Answer:

x=-2

Step-by-step explanation:

step 1 -5x-1-5=4

step 2 -5x-6=4

step 3 -5x=10 cause you add 6 on both sides

step 4 and then divide both sides by -5 to get x=-2

Answer:

x= -2

Step-by-step explanation:

-0.2(25x+5)-5 = 4

We move all terms to the left:

-0.2(25x+5)-5-(4) = 0

We add all the numbers together, and all the variables

-0.2(25x+5)-9 = 0

We multiply parentheses

-5x-1-9 = 0

We add all the numbers together, and all the variables

-5x-10 = 0

We move all terms containing x to the left, all other terms to the right

-5x= 10

x=  10/-5

x= -2

Describe the relationship of input and output values for composite functions?
lora16 [44]
Hello there!

I want you to think of functions as machines! Let's start with one function, and we will call it f. if we were to plug in x to the machine, x would be an input. Let's say we get 1 everyone we plug in x to the f machine. This would mean the 1 is the output! f(x)=1

Now let's talk about composite functions! Let's say we have TWO machines, f and g. If we plug in x to the f machine, then we would get 1. If we plugged that 1 that we got as an output from the f machine into the g machine, then we would have g(1)=5. THIS is how a composite function works. g(1) is actually g(f(x)) because f(x)=1.

I REALLY hope this analogy helps you out! I apologize if it doesn't, however I've noticed that many people have had success in thinking about functions in this way!

If you need more elaboration, feel free to message me!


Best wishes :)

The garden outside Ms.Mertz's class needs 5 liters of water a week. Jacob poured 326 millimeters of water on the garden on Monda
AleksandrR [38]

Answer:

Enough water has been poured .

Step-by-step explanation:

The garden needed water in a week = 5 liters

Jacob poured water on Monday = 326 ml = ( 326/ 1000) liters = 0.326 liters.

SEAN poured water on Tuesday = 1.5 liters

Gavin poured water on Wednesday = 2312 ml = ( 2312/ 1000) = 2.312 liters.

Stephen poured water on Thursday = 894 ml = ( 894/ 1000)  = 0.894 liters

The total amount of water poured by all these people = 0.326 + 1.5 +2.312 +0. 894 = 5.032 liters

Here we can see that water has been poured is more than the water required  in a week.

You have a mean score of 84 after taking five 100-point tests. What do you need to score on the sixth 100-point test to have a m
kap26 [50]
The mean of n numbers is the sum of the numbers divided by n.

You have a mean score of 84 after taking 5 tests. Let x be the sum of scores.
\frac{x}{5}=84 \\
x=84 \times 5 \\
x=420
You scored a total of 420 points on five tests.

You need to have a mean score of 85 after taking 6 tests. Let y be the score you need to obtain. Your total score on 6 tests is 420+y.
\frac{420+y}{6}=85 \\
420+y=85 \times 6 \\
420+y=510 \\
y=510-420 \\
y=90

You need to score 90 points on the sixth test.
