Answer:
So in the past month Rita earned $18.50
Step-by-step explanation:
2.50 x 6 = 15
3.50 x 1 = 3.50
Answer:
a. D'(p) = -10p - 6
b. There is a decrease of 96 units of demand for each dollar increase
Step-by-step explanation:
The demand function is:
(a) The derivate of the demand function with respect to price gives us the rate of change of demand:
(b) When p = $9, the rate of change of demand is:
This means that, when p = $9, there is a decrease of 96 units of demand for each dollar increase.
Answer:
6x10⁹
Step-by-step explanation:
so we regroup them
(2×3)×(10⁵×10⁴)
6×10⁵+⁴
=6×10⁹
Answer:
x= 95/2 or x=47.5 or 47 1/2
Step-by-step explanation:
3x + 10 = 5(x - 17)
First Step:
multiply and combine the right side (parentheses)
5 times x = 5x 5 times -17 = -85
3x + 10 = 5x -85
Second Step:
Add like terms ----> which is: 3x and 5x -----10 and -85
BUT since you only want one x on one side, you combine x first.
3x + 10 = 5x -85
-5x -5x
-2x + 10 = -85
NOW
Third Step: Add the integers---> 10 and -85
you want to get 10 on the same side as the -85, so you subtract it from BOTH sides.
which brings you:
-2x + 10 = -85
-10 -10
<u> </u>
NOW that we've subtracted -10 from -85 it's technically just adding 85 and 10 then putting a negative sign on it.
so now we have:
-2x = -95
Step Four:
divide -2 from each side to get X alone
<u>-2x</u> = <u>-95</u>
-2 -2
ANSWER:
x=47.5
X-4y=7 Answer:1/4
2x+y=5
2x+y=5 I am not sure but I’m pretty sure the answer is -2
