What are the missing angles

Help! What si the verbal expression for this algebraic expression: 2x - 4 < 4x +8

katrin2010 [14]

Answer:

C. Four less than the product of two and a number is less than the product of four and the same number increased by eight.

General Formulas and Concepts:

Pre-Algebra

Converting expressions to word form

Step-by-step explanation:

Step 1: Define

2x - 4 < 4x + 8

Step 2: Translate

"2x" is the product of two and a number x

" - 4" is four less

"<" is less than

"4x" is the product of four and a number x

" + 8" is increased by 8

Step 3: Combine

The difference between the product of two and a number x and 4 is less than the sum of the product of four and a number x and 8.

Step 4: Reword

Four less than the product of two and a number is less than the product of four and the same number increased by eight.

Explain how to convert numbers from standard form to scientific.

sweet [91]

Answer:

Start by moving the decimal place in the number until you have a coefficient between 1 and 10. The number of places to the left that you had to move the decimal point is the exponent. so for example, 0.000345 would be 3.45(10)^4

Step-by-step explanation:

Hope that helps!

Select the rational expression that is equivalent to the given expression below. 4 over x - 3

Ad libitum [116K]

When you say 1 over 3, you are basically saying 1 divided by 3, or expressed as a rational number: $\frac{1}{3}$ . in our rational number the denominator is 1, and the numerator is 3

Now, a rational expression is an algebraic expression in a rational for. If we apply the same to your problem. 4 over x-3 means 4 divided by x-3, or in mathematical notation: $\frac{4}{x-3}$ . In this case, the numerator is 4, and the denominator is $x-3$ .

We can conclude that the equivalent rational expression of 4 over x - 3 is $\frac{4}{x-3}$ .

this value of y is a of t(y). because is for all values of y, it follows that the value of y found in the previous step corres

Radda [10]

For f(t) = 3 sin(t), the minimum is -3, the maximum is 3.

For additional information:

The period T of the function y=3sin(4t) is;

The period of y = 3 sin (4t) is (2pi) / 4 = pi / 2

The sine function with amplitude A = 0.75 and period T = 10, is

y = 0.75 sin( (2pi / 10) x )

= 0.75 sin( (pi/5) t)

y(4) = 0.75 sin( (pi/5) (4) )

= 0.75 sin ( (4/5) pi ) = .4408

Drawing the sine and cosine function on the same plot shows

that they are identical except for a horizontal shift.

The cosine

function leads the sine function by a shift of (2pi/4) = pi/2.

For the last part, y(4) = 0.75 cos( (2pi/10) (4) ) = - 0.6067
