What is the function equation in function notation?

Mathematics
1 answer:
Yanka [14]3 years ago
5 0

Answer:

y= 2x +1

By direct comparison we can see that m =2 (slope) and b =1 (intercept)

Step-by-step explanation:

Assuming the following function:

y-2x =1

We want to find the following general equation for a linear model:

y = mx +b

On this case we just need to add 2x on both sides of the original equation and we got:

y= 2x +1

By direct comparison we can see that m =2 and b =1

mx + b = 2x +1

mx=2x , m =2

b =1

the value of m on this case represnt the slope and b the intercept.

The slope is defined by the following formula:

m =\frac{\Delta y}{\Delta x}

And is the interpretation is the rate of change of y respect to x, can be positive or negative. Or the increase/decrease of y when x increase 1 unit.

And the value b=1 represent the y intercept, that means if x=0 then y =1

Nancy and Karen went on a trip to the mountain. Nancy started her trip 30 minutes later than Karen. They started from the same p
Katyanochek1 [597]
Distance = (rate)(time)
In this problem, note that both girls traveled the same distance.

Karens distance = r * 1.5 hrs          we dont know her rate
Nancy distance = 50 * 1 hr              we know she started 30 min later
                                                         but arrived at the same time

since the distances are equal
r*1.5 = 50 * 1          all you have to do is solve for r

1.5r = 50
r = 50/1.5
r = 33 1/3 miles per hour

An airplane started at point K, travelled 560 miles to point L, adjusted its route and travelled another 575 miles to point M. I
S_A_V [24]

Answer:

Step-by-step explanation:

Using the cosine theorem:

c^{2} =a^{2} +b^{2} -abcos\beta

952^{2} =560^{2} +575^{2} -560*575cos\beta

\beta =cos^{-1} (\frac{560^{2}+575^{2}-952^{2}   }{2*560*575} )

The angle is 114.014 degrees if we substract 90 degrees it means that at point L the plane changed its angle by 24 degrees

What is the probability that a resident reports high satisfaction, given that the resident is a renter?
dem82 [27]

Answer:

The probability that a resident reports high satisfaction while the resident is a renter is Option(a) 13.7\%

Step-by-step explanation:

Given:

                               Levels of satisfaction

                      High      Medium     Low       Total

Owners          26             34               18           78

Renters           15            12                5            22

Total               41             46               23          110

The Resident is a renter.

Step 1:

To find the probability that a resident reports high satisfaction.

P(Renter- higher satisfaction)= Higher Satisfaction by render ÷ Total level of satisfaction

=\frac{15}{110}

=0.137

13.7\% is the probability that a resident reports high satisfaction.

Therefore, Option (a) is a correct answer.
