What is the equation in point slope form of the line that passes through the point (3, 1) and has a slope of –2?
Drag and drop the appropriate number, symbol, or variable to each box.
Answer:
y - 1 = -2(x - 3)
Step-by-step explanation:
Given the point, (3, 1) and the slope of –2:
Let (x₁, y₁) = (3, 1)
slope: m = -2
Substitute these values into the following point-slope form:
y - y₁ = m(x - x₁)
y - 1 = -2(x - 3) ⇒ This is the point-slope form.

Calculate the size of angle x.
angle x =
The size of angle x from the figure is 16 degrees
The sum of the interior angle of a triangle is 180 degrees, hence to get the value of X, we will take the sum of all the given angles and equate them to 180 degrees.
127 + 37 + X = 180
164 + x = 180
Subtract 164 from both sides
164 + x - 164 = 180 - 164
x =16 degrees
Hence the size of angle x from the figure is 16 degrees

Answer:
Solution :As we know that the sum of interior angles of triangle is 180⁰.
Accounting to the question :
[tex]\implies[/tex] Sum of angles = 180⁰
[tex]\implies[/tex] 127⁰ + 37⁰ + X = 180⁰
[tex]\implies[/tex] 164⁰ + X = 180⁰
[tex]\implies[/tex] X = 180⁰ - 164⁰
[tex]\implies[/tex] X = 16⁰
Hence, the size of angle is 16⁰.

Equivalent Expression: [tex]\displaytext\mathsf{\frac{a^7}{b^8}}[/tex]
Step-by-step explanation:
Given the exponential expression, [tex]\displaystyle\mathsf{\frac{a^{12}\:b^{-3}}{a^{5}\:b^{5}}}[/tex]:
We could use the Quotient Rule of Exponents where it states that:
[tex]\displaystyle\mathsf{\frac{a^m}{a^n}\:=\:a^{(m\:-\:n)}}[/tex]
Since we have the variables, a and b as the base, we could simply apply the Quotient Rule and subtract their exponents.
[tex]\displaystyle\mathsf{\frac{a^{12}\:b^{-3}}{a^{5}\:b^{5}}\:=\:a^{(12\:-\:5)}\:b^{(-3\:-\:5)}}[/tex]
[tex]\displaytext\mathsf{=\:a^{7}\:b^{-8}}[/tex]
Next, we must transform the negative exponent of base, b, into positive by applying the Negative Exponent Rule, where it states that:
[tex]\large\text{$ a^{-n}\:=\:\frac{1}{a^{n}} $}[/tex]
Applying the Negative Exponent Rule will result in the following exponential expression:
[tex]\LARGE\text{$ a^{7}\:b^{-8}\:=\:[a^{7}\:\times\:\frac{1}{b^8}]\:=\:\frac{a^7}{b^8} $}[/tex]
Therefore, the equivalent expression is: [tex]\LARGE\text{$ \frac{a^7}{b^8} $}[/tex].
rewrite the equation in Ax+By=C form, use intergers for A, B, and C.
Answer:
2x - y = - 8
Step-by-step explanation:
y - 4 = 2(x + 2) ← distribute
y - 4 = 2x + 4 ( subtract y from both sides )
- 4 = 2x - y + 4 ( subtract 4 from both sides )
- 8 = 2x - y , that is
2x - y = - 8 ← in standard form
with A = 2, B = - 1 and C = - 8

3(x + y) + 5x + y
Answer:
8x + 4y
Step-by-step explanation:
3(x + y) + 5x + y
3x + 3y + 5x + y....... distribute 3 to both variables in the parenthesis
8x + 4y....................... combine like terms
Answer
8x+4y
Step-by-step explanation:
First you expand the 3(x+y) by multiplying 3 with x+y
So it becomes 3x+3y
Now your new expression will be 3x+3y+5x+y
After that, you combine the like terms, 3x and 5x are like terms, 3y and y are like terms.
So it will become 3x+5x+3y+y
You can add the like terms up, so 3x+5x=8x and 3y+y =4y
The simplified expression will be 8x+4y

An online game site has two memership plans. The first plan gives you unlimited play for $40 a month. The second plan charges a monthly access fee of $4.25 plus $2.75 for each hour you play. After how many hours do the two plans cost the same?
Answer:
after 13 hours
Step-by-step explanation:
Since the monthly fee is $4.25
so
● $4.25 + ( 2.75 × Number of hours) = 40
● ( 2.75 × Number of hours) = $40 - $4.25
● 35.75/ 2.75 = 13

One angle of a triange is 19 degrees, a second angle is 98 degrees. What is the measurement of the third angle?
Answer:
63°
Step-by-step explanation:
Angle sum property = 180°
=> 19 + 98 + x = 180
=> x = 180 - 117 = 63°
Answer:
63°Step-by-step explanation:
Given,
Measurement of one angle of a triangle = 19°
Measurement of 2nd angle of the triangle = 98°
Let,
The third angle be = x
As we know,
Sum of all the angles of a triangle is 180°
Therefore,
By the problem,
=> 19° + 98° + x = 180°
(On shifting like terms to one side )=> x = 180 - 98 - 19
(On subtracting)=> x = 63
Hence,
The measurement of 5he third angle of the triangle is 63° (Ans)

Restaurant industry food and drink sales y (in billions of dollars) in a certain country from 2008 through 2017 can be approximated by the equation y= 3x² + 3.2x + 514,
where x is the number of years since 2008. Assume that this trend continues and predict the year in which the restaurant industry food and drink sales will be $1212
billion.
The year in which the restaurant industry food and drink sales will be $1212 billion is
(Round to the nearest whole number as needed.)
The given quadratic function for the restaurant sales indicates that the sale first reduces then increases.
The year at which the restaurant sale will be $1212 billion is approximately the year 2023.Reasons:
The function for the sales in the restaurant is y = 3·x² + 3.2·x + 514
Where;
y = Sales in billions of dollars
x = Number of years since 2008
Required:
The year in which the restaurant industry food and drink sales will be $1212 billion.
Solution:
When the food and drink sale is $1212 billion, we have;
1212 = 3·x² + 3.2·x + 514
Which gives;
3·x² + 3.2·x + 514 - 1212 = 0
3·x² + 3.2·x - 698 = 0
Factorizing with a graphing calculator gives;
(x + 15.796)·(x - 14.729) = 0
x = -15.796, or x = 14.729
The time will have a natural number value, therefore the positive value of x
= 14.729 is used.
Therefore, the number years since 2008 at which the restaurant sales will
be $1212 billion is approximately 15 years.
The year at which the sales will be $1212 billion = 2008 + 15 = 2023

Athlete J runs 2/3 of a mile in 8 minutes. Athlete H runs 2 3/4 miles in 1/2 hour.
1. If Athlete J continues at that speed, how long will it take to run one mile?
2.How long will it take Athlete J to run 5 miles at that same speed?
3.Who runs faster, Athlete J or Athlete H? Explain your answer.
If Athlete J continues at that speed, it will take 12 minutes to run 1 mile
It will take Athlete J 60 minutes to run 5miles
Since the speed of Athlete H is greater than that of J, hence Athlete H runs faster.
The formula for calculating the speed of the athlete is expressed as:
Speed = Distance/Time
1) If Athlete J runs 2/3 of a mile in 8 minutes, this can be expressed as:
2/3 miles = 8 minutes
If the athlete runs for 1 mile, then;
1 mile = x
Divide both expressions
2/3 = 8/x
2x = 24
x = 12 minutes
Hence If Athlete J continues at that speed, it will take 12 minutes to run 1 mile
2) if athlete J run 5 miles, the time taken will be expressed as;
2/3(5) = 8/x
2/15 = 8/x
2x = 120
x = 60minutes
Hence it will take Athlete J 60 minutes to run 5miles
3) If Athlete H runs 2 3/4 miles in 1/2 hour, then the speed of athlete H will be expressed as:
Speed = (2 3/4)/0.5
Speed = 2.75/0.5
Speed = 5.5miles/hr
For Athlete J;
Speed = 5/1
Speed = 5 miles/hr
Since the speed of Athlete H is greater than that of J, hence Athlete H runs faster.
