<h3>
Answer: Choice C) $1,444.50</h3>
========================================================
There are two methods to get the answer.
The slightly longer method is to take 7% of the original price to get
7% of 1350 = (7/100)*1350 = 0.07*1350 = 94.50
The sales tax is $94.50
Add this onto the original price to get 1,350+94.50 = 1,444.50
----------------------------
A shortcut is to multiply the original price by 1.07
The multiplier 1.07 represents a 7% increase since
- 1 = 100%
- 0.07 = 7%
- 1.07 = 1 + 0.7 = 100% + 7%
So we will have 1.07*1350 = 1,444.50
Answer:
-2
Step-by-step explanation:
Answer:
F(-1) = 1
x = 3
Step-by-step explanation:
1) Assume that f(-1) = y1
So that point A (x1 = -1; y1) is a point lying in the graph representing the equation y = f(x)
As it can be seen in the figure, the graph representing that equation crosses point (-1; 1)
=> Point A has y1 = 1
=> f (-1) =1
2) Assume that f(x2) = -2
So that point B (x2; y2 = -2) is a point on the graphy representing the equation y = f(x)
As indicated in the figure, the graph crosses point (3; -2)
=> Point B has x2 = 3
=> When f(x) = -2, x = 3
Answer:
You can also work on the ways that you write polynomials. One way to write a polynomial is in standard form. In order to write any polynomial in standard form, you look at the degree of each term. You then write each term in order of degree, from highest to lowest, left to right.
Step-by-step explanation:
Write the expression 3x−8+4x5 in standard form.
First, look at the degrees for each term in the expression.
3x has a degree of 1
8 has a degree of 0
4x5 has a degree of 5
Next, write this trinomial in order by degree, highest to lowest
4x5+3x−8
The answer is 4x5+3x−8.
The degree of a polynomial is the same as the degree of the highest term, so this expression is called a fifth degree trinomial.
The price of album y is $5.80. I solved the system of equations of B and C. Getting rid of the variable z, I was able to get rid of x next. Solving this system gave me $5.80 without having to substitute into the other equation.
