Y Solve this system of linear equations:
4x - 2y = 8

2.
Step 1: Plot the x-intercept of the first equation.
Step 2: Plot the y-intercept of the first equation.
Step 3: Plot the y-intercept of the second equation.
Step 4: Use the slope of the second equation to plot one
more point.

-2

Step 1: This is where the line touches the x axis: 2. Or substitute y=0 into equation  to get x

Step 2: This is where the line touches the y axis, -2

Step 3: Do the same for other

Step 4: Plug in 1 into x to get y

geometric series converge the common ratio r has magnitude less than one.

which is equivalent to

for the example we need

|2-x| < 1

-1 < 2-x   and 2-x < 1

x < 3 and x > 1

we can write that

answer: 1 < x < 3

1a. common ratio r=250/25=10 > 1     diverges

1b.   r=50/100=1/2 converges

when these converge they converge to

where a is the first term.

answer: 200

1c. r=-1   so it's not the case that |r| < 1.     diverges

2a. x is the common ratio so we converge when |x|< 1

2b.   r=-10x / -2 = 5x.

we converge when

|5x| < 1

|x| < 1/5

2c.   r=3-2x

-1 < 3-2x and 3-2x < 1

-4 < -2x and 2 < 2x

x < 2 and 1 < x

1 < x < 2

2d. [/tex] r=-48x^3/12 = 4x^3[/tex]

|4x^3| < 1

|x^3| < \frac 1 4

|x| < 4^{-1/3}

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844
