Answer:

= 18 red marbles

Step-by-step explanation:

Let x be the number of red marbles that must be added

Therefore;

New number or red marbles = x+12

Total marbles will be x+32

Thus;

The probability of selecting a red marble = (x+12)/(x+32)

Therefore;

(x+12)/(x+32)=3/5

5(x+12)=3(x+32)

5x+60+3x+96

2x=36

x=18

Equation M: y = 3x + 4
solmaris [256]
Y = 3x + 4
y = 3x + 7

3x + 4 = 3x + 7
3x - 3x = 7 - 4
0 = 3.....incorrect....this system has no solutions because ur lines are parallel and they never cross.

or look at it this way..
y = 3x + 4
y = 3x + 7

both have slopes of 3...but the y intercepts are different......when this happens, it means the lines are parallel with no solution

The answer is 2

From the function when the input is 2 the output is -7. The inverse reverses the order so the input will be -7 and the output will be 2.

The slope formula can be used to find the slope, m, of a line with points (L1, y1) and (22, 42).
Helga [31]

Answer: (y-y_1)=m(x-x_1)\ or \ (y-y_2)=m(y-y_2)

Step-by-step explanation:

Point slope form: (y-b)=n(x-a) , where n=slope , (a,b) is the point through which line passes.

If slope of the line = m and line passes through (x_1,y_1) and (x_2,y_2) :-

(y-y_1)=m(x-x_1)\ or \ (y-y_2)=m(y-y_2)

So, the equivalent equations are :

(y-y_1)=m(x-x_1)\ or \ (y-y_2)=m(y-y_2)
