Y >= -2x - 2

Intercept and slope check out for all these.

y > = is all y values ABOVE line because y is greater than the expression for line.

SOLID line when it's equal to. (dashed line when it's not).

HELP ME PLEASE True or false: z=−5 is a solution to the inequality −2|z−3|<−20.

Dovator [93]

your question: 

True or false: z=−5 is a solution to the inequality −2|z−3|<−20.

answer: 

-2|z-3|<-20

-------. -----

-2 -2

|z-3|<10

equation 1: equation 2:

z-3<10. z-3>-10

z<13 z>-13

So false, z=-5 is not a solution to the inequality.

hope this helps, have a great day! :)

Nifal earned 9$ for washing two cars .He recived $1 more for the second car.How much was he paid for washing each car?Which two

Sveta_85 [38]

Answer:

Nifal received $ 4 for washing the first car.

Nifal received $ 5 for washing the second car.

4 and 5 have a sum of 9.

Step-by-step explanation:

The problem can be rewritten as follows: Find the sum of two consecutive entire numbers equal to 9. That is:

$x + y = 9$

$y = x+1$

Then, by eliminating y:

$x + (x+1) = 9$

$2\cdot x + 1 = 9$

Now, let is clear $x$ :

$2\cdot x = 8$

$x = 4$

Nifal received $ 4 for washing the first car.

The earning for the second car is: ( $x = 4$ )

$y = x +1$

$y = 4 + 1$

$y = 5$

Nifal received $ 5 for washing the second car.

4 and 5 have a sum of 9.

Answer:

It's 24 packs of cat food

Step-by-step explanation:

You have to think of it as 30% of 80.

30 ?

----- = ----

100 80

Now you have to find out what is in the blank by doing 80 times 30 to find what that equals. That equals 2,400. Now you have to find what times a 100 gets you 2,400. You divide a 100 by 2,400 to get 24. There's your answer
