Answer:

y=x+8 because your friend's allowance is y but also $8 more than yours, x. x+8 is her allowance so x+8=y

Answer:

x^2+4y^2-8x+8y+4=0

Step-by-step explanation:

The general form of the given ellipse is x² +4y² - 8x + 8y + 4 = 0.

An ellipse can be defined as a shape that looks like an oval circle.

The equation of an ellipse is

[tex]\dfrac{\left(x - h\right)^{2}}{a^{2}} + \dfrac{\left(y - k\right)^{2}}{b^{2}} = 1[/tex]

Where (h, k) is the center a and b are the lengths of the semi-major and the semi-minor axes.

The vertices of an ellipse are (0,-1) and (8,-1).

The endpoints of the minor axis are (4,1) and (4,-3).

The following equations take into account the different properties of an ellipse:

[tex]k = -1k=−1, h^{2} = a^{2}h 2 =a 2 , \left(h - 8\right)^{2} = a^{2}[/tex]

[tex]\begin{cases} b = 2 \\ k = -1 \\ h^{2} = a^{2} \\ \left(h - 8\right)^{2} = a^{2} \end{cases}[/tex]

We get that h = 4 k = -1, a = 4, and  b = 2

The standard form of the given ellipse is

[tex]\dfrac{\left(x - 4\right)^{2}}{4^{2}} + \dfrac{\left(y + 1\right)^{2}}{2^{2}} = 1[/tex]

So the general form will be as : x² +4y² - 8x + 8y + 4 = 0.

Thus, the general form of the given ellipse is x² +4y² - 8x + 8y + 4 = 0.

Answer:

The right answer would be (D) x = 1.

Step-by-step explanation:

So since triangles ABC and DEC are congruent to each other, your gonna try to find the value of x. So from the figure we know that AB = 4x - 1, BC = 4, AC = 5,  DE = x+2, CE = 4 and EC = 5. And since ΔABC ≅ ΔDEC the corresponding sides would be equal. And after, we will have :

AB = DE

4x - 1 = x + 2

4x - x =2 + 1

3x = 3

x = 1

So, as it shows, the value of x is one. So (D) x = 1 is the right answer. Hope this helped! :)

Answer:

4/225

Step-by-step explanation:

To get 3 marbles that all three are different colors, we need to get a red, blue, and yellow marble (not necessarily in that order)

So we get the probability of getting each with replacement (meaning they are all out of 15) and multiply them.

The probability of getting a red is:

10/15 = 2/3

The probability of getting a blue is:

3/15 = 1/5

The probability of getting a yellow is:

2/15

So to get all 3 different colors:

2/3 * 1/5 * 2/15 = 4/225

Answer:

For the value of hypotenuse can be irrational, sum of squares of other two legs might be imperfect square number.

Step-by-step explanation:

We all know, the Pythagorean theorem can be stated as follows:

The sum of squares of two legs of a right angled triangle is equal to the square of the hypotenuse.

i.e.

[tex]a^2+b^2=c^2[/tex]

Where, [tex]c[/tex] is the hypotenuse and [tex]a, b[/tex] are the two other legs of the right angled triangle.

Given that:

[tex]a[/tex] and [tex]b[/tex] are rational numbers.

To find:

Situation for which [tex]c[/tex] is irrational.

Square of a rational number is always rational.

So, [tex]a^{2} , b^{2}[/tex] both will be rational.

And sum of squares of two rational numbers will also be rational.

Therefore, [tex]a^2+b^2[/tex] will also be rational.

and

[tex]c = \sqrt{a^2+b^2}[/tex]

For the value of [tex]c[/tex] can be irrational, sum of squares of other two legs might be imperfect square number.

Answer:

When x = 2, y = 6

Step-by-step explanation:

Constant of Proportionality:  y = kx      

   (24) = k(8)

     24 = 8k

       k = 3

     y = kx       ===>        y = 3x

When x = 2:

  y = 3x

  y = 3(2)

  y = 6

The two numbers of seven less than 4 times the square of a number is 18 are -5/2 and 5/2

Let the unknown number be "x"

If the resulting expression is 18, this will be expressed as 4x² - 7 = 18

Solving the resulting expression

[tex]4x^2-7=18\\4x^2= 18+7\\4x^2=25\\x^2=\frac{25}{4}\\x=\pm \frac{5}{2}[/tex]

Hence the two numbers of seven less than 4 times the square of a number is 18 are -5/2 and 5/2

Answer:

Expressions A, E, and F

Step-by-step explanation:

In general, when negative integers are multiplied; if the negative integers are even, then the product would be positive. But if the negative integers are odd, then the product would be negative.

Thus,

A. (−5)(−0.4)(1.8) = (2.0)(1.8)

                           = 3.6

B. (-45)(-19)(-112) = (855)(-112)

                           = -95760

C. −1(5+17) = -1(22)

                 = -22

D. (−5)(−0.4)(1.8)(−3.25) = (2.0)(-5.85)

                                      = -11.7

E. (-49)(-34)(-12)(-12) = (1666)(144)

                                = 239904

F. −1(3.5−7) = -1(-3.5)

                  = 3.5

Thus expressions A, E and F have positive products.
