Answer:
We know that the multiplicative rate of change of a function is the number by which each next term of an exponential function is increasing or decreasing. We can find multiplicative rate of change by dividing any term of the function by its previous term.
We are given here the individual costs of DVD and CD as well as the total sales and the number of items sold on one day. To solve the number of DVDs and CDs sold each, we devise two independent linear equations:
(1) x + y = 39
(2) 4x + 7y = 204
x- number of DVDs; y - number of CDs
solving, x= 23 DVDs
y = 16 CDs
Answer:
Yes
Step-by-step explanation:
To determine if (1, 2 ) is a solution of the inequality, substitute the coordinates into the inequality and if satisfied then they are a solution, that is
(6 × 1) - 2 = 6 - 2 = 4 > 3
Since 4 > 3 then (1, 2 ) is a solution
Hello from MrBillDoesMath!
Answer:
m = 11/12
Discussion:
Slope of line = m = (change in y) / (change in x)
= ( 11 - 0) / (17-5)
= 11/12
Thank you,

Answer:
<h2><u><em>
A 4 + 12+2 = 18</em></u></h2>
Step-by-step explanation:
which expression is equivalent to 4+ [4 x (5-2)] + 2?
A 4 + 12+2
B 4 + 18 + 2
C 8x3 + 2
D 8 x 5 - 1
4+ [4 x (5-2)] + 2 = 18
A 4 + 12+2 = 18
B 4 + 18 + 2 = 24
C 8x3 + 2 = 26
D 8 x 5 - 1 = 39
check
4 + [4 x (5-2)]+ 2 = 4 + 12 + 2
18 = 18
the answer is good
