What is the value of a for the following circle in general form?
X^2+y^2+ax+by+c=0​

Answer:

Step-by-step explanation:

If -3/2 and 5 are solutions to the quadratic equation, hence the expression will give;

(x-(-3/2))(x-5) = 0

(x+3/2)(x-5) = 0

Compare the resulting expression with (ax+b)(x+c)=0, we can see that;

ax = x

divide both sides by x

ax/x = x/x

a = 1

b = 3/2

-5 = +c

c = -5

Hence a = 1,  = 3/2 and c = -5

Answer:

A''(3/2, -3)

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, dilation and rotation.

If a point A(x, y) is reflected over the x axis, the new point would be A'(x, -y).

If a point A(x, y) is dilated by a factor k, the new point would be A'(kx, ky).

Given that Trapezoid QUAD has vertices at Q(-4, 0), U(-2, 4), A(2, 4) and D(4, 0).  If the trapezoid is reflected over the x-axis to create trapezoid  Q'U'A'D', the vertices would be at Q'(-4, 0), U'(-2, -4), A'(2, -4) and D'(4, 0).

If trapezoid Q'U'A'D'is dilated by a factor of 3/4  respect to the origin to create trapezoid Q"U"A"D", the vertices would be at Q''(-3, 0), U''(-3/2, -3), A''(3/2, -3) and D''(3, 0)

Answer:

A''(3/2, -3)

Answer:

8x = 32

x = 4

y = 6

Step-by-step explanation:

2.5y + 3x = 27

5x – 2.5y = 5

_____________

8x = 32 (equation obtained after adding the two equations)

x = 32/8

x = 4

Plug x = 4 in 2.5y + 3x = 27

2.5y + 3*4 = 27

2.5y + 12 = 27

2.5y = 27 - 12

2.y5= 15

y = 15/2.5

y = 6

The equation results of adding the two equations is 8x = 32.

The solution to the system is (4, 6).

A straight line on the coordinate plane is represented by a linear function. As an illustration, the equation y = 3x – 2 depicts a linear function because it is a straight line in the coordinate plane.

Any function whose graph is not a straight line is said to be nonlinear. Any curve other than a straight line can be a graph of it.

An example of a non-linear function is a quadratic function.

Given, A system of linear equations in variables 'x' and 'y'.

2.5y + 3x = 27...(i) and 5x - 2.5y = 5...(ii)'

Reaaranging eqn(i) we have

3x + 2.5y = 27...(iii)

Adding (ii) and (ii) we have,

8x = 32.       (As + 2.5y and - 2.5y cancels)

x = 32/8.

x = 4.

Putting the value of 'x' in eqn(i) we have,

2.5y + 12 = 27.

2.5y = 15.

y = 6.

So, The solution to the system is (4, 6).

Answer:

They started shopping for cloths at 11:45 AM

Step-by-step explanation:

First of all we have to calculate the whole time that they spent in the mall starting from shopping.

They spent 1 hour on shopping, 1 hour and 30 minutes at food court and 30 minutes in video arcade which makes:

[tex]1 + 1.5+ 0.5 = 3\ hours[/tex]

as 30 minutes is equal to half hour so we used 0.5 in place of it.

Now we know that they left at 02:45 PM. We have to see what time it was 3 hours ago.

[tex]02:45\ PM - 03:00 = 11:45\ AM[/tex]

Hence,

Step-by-step explanation:

add 4 on both sides

you then divide by negative 2

since you divide by a negative you have to switch the sign

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

17.5 Km

Step-by-step explanation:

In Monstor zip line, it's 120 km /hour

so in 0.25 hours, it's 0.25 * 120 = 30 Km

in another small

d = 50*h

= 50*0.25

= 12.5 km

so you travel (30-12.5)km farther on the monster zip line = 17.5 Km

Answer:

y= -8x-2

Step-by-step explanation:

30=32-2

B= -2

Answer: -8x^4+28x^3-28x^2+8x

Answer:

y=3/2x+3

Step-by-step explanation:

The equation is in y=mx+b format. m is the slope, or steepness of the line, while b is the y intercept (where the line crosses with the y axis).

The given line shows the y intercept; it's 3.

To find the slope, use this equation: y2-y1/x2-x1

Pick any two points and plug them into the equation. For example, use (0,3) (y intercept) and (-2, 0) (x intercept.)

now,

3-0/0-(-2)

3/2

the slope is 3/2.

Now, the line is

y=3/2x+3.

Step-by-step explanation:

This is a hopeless question. The best anyone can do is guess.

The only one that is completely wrong is C. It says that the more you watch TV the less snacks you eat. Not what the premise says.

D oddly enough could be. You might reach a pinacle and not want anything more. I don't think it is the intended answer, but it is possible.

B is hard to eliminate as well. There might not be any relationship at all or a very weak one. I think it should be eliminated because it most resembles C.

Step-by-step explanation:

i just did it on edg

The value of each coin (Nickels and Quarters) determines their number in a money sum

The correct option that gives the equation that can be used to solve for the number of nickels, n, is option;

0.05·n + 0.25·(36 - n) = 6

Reason:

The given equation can be presented as follows;

[tex]\begin{array}{|c|c|c|c|}&\mathbf{Number}&\mathbf{Value}&\mathbf{Total \ value}\\&&&\\Nickels&n&0.05&0.05 \cdot n\\Quarters&36 - n&0.25 & 0.25 \cdot(36 - n)\\&&&\\\mathbf{Total}&36&&6\end{array}\right][/tex]

From the above table, we have;

0.05·n + 0.25·(36 - n) = 6

Solving the above equation gives;

0.05·n + 9 - 0.25·n = 6

-0.2·n = 6 - 9 = -3

[tex]n = \dfrac{3}{0.2} = 15[/tex]

Therefore;

The equation that can be used to solve for the number of nickels, n, is; 0.05·n + 0.25·(36 - n) = 6

Answer:

Step-by-step explanation:

this equation is equivalent to y = -28, which is horizontal so it has a slope of 0

The domain and range of the function f(x)=28 is Domain: All real numbers Range: {-28}. The correct option is D.

The given function f(x)=-28 has a domain of all real numbers because the function can take any value of x. But, the range of the function is only -28. This is because for any input(x) the value of the function will remain the same which is equal to -28.

Hence, the domain and range of the function f(x)=28 is Domain: All real numbers Range: {-28}.
