Answer:
You didn't really word your question right, you missed some words
Step-by-step explanation:
Assuming that both triangles are an exact copy of one another, it is safe to assume that 3y-7 is equal to 41. Set up an equation
3y-7=41
Add 7 to both sides
3y=48
Divide both sides by 3
y=16
Now to find PN.
Based on what we know, we can assume that MP = PN. Let's make some equations!
MP = 17x-8 PN = 11x+4
17x-8 = 11x+4
Subtract 11x from both sides
6x-8 = 4
Add 8 to both sides
6x = 12
Divide by 2
x=2
Substitute 2 in for x in the equation for PN
11(2)+4
Multiply 11 by 2
22+4 = 26
PN = 26
I am assuming the problem is asking you to find an equation repersenting the situation.
In this case, realize that 150 will be a constant, and 60 will be attached to the
variable, since the price of the textbooks changes based on how many textbooks there are.
Thus, the equation is:

Our answer is 60x + 150 = y.
Answer:
<em>The zeros of the polynomial are -1 and 5</em>
Step-by-step explanation:
<u>Quadratic Equation Solving</u>
The standard representation of a quadratic equation is:

where a,b, and c are constants.
Solving with the quadratic formula:

We have the following equation to solve:

Before attempting to solve it, we must simplify the equation.
Collecting like terms and reordering:

Here: a=1, b=-4, c=-5
The discriminant of this quadratic equation is:


Given d is positive, the equation has two roots, and since d is a perfect square, both roots are rational.
Applying the formula:


Dividing by 2:

Separating both roots:
x = 2 + 3 = 5
x = 2 - 3 = -1
The zeros of the polynomial are -1 and 5
