Assuming the function is x^2
Answer:
<h2>Jimmy is 16 old.</h2>
Step-by-step explanation:
J - the age of Jimmy John
50 - the age of Papa John
3J + 2 - the age of Papa John
The euaqtion:
3J + 2 = 50 <em>subtract 2 from both sides</em>
3J + 2 - 2 = 50 - 2
3J = 48 <em>divide both sides by 3</em>
3J/3 = 48/3
J = 16
Answer:
Option (4)
Step-by-step explanation:
Let x = ![\sqrt[4]{7}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B7%7D)
![\sqrt[4]{7}\times \sqrt[4]{7}\times \sqrt[4]{7}\times \sqrt[4]{7}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B7%7D%5Ctimes%20%5Csqrt%5B4%5D%7B7%7D%5Ctimes%20%5Csqrt%5B4%5D%7B7%7D%5Ctimes%20%5Csqrt%5B4%5D%7B7%7D)
= (x)(x)(x)(x)
= 
= x⁴
Now we substitute the value x =
x⁴ = ![(\sqrt[4]{7})^4](https://tex.z-dn.net/?f=%28%5Csqrt%5B4%5D%7B7%7D%29%5E4)
x⁴ = 7
Therefore, Option (4) will be the answer.
Answer:
B. $8
Step-by-step explanation:
Given:
Total payment, T = $160
Hourly rates = $t/hour
= total payment/total time worked
The question said, "worked 12 more hours than the amount she is paid per hour".
Total time worked = (12 + t) hour
Therefore, Hourly rates of payment, t = 160/(12 + t)
t^2 + 12t - 160 = 0
Solving the above quadratic equation,
t = -20 and 8
t = $8
Just multiply the expression by 4.
