Answer:

-3/10

Step-by-step explanation:

3/2 is equivalent to 15/10. Or 1 5/10. And 6/5 is equivalent to 18/10s or 1 8/10. Therefore 1 1/5 + (-1 8/10) = -3/10

Step-by-step explanation:

Answer:

Step-by-step explanation:

2x + 5y = 1     ⇒    2x = 1 - 5y

y = 2xy + 5

y = (1 - 5y)y + 5

y = y - 5y² + 5

5y² = 5

y² = 1

 y₁ = 1               ∨           y₂ = -1

2x₁ = 1 -5(1)                   2x₂ = 1 - 5(-1)

2x₁ = 1 - 5                      2x₂ = 1 + 5

2x₁ = -4                         2x₂ = 6

 x₁ = -2                           x₂ = 3

Midpoint:

[tex]M=\left(\frac{x_1+x_2}2\ ,\ \frac{y_1+y_2}2\right)=\left(\frac{-2+3}2\ ,\ \frac{1+(-1)}2\right)=\left(\frac12\ ,\ 0\right)[/tex]

The coordinates of the midpoint of the line AB is (0, 1/2).

The equation of the curve is given by y = 2xy + 5.

The equation of the line is given by 2x + 5y = 1.

We have to first find the point of intersection between the curve and the line and then find the coordinates of the midpoint of line AB where A and B is the point of intersection between the curve and the line.

If C(x, y) divides a line AB in m:n then we have,

[tex]x = \frac{mx_2 +nx_1}{m+n},~~~y =\frac{my_2+ny_1}{m+n}[/tex]

And if C(x,y) is the midpoint then m = n.

we have,

[tex]x = \frac{x_2 +x_1}{2},~~~y =\frac{y_2+y_1}{2}[/tex]

Where x and y are the coordinates of the midpoint o the line AB.

Find the point of intersection between the line and the curve.

y = 2xy + 5............(1)

2x + 5y = 1..............(2)

From (2) we have,

2x = 1 - 5yx = (1-5y) / 2..........(3)

Substituting (3) in (1).

[tex]y =2\frac{(1-5y)}{2}y + 5\\\\y =\frac{2y-10y^2}{2} + 5\\\\2y = 2y - 10y^2 + 10\\\\10y^2 = 10\\\\y^2 = 1[/tex]

So we have,

y = 1 and y = -1

Puttin y = 1 in (3) we get,

x = (1 - 5) / 2 = - 4 / 2 = -2

Puttin y = -1 in (3) we get,

x = {1-5(-1)} / 2 = (1+5) / 2 = 6 / 2 = 3

Now we have two points of intersection A( 1, -2 ) and B( -1, 3 ).

Finding the coordinates of the midpoint of the line AB.

we have,

[tex]A(1, -2) = A (x_1, y_1)~~and~~B(-1, 3) = B(x_2, y_2)[/tex]

Substituting in the given equation.

[tex]x = \frac{x_2 +x_1}{2},~~~y =\frac{y_2+y_1}{2}\\\\x = \frac{-1 +1}{2},~~~y =\frac{3+(-2)}{2}\\\\x = 0,~~~y=\frac{1}{2}[/tex]

So the coordinates of the midpoint is (x,y) = ( 0, 1/2 ).

Step-by-step explanation:

bassically what you do is add 7 dollars to the ninety six that she lost when she bought the pie or you can do this equation 96 + m but m would be the money she lost being 7 dollars so you would replace m with 7 so it would be 96 + 7 = 103

Answer:

bus = 50mph and train = 70mph

Step-by-step explanation:

4b + 4t = 480

t = b + 20 [replace the "t" in the next step to solve]

4b + 4(b + 20) = 480

4b + 4b + 80 = 480

8b + 80 = 480 [subtract 80 from both sides of the equation]

8b = 400 [divide by 8 on both sides of the equation]

b = 50 and if the train is 20mph faster, t = 70

4(50) + 4(70) = 480

Answer:

3

Step-by-step explanation:

To find the slope of a line going through two points, (x₁, y₁) and (x₂, y₂), we can use the following formula: [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]. Note that it doesn't really matter which points we call (x₁, y₁) or (x₂, y₂).

Let's call (x₂, y₂) = (0, 5) and (x₁, y₁) = (-2, -1). Now, we can plug in the values for x, y₁, x₂, and y₂ into the formula.

We have:

[tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }=\frac{5-(-1)}{0-(-2)} =\frac{5+1}{0+2} =\frac{6}{2} =3[/tex]

Therefore, the slope of the line is 3. Hope this helps!

[tex]\large\boxed{\pink{ \leadsto The \ given \ equation \ is \ not \ a \ Quadratic \ equation . }}[/tex]

Step-by-step explanation:

Given equation to us is ,

[tex]\green{\implies x^2+\dfrac{1}{x}=4 }[/tex]

So , a equation is said to be a quadratic equation if the highest degree of the variable is 2 . On simplifying the Equation ,

[tex]\implies x^2 +\dfrac{1}{x}=4 [/tex]

Taking x as LCM ,

[tex]\implies \dfrac{x^2.x + 1 }{x}= 4 [/tex]

Transposing x to RHS .

[tex]\implies x^3 + 1 = 4x [/tex]

Putting all terms in LHS

[tex]\boxed{\bf \implies x^3 - 4x - 1 = 0 }[/tex]

Since here the highest degree of the variable is 3 not 2 . So its a cubic equation and not a quadratic equation .

Answer:

Option (3)

Step-by-step explanation:

Given inequality is,

-2x + 8 < 12

By subtraction property of Order,

-2x + 8 - 8 < 12 - 8

-2x < 4

B division property of Order,

[tex]\frac{-2x}{(-2)}<\frac{4}{(-2)}[/tex]

x > -2

Since, there is no sign of equal to ( = ) in the given inequality, starting point on a number line will be a hollow point.

And an arrow starting from point x = -2 directing towards positive integers will represent the given inequality.

Option (3) will be the answer.

Answer:

The equation becomes

[tex]1\frac{7}{19}=a\frac{b}{c}[/tex]

Therefore,

Hence, option (C) is true.

Step-by-step explanation:

Given the expression

[tex]3\frac{1}{4}\div 2\frac{3}{8}\:=a\frac{b}{c}[/tex]

Solving the L.H.S of the equation

[tex]3\frac{1}{4}\div \:2\frac{3}{8}=\frac{13}{4}\div \:2\frac{3}{8}[/tex]

               [tex]=\frac{13}{4}\times \frac{8}{19}[/tex]

               [tex]=\frac{13\times \:2}{1\times \:19}[/tex]

                [tex]=\frac{26}{1\times \:19}[/tex]

                 [tex]=\frac{26}{19}[/tex]

Converting improper fraction to a fixed number: [tex]\frac{26}{19}=1\frac{7}{19}[/tex]

                 [tex]=1\frac{7}{19}[/tex]

Thus, the equation becomes

[tex]1\frac{7}{19}=a\frac{b}{c}[/tex]

Therefore,

Hence, option (C) is true.
