A new novel is selling for $17.95. If it is on sale at 40% off, find the amount of discount and the sale price.
A. Discount: $10.77; Sale Price: $7.18
B. Discount: $4.39; Sale Price: $13.56
C. Discount: $13.56; Sale Price: $4.39
D. Discount: $7.18; Sale Price: $10.77
Answer:
A
Step-by-step explanation:
multiply $17.95 by 40% to get the discount ($17.95 x .4), which equals $7.18.
the sale price is the initial price of the book less the discount ($17.95-$7.18), which equals $10.77.

What is the order, from widest to narrowest graph, of the
quadratic functions f(x) = -0.5x2, f(x) = 1/4x2, and f(x) = x2?
Answer:
f(x) = [tex]\frac{1}{4}x^{2}[/tex] > f(x) = -0.5x² > f(x) = x²
Step-by-step explanation:
In a quadratic function leading coefficient decides the width of a graph.
In simpler words, leading coefficient decides the vertical stretch of the graph.
Higher the value of leading coefficient, higher the vertical stretch.
When a graph is vertically stretched it becomes narrower.
(Note: Minus sign of the coefficient decides the opening of the graph, upwards or downwards)
Therefore, f(x) = x² having coefficient = 1 is the narrowest and f(x) = [tex]\frac{1}{4}x^{2}[/tex] will be the widest.
So the descending order will be,
f(x) = [tex]\frac{1}{4}x^{2}[/tex] > f(x) = -0.5x² > f(x) = x²

Solve for the value of x in the picture above.
Answer: C
Step-by-step explanation:
The triangle in the picture is an equilateral triangle. We know this is true because all sides are equal, as denoted by the tick marks. In equilateral triangles, each angle is 60° because when you add all the angles, you get 180°.
4x+8=60 [subtract both sides by 8]
4x=52 [divide both sides by 4]
x=13
Now, we know that C is the correct answer.
What is the solution to the given inequality?
-2x + 4 < 12
Answer:
-4
Step-by-step explanation:
-2x +4 < 12
-2x < 12 -4
-2x < 8
x > -8/2
x > -4
Answer:
x > - 4
Step-by-step explanation:
- 2x + 4 < 12 ( subtract 4 from both sides )
- 2x < 8
Divide both sides by - 2, reversing the symbol as a result of dividing by a negative quantity.
x > - 4

You have a total of 10 coins consisting of nickels and dimes in your pocket. The value of the coins is $0.70. Write and solve a system of linear equations to
nickels and dimes in your pocket. Let x represent the number of nickels and let y represent the number of dimes.
System of equations
There are
nickels in your pocket and
dimes in your pocket
Answer:
6 nickels and 4 dimes
Step-by-step explanation:
6 times .05 is .30
4 times .10 is .40
just add them
.40 + .30 = .70
The equation should be:
.70 = .10y + .05x
I have 4 dimes and 6 nickels.
The question is ill-formatted. The following is the question.
You have a total of ten coins in your pocket, all of which are nickels and dimes. The total value of the coins is $0.70. To find nickels and dimes in your pocket, write and solve a system of linear equations. Let x represents the number of nickels and let y represent the number of dimes. Find the number of nickels and dimes.
How much is a cent?One-hundredth of a dollar is equivalent to one cent.
How much is a nickel?A nickel is worth 5 cents. That means $0.05.
How much is a dime?A dime is worth 10 cents. That means $0.10.
How to solve the question?As per the question,
conversion of the statements into mathematical equations:
"You have a total of ten coins in your possession, all of which are nickels and dimes."Subtracting the above equation from the below equation we get y=4.
And by substituting y=4 in x+y=10 we get x=6.
Hence, I have 4 dimes and 6 nickels.

A family has three children.The oldest is 4 years older than the middle,and the youngest child is 2 years younger than the middle child.The sum of the ages of the children is 26.
Answer:
The age of the youngest child = x = 6 years
The age of middle child = y = 8 years
The age of the oldest child = z = 12 years
Step-by-step explanation:
Let us represent:
The age of the youngest child = x
The age of middle child = y
The age of the oldest child = z
The sum of the ages of the children is 26.
Hence: x + y + z = 26...... Equation 1
The oldest is 4 years older than the middle
z = 4 + y
The youngest child is 2 years younger than the middle child
x = y - 2
Hence, we substitute 4 + y for z and y - 2 for x in Equation 1
x + y + z = 26...... Equation 1
y - 2 + y + 4 + y = 26
y + y + y -2 +4 = 26
3y + 2 = 26
Subtract 2 from both sides
3y + 2 - 2 = 26 - 2
3y = 26 - 2
3y = 24
y = 24/3
y = 8
Solving for x
x = y - 2
x = 8 - 2
x = 6
Solving for z
z = 4 + y
z = 4 + 8
z = 12
Therefore:
The age of the youngest child = x = 6 years
The age of middle child = y = 8 years
The age of the oldest child = z = 12 years
