Step-by-step explanation:
Part A, Option 1 is a exponential function while option is a linear equation.
Part B, Let y=b*a^(x) be the function for option 1. At x=1, y=1100 and at x=2, y=1210. 1100=b*a and 1210=b*a^2. Dividing them both we get, b=1.1 and a=1000. y=1000*(1.1)^(x). For option 2, it's a linear equation with a function y(x)=1000+100x.
The 20 year difference would be immense. With option 1, Belinda will get $6727.5 whereas with option 2, they will end up with $3000
Answer:
Yes
Step-by-step explanation:
because if you add that and then you subtract that you get that answer
Hello,
xy+xz=100==>x(y+z)=100
x/5*(3y+3z)+10=3/5*(x(y+z))+10=3/5*100+10=70
Answer C
answer: how we supposed to do it?
Step-by-step explanation:
i don't even understand
Let that number be x.
"I multiply a number by four" Can be represented by 4x.
"Then I add one" means that to 4x, you added 1. So it's 4x + 1
"The answer is 33" So 4x + 1 = 33.
We need to solve for x.
4x + 1 = 33
First, subtract 1 from each side to have the variable on a side and the number on the other:
4x + 1 - 1 = 33 - 2
4x = 32
Divide both sides by 4 to get the variable x alone on a side and its value on the other side:
(4x)/4 = 32/4
x = 8
You can recheck your answer (very important):
4x = 8*4 = 32
4x + 1 = 32 + 1 = 33
The answer has been approved.
Hope this Helps! :)
