1 answer:
mote1985 [20]3 years ago
4 0

Answer:

Choice B. only Shota

Step-by-step explanation:

16z^2 - 40z

the greatest common value is 8z

8z (2z^2 -5)

24z^2 - 40z

the greatest common value is 8z

8z (3z^2 -5)

\frac{8z (2z^2 -5)}{8z (3z^2 -5)}

8z / 8z = 1

= \frac{8z}{8z} x \frac{2z^2 -5}{3z^2 -5} = 1 x \frac{2z^2 -5}{3z^2 -5} = \frac{2z^2 -5}{3z^2 -5} (Shota)

According to the laws of exponents, you must______ the exponents when you are dividing by the same base. (Example: x^4/x^2)
prisoha [69]

Answer:

B. Subtract

Step-by-step explanation:

Just like when multiplying exponents, you're really just adding them together. This is the same case, when you're "dividing" the exponents, you're really just subtracting them.

If ethans monthly expenses are 1160 and his debt to income ratio is 0.8 what is his monthly salary
lukranit [14]

Answer:

\(1450\)

Step-by-step explanation:

Based on the given conditions, formulate: \frac{1160}{0.8}

Convert decimal to fraction:\(\dfrac{1160} {\dfrac{8}{10}}\)

Divide a fraction by multiplying its reciprocal:\(1160 \times \dfrac{10}{8}\)

Cross out the common factor: \(145 \times 10\)

Calculate the product or quotient: \(1450\)

get the result: \(1450\)

Answer: \(1450\)

In the triangle shown, let AB = DE, BC = EF, and CA = FD. Use Rigid Motions to show (triangle)ABC onto (triangle) DEF.
ki77a [65]

Answer:

Step-by-step explanation:

Given: AB≅DE, BC≅EF, CA≅FD

Since those are the given it is maped A to D, B to E, C to F

This is a rigid transformation because the distance is preserve (givens) and the triangle ABC is map to triangle DEF.

Rigid transformations produce congruent figures so triangle ABC is congruent to triangle DEF

Describe how to transform the graph of g(x)= ln x into the graph of f(x)= ln (3-x) -2.
Alenkasestr [34]

Answer:

A

Step-by-step explanation:

Note the following 3 points with respect to a function given as y = f(x).

1. The function y = f(-x) is a reflection across the y-axis

2. The function y = f(x+a) is a horizontal translation a units left and y = f(x-a) is a horizontal translation a units right

3. the function y = f(x) + a is a vertical translation a units up and y = f(x) - a is a vertical translation a units down

Dissecting the transformed function of  f(x) = ln (3-x) -2   w.r.t   f(x) = ln x, we see:

<em>1. x is replaced with -x, so </em><u><em>reflection across y-axis</em></u>

<em>2. we have a horizontal shift in left side because the argument of ln is (3-x) or (-x+3)</em>

<em>3. We have vertical shift 2 units down because there is a -2 after the functional part of ln(3-x)</em>

<em />

Looking at the choices, A is the right answer.
