Answer:
5
Step-by-step explanation:
In the slope- intercept form of y= mx +b, m is the slope and b is the y- intercept.
Let's find the slope using the formula below:
[tex]\boxed{slope = \frac{y1 - y2}{x1 -x 2} }[/tex]
[tex]m = \frac{3 - ( - 3)}{1 - 4} [/tex]
[tex] m = \frac{3 + 3}{ - 3} [/tex]
[tex]m = \frac{6}{ - 3} [/tex]
m= -2
Substitute m= -2 into the equation:
y= -2x +b
To find the value of b, substitute a pair of coordinates into the equation:
When x= 1, y= 3,
3= -2(1) +b
3= -2 +b
b= 3 +2 (+2 on both sides)
b= 5
Thus, the 4th option is correct.
A manufacturer produces jeans in 9 sizes, 7 different colors, and 6 different stitching patterns. If a
branch store manager orders two pairs of each possible type, how many pairs of jeans will he expect to have delivered?
Answer: 756 pairs
Step-by-step explanation: 9*7*6 = 378 difference jeans Times 2 since we want 2 pair of each possibility = 756 jeans delivered.
The number of pairs of jeans will he expects to have delivered will be 756.
What is the combination?The arrangement of the different things or numbers in a number of ways is called the combination.
A combination in mathematics is a choice made from a group of separate elements where the order of the selection is irrelevant.
It is given that a manufacturer produces jeans in 9 sizes, 7 different colors, and 6 different stitching patterns.
The number of pairs of jeans will he expects to have delivered will be calculated as below:-
9 x 7 x 6 = 378
Two pairs of each will be,
378 x 2 = 756.
Therefore, the number of pairs of jeans will he expects to have delivered will be 756.

13. You are debating about whether to buy a new computer for $800.00 or refurbished computer with the same equipment for $640.00. If you are paid
$10.00/hour and your deductions
are FICA (7.65%), federal tax withholding (12%), and state tax withholding (8%), how many hours do you have to work to pay for the new computer?
89 hours
•
98 hours
•
87 hours
•
111 hours
The number of hours to work to pay for the new computer is 111 hours
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
The cost difference between the new and refurbished computer is $800.00 - $640.00 = $160.00. This means that you would save $160.00 by buying the refurbished computer instead of the new one.
Let's say you work for "x" hours, then your gross pay will be:
A = 10x dollars
Your FICA deduction will be 7.65% of your gross pay:
0.0765 ( 10x ) = 0.765x dollars
Your federal tax withholding will be 12% of your gross pay:
0.12 ( 10x ) = 1.2x dollars
Your state tax withholding will be 8% of your gross pay:
0.08 ( 10x ) = 0.8x dollars
The total amount of taxes that will be deducted from your paycheck is the sum of these three amounts:
0.765x + 1.2x + 0.8x = 2.765x dollars
So your net pay will be:
10x - 2.765x = 7.235x dollars
On simplifying the equation , we get
Now, we can calculate the number of hours you would need to work to pay for the new computer:
800 = 7.235x
x ≈ 110.5 hours
Hence , the number of hours is x = 111 hours
