Write the equation of a line that is
il63 [147K]

Answer:

Y= 3x-7

Step-by-step explanation:

Since the line is parallel , the slope is same i.e. 3 .

now the equation should be y= Mx + b where m is the slope and c is the y-intercept

plugging the value of m=3 and ( 3,2) into the equation

2= 3(3) + c

2= 9+ c

c= -7

hence the equation of the line is y=3x-7

The table below shows a pattern in the cost of renting a car based on the number of days rented. Car Rentals Number of Days (d)
andrezito [222]

The linear equation that describes the pattern in the cost of renting a car is given by:

  • D. c = 34d + 25

<h3>What is a linear function? </h3>

A linear function is modeled by:

y(x) = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0.

In this problem:

  • For each day, the cost of renting a car increases by 34, hence, the slope is of 34, and the equation is:

c(d) = 34d + b

When d = 4, c = 161, and this is used to find b.

c(d) = 34d + b

161 = 34(4) + b

b = 25

Hence, the equation is c = 34d + 25, and option D is correct.

Given the trinomial, what is the value of the coefficient B in the factored form? 2x2 + 4xy − 48y2 = 2(x + By)(x − 4y) −12 12 −6
Sonja [21]

Answer:

B is 6.

Step-by-step explanation:

We are trying to find a value for B such that:

2x^2+4xy-48y^2=2(x+By)(x-4y) is true for every x,y.

So let's choose x=0,y=1:

2(0)^2+4(0)(1)-48(1)^2=2(0+B(1))(0-4(1))

2(0)+0-48=2(B)(-4)

0-48=-8B

-48=-8B

Divide both sides by -8:

\frac{-48}{-8}=B

6=B

B=6

Note: I didn't want to choose y to be 0 because the value of B would disappear from the equation. So you should be able to have chosen any x and y except for y=0 to solve the equation for B.

Check:

So let's check and use foil to multiply out the right hand side.

(x+6y)(x-4y)

x(x)+x(-4y)+6y(x)+6y(-4y)

x^2-4xy+6xy-24y^2

x^2+2xy-24y^2

There was a 2 in front of that multplicapltiation:

2(x+6y)(x-4y)

2(x^2+2xy-24y^2)

2x^2+4xy-48y^2

This is exactly what we have on the left hand side of your given equation.
