Answer:
15 two-point questions and 5 four-point questions.
Step-by-step explanation:
Let x represent number of two-points questions and y represent number of four-points questions.
We have been given that Janice wants to create a test containing 20 questions. We can represent this information in an equation as:

Since all questions are worth 50 points. We can represent this information in an equation as:

From equation (1), we will get:

Upon substituting this value in equation (2), we will get:







Therefore, there are 5 questions that are worth 4 points each.
Now, we will substitute
in equation (1) to solve for x.



Therefore, there are 15 questions that are worth 2 points each.
The slope of diagonal <em>AB</em> is 0 and its equation is y=2.
Answer:
See below for answers
Step-by-step explanation:
1) Parent functions are essentially non-transformed functions, so y=x^2 would be the parent function of y=x^2+1 for example since y=x^2 has no transformations while y=x^2+1 does.
2) Since certain x-values won't be defined for the function, you need to restrict the domain. For example, in the function f(x)=1/x, obviously x=0 is undefined for the function, so we would need to restrict the domain.
3) Not sure what you mean by name graph; no context given
4) Also no context given
5) The equation would be y=(x+5)^4-3
The perimeter of the square is:
ft
Step-by-step explanation:
The picture is attached with the answer.
the diagonal of a square divides it into two right angled-triangles.
We can use one of the triangle to find the length of side as the diagonal will be the hypotenuse of the triangle
Let a be the side of the square, then according to Pythagoras theorem

Dividing both sides by 2

Taking Square root on both sides

Now,

Hence,
The perimeter of the square is:
ft
