1.4x + 1.2x - 3.8 = -9

1 answer:

4 0

First, to make the equation easier to read, you want to add the x’s together. you should then get 2.6x-3.8=-9. then, you want to add the 3.8 to both sides, to make the x stand alone. you should end up with 2.6x=-5.2. to find x, you then want to divide both sides by 2.6. your final answer after dividing should be x=-2

Morgan works at a store that sells clothing accessories. The supply function

jarptica [38.1K]

Answer:

The number of supply of base balls is 22

Step-by-step explanation:

Given

P = Q - 4

Price = $18

Required

Number of supply

The relationship between price and quantity is given to be P = Q - 4 where price is represented by P and Q represents the quantity.

To get the quantity supply when price is $18, all you need to do is to substitute 18 for P in the above equation;

Thus, giving:

18 = Q - 4

Make Q the subject of formula

Q = 18 + 4

Q = 22 quantities

Hence, the number of supply of base balls is 22

Answer:

563 - (563x0.25) = 422.25 -> 422

422 -(422x0.25) = 316.5 -> 317

317 - (317x0.25) = 237.75 -> 238

238 - (238x0.25) = 178.5 -> 179

28 (continue the step by step process)

134.25 -> 134

100.5 -> 101

75.75 -> 76

42.75 -> 43

32.25 -> 32

Step-by-step explanation:

the time interval has to keep skipping by four hours because the medicine is filtered in that amount of time.

The multiplying by 0.25 part must be done first in order to show how much the kidney has filtered.

after this, you need to subtract that from how many milligrams of medicine are left in your system

note that if you do not subtract, you will only be showing how much the kidney has filtered. the question asks for how much is left in the SYSTEM overall, so subtracting is quite necessary to completely answer the question.

I hope this helped.

Samuel compared the monthly rental rates of two-bedroom apartments in Beverly and Lowell over the years. The results are shown i

Semenov [28]

Answer:

B. Only the monthly rental cost of apartments in Lowell is changing exponentially.

Step-by-step explanation:

To identify how the values of the monthly costs of the departments are changing, we must do a test.

The test consists of taking an element $n_{-1}$ and the element n of the series, and dividing $\frac{n}{n_{-1}} = a$

Then take the element $n_{+1}$ and the element n and divide $\frac{n_{+1}}{n} = b$

If b = a, then the exponential function of base "b"

But if b> a, then the rate of change of the function is not exponential

For example. For the cost of apartments in Beverly

$n_{-1} = 1870\\n = 1890\\n_{+1} = 1950\\\\\frac{n}{n_{-1}} = \frac{1890}{1870} = 1.011\\\\\frac{n_{+1}}{n} = \frac{1950}{1890} = 1.032\\\\1,032> 1,011$
