Answer:

Terms are 7x, 4y, 1

Step-by-step explanation:

We define the term algebraic as an algebraic expression that has been reduced and where there is no addition or subtraction between the variables.

Algebraic terms are characterized as product expressions of coefficient (s) by the variable (s) or literal part.

Algebraic terms are represented by the following parts: coefficients, variables, exponents and the literal part.

However, there are terms that may not have any part, such as the literal.

Let F(x)=3x-1 and g(x)=×+2. Findf(g(x)) and g(f(x))

Fofino [41]

Solution:

Given:

$\begin{gathered} f(x)=3x-1 \\ g(x)=x+2 \end{gathered}$

To find f(g(x)):

$\begin{gathered} f(g(x))\text{ means substitute g\lparen x\rparen into f\lparen x\rparen} \\ f(g(x))=3(x+2)-1 \\ f(g(x))=3x+6-1 \\ f(g(x))=3x+5 \end{gathered}$

Therefore, f(g(x)) = 3x + 5

To find g(f(x)):

$\begin{gathered} g(f(x))\text{ means substitute f\lparen x\rparen into g\lparen x\rparen} \\ g(f(x))=(3x-1)+2 \\ g(f(x))=3x-1+2 \\ g(f(x))=3x+1 \end{gathered}$

Therefore, g(f(x)) = 3x + 1

Find the area of the trapezoid.

Usimov [2.4K]

Answer:

$\large\boxed{A=54\ m^2}$

Step-by-step explanation:

The formula of an area of a trapezoid:

$A=\dfrac{b_1+b_2}{2}\cdor h$

b₁, b₂ - bases

h - height

We must use the Pythagorean theorem:

$x^2+8^2=10^2$

$x^2+64=100$ subtract 64 from both sides

$x^2=36\to x=\sqrt{36}\\\\x=6\ m$

We have b₁ = 6 + 6 = 12m, b₂ = 6m and h = 8m.

Substitute:

$A=\dfrac{12+6}{2}\cdot6=\dfrac{18}{2}\cdot6=(9)(6)=54\ m^2$

Evaluate the following expression. 5^-3

Ulleksa [173]

5^-3 is 1/125

The negative in the exponent makes it so there is a 1 over the problem if there was no negative. When you have a negative in the exponent, the answer will be the reciprocal (opposite) of the question with no negative.
For example,

9^2 = 81

9^-2 = 1/81
