System of equations, special case infinitely many solutions?????

Mashcka [7]

One possible system is

1x + 3y = 4

2x + 6y = 8

Note how 2 is twice as large as 1, 6 is twice as large as 3, and 8 is twice as large as 4.

In other words, the second equation is the result of multiplying both sides of the first equation by 2.

1x+3y = 4

2*(1x+3y) = 2*4

2x+6y = 8

Effectively the two equations in bold are the same which produces the same line. The two lines overlap perfectly to intersect infinitely many times. An intersection is a solution.

In an experiment, a ball is drawn from an urn containing 12 purple balls and 13 green balls. If the ball is purple, two coins ar

UNO [17]

Answer:

4 elements of the sample space will have a purple ball

There are 10 elements altogether

Step-by-step explanation:

Probability is given by number of possible outcomes ÷ number of total outcomes

Number of purple balls = 12, number of green balls = 13, total number of balls = 12+13 = 25

Probability (a ball drawn is purple) = 12/25

If a purple ball is drawn, two coins are tossed

1 coin has 2 elements

2 coins have 2×2 = 4 elements

Probability (a ball drawn is not purple) = 1 - 12/25 = (25-12)/25 = 13/25

If a ball drawn is not purple, three coins are tossed

1 coin has 2 elements

3 coins have 3×2 = 6 elements

Total elements = 4 + 6= 10 elements

Please help me on my math

s344n2d4d5 [400]

Answer:

m = -8

b = -24

Step-by-step explanation:

To solve this problem use the hint and put this equation in y = mx + b form. This is called slope-intercept form.

In slope-intercept form, the coefficient of x (which is m) is the slope of the line and b is the y-intercept of the line.

-32x - 4y = 96

Add 32x to both sides of the equation.

-4y = 32x + 96

Divide both sides of the equation by -4.

y = -8x - 24

Comparing this to y = mx + b, the -8 is "m" and -24 is "b". Therefore your final answers are:

m = -8

b = -24
