Answer:

m = -2

Step-by-step explanation:

This equation is in point-slope form

The numbers added or subtracted by a variable are a coordinate point.

y + 2 --> (0,-2)

x - 3 --> (3,0)

(3,-2)

The slope is represented by the number outside of the parentheses.

Therefore, the slope of the line is -2

Answer:

-2

Step-by-step explanation:

This equation is written in point slope form

y-y1 = m(x-x1)

where (x1,y1) is a point on the line and m is the slope

y- -2 = -2(x -3)

A point on the line is (-3, -2) and the slope is -2

Calculating the Least Common Multiple

9.1 Find the Least Common Multiple

The left denominator is : 50

The right denominator is : 25

Number of times each prime factor

appears in the factorization of:

Factor Left

Denominator Right

Denominator L.C.M = Max

{Left,Right}

Prime Factors 50 25 50

Least Common Multiple:

50

Calculating Multipliers :

9.2 Calculate multipliers for the two fractions

Denote the Least Common Multiple by L.C.M

Denote the Left Multiplier by Left_M

Denote the Right Multiplier by Right_M

Denote the Left Deniminator by L_Deno

Denote the Right Multiplier by R_Deno

Left_M = L.C.M / L_Deno = 1

Right_M = L.C.M / R_Deno = 2

Making Equivalent Fractions :

9.3 Rewrite the two fractions into equivalent fractions

Two fractions are called equivalent if they have the same numeric value.

For example : 1/2 and 2/4 are equivalent, y/(y+1)2 and (y2+y)/(y+1)3 are equivalent as well.

To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.

L. Mult. • L. Num. 837

—————————————————— = ———

L.C.M 50

R. Mult. • R. Num. 279 • 2

—————————————————— = ———————

L.C.M 50

Adding fractions that have a common denominator :

9.4 Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

837 - (279 • 2) 279

——————————————— = ———

A cooler contains 7 cans of soda; 3 colas, 3 orange, and 1 cherry. Two cans are selected at random without replacement. Find

erastovalidia [21]

P(NOT Orange)=(4/7)(3/6)

P(NOT Organge)=2/7

P(O>0)=1-2/7

P(O>0)=5/7

So the probability of at least one orange can is 5/7
