Answer:
y = 3x -2
Step-by-step explanation:
If the line is parallel, that means it has the same slope. The given equation had a slope of 3, so the new line must also have a slope of 3.
You can plug the given coordinates into the slope-intercept form with a slope of 3 to find your answer.
y = m*x + b
7 = 3*3 + b
7 = 9 + b
-2 = b
y = 3x -2
Answer:
(4 , 12)
Step-by-step explanation:
let's call the number x the other number will be x/3
x + x/3 = 16
4x/3 = 16
4x = 48
x = 12

Step-by-step explanation:
1.5/4x-1=0.4/x+4
We move all terms to the left:
1.5/4x-1-(0.4/x+4)=0
Domain of the equation: 4x!=0
x!=0/4
x!=0
x∈R
Domain of the equation: x+4)!=0
x∈R
We get rid of parentheses
1.5/4x-0.4/x-4-1=0
We calculate fractions
(1.5x)/4x^2+(-0.4*4x)/4x^2-4-1=0
We add all the numbers together, and all the variables
(+1.5x)/4x^2+(-0.4*4x)/4x^2-4-1=0
We add all the numbers together, and all the variables
(+1.5x)/4x^2+(-0.4*4x)/4x^2-5=0
We multiply all the terms by the denominator
(+1.5x)+(-0.4*4x)-5*4x^2=0
Wy multiply elements
-20x^2+(+1.5x)+(-0.4*4x)=0
We get rid of parentheses
-20x^2+1.5x-0.4*4x=0
Answer : 
and 
Greatest common factor of 
If we are able to factor out from each option then that would be our answer.
Lets check with each options
(a)
, we cannot take out 5.
(b)
, We can take out common factor and it can be written as 
(c) 
, we cannot take out n^2 because we have only 'n'
(d) , We can take out common factor and it can be written as 
(e) 
, we cannot take out 5 because we have 24
So answer is (b) and (d)
