A figure is made up of one square and one triangle. The square has a side Length of 13 feet. The triangle has a base of 13 feet and a height of 8.2 feet. What is the total area of the figure.
Which equation represents a line that passes through (0,–8) and (–5,–23)?
A) y = 4x – 8
B) y = –8x + 3
C) y = 5x – 8
D) y = 3x – 8
The equation of line that passes through points (0,-8) and (-5,-23) is y=3x-8 which is option d.
Given that the line passes through (0,-8) and (-5,-23).
We are required to find the equation of the line that passes through (0,-8) and (-5,-23).
Equation is like a relationship between two or more variables expressed in equal to form. Equation of two variables look like ax+by=c. It may be linear equation, quadratic equation, cubic equation, and many more depending on the power of the variable.
The formula to form the equation from two points is as under:
[tex](y-y_{1}) =(y_{2} -y_{1} )/(x_{2} -x_{1} ) * (x-x_{1} )[/tex] in which [tex](x_{1} ,y_{1} ),(x_{2} ,y_{2} )[/tex] are the points.
(y+8)=(-23+8/-5-0)(x-0)
y+8=(-15/-5) x
y+8=3x
y=3x-8
Hence the equation of line that passes through points (0,-8) and (-5,-23) is y=3x-8 which is option d.

What a deal! Just deShirts is having a 20% off sale. Trixie rushes to the store and buys 14 shirts. When the clerk rings up her purchases, Trixie sees that the clerk has added the 5% sales tax first, before taking the discount. Trixie wonders whether adding the sales tax before the discount makes her final cost more than adding the sales tax after the discount. Without making any calculations, make a conjecture. Is Trixie getting charged more when the clerk adds sales tax first? The next few problems will help you figure it out for sure.
Does it matter if sales tax is added before the discount or after her final total? (Yes or no AND why or why not?)
Answer:
no because she would get the same total if she added it before or after
