Answer:
gradient m = - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the gradient and c the y- intercept )
y = - x - 3 ← is in slope- intercept form
with gradient m = - 1
The equation to use here is 3^x = 81. You could start to try numbers, and you would realize that x = 4 weeks.
You can set these equal to each other. The numerator is how many free throws Shawn makes and the denominator is total free throws. You can cross multiply and solve for x but it’s way easier to just see that 11*2 = 22 and then multiply 7*2 to get x which is 14. Hope this helped!
There are 18 different possible values for N.
Explanation: 180=2x2x3x3x5
Therefore there are 3x3x2 possibilities.
