Find a point-slope form for the line with slope 1/5 and passing through the point (-8, - 9).
The equation of the line in point-slope form is ______?
Answer:
y=1/5(x+8)-9
Step-by-step explanation:
Point Slope Formula: y=m(x-x1)+y
y=1/5(x+8)-9
Answer:
[tex]y+9=\frac{1}{5} (x+8)[/tex]
Step-by-step explanation:
Pre-SolvingWe are given that a line has a slope (m) of 1/5, and passes through the point (-8, -9).
We want to write the equation of this line in point-slope form.
Point-slope form is given as [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1,y_1)[/tex] is a point.
Pre-SolvingAs we are given both the slope and the point, we can plug those values into the equation.
Starting with the slope, we can replace m with 1/5.
[tex]y-y_1=\frac{1}{5} (x-x_1)[/tex]
Now, substitute -8 as [tex]x_1[/tex] and -9 as [tex]y_1[/tex]. We get:
[tex]y--9=\frac{1}{5} (x--8)[/tex]
This can be simplified to:
[tex]y+9=\frac{1}{5} (x+8)[/tex]

5.) The temperature drops from 9 degrees F to -5 degrees. By how much
does the temperature drop?
Answer:
The temperature dropped 14 degrees.
Step-by-step explanation: x = 14
x + (-5)= 9
The absolute value (distance from zero) of -5 is 5.
The absolute value of 9 is 9.
To find the drop in temperature, add the absolute values of both numbers.
The points on a section of an exam is given by the function f (x) , where x is the number of questions answered correctly in that section. If f (12) = 18 , then a test-taker receives 18 points for answering _____ questions in the section correctly.
Answer:
The answer is "12"
Step-by-step explanation:
Let f(x) be the function, where x specified in a certain section by the series of queries that have been addressed also as function.
[tex]\to f(12)=18[/tex] it implies, that even a test the person gets 18 points to packed up x queries. Its right series of issues were also:
[tex]\to f(x) = f(12)[/tex]
Therefore x = 12, The correct number of questions in the segment.
The field inside a running track is made up of a rectangle 84.39m (meters) long and 73m (meters) wide, together with a half-circle at each end. The running lanes are 9.76m (meters) wide all the way around. Question: What is the area of the running track that goes around the field? Explain or show your reasoning.
Answer:
3886.53 [tex]m^{2}[/tex]
Step-by-step explanation:
The running track consist of two semicircles and a rectangle.
So that;
Diameter of the semicircles = width of the rectangle = 73 m
radius = [tex]\frac{diameter}{2}[/tex]
= [tex]\frac{73}{2}[/tex]
= 36.5 m
But the two semicircles form a circle, so that;
Circumference of a circle = 2[tex]\pi[/tex]r
Circumference of the circle formed by the semicircles = 2 x [tex]\frac{22}{7}[/tex] x 36.5
= 229.43 m
Thus,
length of the running track = circumference of the circle formed + length of the two sides of the rectangle
= 229.43 + 84.39 + 84.39
= 398.21 m
The length of the running track is 398.21 m.
Therefore;
Area of the running track = length x width
= 398.21 x 9.76
= 3886.5296
The area of the running track is 3886.53 [tex]m^{2}[/tex].

Step-by-step explanation:
Putting a variable next to the coefficient is the same thing as multiplying. You always put the number before the letter.
Hope that helps and have a great day!
The product of p and 6 is written as 6p.
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
The expression as;
'The product of a number p and six'
Now, The multiplication of two number is written with sign ( × ).
Thus, The product of a number p and six is written as;
⇒ p × 6
⇒ 6p

Ticket prices for Students ($3), Adults ($7), Children under 12 ($2) A School band performs a concert for a crowd of 600 people. The revenue for the concert is $3150. There are 150 more adults at the concert than students. How many of each type of ticket are sold?
Answer:
280 adult tickets
130 student tickets
190 children tickets
were sold at the concert
Step-by-step explanation:
Let the number of students be s , adults a and children c
Total 600;
Thus;
a + s + c = 600 •••••••(i)
let us look at revenue
Revenue = number * ticket price
For adults; a * 7 = $7a
For students ; s * $3 = $3s
For children; c * $2 = $2c
Total is 3150
thus;
7a + 3s + 2c = 3150 ••••••••(ii)
150 more adults than students;
a = s + 150 ••••••(iii)
Substitute iii into ii and i
into ii
7(s + 150) + 3s + 2c = 3150
7s + 1050 + 3s + 2c = 3150
9c + 3s = 3150-1050
9c + 3s = 2,100 •••••••(x)
Substitute into i
a + s + c = 600
s + 150 + s + c = 600
2s + c = 600 - 150
2s + c = 450
c = 450 - 2s ••••••(xx)
Now substitute xx into x
9(450-2s) + 3s = 2100
= 4050-18s + 3s = 2100
4050-2100 = 18s - 3s
15s = 1950
s = 1950/15
s = 130
c = 450 -2s
c = 450 - 2(130)
c = 450 - 260
c = 190
a = 150 + s
a = 150 + 130
a = 280
