Put the following equation of a line into slope-intercept form, simplifying all

Mathematics

Answer:

y = -x - 3

Step-by-step explanation:

We are trying to get the equation 3x + 3y = -9 into the form y = mx+b, aka slope-intercept form.

To do this we are trying to isolate y.

3x + 3y = -9

Subtract 3x from both sides:

3y = -9 - 3x

Rearrange the terms:

3y = -3x - 9

Divide both sides by 3:

y = -x - 3

Hope this helped!

Answer:

<em>Answer is</em><em> </em><em>330</em>

Step-by-step explanation:

area \: of \: shaded \: region \:  = \pi {r}^{2}  - \pi( {x}^{2}  \\ here \: r = 11 \: cm \: and \: x = 4 \: cm \\ area \: of \: a \\ shaded \: regoin \:  = \pi( {r}^{2} -   {x}^{2} ) \\  = \pi( {11}^{2}  -  {4}^{2} ) \\  = \pi(121 - 16) \\  = \pi(105) \\  =  \frac{22}{7}  \times 105 \\  = 22 \times 15 \\  = 330  \: {cm}^{2}

<em>AREA</em><em> </em><em>OF</em><em> </em><em>SHADED</em><em> </em><em>REGION</em><em> </em><em>=</em><em>330</em>

one number is equal to the square of another. find the numbers if both are positive and their sum is 1122
statuscvo [17]

Answer:

One number is 561

The other number is 23.6854

Step-by-step explanation:

x = y^2                One number = the square of another

x + y^2 = 1122     The sum of the two numbers is 1122

Substitute y^2 in for x on the second equation.

y^2 + y^2 = 1122    Combine like terms on the left

2y^2 = 1122            Divide by 2

y^2 = 1122/2

y^2 = 561                Take the square root of both sides.

y = 23.6854            

x = y^2

x = 561

y^2 = 561
