Answer:

- 1 = 16 + 3x - 1 \\ 3x = 16 - 1 + 1 \\  \frac{3x}{3} =  \frac{16}{3}  \\  x = 5.33

Cara started working for $9 per hour. She earns a 4% raise every year. What is her
shutvik [7]

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.\\

\displaystyle\\We\  substitute\  the\  value\  of\  y\  into\  equation\  (1):\\x^2*(-2)=16\\Divide\  both\  sides\  of\  the \ equation\  by\  -2:\\x^2=-8\\x^2\geq 0\\ Hence,\ the\ system\ has\ no\ solution.
