You have explored how to multiply two integers when one is positive and the other is negative. Is the product of a positive integers and a negative integer always is negative?
Can you explain and give one example pls
Answer: Yes the product of a negative and positive integer will be a negative because multiplying with negatives have rules and this is a rule that’ll be true for any number. For example 7 times -2 is -14 where as -7 times -2 would be 14 and 7 times 2 would be 14
Step-by-step explanation:
A time line is a useful way to represent important dates and events throughout history. It's common to divide a historical time line into events that occurred either BC (to the left of zero) or AD (to the right of zero). The year you're living in right now takes place in AD. BC AD 0 When performing mathematical operations involving dates, we can think of a historical time line as a number line. On the number line, the years increase from left to right. If zero represents the origin, the years to the right of zero are considered positive numbers and the years to the left of zero are considered negative numbers. Using this analogy, here are some events that might appear on a historical number line:
Event Historical Time Line Number Line
(The first ancient games take place in Olympia, Greece. 776 BC -776)
(Construction begins on the Great Wall of China. 221 )
(BC -221 World War I begins in central Europe. AD 1914 1,914 (or 1914)
Use these ideas about time lines and number lines to answer the questions that follow.
Part A The year in which the US Civil War ended was 25 percent later than the year Christopher Columbus set sail from Spain. If c represents the year Columbus set sail, we can write the year the Civil War ended as C +0.25c.

Put these fractions in order from greatest to least:3/4 ,3/5 ,2/3 .
Answer:
3/4, 2/3, 3/5
Step-by-step explanation:
3/4 = 0.75
3/5 = 0.6
2/3 = 0.666...
0.75 > 0.666... > 0.6
Therefore, the fractions from greatest to least are:
3/4, 2/3, 3/5

Write the phrase "9 increased by a number x" as an algebraic expression
Answer:
9+x
Step-by-step explanation:
To write 9 increased by a number x, you need to know that when it says "increased by" it means adding.
So it is saying 9 is being added by x, or 9+x as an algebraic expression.
The phrase "9 increased by a number x" as an algebraic expression would be; 9+x
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
We need to write the given phrase "9 increased by a number x" as an algebraic expression
Let the unknown number = x
To write 9 increased by a number x, we need to know that when it says "increased by" it means adding.
So it is saying 9 is being added by x, then
We can write it 9+x as an algebraic expression.

Answer:
The y-intercept in coordinate form is (0, 2.9), which the y-intercept represents the pickup fee which is $2.90 before any mileage
Step-by-step explanation:
Hello, I do apologize that no one responded for two hours.
1 - Understanding what it means to be a y-intercept
When mathematics presents the "y-intercept" its the unimaginative way of saying "Where the equation crosses the y-axis"
Looking at a graph we can deduce that, the y axis in traditional graphs is always at the x value of 0.
What can this mean for this situation?
We want to find out how much each person with 0 miles or no miles driven.
This will be our pickup fee alone
How can we do this?
Theres multiple ways, however the way I like is to set an equation to zero.
2 - Slope Intercept Form
We need to get it into the slope-intercept form using data given to us to use as our equation.
For reference the slope-intercept form is
y = mx + b
y = y value
m = slope
x = x value
b = y - intercept
2.1 - Find the slope
for y = mx + b we'll need to find our slope, m, and to do so we use the following formula
[tex]slope = m = \frac{\triangle y}{\triangle x} = \frac{change~in~y}{chnage~in~x} = \frac{y_2 ~ - ~ y_1}{x_2 ~ - ~ x_1}[/tex]
To do this we need to assign x values and y values.
Our total cost is our y value, because its a total, and our variable is x which will be our miles.
(x value is always the variable, and our y value is always the totals)
So now looking at the data;
Gus;
$12.00 for a 6.5-mile journey
Tony;
$15.50 for a 9-mile journey
We can deduce at 6.5 miles we'll pay $12, and at 9 miles we'll pay $15.50
Because 6.5 is less than 9 our x1 and y1 will be deduced from that, and with that in mind, let's solve that equation.
POINT → (x, y)
(6.5, 12)
(9, 15.50)
[tex]\frac{y_2 ~ - ~ y_1}{x_2 ~ - ~ x_1} = \frac{15.50 ~ - ~ 12.00}{9 ~ - ~ 6.5} = \frac{3.5}{2.5} = 1.4[/tex]
Our slope is 7/5, so therefore,
y = mx + b
=
y = 1.4x + b
2.2 - Plug and chug to find our y-intercept, b.
We'll need to plug in a point into the unfinished equation to solve for b
y = 7/5x + b
In this instance let's use (6.5, 12)
(x, y)
12 = 1.4(6.5) + b
12 = 9.1 + b
-9.1 -9.1
2.9 = b
Lets plug that in to our y = mx + b
y = 1.4x + b
↓
y = 1.4x + 2.9
And would you look at that, just by setting up the equation we now know our y-intercept, now if you recall from earlier one of my notes said this:
POINT → (x, y)
This is the same thing as coordinate form I'm assuming, and as a result, we have all the information we need to answer the problem.
3 - Putting it together to answer the problem
POINT → (x, y)
=
Coordinate Form:
=
(x, y)
Now remembering what I said earlier, the y-axis, is always on x = 0
So our y-intercept in coordinate form is;
(0, 2.9)
This means;
The pickup fee is $2.90 which excludes any mileage.
See the answer for it put together
Hope this helps :)
