Answer:

y = -1/2x + 5

It will take 10 weeks for the cat to lose 5 pounds.

Step-by-step explanation:

<u>Find slope</u>

Take 2 points (2,4) (6,2)

  • y2 - y1/x2 - x1
  • 2 - 4/6 - 2

slope = -1/2

<u>y-intercept</u>

(0,5)

<u>y = mx + b form</u>

m represents slope

b represents y-intercept

y = -1/2x + 5

<u>Find the number of weeks it will the cat to lose 5 pounds</u>

Set y = to 0, to find when the cat loses weight

0 = -1/2x + 5

<u>Subtract 5 in both sides</u>

-5 = -1/2x

<u>Isolate the variable by getting rid of the denominator</u>

-1/2x * 2 = -x

2 * - 5 = -10

<u>Simplify</u>

-x = -10

<u>Divide both sides by -1</u>

-x/-1 = x

-10/-1 = 10

<u>Simplify </u>

x = 10

<u>Answer</u>

Answer:

y = -1/2 x +5

10 weeks

Step-by-step explanation:

The y intercept is 5  ( That is is the point where x=0)

Our slope is rise over run  or 1 lb /2 weeks

We know this is negative because the cat is losing the weight

slope = -1/2

The equation in slope intercept form is

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

y = -1/2 x +5

We need to determine when y=0 to find when the cat loses all 5 lbs

0 = -1/2 x +5

Subtract 5 from each side

0-5 = -1/2x +5-5

-5 = -1/2x

Multiply each side by -2 to get x alone

-5 *-2 = -1/2x * -2

10 = x

It will take 10 weeks

Answer:

7.1 (7.06 rounded to the tenth)

Step-by-step explanation:

The formula for Area of a Circle is: π·r²

R = Radius

π = pi, or 3.14

As long as you know the formula, this is easy!

In class, you may have already been told that the radius is <em>half </em>of the diameter.

1. Half of 3 ft is 1.5 ft.

2. Plug 1.5 in for r, in your calculator

3. Do the calculation, and you should come out to get 7.06858347058

4. Round it!

Finding area for a circle is satisfying, isn't it? xD

What's X? to: <br> 15x - 7x = (-52) - 5x
Studentka2010 [4]
-4

Because 15x-7x= 8x
8x+5x= 13x
13x= -52
-52 / 13= -4
x = -4

Find the Y-coordinate of point P that lies 1/3 along segment RS, where R (-7, -2) and S (2, 4).
QveST [7]

Solution:

Given that the point P lies 1/3 along the segment RS as shown below:

To find the y coordinate of the point P, since the point P lies on 1/3 along the segment RS, we have

\begin{gathered} RP:PS \\ \Rightarrow\frac{1}{3}:\frac{2}{3} \\ thus,\text{ we have} \\ 1:2 \end{gathered}

Using the section formula expressed as

[\frac{mx_2+nx_1}{m+n},\frac{my_2+ny_1}{m+n}]

In this case,

\begin{gathered} m=1 \\ n=2 \end{gathered}

where

\begin{gathered} x_1=-7 \\ y_1=-2 \\ x_2=2 \\ y_2=4 \end{gathered}

Thus, by substitution, we have

\begin{gathered} [\frac{1(2)+2(-7)}{1+2},\frac{1(4)+2(-2)}{1+2}] \\ \Rightarrow[\frac{2-14}{3},\frac{4-4}{3}] \\ =[-4,\text{ 0\rbrack} \end{gathered}

Hence, the y-coordinate of the point P is

Answer:

x=5 y=-6

Step-by-step explanation:

3x+y=9 ------eqn1

y=4-2x -------eqn2

using substitution

put y=4-2x into eqn1

3x+4-2x=9

x=5

put x=5 into eqn2

y=4-2(5)

y=4-10

y=-6
