Answer:
[tex]\Large\boxed{\sf Slope\ =0}[/tex]
Step-by-step explanation:
Considering two points [tex]\sf A(x_A, y_A)[/tex] and [tex]\sf B(x_B, y_B)[/tex], the slope of the line that passes through A and B is given by [tex]\sf m=\frac{y_B-y_A}{x_B-x_A}[/tex].
Given :
A(-2,-3)B(4,-3)Now we can calculate the slope with the previous formula :
[tex]\sf m=\frac{-3-(-3)}{4-(-2)}[/tex]
[tex]\sf m=\frac{0}{6}[/tex]
[tex]\boxed{\sf m=0}[/tex]
The slope of the line is 0.

How can you change the grouping of the addends. $5.50+$7.83+$3.50 what can they be changed to
They way you can change the grouping of the addends. in $5.50+$7.83+$3.50 is; $5.50 + ($7.83 + $3.50) = ($5.50 + $3.50) + $7.83
How to interpret Algebra Properties?There are different algebraic properties such as;
Commutative Property
Associative Property
Distributive Property
Now, the commutative property states that the change in the order of two numbers in an addition or multiplication operation does not change the sum or the product. For example;
a + b + c = c + a + b or a* b = b * a
Now, the associative property states that the way in which factors are grouped in a multiplication or addition problems does not change the product. For example; x + (y + z) = (x + z) + y
Now, to our question, one way to group the addends using associative property is;
$5.50 + ($7.83 + $3.50) = ($5.50 + $3.50) + $7.83

The average number of viewers over the two week is D. 4.85 x 10^5.
How to calculate the value?It should be noted that the scientific notation simply has to do with writing of numbers that are either too large or too small. This will be illustrated thus:
In this case, the TV show had 5.6 x 10^5 viewers in the first week and 4.1 x 10^5 viewers in the second week.
Therefore, the average number of viewers over the two weeks will be:
= (5.6 × 10^5) + (4.1 × 10^5) / 2
= 4.85 × 10^5
Note that we had to divide by 2 since it's average.

the amount of sales tax paid on a purchase is proportional to the price of the item. suppose the sales tax rate is 6.25%. if p is the price of the item and t is the sales tax, which equation represents this?
The equation which represents the amount is p = 0.0625 t.
When a consumer buys a good or service from a retailer, sales tax, which is estimated as a percentage, is added to the cost of the item.
Sales tax rate = sales tax percent / 100.
Sales tax = list price * sales tax rate.
Total price including tax = list price + sales tax,
Total price including tax = list price + (list price * sales tax rate),
Total price including tax = list price * ( 1 + sales tax rate)
We have been given
sales tax rate = 6.25%.
The price of the item = p
The sales tax = t
We know that the amount of sales tax paid on a purchase is proportional to the price of the item.
p = 6.25% t
p = 6.25/100 t
p = 0.0625 t.
Hence , P = 0.0625 t is the equation used to represent the amount.

Answer:
[tex]tan(x)=\frac{44\sqrt{89}}{89}[/tex]
Step-by-step explanation:
tan is defined as: [tex]tan(x)=\frac{opposite}{adjacent}[/tex]
sin is defined as: [tex]sin(x)=\frac{opposite}{hypotenuse}[/tex]
cos is defined as: [tex]cos(x)=\frac{adjacent}{hypotenuse}[/tex]
We can also define tan as: [tex]tan(x)=\frac{sin(x)}{cos(x)}[/tex]
because plugging in the definitions of sin and cos in we get: [tex]tan(x)=\frac{(\frac{opposite}{hypotenuse})}{(\frac{adjacent}{hypotenuse})}\\\\tan(x)=\frac{opposite}{hypotenuse}*\frac{hypotenuse}{adjacent}\\\\tan(x)=\frac{opposite}{adjacent}[/tex]
which you'll notice is the original definition of tan(x)
So using this definition of tan(x) we can use the givens sin(x) and cos(x) to find tan(x)
[tex]sin(x)=\frac{44}{45}\\\\cos(x)=\frac{\sqrt{89}}{45}\\\\tan(x)=\frac{sin(x)}{cos(x)}[/tex]
plugging in sin(x) and cos(x) we get:
[tex]tan(x)=\frac{\frac{44}{45}}{\frac{\sqrt{89}}{45}}\\\\tan(x)=\frac{44}{45}*\frac{45}{\sqrt{89}}\\\\tan(x)=\frac{44}{\sqrt{89}}[/tex]
We usually don't like square roots in the denominator, and from here we want to rationalize the denominator which we do by removing the square root from the denominator.
We can do this by multiplying the fraction by: [tex]\frac{\sqrt{89}}{\sqrt{89}}[/tex] which doesn't change the value of the fraction since it simplifies to 1, but it gets rid of the square root in the denominator
[tex]tan(x)=\frac{44}{\sqrt{89}}*\frac{\sqrt{89}}{\sqrt{89}}\\\\tan(x)=\frac{44\sqrt{89}}{89}[/tex]

One example of application of proportions is for percentage problems, as the total amounts are multiplied by the decimal equivalent of the percentage to find the equivalent amounts.
The planes in Los Angeles after 8 hours are given as follows:
70% of 30 (that were already in Los Angeles).25% of 12(planes that were in St. Louis).12.5% of 8(planes that were in Dallas).Hence the amount is:
0.7 x 30 + 0.25 x 12 + 0.125 x 8 = 25.
The planes in St. Louis after 8 hours are given as follows:
20% of 30 (planes that were in Los Angeles).25% of 12(planes that were already in St. Louis).50% of 8(planes that were in Dallas).Hence the amount is:

A skateboard in a
store in Charlottetown, PEI, costs
$39.99. It is on sale for 30% off.
The taxes are 16%. What is the sale
price of the skateboard including taxes?
A student says, “$39.99 – 30% discount
+ 16% taxes is the same as calculating
$39.99 – 14%.”
Is the student’s reasoning correct?
Answer:
No, the reasoning is not correct.
Step-by-step explanation:
39.99 x .14 = 5.5986 Does it make sense that the sales price plus the tax would be $5.60? Doesn't that seem really low?
39.99 x .3 = 11.997 is the amount that we are taking off of the original price.
39.99 - 12 (Rounded to the nearest cent) is 27.99.
Now we pay the tax on the discounted amount of the item.
27.99 x .16 = 4.4784 or 4.48 rounded to the nearest cent.
The out the door cost of the item
is 27.99 + 4.48 = 32.48
