Answer:
X = 5
Step-by-step explanation:
I think there a problem with the question, If there is one less person in the group then the payment by each remaining person is must more than $2 than the previous, because the rent cost unchanged but the number of people in the group decreased.
Before, cost per person :
After cost per person: =
However, the payment by each remaining person is more than $2 than the previous, so
=
+ 2
<=>
- 2x -40 = 0
<=> X = 5
Answer: 2/5 chance
Step-by-step explanation: Since there are 5 marbles and 3 aren't yellow, you have a 2/5 chance to choose the other two yellow marbles
Answer:
x = -1, x = 1
Step-by-step explanation:
These are both vertical lines, meaning they are both parallel with the y-axis. Since they are both parallel to the y-axis, this means they're parallel to each other. Parallel lines never intersect.
Answer:
The answer is below
Step-by-step explanation:
A linear equation is represented by the equation y = mx + b, where m is the rate of change, b is the value of y at x = 0, y is a dependent variable and x is an independent variable.
a) Given that number of chirps per minute, C is dependent on the temperature, T, when T = 45 degrees, C = 0, this can be represented as (45, 0).
Also at 75 degrees, C = 126 it can be represented as (75, 126).
Using (45, 0) and (75, 126), we can determine the equation of the line from:
b) At t = 90°:
C = 4.2(90) - 189
C = 189 chirps per min
