ANSWER THESE 3 QUESTIONS OF THESE FOR 30 POINTS, THANK YOU!!1. Solve X2 = 169A. UndefinedB. 13C. 13D.
Answer 2
Problem number 1 is a, because 13^2 is 169, and you can’t have a negative number as a result of squaring (pos times pos = pos, neg times neg = pos

Problem number 2 is B. It is irrational, but closer to 1.7 than 1.8

Problem number 3 is D, 4 over 3. 4 cubed =64, 3 cubed = 27

360-283=77

180+77=257

The exterior angles of any polygon (a shape with 3 or more sides) is always equal to 360 degrees.

If you add up all the provided angles you get 283 degrees

The remaining angle to get to 360 is 77 since 360-283=77

What is the equation of the line that is perpendicular to the
given line and has an x-intercept of 6?
y=-3x+8
O y=-3x + 6
O y=-x-8
O y=x-6

Answers

Answer:

y=x-6

Step-by-step explanation:

The x-intercept is found replacing y = 0, as follows:

Function: y = -3x + 8

x-intercept:

0 = -3x + 8  

3x = 8

x = 8/3

Function: y = -3x + 6

x-intercept:

0 = -3x + 6

3x = 6

x = 6/3 = 2

Function: y = -x - 8  

x-intercept:

0 = -x - 8  

x = -8

Function: y = x - 6

x-intercept:

0 = x - 6

x = 6

The last option is the only one in which x-intercept is x = 6.

-16 + 3n = -8 - 5n what does n equal?

Answers

Step-by-step explanation:

-16 + 3n = - 8 - 5n

Bringing like terms on one side

3n + 5n = - 8 + 16

8n = 8

n = 8/8

N = 1

Answer:

n=1

Step-by-step explanation:

-16+3n=-8-5n

-16+8=-5n-3n

-8=-8n

-8n=-8

n=1

Proof:

-16+3n=-8-5n

-16+3(1)=-8-5(1)

-16+3=-8-5

please write a function for the points (1/3,0) (-2 3/4,0) and (0,-5) and explain the steps.
thank you!

Answers

The function for the points are  y = -15x - 5

How to determine the function

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

m is the slope of the liney - y₁ and (x - x₁) are the points

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

#SPJ1

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)
