It says decreasing so you have to turn it into a percent (.06%) and then sub tract that from 1. After that you put that into an equation.

Answer:

a. -3

Step-by-step explanation:

-2 turns into 6 by multiplying it by -3.

the same from 6 to -18, from -18 to 54, ...

so, an/an+1 = -3

HELP ITS ABOUT POINTS AND EQUATIONS AND WHAT THE PERSON FAILED IN DOING EXPLANATION NEEDED PLEASE

katen-ka-za [31]

Answer:

see below

Step-by-step explanation:

First find the slope

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

= (-5- -7.5)/ ( 2 - -3)

= (-5+7.5) / ( 2+3)

= 2.5 /5

=1/2

Then using the slope intercept equation of a line

y = mx+b where m is the slope and b is the y intercept

y = 1/2x+b

Using a point from above

-5 = 1/2(2) +b

-5 =1+b

Subtract 1 from each side

-6 = b

We have the y intercept

y = 1/2x-6

Tahlia forget to find the y intercept for the equation

How do you graph a circle x^2 + y^2=25 and the line is given y=2

Kazeer [188]

$\bf \textit{equation of a circle}\\\\ 
(x-{{ h}})^2+(y-{{ k}})^2={{ r}}^2
\qquad 
\begin{array}{lllll}
center\ (&{{ h}},&{{ k}})\qquad 
radius=&{{ r}}
\end{array}\\\\
-------------------------------\\\\
x^2+y^2=25\implies (x-0)^2+(y-0)^2=5^2$

so notice above, the circle is centered at h,k or 0,0, the origin, and has a ratio of 5.

and y = 2, is just a horizontal line, check the picture below.

Mary owned n sheep and Sam had exactly 4 times as many sheep as Mary.

Veseljchak [2.6K]

Answer:

The least value of n is, 9.

Step-by-step explanation:

Mary(M) owned the number of sheep is n i.e, M = n sheep

Sam(S) had exactly four times as many sheep as Mary , i.e, S = 4 n sheep

As per the given condition Mary buys 17 extra sheep

Now, Mary has total number of sheep, M = n +17 sheep

And Sam sells 8 of his sheep that means he has now,

But, Sam still has more sheep than Mary i.e,

Solve an inequality:

Add 8 both sides we get;

Simplify:

Now, subtract n from both the side, we get;

Simplify:

or

Since n is the number of sheep in integer,

then the least value of n is, 9.
