The seventh term of the sequence -2, -6, -10, -14, ... is _____. -26 -24 -22 -20

Answers

We'll it keeps on subtracting by 4 to get each number.

-2,-6,-10,-14,-18,-22,-26.

Negative 26 is your answer. Hope this helped!

Answer:

-26

Step-by-step explanation:

We are counting by 4s

1) 2 - 4 = -2

2) -2 - 4 = -6

3) -6 - 4 = -10

4) -10 - 4 = -14

5) -14 - 4 = -18

6) -18 - 4 = -22

7) -22 - 4 = -26

The answer is C. 250.80

change the percent to a decimal (0.20) and multiply 1,254x0.20=250.80

Consider the leading term of the polynomial function. What is the end behavior of the graph?4x5 + 1x
a)Since n is odd and a is positive, the end behavior is up and down.
b)Since n is odd and a is positive, the end behavior is down and up.
c)Since n is odd and a is positive, the end behavior is down and down.
d)Since n is odd and a is positive, the end behavior is up and up.

Answers

odd functions go up and down in the ends
even function either go up on both ends or down on both end ,

so i think the answer would be :
since n is odd and a is positive , the end behavior is up and down

hope this helps

Answer: Since n is odd and a is positive, the end behavior is down and up.

Find the Quotient. y9 divided by y3

find the quotient. 2^3 divided by 5^2

Answers

Step-by-step explanation:

y9 divided by y3

(y^9)/(y^3)

When the base of the exponent are same and they are in division then we subtract the exponents.

(y^9)/(y^3)=y^(9-3)=y^6

2^3 divided by 5^2

(2^3)/(5^2)

The exponents of base are not same, so we cannot subtract the exponents

2^3=8 , 5^2= 25

(8)/(25) = 0.32 is a decimal number
2^3/5^2= .32

I couldn't get it as exponential notation, but here is the final answer

y9/y3= y3

and these two, you just divide ad regular numbers and the insert the y

What is the probability of not drawing a green marble from a jar containing 7 red, 4 green, 3 white, and 9 blue marbles?

Answers

7+4+3+9
11+12
23

(23)/(23) - (4)/(23)

(23-4)/(23)

(19)/(23) chance

Answer:

Probability of not drawing a green marble is 19/23.

Step-by-step explanation:

A jar is containing 7 red, 3 white, and 9 blue marbles.

Then the probability to draw a green marble will be = Numbers of green marbles/ Total numbers of marbles of all colors

P(G) = 4/(7 + 4 + 3 + 9)

P(G) = 4/23

Now the probability of not drawing a green marble = 1 - probability of drawing a green ball

P = 1 - 4/23 = 19/23

Therefore answer is 19/23.

How many degrees is x?

Answers

Short Answer x = 66
Remark
2x is the supplement of a 48 degree angle.
Supplementary angles add up to 180°

Equation
48 + x + x = 180  Collect like terms

Solution
48 + 2x = 180      Subtract 48 from both sides.
2x = 180 - 48  
2x = 132              Divide by 2
x = 66 <<<<<<<  Answer                  
x+x+48°=180°
2x+48°=180°
x=(180°-48°)/2
=66°
