I believe its A, since the absolute value brackets are used to show how far away a number is from 0. All of the other answers are correct, but A makes the most sense here.

Find the equation of a line that is perpendicular to 4x+6y=1 that has a greater y intercept compared to 2x+3y=18
Marina86 [1]

Answer:

4y = 6x + 40

Step-by-step explanation:

The general equation of a straight line is y = mx + b

m is the slope and b is the y-intercept

let us write both equations in this form;

we have this as;

6y = -4x + 1

y = -4x/6 + 1/6

and;

2x + 3y = 18

3y = -2x + 18

y = -2x/3 + 6

So firstly we want to find an equation that is perpendicular to the first

When two lines are perpendicular, their slopes has a product of -1

The slope of the first line is -4/6

let the slope of the line we want be m

As per they are perpendicular;

-4/6 * m = -1

-4m/6 = -1

-4m = -6

m = 6/4

So now, we want the y-intercept greater than that of the second equation which is a y-intercept of 6

we can choose 10

and we have the equation as:

y = 6x/4 + 10

multiply through by 4

4y = 6x + 40

(×-5) second power equals 3​
Snezhnost [94]

Answer: x_1=6.73\\\\x_2=3.26

Step-by-step explanation:  

Given the following expression:

(x-5)^2=3

And knowing that:

(a\±b)^2=a^2-2ab+b^2

We get:

x^2-2(x)(5)+5^2=3\\\\x^2-10x+25=3

Move the 3 to the left side of the equation:

x^2-10x+25-3=0\\\\x^2-10x+22=0

Apply the Quadratic formula:

x=\frac{-b\±\sqrt{b^2-4ac} }{2a}

In this case:

a=1\\b=-10\\c=22

Substituting values into the Quadratic formula, we get:

x=\frac{-(-10)\±\sqrt{(-10)^2-4(1)(22)} }{2(1)}\\\\\\x_1=6.73\\\\x_2=3.26
