What is the slope of the line whose equation is 2x+3y = -12?

Answers

Answer:

slope = - [tex]\frac{2}{3}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

2x + 3y = - 12 ( subtract 2x from both sides )

3y = - 2x - 12 ( divide all terms by 3 )

y = - [tex]\frac{2}{3}[/tex] x - 4 ← in slope- intercept form

with slope m = - [tex]\frac{2}{3}[/tex]

The Lucas numbers are defined by the recursive formula t1 = 2, t2 = 1, tn = tn - 1 + tn - 2, where n âN and n > 2. What are the first 9 Lucas numbers?

Answers

The first two are given to you, [tex]t_1=2[/tex] and [tex]t_2=1[/tex]. Use the recursive formula to get the 3rd term; then use the 2nd and 3rd terms to get the 4th; and so on.

Since the n-th Lucas number is the sum of the previous two Lucas numbers, you have

[tex]t_3 = t_2 + t_1 = 1 + 2 = 3[/tex]

[tex]t_4 = t_3 + t_2 = 1 + 3 = 4[/tex]

[tex]t_5 = t_4 + t_3 = 4 + 3 = 7[/tex]

[tex]t_6 = t_5 + t_4 = 7 + 4 = 11[/tex]

[tex]t_7 = t_6 + t_5 = 11 + 7 = 18[/tex]

[tex]t_8 = t_7 + t_6 = 18 + 11 = 29[/tex]

[tex]t_9 = t_8 + t_7 = 29 + 18 = 47[/tex]

Answer:

Since +P looks to be 7, -P would be -7

Hope this helps :)

Answer:

-7

Step-by-step explanation:

P is a variable, and P can only have 1 value. Thanks to the number line, we know what this value is. P is positive 7. If we know that the set value of P is positive 7, then we can just treat it like it is positive 7.

P - 5 = 2

P + 3 = 10

So putting a negative sign in front of P will mean it will be

Step-by-step explanation:

Sum: 6 * 10^-4 + 1.5*10^-4 = 7.5 * 10^-4

Difference: 6 * 10^-4 - 1.5 * 10^-4 = 4.5 * 10^-4

Product: 6*10^-4 * 1.5 * 10^-4 = 9 * 10^-8

Quotient: 6*10^-4/1.5 * 10^-4 = 4

Notice the answers, because they give you the rules.

When adding exponents and rationales, if the powers are the same then the rationales merely add.

Same rule applies to subtraction. Retain the powers and subtract the rationales.

When multiplying the rationales multiply, but the rationales add. they don't stay the same.

When dividing, the rationales divide and the powers subtract -- numerator minus denominator

Step-by-step explanation:

5.04 is the answer.

Answer:

Answer B is correct

Step-by-step explanation:

We want to multiply 6 and 0.84

First you have to forget about decimals and multiply those two numbers

084

   ×6

-----------------

 =  504

And then consider about the number of decimal places. According this sum you have 2 decimal places ( 0.84 )

And now you can write the answer as

= 5.04
