What is the rule for a line that has a slope of 2 and passes through ( 10,17 )

ella [17]

Answer:

Therefore the equation of the line has a slope 2 and passes through ( 10 , 17 ) is

2x - y = 3

Step-by-step explanation:

Given:

Slope = 2 = m ( say )

Let,

point A( x₁ , y₁) ≡ ( 10 , 17 )

To Find:

Equation of Line AB =?

Solution:

Equation of a line passing through a points A( x₁ , y₁) and having slope m is given by the formula,

$(y - y_{1} )=m\times(x-x_{1}) \\$

Substituting the given values in a above equation we get

$(y-17)=2\times (x-10)\\ \\(y-17)=2(x-10)\\\\y-17=2x-20\\2x-y=3\\2x-y=3...............\textrm{which is the required equation of the line AB}$

Therefore the equation of the line has a slope 2 and passes through ( 10 , 17 ) is

2x - y = 3

3/8 of the students in the class play have names that begin with M what fraction of the students in the play have names that do

mrs_skeptik [129]

Answer: 5/8

Please help!! i am super confused

erastovalidia [21]

Answer:

The train appears to go the same distance each minute

9mins

The cost for each person appears to be the same

Step-by-step explanation:

So for the first qu you basically want to find the distance the train travels each minute, so for

3mins : 9km

therefore

1min : 3km

basically divide 9 by 3

then the train travels 27km, how long does it take?

if 3km = 1min

then 27/3 = 9

so it takes the train 9 minutes

Then for the second qu you'll do the same thing

2ppl : $16

so one person : 16/2

so 1 person costs $8

so for 8 ppl you multiply 8 by 10

8ppl : $80

hope this helps:))))

If you apply for a job with Globo Corp, there is a 75% chance that you will get an interview.

aivan3 [116]

Answer:

The probability that you will get the job If you apply for a job with Globo Corp=0.36

Step-by-step explanation:

We are given that

If you apply for a job with Globo Corp, then the probability of getting interview P(A)=75%=0.75

If you get an interview, then the probability of getting job=P(B)=48%=0.48

We have to find the probability that you will get the job If you apply for a job with Globo Corp.

If you apply for a job with Globo Corp, the probability of getting job= $P(A)\times P(B)$

If you apply for a job with Globo Corp, the probability of getting job= $0.75\times 0.48$

If you apply for a job with Globo Corp, the probability of getting job=0.36

Hence, the probability that you will get the job If you apply for a job with Globo Corp=0.36
