x
- Divide both sides by -2: y = -5 + 5/2x
- Rewrite: y = 5/2x - 5
