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.

What happens to the value of the expression 80-2r as r decreases?
Ghella [55]

Answer:The value of the expression increases as r decreases.

Step-by-step explanation:

To find : What happens to the value of the expression as r decreases?

Given Expression: 80-2r

We check for different value of r as decreasing order,

r        80-2r

5        80-10=70

4        80-8=72

3        80-6=74

2        80-4=76

1         80-2=78

As r decreases the value of expression increases.

Therefore, the value of the expression increases as r decreases.

Hope this helps!
