Answer:
y+3 = 2(x-4)
Step-by-step explanation:
If we have a slope and a point, we can use the point slope form for an equation of a line
y -y1= m(x-x1)
where m is the slope and (x1,y1) is the point
y--3 = 2(x-4)
y+3 = 2(x-4)
Answer:

Step-by-step explanation:
Given
P(A or B)= P(B)-P(A and B)
P(A)=1/3
P(A and B)=1/8
P(A or B)= 3/4
Required
Find P(B)
To find P(B), all we need to do is to substitute values of P(A or B) and P(A and B) in the given equation.
This goes thus;
P(A or B) = P(B) - P(A and B) becomes

Make P(B) the subject of formula

Take L.C.M

Add fractions

From the workings above, the value of P(B) using the given equation is 
Definition of a rational number:
A rational number is a number that can be written as fraction of integers.
19/10 is a fraction.
19 and 10 are integers.
19/10 follows exactly the definition of a rational number, so it is rational.
Answer:
they all equal 22 and then add the varible next to it
Step-by-step explanation:
M=3
You would begin by cross multiplying and then solving it from there:
5(m-3)=4(m-3)
5m-15=4m-12
5m-4m=-12+15
m=3
