Answer:

-2 <u>12</u>

-1 <u>7</u>

0 <u>2</u>

1 <u>-3</u>

2 <u>-8</u>

Step-by-step explanation:

[] With the function f(x)=2−5x we can tell that we will plug x into the equation without doing anything to it (x)

-2 ___

f(-2) = 2−5x

f(-2) = 2−5(-2)

f(-2) = 2 + 10

f(-2) = 12

-1 ___

f(-1) = 2−5x

f(-1) = 2−5(-1)

f(-1) = 2 + 5

f(-1) = 7

0 ___

f(0) = 2−5x

f(0) = 2−5(0)

f(0) = 2

1 ___

f(1) = 2−5x

f(1) = 2−5(1)

f(1) = 2 - 5

f(1) = -3

2 ___

f(2) = 2−5x

f(2) = 2−5(2)

f(2) = 2−5(2)

f(2) = 2−10

f(2) = -8

Have a nice day!

What would be the answer to both?
dezoksy [38]

Answer:

f(- 3) = 51, g(2) = - 11

Step-by-step explanation:

To evaluate f(- 3), substitute x = - 3 into f(x), that is

f(- 3) = - 2(- 3)³ - 3 = - 2(- 27) - 3 =  54 - 3 = 51

Similarly for g(2)

g(2) = - 5(2) - 1 = - 10 - 1 = - 11

Please Help 6th Grade Math! Box Plots! 2 questions (Image attached)​
tangare [24]

Answer:

First answer is 14

Second answer is 25

Step-by-step explanation:

Median is the middle ( 1 2 3 4 5 the median would be 3)

You start at 2 and end at 27

List all the numbers from 2 to 27 and come from both ends until you get to the middle number(s)

In this case there are two 14 & 15

14+15=29 29÷2=14.5

Since there are no decimal answers you are left with 14

Range you take the two end numbers and subtract them (27 & 2)

27-2=25

Hopefully this helps!

Can plz help me in this question asap I don't get it
34kurt

Answer:

-19+-25f≤-144

Step-by-step explanation:

The problem says that you descended 19 below sea level. Below makes 19 into a negative. It also says that it descends 25 feet per minute. If it says per you put a variable by that number. It also says descends which means going down so that would be a negative. The problem says Lainey does not want to go over 144 feet(144 is also negative because it is below sea level) so 144 would be greater than or equal to because she does not wan to go over that amount.

Hope this helps!
