Answer:
This would be quad III
Step-by-step explanation:
Answer: y = 4
Step-by-step explanation:
To solve, we will isolate the y variable.
Given:
4(y + 4) = 32
Distribute the 4 with multiplication:
4y + 16 = 32
Subtract 16 from both sides of the equation:
4y = 16
Divide both sides of the equation by 4:
y = 4
Assuming that angles X and Z are the same as A and C, the Y angle must be 75 degrees. It's because the sum of all three angles in any triangle give us 180 degrees, so:
180 - 45 - 60 = 75 degrees
A(n) = –3 • 2⁽ⁿ⁻¹⁾
for n = 1 , A₁ = -3.(2)⁰ = -3
for n = 2 , A₂ = -3.(2)¹ = -6
for n = 3 , A₃ = -3.(2)² = -12
for n = 4 , A₄ = -3.(2)³ = -24
...........................................
for n = 8 , A₈ = -3.(2)⁷ = -384
Step-by-step explanation:
2x-y=8
x+y=20
------------
3x=28
×=28÷3=9.3
so
9.3+y=20
y=20-9.3
y=20.7
