Answer:

If the slope is positive it is increasing if the slope is negative it is decreasing :)

Example:

Y=mX+b

If m is positive it is a positive slope

The slope of the line will tell you whether it is decreasing or increasing.
negative slopes means it’s decreasing while positive slopes means the line is increasing.

Alana earnerd money doing chores. Her grandmother agreed to add $4.00 to the amount Alana earned and then give her half of that
vitfil [10]

Answer:

Hence amount of Alana's donation is $4.5.

Step-by-step explanation:

Amount of Alana's donation = x

Her grandmother agreed to add $4.00 to the amount Alana earned.

So new amount of money = (x+4)

She gives only half of the sum which is (x+4)/2.

She gave her $4.25 so both values must be equal.

\frac{\left(x+4\right)}{2}=4.25

x+4=4.25*2

x+4=8.5

x=8.5-4

x=4.5

Hence amount of Alana's donation is $4.5.

2x + 3 + 4x + 6 + 12x + 18 = 477<br><br> Please answer with solving steps. Thanks guys :)
dybincka [34]

Answer:

x= 25

Step-by-step explanation:

2x + 3 + 4x + 6 + 12x + 18 = 477

FIRST combine like terms

take all "x"

2+4+12= 18x

take all whole numbers

3+6+18= 27

18x+27= 477

now solve for x

-27 on both sides

18x= 450

÷18 on both sides

x= 25
