|a| = b gives
a =b or a = -b

so,
|-x| = -10
gives
-x = -10 or -x = 10
x = 10, -10

now let us verify,
when x = 10, |-10| = +10 and it is not = -10
so, x= 10 is NOT a solution.

when x = -10, |-(-10)| = |10| = 10 and it is not = -10
so, x= -10 is NOT a solution.

hence, this equation does not have a solution.

If we know that |...| can never be negative, we can directly deduce that this equation does not have any solution.

Find the variables! please help

Answer:

x = 3, y = 5

Step-by-step explanation:

As per the diagram we got:

FH = GH = EH

As FH = 7x + 4 and EH = 9x - 2, we solve the following equation for x:

7x + 4 = 9x - 2
9x - 7x = 4 + 2
2x = 6
x = 3

So each segment is:

7*3 + 4 = 25

Therefore:

5y = 25
y = 5

So the variables are:

x = 3, y = 5

What could explain what happened when the time was equal to 120 minutes

tensa zangetsu [6.8K]

Answer:

Step-by-step explanation:

Alright, lets get started.

Lets split the given graph in three parts.

First part: 0 to 30 minutes

We can see between this period, 0 to 30 minutes, the distance from home keeps increasing. It means from 0 to 30 minutes, Eli is moving towards the library.

Second part: 30 to 120 minutes

between 30 to 120 minutes,the distance from home does not changes. It means during this period, Eli is at the library.

Third part : 120 minutes to 135 minutes

Between 120 to 135 minutes, the distance from home is decreasing.

It means Eli is returning home in that period.

It means, at 120minute, Eli started her bicycle , home from the library. Hence option (b) : Answer

Hope it will help :)

Biochemistry lab is worth 25% of your total MCB 2000 course grade. Of that 25%, the weekly laboratory reports account for 45%. F

Oksi-84 [34.3K]

Answer: 1%

Step-by-step explanation: Total 2,000

BioChem Lab: 25% of total = 25% . 2000 = 500

LabRep: 45% of Lab = 45% . 500 = 225

There will be 9 LabRep: 225/9 = 25

Participation: 10% of LabRep = 10% . 25 = 2.5

Actual LabRep: 90% of LabRep = 90% . 25 = 22.5

So, each lab report is worth 22.5 of 2000 = 2.5/2000 = 0.01125 = 1.125%

Nearest whole number = 1%
