How can I create a function where the domain would be: All real numbers, whole number and be greater than or equal to 10 x less than or equal to 40

Leo has b boxes of pencils. each box contains 6 pencils. he has a total of 42 pencils. the equation that represents this situation the value of b that makes the equation true the first one is b+6=42,6b=42,b=42+6,or 42b=6 the second one are 7,836 48

Identify the slope an intercept of the following linear equation y = 1/5x - 6 a. slope: 1/5; intercept: -6 b. slope: 5; intercept: -6 c. slope: -1/5; intercept: 6 d. slope: 1/5; intercept: 6

Solve the equation: x - 9 = -6 + 5 a. 21 b. 7 c. 14 d. 2
