Answer:
= -1/5
Step-by-step explanation:
To find the slope we use
m = ( y2-y1)/(x2-x1)
= ( -5 - -6)/(-7 - -2)
( -5 +6)/(-7 +2)
1/-5
= -1/5
Answer:
-1/5
Step-by-step explanation:
Y2 - Y1 / X2 - X1
-6 - -5 / -2 - -7
Convert: -6 + 5 / -2 + 7
-1/5

Calculating the Least Common Multiple
3.1 Find the Least Common Multiple
The left denominator is : 16
The right denominator is : 12
Number of times each prime factor
appears in the factorization of:
Prime
Factor Left
Denominator Right
Denominator L.C.M = Max
{Left,Right}
2 4 2 4
3 0 1 1
Product of all
Prime Factors 16 12 48
Least Common Multiple:
48
Calculating Multipliers :
3.2 Calculate multipliers for the two fractions
Denote the Least Common Multiple by L.C.M
Denote the Left Multiplier by Left_M
Denote the Right Multiplier by Right_M
Denote the Left Deniminator by L_Deno
Denote the Right Multiplier by R_Deno
Left_M = L.C.M / L_Deno = 3
Right_M = L.C.M / R_Deno = 4
Making Equivalent Fractions :
3.3 Rewrite the two fractions into equivalent fractions
Two fractions are called equivalent if they have the same numeric value.
For example : 1/2 and 2/4 are equivalent, y/(y+1)2 and (y2+y)/(y+1)3 are equivalent as well.
To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.
L. Mult. • L. Num. 117 • 3
—————————————————— = ———————
L.C.M 48
R. Mult. • R. Num. 47 • 4
—————————————————— = ——————
L.C.M 48
Adding fractions that have a common denominator :
3.4 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
117 • 3 - (47 • 4) 163
—————————————————— = ———
48 48
Final result :
163
——— = 3.39583

A point moves in the plane in the following sequence.
A point moves down 2 units, reflects over the x-axis, moves right 4 units, and then reflects over the y-axis.
Which of the following points follows the sequence and has the same starting and ending point?
A. (2, 3)
B. (–1, 1)
C. (–3, –3)
D. (–2, 1)
Answer:
D
Step-by-step explanation:
The answer is point D(-2,1).
1. If the point D was moved down 2 units, then its coordinates became (-2,-1).
2. If point (-2,-1) was reflected over the x-axis, then its coordinates became (-2,1).
3. If the point (-2,1) was moved 4 units to the right, then its coordinates became (2,1).
4. If point (2,1) was reflected over y-axis, its coordinates became (-2,1).

5) Solve: 2.4p + 6 = 48
Answer:
p = 17.5
Step-by-step explanation:
This is the answer because:
1) First, we have to isolate x
2) To isolate x, first -6 from +6 and 48
+6 - 6 = 0
48 - 6 = 42
Equation: 2.4p = 42
3) Now we are left with 2.4p = 42
4) Next, divide 2.4 from 2.4 and 42
2.4/2.4 = 0
42/2.4 = 17.5
5) We are left with
p = 17.5
Therefore, the answer is p = 17.5

III. Solve the problems below: 42 boys and 63 girls took part in an art competition.(4 pts) Find the ratio of the number of boys to the number of girls (always in the simplest form). Find the ratio of the number of boys to the number of girls to the total number of children (always in the simplest form).
Answer:
Ratio of number of boys to girls= 2:3
Ratio of number of boys to girls to total number of children= 2:3:5
Step-by-step explanation:
42 boys and 63 girls took part in an art competition
The ratio of the number of boys to the number of girls can be calculated as follows
= 42/63
= 2:3
The ratio of the number of boys to girls to total number of children can be calculated as follows
= 42/63/105
= 2:3:5

Moesha and Keyon are mailing invitations for their wedding. They have $50 to spend and each invitation costs $1.25 to mail. The function m=50−1.25w represents the amount of money m Moesha and Keyon have left after mailing w wedding invitations. Find the zero of the function. Describe what this value means in the context of this situation.
Answer:
The zero of the equation is 40
It means the number of wedding invitations they can send based on their budget
Step-by-step explanation:
To determine the zero of the function, we simply set the dependent variable ( m in this case) to zero.
Thus, mathematically;
0 = 50-1.25w
1.25w = 50
w = 50/1.25
w = 40
So what does this mean in the context of the situation?
What it means is that the total number of people they would be able to send the mail to based on their budget is 40
Answer:
The zero of the function is at
40. This represents that after mailing 40 wedding invitations, Moesha and Keyon will $ 0 left.

A smartphone device has a certain cost. A person gets this smartphone and signs up for a monthly wireless plan with a fixed base price plus a charge per GB of data used. Which is the Independent Variable in this scenario? A. The cost of the smartphone device. B. The charge per GB of data used. C. The number of GB data used. D. The total amount they pay for the new device and new phone plan in the first month. Need an answer fast! Due very soon! Don't understand!
Answer:
The independent variable is: "the cost of the smart phone"
Step-by-step explanation:
An independent variable is simply one that doesn't depend on other variables measured in the same sentence.
Now, in the question, we are told that the smart phone device has a fixed cost. This means that the cost doesn't depend on any other variable mentioned in the sentence.
Thus, the independent variable is: "the cost of the smart phone"

A golf course charges $18 to golf 18 holes and $7 for a cart for a no-member.
To become a member you have to pay $560 and $5 for a cart for each round
of 18 holes you golf. How many times would you have to golf 18 holes with a
cart to justify becoming a member?
*
Answer:
at least 81 times. playing 80 times would mean you played exactly what it's worth, 7*80=560, so playing 81 times means you pocket a difference of 7 dollars. if you're going to be playing at least 81 times yearly, go for the membership..
