Solve the Inequality and express each solution in set interval notation.

Explain how the words term and coefficient are used in talking about the algebraic expression.

cupoosta [38]

<h2>Answer:</h2>

The algebraic expressions are composed of several elements: Terms, Coefficients, Signs, Variables and Exponents. In this case we will focus on the first two.

The terms are composed of sign, coefficient, variable and exponent. The terms are separated from each other by the plus sign (+) or the minus sign (-).

For example, in the following expression:

2x-3x

We have two terms separated by the negative sign (-):

2x is the first term

-3x is the second term

Now, the coefficients are the numbers that multiply the variable. Note that if this coefficient is one (1) it is omitted .

For example in the following expression, the variable is x:

2x-3x+x

2 is the coefficient of x in the first term

-3 is the coefficient of x in the second term

1 is the coefficient of x in the third term, but is omitted

In order to understand this in a better way, see the figure attached, where the algebraic expression is composed by one term.

The area for a trapezoid is given by the formula below, where a and b are the lengths of the two bases and h is the height of th

aivan3 [116]

Answer:

C

Step-by-step explanation:

Given

A = $\frac{h(a + b)}{2}$

Substitute the given values with h = a, then

16.5 = $\frac{a(a+8)}{2}$ ( multiply both sides by 2 )

33 = a(a + 8) ← distribute

33 = a² + 8a ( subtract 33 from both sides )

0 = a² + 8a - 33 ← in standard form

0 = (a + 11)(a - 3) ← in factored form

Equate each factor to zero and solve for a

a + 11 = 0 ⇒ a = - 11

a - 3 = 0 ⇒ a = 3

However, a > 0 thus a = 3

Hence the height is 3 feet

Helga [31]

Answer:

Self selection sampling.

Step-by-step explanation:

A poll that does not attempt to generate a random sample, but instead invites people to volunteer to participate is called - self selection sampling.

Self-selection sampling is a sampling method where researchers allow the people or individuals, to choose to take part in research on their own accord.
