Answer:

Step-by-step explanation:

y=0.23x+1

f(2)=0.23(2)+1=0.46+1=1.46

f(0)=0.23(0)+1=0+1=1

f(-3)=0.23(-3)+1=-0.69+1=0.31

What is the value of f^-1(-3)?

poizon [28]

Flip the curve over y = x then observe what is y when x = -3. You will find that $f^{-1}(x)=1.5$ .

Hope this helps.

Write the equation in standard form for the circle with center (0, 9) passing through (0, 27/2)

sammy [17]

Given

coordinates of center= (0,9)

Circle passes through (0, 27/2)

Find

Equation of circle

Explanation

The equation of circle in standard form is

$\begin{gathered} (x-h)^2+(y-k)^2=r^2 \\ (x-0)^2+(y-9)^2=r^2 \end{gathered}$

We know the circle passes through (0,27/2), then

$\begin{gathered} (0-0)^2+(\frac{27}{2}-9)^2=r^2 \\ r=4.5 \end{gathered}$

So the equation in the standard form is

$(x-0)^2+(y-9)^2=4.5^2$

Final Answer

$(x-0)^2+(y-9)^2=4.5^2$

Destiny has 10$ and Elijah has 5$. I give each person the same amount of money each week. This situation can be represented with

Darina [25.2K]

Answer:

I do believe that the answer is 0 solutions.

Step-by-step explanation:

x+10 =x+5

Subtract 5 from both sides, you get:

x+5=x

Subtract x from both sides, and you get:

5=0 which is NOT true. Also I maybe wrong, pls don't be mad at me.

A rectangular photograph is surrounded by a border that is 1 inch wide on each side. The total area of the photograph and the bo

My name is Ann [436]

if 1 inch is added, you would add 2 inches to to each side of rectangle.

You would have: W+2, and, L+2,

Now let W+2 = x and, L+2 = y

Total area = x*y=M

If 1 inch is added again, like above you add 2 inches to both sides, you would then have:

(x+2)(y+2)=M+52;

xy+2x+2y+4=M+52;

xy=M

2x+2y=48

x+y=48/2=24

Now solve :

W+2+ L+2=24

W+L=20

The perimeter is 2(W+L)=20*2 = 40 inches.
