Answer:

1).  Correct answer is D

2). Correct answer is A

Step-by-step explanation:

1).

For the points given, (-1, -1) and (2, -2), we have to find the slope.

Slope formula is (y2 - y1) / (x2 - x1), or rise over run.

Simply fill in the formula and you will get:

y2 = -2

x2 = 2

y1 = -1

x1 = -1

OR

(-2 - (-1)) / (2 - (-1)) which is D

2).

For the two points given, (2, 0) and (0, -3), find the slope.

Using the same equation above, (y2 - y1) / (x2 - x1), or rise over run, fill it in and solve and you will get your answer.

y2 = 0

x2 = 2

y1 = -3

x1 = 0

(0 - (-3)) / (2 - 0) = 3/2 which is A

Step-by-step explanation:

Graph A:

D ((y2-y1)/(x2-x1) or (y1-y2)(x1-x2))

Graph B:

A (same as above or simply take the rise divided by the run)

a shipping company charges x dollars to ship a package that weighs up to 1 pound and an additional fee based on the additional w
stepan [7]

Let the additional fee , the shipping company charges be $y .

So for 0.75 pounds, since the weight is less then 1 pound, company charge = $2x

For 3 packages with weigh 2.5 pounds, company charge 3* ( x+(2.5-1)*y )

= 3x+4.5y

For package with weighs 4.2 pounds, company charge x+(4.2-1)y = x+3.1y

So the total amount , company charge = 2x +3x +4.5y +x+3.1y

=6x +7.6y

In the 2017 fiscal year, the state of Alaska received $8.2 billion In revenues and had $7.2 billion in expenditures. What percen
konstantin123 [22]
To figure this out you can do 7.2/8.2, because you are trying to figure out how much of the total was used, and percentages would not be more than 100%. Doing this you would get ~.878. To convert this to a percent, you would just multiply it by 100, which would give you 87.8%. The question states to round to the nearest whole percent, leaving you with 88%. This means that 88% of the revenue was spent.

Hope that helped, don't be shy to comment on this if you have any questions about my explanation :)

Can Some one please help me on these math questions<br><br>I'll give 20 points please
MArishka [77]

Answer:

☐ -2 < 2x + 4

☐ -3x - 2 > 5

Step-by-step explanation:

-3x - 2 > 5

+ 2 + 2

___________

-3x > 7

___ ___

-3 -3

x < -2⅓ [Anytime you <em>divide</em> or <em>multiply</em> by a negative, reverse the inequality symbol.]

-2 < 2x + 4

-4 - 4

___________

-6 < 2x

__ ___

2 2

-3 < x

If you plug in -3 for <em>x < -2</em><em>⅓</em><em>,</em><em> </em>you will see that it is a genuine statement because the more higher a negative gets, the lesser the integer will be, so in this case, -3 IS <em>less</em><em> </em><em>than</em><em> </em>-2⅓.

I am joyous to assist you anytime.

** If it is not multi-select, then choose <em>-2 < 2x + </em><em>4</em><em>.</em>
