Determine if the following system of equations has no solutions, infinitely many solutions or exactly one solution.

34kurt

Answer:

Infinitely many solutions

Step-by-step explanation:

First, let's organize the equations of the lines into slope-intercept form.

x + 4y = 1
=> 4y = -x + 1
=> y = -x/4 + 1/4

And,

2x + 8y = 2
=> 8y = -2x + 2
=> y = -2x/8 + 2/8
=> y = -x/4 + 1/4

Since both the graphs are the same, the two equations have infinitely many solutions.

Since 1995 the cost of a bag of groceries has increased about 2.5% each year. The equation C = 25(1.025)x will give the value of

Marianna [84]

Answer: 28 years

Step-by-step explanation:

Given

The equation showing the value of the bag after x years is $C=25(1.025)^x$

If the price of the bag increased by 2.5%, from the equation, we can deduce that

Initial cost of the bag is 25

Double of the initial value is 50

Insert it in the equation

$\Rightarrow 50=25(1.025)^x\\\Rightarrow 2=1.025^x\\\text{Taking natural log}\\\Rightarrow \ln 2=x\ln (1.025)\\\\\Rightarrow x=\dfrac{\ln 2}{\ln 1.025}\\\\\Rightarrow x=28.07\approx 28$

It will take 28 years
