Can you tell me what is 15-2x=3x

Answers

Answer 1

Answer: 15 - 2x = 3x
15 = 3x + 2x
15 = 5x
5x = 15
x = 15/5 = 3

Answer 2

Answer: The answer is 3x because first you will add 2x on both sides which will give you 5x on the other side. Then you divide 5x on both sides. 15/5x=3x

What is the vertical asymptote for the function f(x) = ln(x + 4) - 2? Be sure to write your answer as an equation for a line.

Answers

f(x) = ln (x+4) -2
Change f(x) to y
y=ln (x+4) -2
Inverse x and y
x=ln(y+4) -2
Solve for y, result will be inverse.
x+2=ln(y+4)
convert to exponential form
e^(x+2) = y+4
y=e^(x+2) -4
This is the inverse.
f^-1(x) = e^(x+2) -4

Looking at the above function, it is (e^x) shifted to the left by two unit, being brought down (4) units. The only important part of this function is the down-shift of (4), because this represents the horizontal asymptote.

y = -4 is the horizontal asymptote, which means

for f(x) =ln(x+4) -2
x=-4 is a vertical asymptotes.

What is the volume of a rectangular prism with a length of 812 cm, width of 913 cm and a height of 1225 cm?

Answers

812*913*1225 = 908161100cm^3
or 8.12*9.13*12.25 = 908.1611 m^3

Volume is Length X width X height. They already give you the values, so you'd multiply 812 by 913 and 1225, which would give you;

908161100

On a recent trip to the convenience store, you picked up 4 gallons of milk, 6 bottles of water and 5 snack size bags of chips. You total bill before tax was $ 27.2. If a bottle of water costs twice as much as a bag of chips, and a gallon of milk costs $1.80 more than a bottle of water, how much does each item costHow much does a snack size bag of chips cost?

How much does a bottle of water cost?

How much does a gallon of milk cost?

Answers

Answer:

Cost of a snack size bag of chips = $0.8

Cost of a water bottle = $1.6

Cost of a gallon of milk = $3.4

Step-by-step explanation:

Let the cost of water bottle = $a

Cost of 1 gallon milk = $b

and cost of 1 bag of chips = $c

So, cost of 4 gallons of milk, 6 bottles of water and 5 bags of chips = $(4b + 6a + 5c)

4b + 6a + 5c = 27.2 -----(1)

Cost of one water bottle = 2 × cost of one bag of chips

a = 2c -----(2)

A gallon of milk = cost of water bottle + $1.80

b = a + 1.8

From equation (2)

b = 2c + 1.8 -----(3)

Now we substitute these values from equations (2) and (3) in equation (1)

4(2c + 1.8) + 6(2c) + 5c = 27.2

8c + 7.2 + 12c + 5c = 27.2

25c = 27.2 - 7.2

c = $(20)/(25)$

c = $0.8

From equation (2)

a = 2×0.8

a = $1.6

From equation (3)

b = 2(0.8) + 1.8

b = 1.6 + 1.8

b = $3.4

Therefore, cost of a snack size bag of chips = $0.8

Cost of a water bottle = $1.6

Cost of a gallon of milk = $3.4
