Answer:
Slope: -5
y-Intercept: -1
Step-by-step explanation:
In the equation y = mx + b (its the form of a linear equation) the slope is m and the y-intercept is b. Comparing that to the problem, we can see that m = -5 and b = -1. So, the slope is -5 and the y-intercept is -1.
Answer:
y= -5x -1
y=mx+b
b- is y intercept
m-is slope

Hailey was given a box of assorted chocolates for her birthday. Each night, Hailey treats herself to some chocolates. The number of chocolates remaining in the box tt days after Hailey's birthday can be modeled by the equation C=-4t+24.C=−4t+24. What is the yy-intercept of the equation and what is its interpretation in the context of the problem?
Answer:
y intercept is 24 (i think)
Step-by-step explanation:
-4t is x
+24 is y
Answer:
C=30-5t
Step-by-step explanation:
The y-intercept of the function is 30 which represents the number of chocolates in the original box.
that's the correct answer^^^^
Rachelhasalreadywritten10pages,andsheexpectstowrite1pageforeveryadditionalhourspentwriting.HowmanyhourswillRachelhavetospendwritingthisweekinordertohavewrittenatotalof27pages?
Answer:
17 hours
Step-by-step explanation:
Rachel has already written 10pages, and she expects to write 1page for every additional hour spent writing. How many hours will Rachel have to spend writing this week in order to have written a total of 27pages?
The illustration can be modelled using the equation
y = 10 + 1(x)
y = 10 + x
Where,
y = total number of pages
x = number of hours
10 = pages already written
If y = 27 pages, find x
y = 10 + x
27 = 10 + x
27 - 10 = x
17 = x
x = 17 hours
Rachel have to spend 17 hours writing this week in order to have written a total of 27pages
the sum of the interior angles in a pentagon
Answer:
540°
Step-by-step explanation:
When you have a polygon (shape with 3+ sides), you can split the shape into the lowest number of triangles and use that to calculate the interior angles of the shape. Thus works because triangles have angles that always add up to 180°
A Pentagon can be split into 3 triangles minimum, which means you have 180 + 180 + 180. Or...
180 x 3 = 540

The range of the data:25, 81, 20, 22, 16, 6, 17,15,12, 30, 32, 10, 91, 8, 11, 20 is
Answer:
85
Step-by-step explanation:
The range is defined as the difference between the highest observation and lower observation in a data.
Here,
The Highest observation in this data= 91
The Lowest observation in this data=6
Hence,
Range of the data= Highest observation - Lower observation
=91-6=85

In a triathlon, Kailee swam for 1 hour, biked for 1.75 hours, and ran for 1 hour. Her average biking speed was 2 times her average running speed, and her average running speed was 8 times her average swimming speed. The total distance of the triathlon was 55.5 kilometers. Write an equation and solve it to find Kailee’s average swimming speed in kilometers per hour.
The problem tells you to make a sketch, a table, and equation but I only want an equation please. No answer either.
Answer:
Swimming speed, S = 1.50 km/hr
Step-by-step explanation:
Let Kailee's running speed be R
Let Kailee's biking speed be B
Let Kailee's swimming speed be S
Given the following data;
Time for swimming = 1 hour.
Time for biking = 1.75 hour.
Time for running = 1 hour.
Total distance = 55.5km
Translating the word problem into an algebraic equation, we have;
Biking speed = 2*8S = 16S
Running speed = 8S
We know that the distance covered by an object or body is given by the formula;
[tex] Distance = speed * time[/tex]
Now we would find the distance covered in each activity (biking, running and swimming).
For biking;
[tex] Distance, D_{1} = 1.75*16S [/tex]
Distance, [tex] D_{1} [/tex] = 28S
For running;
[tex] Distance, D_{2} = 1*8S[/tex]
Distance, [tex] D_{2} [/tex] = 8S
For swimming;
[tex] Distance, D_{3} = 1*S[/tex]
Distance, [tex] D_{3} [/tex] = S
The equation for the total distance covered in the triathlon is given by;
Total distance = sum of all distances covered
[tex] Total distance = D_{1} + D_{2} + D_{3} [/tex]
Substituting into the equation, we have;
[tex] 55.5 = 28S + 8S + S[/tex]
[tex] 55.5 = 37S[/tex]
[tex] S = \frac {55.5}{37} [/tex]
S = 1.50 km/hr
Therefore, Kailee’s average swimming speed is 1.50 kilometers per hour.

Find the slope of the line through the following points. (-1, -4) and (-3,4)
A. 1/4
B. -1/4
C. 4
D. -4
Answer:
The answer is C, the slope is 4.
Step-by-step explanation:
Finding slope using two given points is easy. You need to do (y2-y1/x2-x1)
(-1,-4) the -1 is x1 and the -4 is y1. (-3,4) the -3 is x2 and the 4 is y2.
You plug them into the formula giving you
(4-(-4)/ -3-(-1)= 8/-2= 4
The Smith family went out to eat at Applebees. The total for their meal was $58.25. If they want to leave a 20%, how much tip should they give their server?
Answer:
$11.65
Step-by-step explanation:
20% of 58.25, "of" in math means multiplication. So you multiply it.
To get 20% as a fraction you move the decimal 2 places to the left, and it's .2 or .20 so you get this equation:
.20 * 58.25
So your answer is, $11.65.
To find the total of the bill including the tip it would just be
11.65 + 58.25 = 69.90
In ABCD, ZC = ZB, BC = 6 and DB = 9. Find the length of CD.
Answer:
the lenght of CD is 6
Step-by-step explanation:
BC =6 and DB=9 substract DB with BC (9-6=3) it increases by 3 so thats why from BC is 6 and from B to D is 9 bc it increased by 3
How do you reduce a ratio?
How to Simplify a Ratio A : B when A and B are both whole numbers
List the factors of A
List the factors of B
Find the greatest common factor of A and B, GCF(A, B)
Divide A and B each by the GCF
Use the whole number results to rewrite the ratio in simplest form
If the GCF = 1 then the ratio is already in simplest form.
How to Simplify a Ratio A : B when A and B are not whole numbers, in this order
If A or B are mixed numbers convert mixed numbers to improper fractions
If A or B are decimal numbers multiply both values by the same factor of 10 that will eliminate all decimal places
If one value is a fraction and the other a whole number, reduce the fraction to a whole number if you can or turn the whole number into a fraction by giving it a denominator of 1.
If both A and B are fractions and have like denominators, multiply both fractions by the denominator to eliminate it and you are left with two whole numbers
If both A and B are fractions and have unlike denominators, find the LCD(A, B) and rewrite the fractions with the LCD as the denominator. Multiply both fractions by the denominator to eliminate it and you are left with two whole numbers
If both A and B are whole numbers, Find the greatest common factor of A and B, GCF(A, B), and divide A and B each by the GCF
Example: Simplify the ratio 6 : 10
The factors of 6 are: 1, 2, 3, 6
The factors of 10 are: 1, 2, 5, 10
Then the greatest common factor of 6 and 10 is 2
Divide both terms by 2
6 ÷ 2 = 3
10 ÷ 2 = 5
Rewrite the ratio using the results. The simplified ratio is 3 : 5.
6 : 10 = 3 : 5 in simplest form
Answer:
List the factors of A.
List the factors of B.
Find the greatest common factor of A and B, GCF(A, B)
Divide A and B each by the GCF.
Use the whole number results to rewrite the ratio in the simplest form.

Given \sec A=\frac{14}{\sqrt{171}}secA= 171 14 and that angle AA is in Quadrant I, find the exact value of \csc AcscA in simplest radical form using a rational denominator.
Answer:
Step-by-step explanation:
[tex]sec A=\frac{14}{\sqrt{171} } \\cos ~A=\frac{\sqrt{171} }{14} \\sin ~A=\sqrt{1-cos^2A} =\sqrt{1-\frac{171}{196} } =\sqrt{\frac{196-171}{196} } =\sqrt{\frac{25}{96} } =\pm\frac{5}{14} \\csc A=\pm \frac{14}{5}[/tex]
as A is in quadrant 1
[tex]so~csc~A=\frac{14}{5}[/tex]
in quadrant 1 both sin A and csc A are positive.

Foster is centering a photo that is 5 - inches wide on a scrapbook page that is 16 inches wide. How far
2
from each side of the page should he put the picture? Enter your answer as a mixed number.
9514 1404 393
Answer:
5 1/2 inches
Step-by-step explanation:
The page is 16 -5 = 11 inches wider than the photo, so the margin on either side needs to be 11/2 = 5 1/2 inches.
Five more than the product of a number and 9 is 2.
Answer:

Find the EXACT value of sec (-120 degrees)
Well sec(-120) = 1/cos(-120).
We know that cos(-120) = -1/2.
So, 1/(-1/2) = -2.
This means that sec(-120) = -2.
(3 + 4i) + (5 − 2i) (2 points) −2 + 6i 2 − 2i 7 + 3i 8 + 2i
Answer:
8+2i
Step-by-step explanation:
Combine like terms
3+5=8
4i-2i=2i
Answer: 8 + 2i
Step-by-step explanation:
1) Rewrite the two complex numbers in standard form: (3 + 4i) + (5 − 2i) = 3 + 5 + 4i - 2i = 3 + 5 + 2i
2) Add the real parts and the imaginary parts separately: Real parts: 3 + 5 = 8 Imaginary parts: 2i + (-2i) = 0
3) Put the results in standard form: 8 + 0i = 8 + 0i = 8 + 0i = 8 + 0i = 8 + 0i = 8 + 2i
