Answer:
2 19/21, 61/21
Step-by-step explanation:
First, lets make the denimonators, "3 and 7" common. 3 and 7 are prime numbers, so the common denonminator is "21".
For 7/3, multiply by "7/7" and for 4/7 multiply by "3/3".
49/21 + 12/21
Add.
61/21
61 is a prime number so this answer will be your final answer.
(unless you have to put it as a mixed number which would be 2 19/21)
If ΔABC ≅ ΔDEF, what is the length of AB?
Answer:
AB=24ft
Step-by-step explanation:

AB=3(6)+6
AB=18 + 6
AB=24
Which of the following values of x solves 3(x−6)=18?
Answer: X=12
Step-by-step explanation: 3(x-6)=18 becomes 3x-18=18 which is 3x=36 because you add 18 to both sides. Then you simplify 36/3 which is 12
Answer:
x=12
Step-by-step explanation:
3(x-6) = 18 - distrubute ( you are solving for x )
3x - 18 = 18 - add 18 to both sides
3x = 36 - divide
x =12
is a relation that is also a function.
{(1,6), (1,7), (7, 8), (8, 9)}
{(2,3), (3, 2), (2, 4), (4, 2)}
{(0, 1), (0, 2), (0, 3), (0,4)}
|{(1, 1), (3, 2), (6,3), (8,4)}
Answer:
The relation {(1, 1), (3, 2), (6,3), (8,4)} is also a function ⇒ D
Step-by-step explanation:
The relation formed from a set of ordered pairs could be a function if every x-coordinate has only one y-coordinate corresponding to it
Examples:
The relation {(1, 3), (-2, 5), (1, -2)} is not a function because x = 1 has two values of y 3 and -2The relation {(2, -3), (-2, 0), (1, 5)} is a function because x = 2 has only y = -3, x = -2 has only y = 0, and x = 1 has only y = 5Let us check all the relation to find which one is a function
∵ The relation is {(1, 6), (1, 7), (7, 8), (8, 9)}
∵ At x = 1, y = 6 and 7
→ x has two values of y
∴ The relation is not a function
∵ The relation is {(2, 3), (3, 2), (2, 4), (4, 2)}
∵ At x = 2, y = 3 and 4
→ x has two values of y
∴ The relation is not a function
∵ The relation is {(0, 1), (0, 2), (0, 3), (0,4)}
∵ At x = 0, y = 1, 2, 3, and 4
→ x has four values of y
∴ The relation is not a function
∵ The relation is {(1, 1), (3, 2), (6,3), (8,4)}
∵ At x = 1, y = 1
∵ At x = 3, y = 2
∵ At x = 6, y = 3
∵ At x = 8, y = 4
→ Every x has only one value of y
∴ The relation is a function
∴The relation {(1, 1), (3, 2), (6,3), (8,4)} is a function

Which statement or statements accurately describe a good way to avoid excessive service fees?
1. Try to deposit money in large batches rather than in small amounts.
II. Try to limit the number of withdrawals you make from out-of-network ATMs.
III. Try to avoid using your debit card online.
a. I and II
b. ll only
c. Ill only
d. I and III
Answer:
b. ll only
Explanation:
Remember, service fees often refer to an amount deducted to pay for the cost of providing particular services, such as ATM service charges, etc.
We can this conclusion because if one decides to deposit money in large batches rather than in small amounts; they will be directly subjecting themselves to excessive charges. Consider, most financial institutions often charge higher fees for larger deposits.
Also, if one decides to avoid using your debit card online they will tend to spend more using traditional cash methods which require increasing the number of one's ATM withdrawal.
However, by trying to limit the number of withdrawals you make from out-of-network ATMs, one saves him or herself of excessive service fees.
Over the past 6 seasons one baseball players average is for 0.238 0.289 0.263 0.302 0.285 and 0.319. Second player batting averages were 0.259 0.348 0.334 0.278 0.311 and 0.174 what are the range and mean of each players batting averages use your results take a player players batting skills
Answer:
First player
Range = 0.081
Mean = 0.283
Second player
range = 0.174
mean = 0.284
Step-by-step explanation:
Mathematically, range is highest value - lowest value while mean refers to the average ( sum of values/count of values)
For first player
Range = (0.319 - 0.238) = 0.081
Mean = (0.238 + 0.289 + 0.263 + 0.302 + 0.285 + 0.319)/6 = 0.283
For the second player;
Range = 0.348 - 0.174 = 0.174
mean = (0.259 + 0.348 + 0.334 + 0.278 + 0.311 + 0.174)/6 = 1.704/6 = 0.284
Point Slope Form : y - y1 = m(x- x1) Write the equation of the line described that passes through (-8,-5), parallel to y = -3x + 9
Answer:
y + 5 = -3(x + 8)
General Formulas and Concepts:
Point-Slope Form: y - y₁ = m(x - x₁)

Step 1: Define
Given (Parallel Line): y = -3x + 9
Point (-8, -5)
Step 2: Find variables
Slope m of parallel lines = -3
Step 3: Find parallel line equation
y₁ = -5

What is Graph?The graph is simply a structured representation of the data. It aids in our comprehension of the data. The numerical information gathered through observation is referred to as data.
In a line graph, the information or data is represented as a series of markers, or dots, and is then connected to one another by a straight line.
Usually, data that varies over time is represented with a line graph.
Given:
As, slope for printer A= 30-2/2-0
= 30/2 = 15 pages per minute.
So, the rate of Printer A is 15 pages per minute.
Thus,
The rate for Printer B is greater than the rate for Printer A because the rate of 25 pages per minute is greater than the rate of 15 pages per minute for Printer A.

Gina tracks the low temperatures for a city over six days. Identify the days colder than-1.75°F. Monday Tuesday Wednesday Thursday Friday -2.5°F -1.9°F 0°F -1.5°F 0.5°F
Answer:
Monday
Tuesday
Step-by-step explanation:
Given the temperature data:
Mon _____ Tue _____ Wed _____ Thur ___ Fri
-2.5°F ___ - 1.9°F _____ 0°F _____ - 1.5°F _0.5°F
Days colder than - 1.75°F
Days colder than - 1.75°F are days whereby the temperature value is less than - 1.75
Hence,
-2.5°F < - 1.75°F = (Monday)
-1.9°F < - 1.75°F = (Tuesday)
Hence, temperature on Monday and Tuesday is colder than - 1.75°F

6x+2y = -10
Question 3
Answer:
y=-3x-5
Step-by-step explanation:
6x+2y=-10
2y = -6x-10 (you need to isolate the y and so i took 6x and subtracted it from both sides)
y = -6/2x-10/2 ( dont feel like explaining)

What are the slope and the y-intercept of the line shown in the graph?
A. y-intercept = 2 and slope = -3
B. y-intercept = 2 and slope = 3
C. y-intercept = 3 and slope = 2
D. y-intercept = -3 and slope = 2
Answer:
A
Step-by-step explanation:
The y intercept is where the line crosses the Y (vertical) axis. In this case, it happens at y=2
The slope is the rate of change. For every 1 space it moves on the horizontal axis, it moves 3 vertical spaces. It is going down, so it is -3

Answer:
The correct option is;
1, 6, 11, 15
Step-by-step explanation:
The given information are;
The function that defines the terms of the sequence is f(n) = f(n - 1) + 5
Where;
n = The number of the term
For n = 1, we have, f(1) = -4
The first four terms are therefore;
f(2) = f(2 - 1) + 5 = f(1) + 5 = - 4 + 5 = 1
f(3) = f(3 - 1) + 5 = f(2) + 5 = 1 + 5 = 6
f(4) = f(4 - 1) + 5 = f(3) + 5 = 6 + 5 = 11
f(5) = f(5 - 1) + 5 = f(4) + 5 = 11 + 5 = 15
The first four terms are; 1, 6, 11, 15
