5(6+9)
Times the five by the numbers in the bracket
30 + 45
=75
The given table is
c 1 2 3 4 5
f 6 6 7 8 8
c = the number of children
f = the fee per hour
The given information is
f = $6 when c = 2;
f = $7 when c = 3;
f = $8 when c = 4 or c = 5.
A graph of the data is shown below.
Notice that the fee for 1 child was not provided, but it was provided in the table.
Let us examine the given answers.
(a) The relationship is not linear between c and f.
TRUE
(b) The relationship is linear between c and f.
FALSE
(c) The relationship is not linear for and linear for f.
FALSE
(d) The relationship is linear for c but not f.
FALSE
Answer: The relationship is not linear between c and f.
Step-by-step explanation:
Any lines that are parallel to each other have the same slope (coefficient of x is the same)
In this case, y = 2x + c.
Since it includes the point (0, 1), the y-intercept is 1 and that is c itself.
Hence, the equation of the parallel line is y = 2x + 1.
Answer:
-9x^2 - 15x.
-3x.
Step-by-step explanation:
The first quotient is -9x^2 - 15x.
To find the second result we divide the above by 3x + 5:
-3x
____________
3x + 5) -9x^2 - 15x
-9x^2 - 15x
-----------------
..................
The result is -3x.
