Answer:
Step-by-step explanation:
(x-3)/(x+4) = x/(x+10)
(x-3)(x+10) = x(x+4)
x²+7x-30 = x²+4x
3x = 30
x = 10
Answer:
Step-by-step explanation:
In the equation y=kx+1, k is the slope and 1 is the y-intercept.
To find the slope, use the formula k=y2-y1/x2-x1. To use this formula, you need two points. The first point, point M, is given to you. The second point can be the y-intercept, point (0, 1). Now, apply the formula to find the slope: k=3-1/1-0
k=2/1
k=2
We now have the equation y=2x+1.
The next step is to graph the line.
First, graph the y-intercept. Should look something like this: (star represents point. the point is on (0, 1).)

Then, use the slope to find your second point: (the point is on (1, 3)).

Draw a line through those two points and you have your answer!
Circumference = PI x Diameter
circumference of tire = 3.14 x 1.1 = 3.454 feet
so every full turn of the tire the bike travels 3.454 feet
110 feet / 3.454 = 31.8 turns
Answer:
points are( 6,2),(7,5) and (3,8)
Step-by-step explanation:
X,y changes into y,-X
