Answer:
Amplitude: 3
Period: 2π
Step-by-step explanation:
Y+x=98
y-x=22
I'm going to use elimination.
y+x=98
y-x=22
-----------
2y+0x=120 SIMPLIFY 2y=120 SIMPLIFY y=60.
Substitute that into either equation and you get y=60 and x=38
Have a nice day! :)
First one is y=4x and the second one is y=2x
Answer:
g
Step-by-step explanation:
The are formula for a triangle is (since a triangle is half a rectangle, and the area formula for a rectangle is b*h)
1/2 * b * h = area
Your equation would be:
1/2* 7.3 * 7 = area
=25.55
