X<2

Step-by-step explanation:

2x+4<8

subtract 4 from both sides

2x+4-4<8-4

simplify

2x<4

divide both by 2

2x/2<4/2

x<2

X+1 ^ 16 what is the coefficient of x^5

kirza4 [7]

Binomial theorem:

$(x+1)^{16}=\displaystyle\sum_{k=0}^{16}\dbinom{16}kx^{16-k}1^k=\sum_{k=0}^{16}\dbinom{16}kx^{16-k}$

The $x^5$ term corresponds with the term in the sum for which $16-k=5\implies k=11$ . For this $k$ , we get

$\dbinom{16}{11}x^{16-11}=\dbinom{16}{11}x^5$

So the coefficient you want to find is

$\dbinom{16}{11}=\dfrac{16!}{11!(16-11)!}=4368$

Which expression uses the associative property to make it easier to evaluate 14(3/2 . 1/4)

DaniilM [7]

Answer:

An easy way to do this problem is to follow PEMDAS if you don't know what that is it is P=() E I forgot M=Mutliply D=Division A=addition S=Sabtraction

But to do this problem first do the problem in the (3/2. 1/4) I hope this helps please reward brainlist.

14. Given: 5x + 4y = 24, x + 7y= 11; Prove: y= 1<br> Statements<br> reasons

Semenov [28]

Answer:

Step-by-step explanation:

We can use the process of elimination as

5x + 4y = 24

5(x + 7y = 11) —> 5x + 35y = 55

5x + 4y = 24

-(5x + 35y = 55)

—————————

-31y = -31

-31y/-31 = -31/-31

y=1

What is the slope of y= -7/5x +4

dem82 [27]

Y= -7/5x + 4

To find -intercept/zero, substitute

Multiply both sides of the equation by

0= -7/5x +4

Move the variable to the left-hand side and change its sign

0= -7x +20

Divide both sides of the equation by

7x=20
20/7 = 2 6/7 = x 2.857
