Number of questions worth 5 points = 10
Number of questions worth 2 points = 25
Further explanation:
The given system is a system of linear equations in two variables.
We will use the subsitution method to solve the system
Given equations are:
From equation no 1:
Putting x=35-y in second equation
Hence,
Number of questions worth 5 points = 10
Number of questions worth 2 points = 25

Answer:
k = -2
Step-by-step explanation:
The determinant can be formed by subtracting up-diagonal products from down-diagonal products:
(x)(x+y)(y) +(y)(x)(x+y) +(x+y)(y)(x) -(x+y)^3 -x^3 -y^3
= 3xy(x+y) -(x^3 +3x^2y +3xy^2 +y^3) -x^3 -y^3
= -2(x^3 +y^3)
The value of k is -2.
<h3>Answer:</h3>
A) x = 2
<h3>Explanation:</h3>
<em>Try the answers</em>
Of the offered choices, the only ones that go through the given point are ...
... x = 2
... y = -5
The latter is horizontal and parallel to y = 7, so is not the choice you want. The appropriate choice is ...
... A) x = 2
_____
<em>Figure out the answer</em>
The given line is horizontal, so the line you want is vertical—of the form ...
... x = constant
The constant must be chosen so the line will go through a point with x=2. It should be obvious that the constant must be 2.
... x = 2 is perpendicular to y = 7 and goes through (2, -5).

Not directly. But the quadratic formula can do it. But that's not your question.
the factors you get must contain the factors for 1 which are 1 and - 1
These factors must add to - 5. There's no way that will happen with 1 and - 1 and you would be creative math if you tried to say that you could make one of the factors (x -1-1-1-1-1-1). That creates a whole new question.
