Mathematics
1 answer:
Anastaziya [24]3 years ago
6 0

Answer:

\huge{k( - 2)} = 3

Step-by-step explanation:

K(x)= -3x - 3

To find the value of k substitute the value of k that's -2 into the original expression and solve for the value of k.

That's

k( - 2) =  - 3( - 2) - 3 \\  = 6 - 3 = 3

We have the final answer as

<h3>k(-2) = 3</h3>

Hope this helps you

Find the common ratio for the following geometric sequence. 0.75,1.5,3,6,...
Rasek [7]

Answer:

<h2>2</h2>

Step-by-step explanation:

\text{If}\ a_1,\ a_2,\ a_3,\ a_4,\ ...\ ,\ a_n\ \text{is a geometric series, then}\\\\\dfrac{a_2}{a_1}=\dfrac{a_3}{a_2}=\dfrac{a_4}{a_3}=...=\dfrac{a_n}{a_{n-1}}=r=constant

\text{We have}\ 0.75,\ 1.5,\ 3,\ 6,\ ...\\\\\text{The common ratio}\ r:\\\\\dfrac{1.5}{0.75}=2\\\\\dfrac{3}{1.5}=2\\\\\dfrac{6}{3}=2\\\\\boxed{r=2}

Should it be facing left or right ?
riadik2000 [5.3K]

Answer:

Facing Right

Step-by-step explanation:

Given inequalities are:

4-x≤-1

Subtracting 4 from both sides

4-x-4≤-1-4

-x≤-5

Multiplying both sides with -1. Multiplying with a negative number changes the sign of the inequality

So,

x≥5

Second Inequality:

2+3x≥17

Subtracting 2 from both sides

2+3x-2≥17-2

3x≥15

Dividing both sides by 3

x≥5

Union of both solutions:

x≥5 ∩ x≥5

=> x≥5

Hence the solution will be facing right on the number line towards all numbers greater than or equals to 5 ..
