Answer:

y = 3x + 2

y = 6x – 3

y = 2/3x + 6

y = –1/3x – 4

y = 2x + 1

Correct answer:

y = 3x + 2

Explanation:

Convert the equation to slope intercept form to get y = –1/3x + 2. The old slope is –1/3 and the new slope is 3. Perpendicular slopes must be opposite reciprocals of each other: m1 * m2 = –1

With the new slope, use the slope intercept form and the point to calculate the intercept: y = mx + b or 5 = 3(1) + b, so b = 2

So y = 3x + 2

A function can be any straight line except a __________line.

mamaluj [8]

Answer: vertical line.

Step-by-step explanation:

Ok we can define a function f(x) as "something" that maps a given input (we usually call the input "x") into a given output (we usually call the output "y")

We have one rule for functions, each input can be mapped into only one output.

So if for example, for a given value x = A.

f(A) = B

and

f(A) = C

This is mapping the input A into two different outputs, then this is not a function.

Now to the question.

If we have a vertical line (parallel to the y-axis)

This line will have only one value of x associated with it, but all the values of y.

This means that this maps one value of the input into infinite outputs, then this can not be a function.

Marisa wants to buy a home in Atlanta with a 30-year mortgage that has an annual interest rate of 4.9%. The house she wants is $

Lady bird [3.3K]

Given :

Marisa wants to buy a home in Atlanta with a 30-year mortgage that has an annual interest rate of 4.9%.

The house she wants is $250,000 and she will make a $55,000 down payment and borrow the remainder.

To Find :

What is Marisa's monthly mortgage payment to the nearest dollar.

Solution :

Money remains, m = $( 250000 - 55000 ) = $195000 .

Total price after interest, T = m( 1 + rt )

T = 195000×( 1 + 0.049×1)

T = $204555

Monthly payment,

$M = \dfrac{m}{12}\\\\M = \dfrac{204555}{12}\\\\M =\$ 17046.25$

Therefore, monthly payment is $17046.25 .

Hence, this is the required solution.

Solve the inequality 13×-4 < 12x-1

Murrr4er [49]

Answer:

x <3

Step-by-step explanation:

13x-4 < 12x-1

Subtract 12x from each side

13x-12x-4 < 12x-12x-1

x-4 <-1

Add 4 to each side

x-4+4<-1+4

x <3
