Answer: y = 2 and x = 2

Step-by-step explanation:

[tex]9x^2+4(y-2)^2=36\\x^2=2y[/tex]

First, get the entire thing in terms of y, because you cant solve for two variables at the same time. They gave us the fact that x^2 = 2y

[tex]9(2y)+4(y-2)^2=36\\18y+4(y^2-4y+4)=36\\18y+4y^2-16y+16=36\\4y^2+2y-20=0[/tex]

What two numbers multiply to equal -80 but add to equal 2? That is +10 and -8.

[tex]4y^2+2y-20=0\\(4y^2-8y)+(10y-20)=0\\4y(y-2)+10(y-2=0)\\(4y+10)(y-2)=0\\y=-5/2\\y=2[/tex]

Now solve for x by plugging in y to the easier equation

[tex]x^2=2(-5/2)\\x\neq \sqrt{-5}[/tex]

If I didn't make a mistake, this should be the only answer. In the case of y = -5/2, you would get an imaginary x-value. Therefore y cannot equal -5/2

[tex]x^2=2(2)\\x=2[/tex]

The solution of the expression are,

x = 2.28 , y = 2.62

Or, x = 3.9i , y = - 7.62

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The system of equations are,

9x² + 4 (y - 2)² = 36  .. (i)

x² = 2y  .. (ii)

Substitute the value of x² from (ii) in (i);

9x² + 4 (y - 2)² = 36

9 × 2y + 4 (y - 2)² = 36

18y + 4 (y - 2)² = 36

9y + 2 (y - 2)² = 18

9y + 2 (y² + 4 - 2y) = 18

9y + 2y² + 8 - 4y = 18

2y² + 5y + 8 - 18 = 0

2y² + 5y - 10 = 0

y = - 5 ± √5² - 4×2×- 10 / 2×2

y = - 5 ± √ 25 + 80 / 2

y = - 5 ± √ 105 / 2

y = - 5 ± 10.24 / 2

y = - 5 + 10.24 / 2

y = 5.24/2

y = 2.62

y = - 5 - 10.24 / 2

y = - 15.24 / 2

y = - 7.62

From (ii);

x² = 2y

x² = 2 × 2.62

x² = 5.24

x = 2.28

x² = 2y

x² = 2 × - 7.62

x² = - 15.24

x = 3.9i

Thus, The solution of the expression are,

x = 2.28 , y = 2.62

Or, x = 3.9i , y = - 7.62

Answer:

[tex]\frac{-24p + 5}{30p}[/tex]

Step-by-step explanation:

Did you mean to add the terms.  You can only solve equations or inequalities and this is an expression.  Assuming you are to add the terms, then the lowest common denominator is 30p

So,  [tex]\frac{-2(10)}{3p(10)} + \frac{6p}{5(6p)} - \frac{30p}{30p} + \frac{5(5)}{6p(5)}[/tex]

=  [tex]\frac{-20 + 6p - 30p + 25}{30p}[/tex]

=  [tex]\frac{-24p + 5}{30p}[/tex]

Answer:

( 10,-7)

i didn't understand what u wrote in choice

The coordinates of the point S of the line RS having midpoint T are found to be (10, -7).

In geometry, the midpoint is the middle point of a line segment. It is equidistant from both endpoints, and it is the centroid both of the segment and of the endpoints. It bisects the segment.

here, we have,

The points that are given to us are R(-2,3) and T(4, -2).

The point T is the mid point of the line segment RS.

If A(a, b) and B(c, d) are the two points then the mid point M of the two points will be,

M = ((a+c)/2), ((b+d/2))

So, using the above modified form of section formula we can find the coordinates of the point S.

Assuming point S to be x and y.  

So, putting all the values,

(4, -2) = ((-2+x)/2), ((3+y/2))

Now, solving further, we get,

-1+x/2 = 4

-2+x = 8

x = 10

And,

3 + y = -4

y = -7

So, the coordinates are (10, -7).

The highest price per pizza in a profit of $100 is approximately $15.48

The profit equation is given by:

p = -5 [tex]x^2[/tex]  + 100x - 250

Substitute p = 100 and solve for "x":

100 = -5 [tex]x^2[/tex]+ 100x - 250

To solve this quadratic equation, it can be rearranged it to standard form [tex](ax^2 + bx + c = 0)[/tex]

[tex]5x^2- 100x + 350 = 0[/tex]

Now, we can solve the quadratic equation using the quadratic formula:

[tex]x = \dfrac{(-b\pm \sqrt ({b^2 - 4ac)}}{2a}[/tex]

In our equation, a = 5, b = -100, and c = 350. Substitute these values into the formula:

x =[tex]\frac{(\sqrt{(-100)^2 - 4 \times 5 \times 350}}{2\times5}[/tex]

x= [tex]\dfrac{{100 \pm\sqrt{3000}}}{10}[/tex]

Thus, the two possible solutions for "x":

[tex]x_1[/tex] =[tex]\dfrac{100 + \sqrt{3000}}{10}[/tex]

[tex]x_2[/tex] =[tex]\dfrac{100 - \sqrt{3000}}{10}[/tex]

Calculating the values:

[tex]x_1[/tex]≈ 15.48

[tex]x_2[/tex] ≈ 4.23

The highest price per pizza that results in a profit of $100 is approximately $15.48 (rounded to two decimal places).

Let's solve your equation step-by-step:

6(y+6)=3y−33

Step 1: Simplify both sides of the equation

6(y+6)=3y−33

(6)(y)+(6)(6)=3y+−33(Distribute)

6y+36=3y+−33

6y+36=3y−33

Step 2: Subtract 3y from both sides

6y+36−3y=3y−33−3y

3y+36=−33

Step 3: Subtract 36 from both sides

3y+36−36=−33−36

3y=−69

Step 4: Divide both sides by 3.

3y/3=−69/3

y=−23
