Look into my attachment
in rhombus ABCD, ∠AOB = 90°
Look at ΔAOBthe sum of inner angles = 180°
∠BAO + ∠AOB + ∠ABO = 180°
2x + 1 + 90 + 2x + 5 = 180°
4x + 96 = 180
4x = 84
x = 21
y = −1/4x^2 + 4x − 19
1. Use x = -b/2a to find x.
x = -4/2(-1/4)
x = -4/(-1/2)
x = -4/1 • (-2/1)
x = 8/1
x = 8
2. Plug x into the function to find your vertex.
Replace every x you see in the function with 8 and do the math.
Take it from here.
A = 0.363636 ...
a = 0.(36)
100a = 36.(36)
100a - a = 36.(36) - 0.(36)
99a = 36
Answer:Joe is 25 and Susan is 16
Step-by-step explanation: First try random numbers and do (random number- 9). Next add that number to the random number.
My random number was 25. I subtracted nine and got 16 .Next I added those two numbers. I got 41.
