Answer 1

Answer:

The point-slope form:

$y-y_1=m(x-x_1)\n\nm=(y_2-y_1)/(x_2-x_1)$

We have two points (-2, -6) and (0, -2). Substitute:

$m=(-2-(-6))/(0-(-2))=(4)/(2)=2\n\ny-(-6)=2(x-(-2))\n\ny+6=2(x+2)\qquad|\text{use distributive property}\n\ny+6=2x+4\qquad|\text{subtract 6 from both sides}\n\ny=2x-2\qquad|\text{subtract 2x from both sides}\n\n-2x+y=-2\qquad|\text{change the signs}\n\n2x-y=2$

Answer:

point-slope form: y + 6 = 2(x + 2)

slope-intercept form: y = 2x - 2

standard form: 2x - y = 2

Show your work:Use the distributive property in two different ways to find the product of 127 and 32.

Answers

The distributive property: a(b + c) = ab + ac

127 × 32 = 127 × (30 + 2) = 127 × 30 + 127 × 2 = (130 - 3) × 30 + (130 - 3) × 2

=(130)(30) - (3)(30) + (130)(2) - (3)(2) = 3900 - 90 + 260 - 6

= 3810 + 254 = 4064

127 × 32 = (130 - 3) × 32 = 130 × 32 - 3 × 32 = 130 × (30 + 2) - 96

= (130)(30) + (130)(2) - 96 = 3900 + 260 - (100 - 4) = 4160 - 100 + 4

= 4060 + 4 = 4064

The sum of two numbers is 36. twice the first number minus the second is 6. find the two numbers

Answers

The values of the two numbers are 14 and 22 respectively.

Let the numbers be represented by x and y

Based on the information given, the equation to represent the information will be:

x + y = 36 ..... i

2x - y = 6....... ii

Add equation i and ii together

3x = 42

x = 42/3

x = 14

Since x + y = 36

Then, we'll put the value of x into the equation and this will be:

x + y = 36

14 + y = 36

y = 36 - 14

y = 22

Therefore, the values of x and y are 14 and 22 respectively.

What are the solutions to the equation 0=x2-x-6? Select two options X=-3
X=-2
X=0
X=2
X=3

Answers

Answer:

The correct options are,

x = -2 and x = 3

Step-by-step explanation:

It is given that,

x² - x - 6 = 0

To find the solution of given equation

x² - x - 6 = 0 can be written as

x² + 2x - 3x - 6 = 0

x(x + 2) - 3( x + 2) = =

(x + 2)(x - 3) = 0

Either (x + 2) = 0 or (x - 3) = 0

If (x + 2) = 0 then x = -2

If (x - 3) = 0 then x = 3

Therefore the correct options are,

x = -2 and x = 3

Sonja bought a new van for her business. The cost of the van was $35,000, and she had to pay 6% sales tax. What was the total cost of the new van, including tax? Can someone explain how to get the answer

Answers

All we do is this:
We take the amount of money and multiply it by the tax applied:
$35000 × 0.06 (6%= $(6)/(100)$ = 0.06)
=2,100 is the value we get
We add this value to the original price:
$35,000+2,100= $37,100
$37,100

Answer:

37,100

Step-by-step explanation:

multiply the price by the tax and then add that to the original price.
