This question involves mathematical combinations. The formula is:
nCr = n!/r!(n - r)!
Substituting the values:
7C6 = 7!/6!(7 - 6)!
= (7 x 6 x 5 x 4 x 3 x 2 x 1)/(6 x 5 x 4 x 3 x 2 x 1)(1)
= 7
The answer is D

Which graph represents the function y = 3*+2?
puteri [66]

Answer:

We can graph y = 2x/3 - 2 to find the line.

We know one point, which is the y-intercept. The y-intercept is (0,-2) so that is our first point. Plot that point on the chart. Now to find another point, we can just insert a number for x and solve for y. I am going to use the number 3.

y = 2x/3 - 2

y = 2(3)/3 - 2

y = 6/3 - 2

y = 2 - 2

y = 0

So when x = 3 y = 0. We have another point,which is (3,0) Plot the points (0, -2) (3, 0) and draw a line between the points and that is your graph.

there ya go

Write the first four terms in the following sequences. A(n+1)=A(n)−5 for n≥1 and A(1)=9 .
luda_lava [24]

Answer:

Step-by-step explanation:

A(1) = 9

A(n+1) = A(n) - 5

n = 1 ;     A(1+1) = A(1) - 5

             A(2) =  9 - 5

             A(2) = 4

n = 2 ;     A(2+1) = A(2) - 5

             A(3) =  4 - 5

             A(3) = 1

n = 3 ;     A(3+1) = A(3) - 5

             A(4) =  1 - 5

             A(4) = -4

n = 4 ;     A(4+1) = A(4) - 5

             A(5) =  -4 - 5

             A(5) = -9

First four terms are: 9 , 4 , 1 , -4 , - 9
