Hi there!

\large\boxed{\left \{ {{y=3x + 1} \atop {y = 3x - 1}} \right}

From the graph, we can see that both lines are parallel. We can determine the slope of one line to find the slope of the other.

Use the slope formula to determine the slope of a line. In this case, I am using the blue line as a reference:

\text{Slope } = \frac{ y_2 - y_1 } { x_2 - x_1 }

m = \frac{ 3 - 1 } { 1 - 0 } = 3

The slope of both lines is 3.

Let's find the equation of the blue line by finding its y-intercept to solve for the "b" value in the equation y= mx + b:

y-intercept is when x = 0, or at (0, 1). Therefore:

Blue line equation: y = 3x + 1

The red line intersects the y-axis at (0, -1), therefore:

Red line equation: y = 3x - 1

The systems of equations is:

y = 3x + 1

y = 3x - 1

Find the greatest common divisor (GCD) of 34255 and 203515.
seropon [69]
34255   = 5 * 13 * 17 * 31
203515 = 5 * 13 * 31 * 101

So GCD(34255, 203515) = 5 * 13 * 31 = 2015

A cylinder has a radius of 40 ft and a height of 17 ft. What is the exact surface area of the cylinder?
Georgia [21]

we know that

surface area of the cylinder=2*{area of the base}+perimeter of base*height

area of the base=pi*r²

r=40 ft

Area of base=pi*40²

Area of the base=1600*pi ft²


Perimeter of the base=2*pi*r

Perimeter of the base=2*pi*40

Perimeter of the base=80*pi ft


surface area of the cylinder=2*1600*pi+80*pi*17

surface area=4560*pi ft²


therefore

the answer is the option

4560π ft2
