Answer:

(C) Infinitely many solutions

Step-by-step explanation:

Converting the lines into the from [tex]ax+by+c=0[/tex]

[tex]5y=15x-40\\\Rightarrow 15x-5y-40=0[/tex]

[tex]y=3x-8\\\Rightarrow 3x-y-8=0[/tex]

[tex]\dfrac{a_1}{a_2}=\dfrac{15}{3}=5[/tex]

[tex]\dfrac{b_1}{b_2}=\dfrac{-5}{-1}=5[/tex]

[tex]\dfrac{c_1}{c_2}=\dfrac{-40}{-8}=5[/tex]

So, [tex]\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}=\dfrac{c_1}{c_2}[/tex].

Hence, these lines have infinitely many solutions.

Complete Question:

There are 10 marbles. What is the probability of drawing 2 blue marbles if the first marble is NOT placed back in the bag before the second draw.

2 yellow, 3 pink, 5 blue    

Answer:

[tex]P(B_1\ and\ B_2) = \frac{2}{9}[/tex]

Step-by-step explanation:

Given

[tex]Blue = 5[/tex]

[tex]Pink = 3[/tex]

[tex]Yellow = 2[/tex]

[tex]Total = 10[/tex]

When the first blue marble is selected, the probability is:

[tex]P(B_1) = \frac{n(Blue)}{Total}[/tex]

[tex]P(B_1) = \frac{5}{10}[/tex]

Since the first marble is not returned, we have the following marbles left

[tex]Blue = 4[/tex]

[tex]Pink = 3[/tex]

[tex]Yellow = 2[/tex]

[tex]Total = 9[/tex]

The probability of picking a second blue marble is:

[tex]P(B_2) = \frac{n(Blue)}{Total}[/tex]

[tex]P(B_1) = \frac{4}{9}[/tex]

So, the required probability is:

[tex]P(B_1\ and\ B_2) = P(B_1) * P(B_2)[/tex]

[tex]P(B_1\ and\ B_2) = \frac{5}{10} * \frac{4}{9}[/tex]

[tex]P(B_1\ and\ B_2) = \frac{5*4}{10*9}[/tex]

[tex]P(B_1\ and\ B_2) = \frac{20}{90}[/tex]

[tex]P(B_1\ and\ B_2) = \frac{2}{9}[/tex]

Explanation:

A regular polygon must have all sides of equal length. Also, all angles must be the same measure. This applies to the equilateral triangle in the upper left corner, and the square in the upper right corner. Each angle of the square is 90 degrees even though your teacher didn't use right angle markers.

The middle figure in the top row is not a regular polygon because the sides are not all the same length. Also, the angles are different.

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

In the bottom row, only the first figure is a regular polygon for similar reasons mentioned earlier. The second figure is not a regular polygon because this figure is concave. Only convex polygons can be regular.

The third figure in the bottom row is not regular because one side is longer than the others.

Graph (C) represents y = x.

Graph (E) represents x = 3.

Graph (D) represents x + y = 3.

The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.

These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.

The graph of the function y = x is a straight line with equal values of x and y coordinates.

So, Graph (C) represents y = x.

The graph of x = 3 will be a straight line parallel to the y-axis at x equal to 3 so, Graph (E) represents x = 3.

The graph of x + y = 3 has y = 3, when x = 0 and x = 3 when y = 0, having coordinates (0, 3) and (3, 0) so, Graph (D) represents x + y = 3.

Answer:

1  3/4

Step-by-step explanation:

Answer:

7/4

Step-by-step explanation:

We have the equation 2 - 1/4. The question is asking us to solve and turn the answer into a fraction.

So let's solve it first.

To make this easier, we must turn 1/4 into a decimal, which would be 0.25.

2 - 0.25

1.75

Now that we have the answer, we must change it into a fraction, so :

1.75 = 7/4

Therefore, 7/4 is the answer.

Answer: B, D, and maybe E. Check my explanation for 'E'

Step-by-step explanation:

There are a few ways of visualizing the expression, but Ill try to show it to easiest way possible.

[tex]x^\frac{3}{2} =(x^3)^\frac{1}{2}[/tex]

Notice nothing was changed because of the property of exponents. An exponent to a power means to multiply them. A thing you should remember for all future cases is that the one-half power means square root. It is the exact same thing. Therefore the new expression I created is the square root of 'x' cubed.

A:) This would be equivalent to x^2/3

B:) This is equivalent to x^3/2 because the square root is the 1/2 power to the power of 3.

C:) This would be equivalent to x^2/3

D:) This is equivalent to x^3/2 because the square root is the 1/2 power, but multiplied by the power under the radical.

E:) If this answer is to the third power, then it is equivalent. I cannot tell from this picture.

Answer: Slope of line = [tex]\frac{1.2}{2}[/tex]

Graph- see picture.

Step-by-step explanation:

Graphs are graphed using y=mx+b

Slope (m) is written as [tex]\frac{rise}{run}[/tex], and y coordinate is up and down, x is left & right.

The y coordinate adds 1.2 every time, so the rise is 1.2.

The x coordinate adds 2 every time, so the run is 2.

The y intercept (b) simply means where the line intercepts the y axis.

It is given that the y intercept is 0.

So, the graphing equation: y= [tex]\frac{1.2}{2}[/tex]x

We don't need to put the y intercept because it is 0!

The graph is attached!

Answer:

x/121 + y/9 = 1

Step-by-step explanation:

The major axis is 22 units long, in a horizontal line, and the center is in the middle of the major axis line segment. The center is at the origin. The distance of the whole axis is 22, and its endpoints are 11 units from the center. The axis length is 2a = 22, so a = 11.

Becasue the major axis is horizontal, this ellipse is wider than it is tall.

The minor axis is perpendicular to the major axis and it always shoter (hence the name 'minor'). In this case, it is vertical, is 6 units long, so we say that 6 = 2b, and b = 3.

The ellipse center is (h,k). But in this case, the center is the origin, so h = 0 and k = 0.

The equation for a horizontal ellipse is (x-h)²/a² + (y-k)²/b² = 1, a>b

(x-0)²/11² + (y-0)²/3² = 1

*** x/121 + y/9 = 1

The equation for a vertical ellipse is (x-h)²/b² + (y-k)²/a² = 1, a>b

If the bigger denominator is under 'x' term the ellipse is horizontal, with the longer axis being horizontal.

If the bigger denominator is under the 'y' term, the ellipse is vertical, with the longer axis being vertical.

The 'brainly ellipse' is form this particular problem.

Answer:

x = -17

y = -68

Step-by-step explanation:

x - y = 51

y/x = 4  so we can say that y = 4x

using substitution:

x - 4x = 51

-3x = 51

x = -17

find 'y':

-17 - y = 51

-y = 68

y = -68

check:

-17 - (-68) = 51

51 = 51

-68/-17 = 4

4 = 4
