Step-by-step explanation:
Answer:

Step-by-step explanation:
Remember that


The speed is equal to divide the distance by the time
Convert the units


so


<h2>(x, y) = (21/13 , 84/13)</h2>
Step-by-step explanation:
x + 3y = 21
- 4x + y = 0
y = 4x
<h2>_____________</h2>
x + 3y = 21
x + 3(4x) = 21
x + 12x = 21
13x = 21
x = 21/13
y = 4x
y = 4 (21/13)
y = 84/13
(x, y) = (21/13 , 84/13)
Answer: Choice D
Explanation:
This is because all of the exponents are odd for this polynomial. It might help to think of that 4x as 4x^1.
Answer: y - x = 1
Step-by-step explanation: Note : for two lines to be parallel, then they have the same slope.
i.e the slope is 1
Using y - y1 = m ( x-x1) to find the equation of the line
⇒ y - 2 = 1 (x - 1)
y - 2 = x - 1
y - x = -1 +2
y - x = 1
it could also be written in slope intercept form as y = x + 1
