Answer:
$42
Step-by-step explanation:
35·0.20=7
tax is $7
35+7=42
the final price is $42
Look for what 'y' is when t = 1 and t = 2. Go to the graph, look at 1 on the bottom axis and go up till you find the point, then go all the way to the left to see what the y-value is, in this case it should be 1200. If you do the same with t = 2, you will get 2400. So our two ordered pairs are:
(1, 1200), (2, 2400)
We can find the slope of these two points by plugging them into the slope formula:

For points in the form of (x1, y1), (x2, y2). Plug in what we know:

Subtract:

Divide:

This is the slope, so we can write the equation:
Answer:
Your answer is 10
Step-by-step explanation:
160 devided by 16 = 10
To easily find the slope from standard form (Ax + By = C) use -A/B
1. m = -5/3
2. m = -3/5
perpendicular slopes are negative reciprocals, which these are not
parallel slopes are exactly the same, which these are also not
so, these equations are neither parallel nor perpendicular
