Answer:

120 ways

Step-by-step explanation:

To solve the question above, we use combination formula:

Where ;

nCr = n! / (n-r)! r!

10C7 = 10! / (10 - 7)! 7!

10C7 = 10! / 3! 7!

10C7 = (10 * 9 * 8) / 3 * 2 * 1

10C7 = 720 / 6

= 120 ways

Please help me with this math problem, urgent please

Answer:

y = -3.5x + 15

Step-by-step explanation:

Your slope-intercept equation is always y = mx + b

Using this formula, we need to find slope first: m = (y2-y1) / (x2-x1)

Step 1: Find slope

m = (1-8) / (4-2)

m = -7/2

Step 2: Plug in into slope-intercept form

y = -3.5x + b

Step 3: Find <em>b </em>(Plug in a coordinate given)

1 = -3.5(4) + b

1 = -14 + b

b = 15

Step 4: Combine it all together

y = -3.5x + 15

And you have your final answer.
