Using a system of linear equation to represent the problem given, there are 12 incorrect answers given
Points per correct score = 5 Points deducted per incorrect score = 3 Number kd questions answered = 40Let :
Number of correct answers = cWe could create an equation thus:
5(c) - 3(40 - c) = 104
Expand
5c - 120 + 3c = 104
8c = 104 + 120
8c = 224
c = (224 ÷ 8)
c = 28
Number of incorrect answers = 40 - 28 = 12
Therefore, there are 12 incorrect answers

What is the equation, in point-slope form, for a line that goes through(8, −4) and has a slope of −5/6?
Answer:
[tex]y = \frac{-5}{6} x + 2\frac{2}{3}[/tex]
Step-by-step explanation:
Use the Point-Slope formula...
(y - (-4)) = -5/6(x - 8)
Simplify
y + 4 = -5/6x + [tex]6\frac{2}{3}[/tex]
y = -5/6 + 2 2/3

6. What is the area of a rectangular floor that is 7-3" long
and 4-2” wide?
The area of the rectangle will be 4350 Inches squared.
What is the area of the rectangle?The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rectangle in a two-dimensional plane is called the area of the rectangle.
Given that a rectangular floor is 7-3" long and 4-2” wide. Here 7 ft 3 in = 87 in. 4ft 2 in = 50 in.
The area of the rectangle is calculated by using the formula below:-
Area = Length x Width
Area = 87 x 50
Area = 4350 Inches
Therefore, the area of the rectangle will be 4350 Inches squared.

What is the absolute value function?
a. y= 7 |x+8| -4
b. y= -7 |x-8| +4
c. y= -7 |x+8| -4
d. y= -7 | x-8| -4
PLEASE HELP PLEASE PLEASE PLEASE
Answer:
c
Step-by-step explanation:
The absolute value function would be;
b. y= -7 |x - 8| +4
Given that;
The functions are,
a. y= 7 |x+8| -4
b. y= -7 |x-8| +4
c. y= -7 |x+8| -4
d. y= -7 | x-8| -4
Since, The absolute value function is a mathematical function that returns the positive magnitude or value of a given number, disregarding its sign. It is denoted by enclosing the number within vertical bars (| |).
In the given options, the equation that represents the absolute value function is:
b. y = -7 |x - 8| + 4
This equation represents a downward-opening V-shaped graph with its vertex at (8, 4).
As x approaches 8 from the left, the value of y decreases.
As x moves away from 8 towards positive or negative infinity, the value of y increases.
Therefore, the correct option is (b).

$16,974.50
Step-by-step explanation:
$14,382.50+24% of the amount over $84,200 is ...
$14,382.50 +0.24×(95,000 -84,200) = $14,382.50 +2592.00 = $16,974.50
Mustafa owes $16974.50 in federal income tax.

Additional comment
Each row of the tax table can be simplified by multiplying out the expression it describes. For the row applicable to this problem, that becomes ...
14382.50 +0.24(amount -84200) = 14382.50 +0.24×amount -20208
= 024×amount -5825.50

Find the value of f(3) y=f(x)
9514 1404 393
Answer:
-4
Step-by-step explanation:
On a graph like this where not every grid line is marked with its value, you have to determine the spacing of the grid lines by noting how many are between the values shown. Here, the vertical grid lines are marked on the x-axis with even numbers on every other line. That means the lines not numbered have a value halfway between the values on the lines that are numbered.
The grid line for x = -3 is the one halfway between the grid lines for -2 and -4. Following that line down to where it intersects the function graph, we find the y-coordinate of that (vertex) point to be -4. (It is on a marked horizontal grid line, so you can read the value from the axis scale.)
The value of f(-3) is -4.
