Question:

Use PEMDAS to solve the following equation: 5 x (3 + 5) - 6 + 2 x 3

Niky A.

Answer:

The first step in PEMDAS is to address the parentheses: =5 x (8) - 6 - 2 x 3 Because there is no exponents, we do multiplication next =40 - 6 - 6 There is no division or addition so next comes subtraction =28 Our answer is 28

Question:

Find the slope of the line: 5x + 3y = 12

Niky A.

Answer:

The first steps is to solve for y: 5x+3y-(5x) = 12-(5x) 3y = 12 - 5x 3y/3 = 12/3 - 5x/3 y = 4 - (5/3)x This equation is now in slope intercept form (i.e. y = mx + b, where m is the slope and b is the y-intercept) So if we rearrange the equation: y = -(5/3)x + 4 From this rearrangement, we get that mx = -(5/3)x so the slope is -(5/3).
