Answer:
Do you have answer choices
Step-by-step explanation:
Answer: the system of equations are
x + y = 35
3x + 2y = 100
Step-by-step explanation:
Let x= the number of short answer questions.
Let y= the number of multiple choice questions.
Noah wants 35 questions on the exam. This means that
x + y = 35
He plans to mix short answer questions, worth 3 points, with multiple choice questions worth 2 points. This means that x short answer questions will give 3x points and y multiple choice questions will give 2y points
Since the exam is worth 100 points, then,
3x + 2y = 100 - - - - - - - -1
Substituting x = 35 - y into equation 1, it becomes
3(35 - y) + 2y = 100
105 - 3y + 2y = 100
y = 105 - 100 = 5
x = 35 - y = 35 - 5
x = 30
Answer:
Option a. $2,040
Step-by-step explanation:
step 1
To find out the amount of the additional passive income last year, subtract the amount earned at her salaried job from Loretta’s income last year
so
step 2
Divide the additional passive income last year by 12 (number of months in a year)
therefore
approximately $2,400 per month
Answer:
The <em>x</em>-intercept would be at the point where there are 0 downloads in <em>x</em> days.
Step-by-step explanation:
The <em>x</em>-intercept of a function is the point where the graph of the function crosses the <em>x-</em>axis and the <em>y</em>-coordinate is 0.
That is, the point (<em>x</em>, 0) is the <em>x</em>-intercept of a function.
In this case the data provided is for the number of free downloads using the promo code (f (x), in tens of thousands) and the time since posting (<em>x</em> days).
So, in this case the <em>x</em>-intercept would be at the point where there are 0 downloads in <em>x</em> days.
I'm assuming that by "opposite of 12", it means -12
If so, the answer would be 2
