Identify the graph of the inequality 2(2x - 1) + 7 < 13 or -2x + 55-10.
lutik1710 [3]

Answer:

The answer is the last one.

Step-by-step explanation:

Firstly, look at the first inequality and we get 4x+5, so x. In the second inequality, we have 15\leq 2x, so x\ge 7.5. Together, we know that the answer is the last one.

Present value sura wiggle would like to make a single investment have 2.2 million at the time of her retirement in 28 years she
levacccp [35]

Answer:

if the annual interest rate is 7%, then you need to invest:

present value = future value / (1 + i)ⁿ

  • future value = $2,200,000
  • i = 7%
  • n = 28 years

present value = $2,200,000 / (1 + 7%)²⁸ = $330,884.87

if the interest rate is 15%, the you need to deposit a smaller amount:

present value = future value / (1 + i)ⁿ

  • future value = $2,200,000
  • i = 15%
  • n = 28 years

present value = $2,200,000 / (1 + 15%)²⁸ = $43,942.34

Tom works at an aquarium shop on Saturdays. One Saturday, when Tom gets to work, he is asked to clean a 180-gallon reef tank. Hi
vlada-n [284]

Please find the question attached below.

The equation that models the decrease in water (in gallons) of the fish tank over time (in hours) is y = - 20x + 180.

We know that a linear equation with one variable is one that contains just one variable.

Here we have to find the appropriate equation that models the given chart.

For option A. :

y = - 40x + 140

At x = 2, y = - 40*2 + 140 = - 80 + 140 = 60 =/ 140

So this option is incorrect.

For option B.:

y = - 40x + 180

At x = 2, y = - 40*2 + 180 = - 80 + 180 = 100 =/ 140

So this option is incorrect.

For option C.:

y = - 20x + 140

At x = 2, y = - 20*2 + 140 = - 40 + 140 = 100 =/ 140

So this option is incorrect.

For option D.:

y = - 20x + 180

At x = 2, y = - 20*2 + 180 = - 40 + 180 = 140

So this option is correct.

Therefore, the equation that models the decrease in water (in gallons) of the fish tank over time (in hours) is y = - 20x + 180. So, the last option is correct.
