Emerson purchased a game that was on sale for 18% off. The sales tax in his county is 8%. Let y represent the original price of the game. Write an expression that can be used to determine the final cost of the game.
Using decimal multipliers, it is found that the expression that can be used to determine the final cost of the game is given by:
[tex]C = 0.8856y[/tex]Decimal multipliers:The equivalent multiplier for an increase of a% is given by: [tex]\frac{100 + a}{100}[/tex]The equivalent multiplier for an decrease of a% is given by: [tex]\frac{100 - a}{100}[/tex]In this problem:
Purchase for 18% off, hence decrease of 18%, that is, [tex]\frac{100 - 18}{100} = 0.82[/tex].Sales tax of 8%, hence, an increase of 8%, that is, [tex]\frac{100 + 8}{100} = 1.08[/tex].Applying both multipliers, the expression is:
[tex]C = y(0.82)(1.08) = 0.8856y[/tex]

Answer: 100 99/100
Step-by-step explanation: add the 1/2 and 1/5 together by finding a common denominator(10). 1/2 would become 5/10 and 1/5 would become 2/10. 2/10 + 5/10 =7/10. now we're left with (7/10)^2 +3/10 x 5
to do (7/10)^2 you square the top and bottom to give you 49/100.
next we'll do 3/10 x 5 which would equal 15/10. so now all we have left to do is add 49/100 and 15/10. to do this we'll find a common denominator of 100. so well multiply the top and bottom by 10 to give you 150/100.
finally, 49/100 + 150/100 = 199/100 or as a mixed number, 100 99/100
Answer:
1[tex]\frac{99}{100}[/tex]
Step-by-step explanation:
I would start by turning the parentheses fractions into one fraction.
You could do binomial multiplication and get [tex]a^{2} +2ab+b^{2}[/tex] but it might take longer.
So I would just turn them into one fraction by finding the common denominator.
The common denominator here is 10
[tex]\frac{1}{5} (\frac{2}{2} )=\frac{2}{10}[/tex]
[tex]\frac{1}{2} (\frac{5}{5} )=\frac{5}{10}[/tex]
Now add
[tex]\frac{2}{10} +\frac{5}{10} =\frac{7}{10}[/tex]
Now apply: [tex](\frac{a}{b} )^{2} =\frac{a^{2} }{b^{2} }[/tex]
[tex](\frac{7}{10} )^{2} =\frac{7^{2} }{10^{2} } =\frac{49}{100}[/tex]
Now, multiplying the other fraction we get [tex]\frac{3}{10} (5)=\frac{15}{10}[/tex]
Now turn this into a fraction with denominator 100 to add the two fractions
[tex]\frac{15}{10} (\frac{10}{10} )=\frac{150}{100}[/tex]
[tex]\frac{49}{100} +\frac{150}{100} =\frac{199}{100} =1\frac{99}{100}[/tex]
There is also another method to add or subtract fractions without multiplying to get a common denominator in case you are interested:
[tex]\frac{a}{b}[/tex]±[tex]\frac{c}{d}[/tex]=[tex]\frac{ad+bc}{bd}[/tex]

Answer:
1 5/8 is equal to 13/8
Step-by-step explanation:
What is the remainder R?
What is remainder R when the polynomial p(x) is divided by (2x - 1)? is (2x - 1) factor of p(x)?
p(x) = 2x² + 3x + 1
Answer :
R = 3
and (2x - 1) not factor of p(x) because, if (2x - 1) factor of p(x) remainder R when the polynomial p(x) divided by (2x - 1) is R = 0

Graph the line that passes through the points (-5, 3) and (−1,−1) and determine the equation of the line.
A line can be drawn by joining the plot of the two given points
Please find attached the graph of the line created with MS ExcelThe equation of the line is y = -x - 2Reason:
Given points on the line are (-5, 3) and (-1, -1)
From the given points, the graph of the line can be plotted with MS ExcelThe slope, m, of the line is given as follows
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Therefore, we have;
[tex]Slope, \, m =\dfrac{-1 - 3}{-1 - (-5)} = \dfrac{-4}{4} = -1[/tex]
The equation of the line in point and slope form is therefore;
y - 3 = -1·(x - (-5) = -x - 5
In slope and intercept form, we have;
y = -x - 5 + 3 = -x - 2
The equation of the line in slope and intercept form is y = -x - 2Learn more here:

5. Rewrite the quadratic funtion from standard form to vertex form.
Ax) = 2x2 + 8x + 70
Answer:
[tex]y = 2 {(x + 2)}^{2} + 62[/tex]
Step-by-step explanation:
vertex form is
[tex]y = a {(x - h)}^{2} + k \\ where \: (h. \: k) \: is \: the \: vertex[/tex]
our original equation
[tex]2 {x}^{2} + 8x + 70[/tex]
first we will find the x value using the formula
[tex]x = - \frac{b}{2a} \\ - \frac{8}{2(2)} = - \frac{8}{4} = - 2 \\ x = - 2 = h[/tex]
plug the value of x back into the original equation to solve for y
[tex]y = 2 {x}^{2} + 8x + 70 \\ y = 2 ({ - 2}^{2} ) + 8( - 2) + 70 \\ y = 2(4) - 16 + 70 \\ y = 8 - 16 + 70 \\ y = 78 - 16 \\ y = 62 = k[/tex]
substitute this back into our vertex form and not forgetting the coefficient a = 2
[tex]y = 2 {(x - ( -2))}^{2} + 62 \\ y = 2 {(x + 2)}^{2} + 62[/tex]

Step-by-step explanation:
work out the value of x. 3x? x?
Answer:
x = 67.5
Step-by-step explanation:
Exterior angles always add up to 360 degrees. We have a defined right angle which takes 90 off of our 360, giving us 270 degrees. If we have x as an individual angle and also as x 3 times, then x is appearing 4 times. To find x, we divide our 270 degrees by 4 to get 67.5 . We can check this using a reversive property by multiplying 67.5 by 4 and then adding 90.
360 - 90 = 270
270 / 4 = 67.5
67.5 = x

1. Obtén la pendiente de las siguientes rectas, grafícalas y determina si las rectas L1 y L2, cuyas ecuaciones son 3x+4y-2=0 y 3x+4y+6=0, son paralelas o no.
Queremos obtener la pendiente de dos lineas dadas, y en base a eso, determinar si son paralelas o no.
Las pendientes son para ambas lineas igual a -3/4, como ambas lineas tienen la misma pendiente y diferente ordenada al origen, podemos concluir que son paralelas.
-----------------------------
Una línea en general se escribe como:
y = a*x + b
Donde a es la pendiente y b es la ordenada al origen.
En este problema se nos dan las líneas:
3*x + 4*y - 2 = 0
3*x + 4*y + 6 = 0
Comencemos por reescribir esas líneas en la forma más general, para hacer esto, debemos aislar y en ambas ecuaciones:
y = (-3/4)*x + 2/4
y = (-3/4) - (6/4)
Aqui podemos ver que ambas pendientes son iguales a -3/4
Al final de la respuesta puedes ver el gráfico de ambas líneas.
Como ambas líneas tienen la misma pendiente, pero distintas ordenadas al origen, podemos concluir que son paralelas.
Esto mismo se puede observar en el gráfico de abajo.

Red oak trees grow at a rate of about 2 feet per year. You buy and plant two red oak trees, one that is 6 feet tall and one that is 8 feet tall. The height h (in feet) of the shorter tree can be modeled by h=2t+6 where t is the time (in years) since you planted the tree. The height of the taller tree can be modeled by h=2t+8.
A. Graph both equations in the same coordinate plane.
B. Use the graphs to find the difference of the heights of the trees 5 years after you plant them. What is the difference after 10 years? What do you notice about the difference if the heights of the two trees?
Answer:
A: I think it's A because you need to graph both equations
Answer:
These are the screenshots of the work I did and more of the actual answer for graphing but basically,
The difference in heights of the trees after 5 years is 2 feet, after 10 years is 2 feet, and after any number of years is 2 feet since the lines are parallel.
