Answer:

y = 4x + 1

Step-by-step explanation:

y = mx + b

The line goes thru (0, 1) and (1, 5)

The slope = m = (5 - 1)/ 1 - 0) = 4/1 = 4

The y-intercept is (0, 1), so b = 1

y = 4x + 1 is the equation of the line

Answer:

V = 160mph

Step-by-step explanation:

We need to start from the formula of speed: V=d/t

We have two travels, with and against the wind, both done in the same time.

Clearing t from the formula, we will have: t=d/V2

450miles/V-35mph (speed of the wind is subtracted)

702miles/V+35mph (speed of the wind is subtracted)

Now, we find V:

450miles/V-35mph = 702miles/V+35

450*V+35 = 702*V-35

450V+15,750 = 702V-24,570

702V-450V = 15,750 + 24,570

252V = 40,320

V = 40,320/252

V = 160mph

What is the solution to w-11=1.3
trapecia [35]
<span>Simplifying w + -11 = 1.3
 
Reorder the terms: -11 + w = 1.3
 
Solving -11 + w = 1.3
 
Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '11' to each side of the equation. -11 + 11 + w = 1.3 + 11
 
Combine like terms: -11 + 11 = 0 0 + w = 1.3 + 11 w = 1.3 + 11
 
Combine like terms: 1.3 + 11 = 12.3 w = 12.3
 
Simplifying w = 12.3 <--- (Answer)
