Ok so function means that x never repeats with a different y
function could be
table: (1,2) (2,4) (4,8) etc
graph the points
not a function could be
(1,1) (2,1) (3,1) (4,1)
range is the output or y
range is R={-4,-1,2,5}
Step-by-step explanation:
4 + n + 7m
constants are just the numbers with no variables (letters)
so the constant is 4
coefficients are numbers multiplied by variables (letters)
so the coefficients are : 7 and 1
the error sarah made is forgetting the coefficient of n......because even if it is not written, n is the same as 1n....so basically, there is a coefficient for EVERY variable, even if its not written.
Answer:
56 mins
Step-by-step explanation:
Number of gallons of water in the pool per minute;
750 divided by 35 = 150/7
Let the time needed to fill a 1,200 gallon pool be t.
t x 150/7 = 1,200
t x 21.42857142857143... = 1,200
t = 1,200/21.42857142857143
t = 56 mins
Step-by-step explanation:
8) 52
9) (135/2) or 67.5
10)(32/5) or 6.4
30 feet by 14 feet just means 30x14 which is equal to 420 square feet if each piece is 1x1 then he will need 420 pieces of sod
