Answer:
₂₁C₉ = 293930
Step-by-step explanation:
9 members out of 21 senators will be selected on the subcommittee on Economy Policy
So we are in case of combinations of 21 people in groups of 9
₂₁C₉ =21! /( (21-9)!) *9! ⇒21*20*19*18*17*16+15*14*13*12! /(21-9)! *9!
=21*20*19*18*17*16*15*14*13/ 9! ⇒ = 19*2*17*15*14*13/6 ⇒ =293930
Answer:
y = -3/2x - 3
Step-by-step explanation:

y = -3/2x + b
Step 2: Find y-intercept <em>b</em>
3 = -3/2(-4) + b
3 = 6 + b
b = -3
Step 3: Rewrite linear equation
y = -3/2x - 3
Answer:
Both of them would just stay how they are
Step-by-step explanation:
Unless the x and y have a value that you have shown it would just stay at the same standard so there is not answer also no answer would be added.
