A. Y+3=5(x-8)
B. Y+3=5x-8
C.y-3=5(x-8)
D.y-3=5(x+8)
Option C is correct, y-3=5(x-8) is the equation in point slope form for the line through the given point with the given slope
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The point slope form of a line is y-y₁=m(x-x₁)
We need to find equation in point slope form for the line through the given point (8,3) with the given slope m =5
y-3=5(x-8)
Hence, option C is correct, y-3=5(x-8) is the equation in point slope form for the line through the given point with the given slope

Jose has had his eye on a pair of basketball shoes at a shoe store for a long time, but at a price of $150, the shoes have always been a little bit more than his budget could handle. However, today he saw a sign in the window that said, "Basketball Shoes – 20% off." Which type of discount is this?
A. A sale
B. A coupon
C. A rebate
D. A gift card
This type of a discount is:
A. A sale
Step-by-step explanation:Sale--
A sale is a transaction between two parties one is a buyer and other is seller in which the goods or services are provided by the seller at a lower rate as compared to the normal price of it.
The price so lowered is known as a discounted price and the price at which the item is to be sold is known as a sale price.
Here the store is keeping the basketball shoes at a sale which is displayed on window as:
"Basketball Shoes – 20% off."
Hence, the correct option is: Option: A

How far does the first car will drive in the 2 hours head start it gets? Now, at t = 2 hours, both cars are moving. How much faster is the second car than the first car? You can determine this by dividing the head start by the difference in the two speeds. If car 1 has a 20-mile head start, and car two is five mph faster, then it will take 20/5 = 4 hours to catch up.

Jack and Walter work in a store's gift-wrapping department. Jack can wrap 28 boxes in 2 hours, while Walter takes 3 hours to wrap 36 boxes of the same size. One day they work together for t hours to gift wrap 65 boxes. Which equation models this situation?
Answer: They work for 2.5 hours to gift wrap 65 boxes.
Step-by-step explanation:
Since we have given that
Number of boxes Jack can wrap = 28
Time taken by him = 2 hours
Number of boxes Walter can wrap = 36
Time taken by him = 3 hours
Work done by Jack in 1 hour is given by
[tex]\frac{2}{28}\\\\=\frac{1}{14}[/tex]
Work done by Walter in 1 hour is given by
[tex]\frac{3}{36}\\\\=\frac{1}{12}[/tex]
So, Work done by both Jack and Walter in 1 hour is given by
L.C.M. of [tex](\frac{1}{14},\frac{1}{12})[/tex] is [tex]=\frac{l.c.m.\ of \ numerator}{h.c.f\ of\ denominator}=\frac{1}{2}[/tex]
Number of units done by Jack is given by
[tex]\frac{\frac{1}{2}}{\frac{1}{14}}\\\\=\frac{14}{2}\\\\=7\ units[/tex]
Number of units done by Walter is given by
[tex]\frac{\frac{1}{2}}{\frac{1}{12}}\\\\=\frac{12}{2}\\\\=6\ units[/tex]
So, Let the number of hours be 't' .
[tex]7t+6t=\frac{1}{2}\times 65\\\\13t=\frac{1}{2}\times 65\\\\t=\frac{1}{2}\times \frac{65}{13}\\\\t=\frac{5}{2}\\\\t=2.5\ hours[/tex]
So, They work for 2.5 hours to gift wrap 65 boxes.

Change this radical to an algebraic expression with fractional exponents.
√x^3
Final answer:
To express[tex]\(\sqrt{x^3}\)[/tex] as a fractional exponent, it is rewritten as[tex]\(x^{\frac{3}{2}}\),[/tex] correlating the square root operation to the power of \[tex](\frac{1}{2}\)[/tex]and multiplying by the exponent 3.
Explanation:
To change the radical[tex]\(\sqrt{x^3}\)[/tex]to an algebraic expression with fractional exponents, we can use the property that any root can be expressed as a power with a fractional exponent. The square root of a variable to some power can be represented by raising the variable to the power of half the original exponent.
In this case,[tex]\(\sqrt{x^3}\)[/tex]can be written as [tex]\(x^{\frac{3}{2}}\).[/tex] This is because the square root operation is equivalent to raising to the power of[tex]\(\frac{1}{2}\),[/tex] and when we multiply the exponents [tex]\(3 \times \frac{1}{2}\),[/tex] we get[tex]\(\frac{3}{2}\).[/tex]

...?
The results of the expression are 8 2/7 ; 16.286 and 16 respectively.
Using the expression given :
456 / 28Now we divide:
A.)
456 / 28 = 16 remainder 8
Now we have :
8 8/28
= 8 2/7
B.)
As a decimal :
456 / 28
= 16.286
C.)
Rounded to the nearest whole number:
456 / 28
= 16.286
≈ 16
Final answer:
To divide 456 by 28: as a mixed number is 16 2/7, as a decimal rounded to two places is 16.29, and to the nearest whole number is 16.
Explanation:
To divide 456 by 28, we start by performing the division to find the quotient and the remainder. Firstly, 456 divided by 28 equals 16 with a remainder of 8.
Answering the three parts:
A. As a mixed number, we have 16 and 8/28. Simplifying the fraction 8/28 to its lowest terms, we get 2/7. Thus, the mixed number is 16 2/7.B. To express the quotient as a decimal rounded to two decimal places, 456 divided by 28 equals approximately 16.29.C. The quotient, rounded to the nearest whole number, is 16.The information provided seems to be examples of rounding and significant figures from various arithmetic operations but does not directly relate to the division of 456 by 28, which is our primary focus. Please note that while rounding to the nearest whole number or to two decimal places, it's important to correctly evaluate the quotient that the specific calculation yields.
