Answer:
6 minutes
Step-by-step explanation:
every minute is 120
720/120=6
→ a
the equation is y = mx ( where m is the slope / constant of variation )
calculate m using the gradient formula
m = ( y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁) = (0, 0 ) and (x₂, y₂ ) = (4, 1) ← 2 points on the line
m =
= 
Hi there!
To find this you can simply use a calculator. All you have to do is divide the numerator by the denominator to see what you get.
7/200 in decimal form is 0.035. Pretty simple.
This fraction cannot be simplified.
Hope this helps!
The piecewise function all the way to the left (x + 3) should have an ending point shaded in. [At x = -2] The next function ((x^2) -1) should have both ending points left unshaded. Finally, the logarithm function should have a shaded in starting point [At x = 1] and should have an unshaded ending point at x = 3.
