Answer:

X=11

Step-by-step explanation:

(10x+30)=140

-30 both sides

10x=110

Divide 10 both sides

X=11

x=11

------------------------------------------------------------------------------------------------------

Since 140 and 10x+30 are vertical angles, they are equal.

Equation: 140=10x+30

Subtract 30 from both sides of the equation.

140=10x

Divide both sides of the equation by 10.

You get x=10

identify the graph of 9x^2-25y^2=225 for t(0 5) and write an equation of the translated or rotated graph in general form

tamaranim1 [39]

ANSWER

The required equation is:

$9 {x}^{2} - 25{y}^{2} + 250y - 85 0=0$

EXPLANATION

The given equation is

$9 {x}^{2} - 25 {y}^{2} = 225$

Dividing through by 225 we obtain;

$\frac{ {x}^{2} }{25} - \frac{ {y}^{2} }{9} = 1$

This is a hyperbola that has it's centre at the origin.

If this hyperbola is translated so that its center is now at (0,5).

Then its equation becomes:

$\frac{ {(x - 0)}^{2} }{25} - \frac{ {(y - 5)}^{2} }{9} = 1$

We multiply through by 225 to get;

$9 {x}^{2} - 25( {y - 5})^{2} = 225$

We now expand to get;

$9 {x}^{2} - 25( {y}^{2} - 10y + 25 )= 225$

$9 {x}^{2} - 25{y}^{2} + 250y - 6 25 = 225$

The equation of the hyperbola in general form is

$9 {x}^{2} - 25{y}^{2} + 250y - 85 0=0$

adoni [48]

Answer:

The answer is 2.

Step-by-step explanation:

1- Suppose we have following array of ten integers: 5 3 8 9 1 7 0 2 6 4.

2- Before the last merge, the left half and the right half must be sorted. So it should be

1 3 5 8 9 0 2 4 6 7

Therefore the solution is 2.

fenix001 [56]

$y\cdot \:2\frac{1}{2} =$ $2\frac{1}{2}=\frac{2\cdot 2+1}{2}=\frac{5}{2}$ $=\frac{5y}{2}$

a) $2y+\frac{1}{2}=\frac{4y+1}{2}$

b) $2y+\frac{1}{2}y=\frac{5y}{2}$

4. If A is at (4, -1) and B is at (2,-7), find the midpoint of segment AB.

melomori [17]

The answer is (3,-4). On a graph you see it is right in the middle. Hope this helps.
