Answer:

-2

Step-by-step explanation:

As we move right from (-6,12) to (-2,4), x increases by 4 and y decreases by 8.  Thus, the slope of the line thru these 2 pts is m = rise / run = -8/4 = -2.

The first answer choice is the correct one:  The slope is -2.

Use the discriminant to determine the nature of the roots of the following equation.
kvv77 [185]

Discussion

The discriminate is b^2 - 4*a*c

The general equation for a quadratic is ax^2 + bx + c

In this equation's case

a = 1

b= -5

c = - 3

Solve

(-5)^2 - 4*(1)*(-3)

25 - (-12)

25 + 12

37

Note

Since the discriminate is > 0, the roots are real and different. The roots do exist and there are 2 of them.

Determine whether each equation represents a proportional relationship
wlad13 [49]

Hey there! I'm happy to help!

A proportional equation follows the form y=kx, where k is the constant of proportionality.

Answer 1 is wrong because there is something added.

2 is correct as it follows this format.

3 is incorrect as it does not follow this format.

4 is correct as it follows the format (k is 1)

5 Is correct because it follows this format.

6 is not correct because there is a 1 added, which does not follow the format.

Therefore, the correct answers are 2, 4, and 5.

Have a wonderful day! :D

At the fast food restaurant, an order of fries costs $1.05 and a drink costs $1.07. How much would it cost to get 3 orders of fr
trasher [3.6K]

Answer:

$7.43

Step-by-step explanation:

f (fries) = 1.01

d (drinks) = 1.07

1.05f + 1.07d = ?

To solve this problem, you need to replace the variable with the amount of each item.

1.05(3) + 1.07(4) = ?

Now we can solve by multiplying and adding:

3.15 + 4.28 = ?

<u>7.43</u>
