Missing Rates

100

Fill in the missing values: 

100, ____, 80, 70

90

200

Fill in the missing value:

5.5, 6, _____, 7

6.5

300

Use y=mx+b to find the missing rate

If the slope is 5, term number x=3, and starting value b = 4, what is the term value (y)?

y=19

400

Use y=mx+b to find the missing rate

If the value of y=10, slope of 2, and term number x=3, what is the starting value (b)?

b =4

500

Use y=mx+b to find the missing rate

If the term value is 20, the slope is 3, and the starting value is -1, what is the term number (x)?

x = 7

Using the Equation

100

Using the equation y = 2x-4,

y when x=6

y=8

200

Using the equation y = 3x-4,

y when x=8

y= 20

300

Using the equation y = 2x-4,

y when x= -4

y = -12

400

Using the equation y = 5x-2,

x when y = 23

x=5

500

Using the equation y = -2x+2,

x when y = 44

x = -21

Random

100

Solve this equation:

15 = 3n -6

15 = 3n -6

15+6=3n

21=3n

7=n

200

Rewrite 5 x 5 x 5 x 5 x 5 x 5 in exponential notation

5⁶

300

Check if this point (4,10) is on the line y = 3x -2

Yes,

10 = 3(4)-2

10=12-2

10=10

400

Which pattern increases faster?

Pattern A: +5 per step

Pattern B: +11 per every 2 steps

Pattern B is +5.5 every step

500

Calculate the slope between these two points

(1,4) and (4,10)

= 10-4/4-1

= 6/3

= 2
