2/5m - 4 + = 16 + is what?

Mathematics
1 answer:
asambeis [7]3 years ago
8 0

Answer:

2/5m-4=16

We move all terms to the left:

2/5m-4-(16)=0

Domain of the equation: 5m!=0

m!=0/5

m!=0

m∈R

We add all the numbers together, and all the variables

2/5m-20=0

We multiply all the terms by the denominator

-20*5m+2=0

Wy multiply elements

-100m+2=0

We move all terms containing m to the left, all other terms to the right

-100m=-2

m=-2/-100

m=1/50

What is the equation of the line that passes through (-3, -1) and has a slope of 2/5? Put your answer in slope-intercept form.
Zanzabum
Hi there!

The general formula of A line in slope-intercept form is the following:
y = mx + n

In this formula m represents the slope of the line. Therefore, we can conclude that m = 2/5.
y =  \frac{2}{5} x + n

We also know that the line passes through the point (-3, -1) and we can therefore substitute this coordinate into the formula of the line.
x = -3 and y = -1

- 1 =  \frac{2}{5}  \times  - 3 + n

Multiply first.
- 1 =  -  1\frac{1}{5}  + n

And finally add 1 1/5 to both sides of the equation.
\frac{1}{5}  = n

We can now switch sides.
n =  \frac{1}{5}

Now we've found our value of n, which we can substitute into the formula of our line. Hence, in slope-intercept form, we find the following:
y =  \frac{2}{5}  x  +  \frac{1}{5}
