If b = the number of blue bikes, whtoh algebraic expression represents the
phrase below?
the sum of the number of blue bikes and the 9 red bikes
ОА. b+9
B. b•9
ОСІБ – 9
OD. b= 9

A: b + 9

Step-by-step explanation:

If it's the sum of two numbers it is addition, meaning that you add the number of blue bikes(b) to the number of red bikes(9).

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
