Y=-6x-15. You do -6*-2 which is 12. And ti get to -2 you have to subtract -15. So it is y=-6x-15

Answer:

Equation of line is 6x + y = -15

Step-by-step explanation:

Equation of line passing through (x₁,y₁) and with slope m is given by

y - y₁ = m ( x - x₁ )

Here (x₁,y₁) = (-2,-3)

Slope, m = -6

Substituting

y - y₁ = m ( x - x₁ )

y - (-3) = -6 ( x - (-2) )

y + 3 = -6 ( x + 2 )

y + 3 = -6 x - 12

6x + y = -15

Equation of line is 6x + y = -15

In the last 10 years, the population of Indonesia has grown at a rate of 1.12% per year to 258,316,051. If this rate continues,

Reptile [31]

Answer:

Final population after 10 years

= 288911718

Step-by-step explanation:

Present population p = 258,316,051

Rate of growth R%= 1.12%

Number of years t= 10 years

Number of times calculated n = 10

Final population A

= P(1+r/n)^(nt)

A= 258,316,051(1+0.0112/10)^(10*10)

A= 258,316,051(1+0.00112)^(100)

A= 258,316,051(1.00112)^100

A= 258,316,051(1.118442762)

A= 288911717.6

Approximately A= 288911718

Final population after 10 years

= 288911718

Solve the equation 9x+16=5 for y

dezoksy [38]

Answer:

-11/9 or -1.2222222222

Step-by-step explanation:

9x+16= 5

-16 -16

9x= -11

9x ÷9 and -11÷9

x= -11/9 or -1.2222222222

You flip a coin 100 times in the air and find that it lands on heads 65 times. Determine the theoretical and experimental probab

scoundrel [369]

Answer:

The experimental probability --> $\frac{13}{20}$

The theoretical probability --> $\frac{1}{2}$

Step-by-step explanation:

Key skills needed: Experimental vs theoretical probability, Fractions

1) The first thing you need to understand is experimental probability vs theoretical probability. (Do not include this in your work!!)

- Theoretical probability is based on simple reasoning

- Experimental probability is based on the results a person gets (so the experiment you did by flipping the coin)

2) Now with this, let's start solving:

Experimental probability ---> $\frac{heads}{total}$ --> You flipped the coin a total of 100 times, so the denominator would be 100. 65 of those would be heads so 65 is our numerator.
So our experimental probability is --> $\frac{65}{100}$ --> Both have the factor of 5, so take the factor of 5 out of the numerator and denominator and you will get --> $\frac{13}{20}$
Now onto theoretical probability --> $\frac{heads}{total}$ --> There are 2 faces of a coin, 1 side is heads, and 1 side is tails --> The total number of faces is 2, so 2 is our denominator. There is only 1 side that is heads, so 1 is the numerator. This means --> Our theoretical probability is $\frac{1}{2}$

Hope you understood and have a nice day!! :D
