Given:
The given equation is:

A line is perpendicular to the given line and passes through the point (4,-1).
To find:
The equation of required line.
Solution:
The slope intercept form of a line is:

Where, m is slope and b is y-intercept.
We have,

Here, the slope of the line is -4 and the y-intercept is 3.
Let the slope of required line be m.
We know that the product of slopes of two perpendicular lines is -1. So,



The slope of required line is
and it passes through the point (4,-1). So, the equation of the line is:




Therefore, the equation of the required line is
.

Answer:
x = 45/13, also x = 3 6/13
Step-by-step explanation:
is = equal sign
of = multiply
<u>Equation:</u>
To do this, you could easily do communitive property of multiplication, but to make it more understandable I will use reversing.
1. Simplify. Multiply - Divide.

2. Factor out common term 5.

3. Multiply both sides by 3.

4. Expand.

5. Add <em>10x</em> to both sides.

Simplify. <em>3x + 10x = 13x.</em>

Divide both sides by 13.

Mixed Number =
.
You can also use distributive property. The formula for this problem is:

Answer: $3.60
Step-by-step explanation:
If you need 4.8 kilograms of potatoes and each kilograms costs $0.75, then we should multiply 0.75 by 4.8 to find the cost of 4.8 kilograms of potatoes.
4.8 x 0.75 = 3.6.
Therefore, the cost of 4.8 kilograms is $3.60 dollars. I hope this helps, and good luck!
