Not sure if you still need this but the answer is 17/19.
Answer:
C
Step-by-step explanation:
4 : 9
2 : 4.5
y = kx
y = 2.25x
Y+Y+30=90
2Y=60 /:2
Y=30
PNQ=30°
QNO=30+30=60°
Answer:y=-1/2
Step-by-step explanation:
125=(1/25)^(y-1)
5^3=(5^(-2))^(y-1)
5^3=5^(-2(y-1))
The same base eliminate each other we then have
3=-2(y-1)
3=-2y+2
Collect like terms
2y=2-3
2y=-1
Divide both sides by 2
2y/2=-1/2
y=-1/2
