Answer:
Caras hourly wage is $10.08 after 3 years
Step-by-step explanation:
4% of 9
0.04 x 9 = 0.36
then you multiply 0.36 by 3 because you are solving for 3 years.
0.36 x 3 = 1.08
then you add 1.08 to 9 because Cara's wage goes up $1.08 in 3 years
1.08 + 9 = 10.08
answer:
Cara's hourly wage is $10.08 after 3 years of working
Answer: the system has no solution.
Step-by-step explanation:
\displaystyle\\
\left \{ {{x^2y=16\ \ \ \ \ (1)} \atop {x^2+4y+16=0\ \ \ \ \ (2)}} \right. .\\
Multiply\ both\ sides\ of\ the\ equation\ (2)\ by\ y\ (y\neq 0):\\
x^2y+4y^2+16y=0\\
We\ substitute\ equation\ (1)\ into\ equation\ (2):\\
16+4y^2+16y=0\\
4y^2+16y+16=0\\
4*(y^2+4y+4)=0\\
4*(y^2+2*y*2+2^2)=0\\
4*(y+2)^2=0\\
Divide\ both\ sides\ of\ the \ equation\ by\ 4:\\
(y+2)^2=0\\
(y+2)*(y+2)=0\\
So,\ y+2=0\\
y=-2.\\
