Answer:
The system will be:
x - y = 12
3x + 5y = 100
Step-by-step explanation:
Let The number of three-point questions ⇒ x
And the number of five-point questions ⇒ y
The giving a test has 12 more three-point questions than five-point questions.
So, x - y = 12
The test is worth 100 points.
So, 3x + 5y = 100
So. the system which represents this information is:
x - y = 12
3x + 5y = 100
And the solution of the system is x = 20 and y = 8
The number of three-point questions ⇒ x = 20 questions.
The number of five-point questions ⇒ y = 8 questions.

Answer:
Step-by-step explanation:
Given
(0, 1, 0)
The vector equation is given as:
Substitute values for x, y and z
Differentiate:
The parametric value that corresponds to (0, 1, 0) is:
Substitute 0 for t in r'(t)
The tangent line passes through (0, 1, 0) and the tangent line is parallel to r'(0)
It should be noted that:
The equation of a line through position vector a and parallel to vector v is given as:
Such that:
and
The equation becomes:
By comparison:
and
The parametric equations for the tangent line are:
Answer:
weight of a basket of apples
Step-by-step explanation:
because a quantitative variable involves numbers, and the weight of a basket of apples would be a number. all of the other answers describe details of something, but wouldn't involve a specific number.
