What is the rate of change in f(x)=12.17+0.23x

Step-by-step explanation:

the rate of change is also ur slope.

In y = mx + b formor f(x) = mx + b form, the slope (rate of change) can be found in the m position

f(x) = mx + b

f(x) = 0.23x + 12.17i rearranged a little

anyways, so ur slope (rate of change) is 0.23 <==

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
