your missing some number to do the process
the first question you add all the sides
let the speed of plane in still air be x and that wind be y
therefore:
x+y=490
x-y=390
next we solve for the values of x and y, first we add the above equations. This will give us:
2x=880
x=880/2
x=440 miles per hour.
substituting the value of x in one of the equations and solving for y we get:
440+y=490
y=490-440
y=50 miles per hour
Answer:
y-int: (0, 13)
Equation: y = -2x + 13
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
<em>m</em> = slope
<em>b</em> = y-intercept
Step 1: Define variables
<em>m</em> = -2
Random point (5, 3)
Step 2: Plug in known variables
y = -2x + b
Step 3: Find y-intercept <em>b</em>
3 = -2(5) + b
3 = -10 + b
b = 13
Step 4: Rewrite equation
y = -2x + 13
Yes I agree I don’t have a good night I have no idea what I am doing lol I just don’t have a problem I don’t
