Answer:

x=4/3

Step-by-step explanation:

2+4=2(x-1)    original

6=2(x-1)        combine like terms

6=2x-2         multiply x-1 by 2

8=2x            add 2 to both sides

4=x              divide both sides by 2

A submarine is at the surface of the ocean. It begins its descent at a rate of 100 feet per minute. Write a linear model in the
Bingel [31]

Answer:

d(t) = -100t

Step-by-step explanation:

The general expression for the linear model is:

d(t)=mt+b

Since the submarine already starts at sea level, b=0:

d(t)=mt

The constant "m" is the rate at which the submarine descends in feet per minute. Considering depth as a negative quantity, m=-100

d(t)=-100t

The linear model that represents the depth of the submarine relative to sea level, in feet, after t minutes is d(t) = -100t.

Evaluate the expression: -4a2 + 3ab - (2a + 3b) if a = 1/4 and b = -12
svetlana [45]

Answer:

Value of equation = 26.25

Step-by-step explanation:

Given:

Equation given

-4a² + 3ab - (2a + 3b)

Given value of a = 1/4

Given value of b = -12

Find:

Value of equation

Computation:

-4a² + 3ab - (2a + 3b)

By putting value of a and b

-4(1/4)² + 3(1/4)(-12) - [2(1/4) + 3(-12)]

-4(1/16) - (36/4) - [2/4 - 36]

-4/16 - 36/4 - [-142/4]

- 0.25 - 9 + 142/4

-0.25 - 9 + 35.5

Value of equation = 26.25

Sam invested $48,000 some at 6% interest and the rest at 10% . How much did he invest at each rate if he received $4,000 in inte
emmainna [20.7K]

<u>Answer with step-by-step explanation:</u>

We are given that Sam invested $48,000 at 6% interest and the rest at 10%. Given that he received $4,000 interest in one year, we are to find how much he invest at each rate.

Assuming the amount invested at 6% interest rate as x, we can write it as:

(\frac{6}{100} \times x)+(\frac{10}{100} \times [48000-x])=4000

0.06x+0.1(48000-x)=4000

0.06x+4800-0.1x=4000

0.1x-0.06x=4800-4000

0.04x=800

x=20000

So the amount invested at 6% = $20,000 and amount invested at 10% = (48000 - 20000) = $28,000
