What is the slope of the line that passes through the points (-10,8) and (-15,-7)
Answer:
3
Step-by-step explanation:
Use the formula y2-y1/x2-x1
Plug in the values (-7-8)/(-15-(-10))
-15/-5
3
Answer:
slope = m , m = rise / run rise = change in y run = change in x
Step-by-step explanation:
to find change in y just subtract the second y from the first , like thus,
P1=(-10,8) = (X1,Y1)
P2=(-15,-7) = (X2,Y2)
-7-8=-15= change in Y
to find the change in X just subtract the second x from the first, like thus,
-15-(-10) = -15+10 = 5
m= -15/5
m=-3
it's a slope of negative 3... make sense?

A hockey goalie is paid $500 per game, less $45 for each goal he allows to score. Write an algebraic expression that would equal how much he gets paid in a game
Answer:
x=500+45y
Step-by-step explanation:
From the information given, the algebraic expression that would equal how much he gets paid in a game would be the amount that the hockey golie is paid per game minus the result of multiplying $45 for the number of goals he allows to score. According to this, the expression is:
x=500+45y, where x is the amount the hockey goalie gets paid in a game and y is the number of goals he allows to score.

Answer: SEE EXPLANATION!
Step-by-step explanation:
Population Parameters versus Sample Statistics
A parameter is a value that describes a characteristic of an entire population, such as the population mean. ... A statistic is a characteristic of a sample. If you collect a sample and calculate the mean and standard deviation, these are sample statistics.
The difference between Population characteristic and Sample statistic is discussed below.
What is Statistic?Statistics is a branch of applied mathematics that allows us to collect, describe and analyze the given set of data in order to make inference of conclusions on the given data set.
Given are two terms as population characteristic and a sample statistic.
Population characteristic refers to the characterization of various types of populations within a social or geographic group, with emphasis on demography, health status, and socio-economic factors. There are various characteristics of a population such as population size and density, populace spatial dissemination, age structures, birth rate or Natality and mortality rate.
Sample statistic represents the calculation that you measure from a subset of a larger group (the population).There are 5 types of sampling - Systematic, random, convenience, cluster and stratified.
Therefore, the difference between Population characteristic and Sample statistic is discussed above.

A store has 5 rings and 9 bracelets for sale. If all 14 items sell, how much money will the store take in? Choose the correct answer and explanation. Bracelets cost $88. Rings cost $125. A. $1,417 9 × $88 = $792; 5 × $125 = $625; $792 + $625 = $1,417 B. $1,427 9 × $88 = $802; 5 × $125 = $625; $802 + $625 = $1,427 C. $1,565 9 × $125 = $1,125; 5 × $88 = $440; $1,125 + $440 = $1,565 D. $2,982 5 + 9 = 14; $88 + $125 = $213; 14 × $213 = $2,982
Answer:
The correct answer is A. $1,417 9 × $88 = $792; 5 × $125 = $625; $792 + $625 = $1,417.
Step-by-step explanation:
From the question,
A store has 5 rings and 9 bracelets for sale. If all 14 items sell, the amount of money the store will take in can be determined by summing up the total cost of the rings and the total cost of the bracelets.
First, we will determine the total cost of the rings
From the question, a ring cost $125
∴ 5 rings will cost 5 × $125
5 × $125 = $625
Hence, the total cost of the rings is $625
For the bracelets
From the question, a bracelet cost $88
∴ 9 bracelets will cost 9 × $88
9 × $88 = $792
Hence, the total cost of the bracelets is $792
The amount the store will take in will be $625 + $792 = $1417
Hence, if all 14 items sell, the amount of money the store will take in will be $1417.
The correct answer is A. $1,417 9 × $88 = $792; 5 × $125 = $625; $792 + $625 = $1,417
Answer:
The correct answer is A. $1,417 9 × $88 = $792; 5 × $125 = $625; $792 + $625 = $1,417.

Coconuts were on sale, 4 for $4.44. Pineapples were on sale, 3 for $3,63. Which
of the following is true?
ОА.
1/6
Coconuts are 10¢ less each than pineapples,
Coconuts are 10¢ more each than pineapples,
B.
OC. Coconuts are each $1.21.
OD. Pineapples are each $1.11.
Answer:
The answer is Coconuts are 10 cents less than the pineapples.
Step-by-step explanation:
You had to find what each of them cost which was $1.11 for each coconuts and the pineapples were $1.21 each. Then you had to subtract to find the difference which was 10 cents. So since the pineapples were more, the answer was the coconuts were 10 cents less than the pineapples.
Coconuts: $4.44 ÷ 4 = $1.11 each Pineapple: $3.63 ÷ 3 = $1.21 each
1.21 - 1.11 = 10 cents

A rectangular playground is to be fenced off and divided in two by another fence parallel to one side of the playground. Six hundred feet of fencing is used. Find the dimensions of the playground that maximize the total enclosed area. What is the maximum area?
Answer:
the smallest dimension = 100 ft
the largest dimension = 150 ft
Maximum Area = 15000 ft²
Step-by-step explanation:
let x represent length of one side and L represent length of adjacent side
so from the question
3x + 2L = 600
2L = 600 - 3x
L = (600 - 3x)/2
L = (600/2) - (3x/2)
L = 300 - (3x/2)
now Area of rectangle = L × x
Area = (300 - (3x/2)) × x
Area = 300x - 3x²/2
now we differentiate with respect to x and equate to 0 in other to find critical point
dA/dx ⇒ 300x/x - 3x²/x = 0
300 - 3x = 0
3x = 300
x = 300/3
x = 100
so we input value of x into our previous equation
Area = 300x - 3x²/2
= 300(100) - (3(100)²)/2
= 30000 - 15000
Area = 15000
also we input value of x in L = 300 - (3x/2)
L = 300 - (3(100))/2)
L = 300 - 150
L = 150
Therefore
the smallest dimension = 100 ft
the largest dimension = 150 ft
Maximum Area = 15000 ft²
