Which equation is parallel to the line LaTeX: y=\frac{1}{2}x+3y = 1 2 x + 3and passes through the point (10, -5)?
sukhopar [10]

Answer:

Equation\ of\ line:\ y=\frac{1}{2}x-10

Step-by-step explanation:

Let\ the\ required\ equation\ is\ y=mx+c\\\\where\ m\ is\ the\ slope\ of\ the\ equation\ and\ c\ is\ y-intercept\\\\It\ is\ parallel\ to\ the\ equation\ y=\frac{1}{2}x+3\\\\Hence\ slope\ of\ these\ two\ lines\ will\ be\ same.\\\\Slope\ of\ y=\frac{1}{2}x+3\ is\ \frac{1}{2}\\\\Hence\ slope\ of\ y=mx+c\ is\ \frac{1}{2}\Rightarrow m=\frac{1}{2}\\\\Equation:y=\frac{1}{2}x+c\\\\Line\ passes\ through\ (10,-5).\ Hence\ this\ point\ satisfies\ the\ equation\ of\ line.\\\\-5=\frac{1}{2}\times 10+c

-5=-5+c\\\\c=-10

Equation\ of\ line:\ y=\frac{1}{2}x-10

Solve using the order of operations: 6.3 7 squared x 3.1
SVETLANKA909090 [29]
6.37² x 3.1

First is Exponents (6.37²):

40.6 x 3.1

Then, Multiplication:

40.6 x 3.1 = 125.9.

To remember the order of operations, the term PEMDAS can be used. (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.)
You do the equation in the order of the letters.

Example:

(5-2)5 + 2² / 6 -1 = ?

First, Parentheses:

(3)5 + 2² / 6 - 1

Then, Exponents:

(3)5 + 4 / 6 - 1

Then, Multiplication:

15 + 4 / 6 - 1

Then, Division:

15 + 0.7 - 1

Then, Addition:

15.7 - 1 

Then, Subtraction:

14.7

So that means, (5-2)5 + 2² / 6 -1 = 14.7

Potential roots have the format

factors of the constant term
-------------------------------------
factors of the initial term

Here, 7/3 is the only possible root that has a 7 in the numerator and a factor of 9 in the denominator.

Verify that 7/3 is a root using synthetic division.
