Answer:

b = √12

Step-by-step explanation:

Pythogerom Thyrom

a^2 + b^2 = c^2

2^2 + b^2 = 4^2

4 + b^2 = 16

Find the value of b

4 - 4 + b^2 = 16 - 4

b^2 = 12

b = √12

The answer is c.

Since a^2+b^2=c^2, b^2=c^2-a^2 thus,
16=4-b^2= srt. of 12

Which of the following is an equation for a line that is NOT parallel to the other three?
galben [10]

The equation of the line that is not parallel to others is (C) 2x-3y= -1

<h3>How to determine the equation of the line is not parallel?</h3>

From the question, we have the following parameters that can be used in our computation:

A) 3x-2y=5

B) -3x+2y=9

C) 2x-3y= -1

D) -3x+2y=8

Make y the subject in equations

So, we have the following representation

A) y = 3/2x - 5/2

B) y = 3/2x + 9/2

C) y= 2/3x + 1/3

D) y = 3/2x + 4

As a general rule of linear equations

Parallel lines have equal slope

A linear equation is represented as

y = mx + c

Where

slope = m

Using the above as a guide, we have the following:

A) y = 3/2x - 5/2 ⇒ slope = 3/2

B) y = 3/2x + 9/2 ⇒ slope = 3/2

C) y= 2/3x + 1/3 ⇒ slope = 2/3

D) y = 3/2x + 4 ⇒ slope = 3/2

Hence, the line that is not parallel is (c)

Find the equation of the line in standard form containing a point P(-3, 3) and a slope m = -4/3
Ghella [55]

Answer:

4x+3y+3=0

Step-by-step explanation:

Equation of a line containing a point (x1,y1),

and a slope m is given by,

(y-y1)=m(x-x1)

Here, x1= -3 , y1= 3 , m= -4/3

Putting the values,

(y-3)=-4/3(x+3)

or,3(y-3)=-4(x+3)

or,3y-9=-4x-12

or,4x+3y+3=0 , is the required equation.
