Answer:
First one: 5x3(0.75)2t
and fourth one: 0.05x500(0.005)t
Step-by-step explanation:
In order to have an exponencial decay, the rate of the exponencial function needs to be lesser than 1.
The rate is the value between parenthesis, so in the first equation, the rate is 0.75, so this is an exponencial decay.
The second equation has rate = 2.4, so this is not an exponencial decay.
The third equation has rate = 1.04, so this is not an exponencial decay.
The fourth equation has rate = 0.005, so this is an exponencial decay.
Answer:
Hi there!
Your answer is:
7, 8, 9, 10
Step-by-step explanation:
to determine this:
x, x+1, x+2, x+3 = 34
x+ x+1 +x+2 + x+3 = 34
Combine like terms!
4x +6 = 34
-6
4x = 28
/4
x = 7
SO:
plug 7 into your equation to determine integers!
7, (7+1), (7+2), (7+3)
7, 8 , 9, 10
I hope this helps!
Answer:
Option B.
The price of a senior citizen ticket is $11 and the price of a child ticket. is $7
Step-by-step explanation:
Let
x ----> the price of a senior citizen ticket
y ---> the price of a child ticket.
we know that
First day
-----> equation A
Second day
----> equation B
Solve the system by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
The solution is the point (11,7)
therefore
The price of a senior citizen ticket is $11 and the price of a child ticket. is $7
Hey there! :)
Answer:
y -3 = -2(x + 4).
Step-by-step explanation:
Begin by calculating the slope of the line shown in the graph. Use the slope formula:
Plug in two coordinates:
Simplify:
Therefore, the slope of the line is 1/2.
A line that is perpendicular contains a slope that is the negative reciprocal. Therefore:
1/2 --> -2.
Plug the slope into the point-slope formula:
y -3 = -2(x + 4). This is your equation in point-slope form!
Answer:
They are equal. x= -24
Step-by-step explanation:
-2x - 7 ≥ 41
First you isolate the variable
-2x -7 ≥ 41
+7 +7
-2x≥48
then divide each side by -2
x≥-24
Then go back and plug in
-2(-24)-7=
48-7=41
Therefore
41=41
