Write an equation for this: Forty-five more than 0.3 times a number is the same as 33 less than the product of -7.5 and the number.

45 + 3 x n = -7.5 x n - 33

Step-by-step explanation:

(The x means times, NOT a variable)

(The n is the number that we don't know of, the variable)

Hope this helps!!

step-by-step explanation:

b and c

step-by-step explanation:

total income = price of one ticket   *   number of tickets sold

  y                 =     4                                   x

so the equation is y=4x     with x≥0   because number of tickets sold can not be negative

thus the equation is a semi -line with an end point at

(0,0)

passing through :

x=1     y=4(1) = 4   so through (1,4)
