Answer:

y = -4x+1

Step-by-step explanation:

slope = (y2-y1)/ (x2-x1)

m= (-3-5)/(1--1)

= (-3-5)/(1+1)

= -8/2

= -4

point slope form of a line is

y-y1 = m(x-x1)

y-5 =-4(x--1)

y-5 = -4 (x+1)

distribute

y-5 = -4x -4

add 5 to each side

y-5+5 = -4x-4+5

y = -4x+1

I just need help explaining it. solve the system of equation

Maksim231197 [3]

SOLUTION

Write out the equation

$\begin{gathered} y=\frac{1}{3}x-3 \\ 5x-3y=-3 \end{gathered}$

To solve this system of equation, the aprropriate method will be substitution

Substitute the expression for y into the second equation for y, we have

$5x-3(\frac{1}{3}x-3)=-3$

Expand the paranthesis we have

$\begin{gathered} 5x-x+9=-3 \\ \text{Simplify},\text{ by subtracting 9 from both sides } \\ 4x+9-9=-3-9 \\ 4x=-12 \end{gathered}$

Divide both sides by 4, we have

$\begin{gathered} \frac{4x}{4}=-\frac{12}{4} \\ \text{Then} \\ x=-3 \end{gathered}$

Since the value of x has been obtained, we substitute into the first equation

$\begin{gathered} y=\frac{1}{3}x-3 \\ \text{ recall x=}-3 \\ y=\frac{1}{3}(-3)-3 \\ y=-1-4 \\ \text{Hence } \\ y=-4 \end{gathered}$

Therefore

x = -3, y= -4

Show and explain how you found the answer to this problem. Marion read 616 pages in 14 days. If she read the same number of page

Pepsi [2]

Based on the number of pages read and the time it was read in, the number of pages read per day was 44 pages. 

Marion read 616 pages and did this in 14 days.

She read the same number of pages each day so the number of pages read per day was:

= Number of pages read in total / Number of days

= 616 / 14

= 44 pages

In conclusion, she read 44 pages per day.

Answer:

P(N = n) = $(1-P)^{n-1} \times P$

Step-by-step explanation:

to find out

Find the PMF PN (n)

solution

PN (n)

here N is random variable

and n is the number of times

so here N random variable is denote by the same package that is N (P)

so here

probability of N is

P(N ) = Ф ( N = n) .................. 1

here n is = 1, 2,3, 4,...................... and so on

so that here P(N = n) will be

P(N = n) = $(1-P)^{n-1} \times P$

Answer:

If 1/4 of the gas tank is filled, then there are 5 gallons currently in the gas tank.

If 10 gallons are added to the gas tank, there will be 15 gallons in the gas tank, meaning that the gas tank will be 3/4 full.
