Answer:
Amount in 4% account: $550
Step-by-step explanation:
Use simple interest formula
where
I = interest
P = principal
r = rate (as decimal)
t = time.

then
![I_1=x\cdot 0.04\cdot 1=0.04x](https://tex.z-dn.net/?f=I_1%3Dx%5Ccdot%200.04%5Ccdot%201%3D0.04x)

then
![I_2=(1,500-x)\cdot 0.05\cdot 1=0.05(1,500-x)](https://tex.z-dn.net/?f=I_2%3D%281%2C500-x%29%5Ccdot%200.05%5Ccdot%201%3D0.05%281%2C500-x%29)
You have earned $69.50 in total, so

Answer:
one to one function
Step-by-step explanation:
f(x)=6x+1 can only be a one to one function when x1=x2
Now,
f(x1)=f(x2)
or, 6x1 + 1 = 6x2 + 1
or, 6x1 = 6x2
or, x1 = x2
So f(x)= 6x + 1 is a one to one function
The table of values of the function y = 2x^2 is:
x 0 1 2 3 4
y 0 2 8 18 32
<h3>How to complete the table?</h3>
The equation of the function is given as:
y = 2x^2
When x= 0, we have
y = 2 * 0^2 = 0
When x= 1, we have
y = 2 * 1^2 = 2
When x= 2, we have
y = 2 * 2^2 = 8
When x= 3, we have
y = 2 * 3^2 = 18
When x= 4, we have
y = 2 * 4^2 = 32
So, the table of values is:
x 0 1 2 3 4
y 0 2 8 18 32
