Contact [7]3 years ago

Answer:

Third and sixt option

Step-by-step explanation:

Applying the distributive property:

(b-2c)(-3b+c)=b(-3b)+b(c)-2c(-3b)-2c(c)

(b-2c)(-3b+c)=-3b^2+bc+6bc-2c^2

Adding like terms:

(b-2c)(-3b+c)=-3b^2+7bc-2c^2

The simplified product has 3 terms (first and second option are not true)

The simplified product has a degree of 2 (third option is true)

The simplified product, in standard form, has exactly 2 negative terms: -3b^2 and -2c^2 (sixth option is true)

Given the sequence -3, 9, -27, 81, -243, ..., find the recursive formula.
Tanzania [10]

Answer:

a_{n} = - 3a_{n-1}

Step-by-step explanation:

There is a common ratio between consecutive terms of the sequence, that is

r = 9 ÷ - 3 = - 27 ÷ 9 = 81 ÷ - 27 = - 243 ÷ 81 = - 3

The recursive formula is of the form

a_{n} = ra_{n-1} = - 3a_{n-1}

If R= {(1,2), (3,4), (5,6), (8,9)} find the domain and range of R a. Find value of X and Y.​
podryga [215]
<h2>The Domain and Range of a Set of Ordered Pairs</h2><h3>Answer:</h3>

Domain: x \in \{ 1, 3, 5, 8 \}

Range: y \in \{ 2, 4, 6, 9 \}

<h3>Step-by-step explanation:</h3>

We are given the set of ordered pairs: R. The Domain is just the set containing all the x values of each ordered pair of R. Recall that in the ordered pair (a,b), a is the x value. In set R, we can see that the x values are \{ 1, 3, 5, 8 \}.

For the Range, it is just the set containing all the y values of each ordered pair of R. Recall that in the ordered pair (a,b), b is the y value. In set R, we can see that the y values are \{ 2, 4, 6, 9 \}.
