What is the simplest form of the expression (–11.7y – 3.3x) + 1.2x + (5.2y + x)? –16.9y – 5.5x –16.9y – 4.5x –6.5y – 2.1x –6.5y – 1.1x

Answers

Answer 1

Answer:

Answer:

(D) $-6.5y-1.1x$

Step-by-step explanation:

The given expression is:

$(-11.7y-3.3x)+1.2x+(5.2y+x)$

Upon simplifying the above equation, we get

$-11.7y-3.3x+1.2x+5.2y+x$

Rewriting the above expression by writing the like terms together, we have

$-11.7y+5.2y-3.3x+1.2x+x$

Solving the like terms, we get

$-6.5y-1.1x$

which is the required simplified form of the given expression..

Hence, option (D) is correct.

Choose one of the factors of x6 + 1000x2

x2 – 10

x4 – 10x2 + 100

x4 + 10x2 + 100

Answers

There are lot of possible factors. One possible factor that is in choices is x2. This is done using elimination process of choices because there are a lot of factors, x2 - 10 is not possible because x^6 is only 1. Then the other 2 is impossible since they still uses 10x2

PLEASE HELP !!!!!!!!!!!!!!!!!2. Circle P has center P(2, 0) and radius 20. Circle Q has center Q(0, 4) and radius 2.
(a) Describe the rule for translating center Q onto center P.
(b) Determine the scale factor for dilating circle Q so that it has the same radius as circle P.
(c) Are circles P and Q similar? Explain your answer.

Answers

(a) Describe the rule for translating center Q onto center P.
center P(2, 0)
center Q(0, 4)
you would need to add 2 units in x axis, and subtract 4 units on y axis.

(b) Determine the scale factor for dilating circle Q so that it has the same radius as circle P.
P radius 20, Q radius 2, radiusQ*10 = radiusP, so the scale factor is 10

(c) Are circles P and Q similar? Explain your answer.
they are similar because a similarity transformation (translation, dilation) exists between them
