Answer: $x=2/5$ or $x=0.4$

Simplify the equation to the form

$6x-2=-4x+2$

Move all terms containing x to the left and all other terms to the right

$6x+4x=+2+2$

Simplify left and right side of the equation

$10x=+4$

Divide both sides of the equation by 10 to get x

$10x/10=4/10$

$x=2/5$ or $x=0.4$

6x-2=-4x+2
6x-2+2=-4x+2+2
6x=-4x+4
6x=-4x+4+4x
10x=4
10x/10 = 4/10
X=2/5

Ajay reads aloud from a sports magazine. He comes across the measurement 0.63 kilometer. How should he read this measurement alo

Mashutka [201]

Answer:

"sixty-three hundredths of a Kilometer"

Step-by-step explanation:

Decimal measurements are read based on the place of their digits. In this case, Ajay would read this measurement as "sixty-three hundredths of a Kilometer". This is because the final digit of the decimal form measurement is in the "hundredths" position. One more to the right and it would be in the "thousandths" while one more to the left would be the "tenths"

From 1997 - 2001 the number n (in millions) of black-and-white TV S sold in the U.S. Can be modeled by n = 26.8 * (0.85) ^ t whe

Alexandra [31]

Question

a) What is the decay factor?

b) What is the percent decrease?

c) Estimate the number of black and white TV's sold in 1999.

Answer:

a. Decay factor = 0.85

b. Percent decrease = 15%

c. 19.363 million TVs were sold

Step-by-step explanation:

Given

$n = 26.8(0.85)^t$

Solving (a): The decay factor

An exponential function has the form

$y = ab^x$

Where b is:

$b = decay\ factor\ or\ growth\ factor$

By comparison:

$b = 0.85$

Solving (b): Percentage decrease:

Percentage decrease P is calculated as follows:

$P = 1 - b$

Substitute 0.85 for b

$P = 1 - 0.85$

$P = 0.15$

Convert to percentage

$P = 0.15*100\%$

$P = 15\%$

Solving (c): TVs sold in 1999

First, we need to determine the value of t for 1999

In 1997, t= 0

In 1998, t= 1

In 1999, t= 2

So, we substitute 2 for t in: $n = 26.8(0.85)^t$

$n = 26.8(0.85)^2$

$n = 26.8*0.7225$

$n = 19.363$

Martin and Linda live 855 miles apart. At the same time, they start driving toward each other on the same road. Linda’s constant

Alinara [238K]

If one is at a speed of 35 mph and the other 60, sum the speeds to work with just one number:

35 + 60 = 95mph

The formula for time is:

Time = Distance / Speed
Time = 855 / 95
Time = 9h (D.)

Hope it helped,

Happy homework/ study/ exam!
