Rules & Examples of Integers multiplication.
Step-by-step explanation:
A rational number is a number that can be expressed as a fraction of integers (positive or negative numbers). Every integer is a rational number.
They are multiplied based on following rules :
Positive (+) x Positive (+) = Positive (+) , +2 x +2 = 4 Positive (+) x Negative (-) = Negative (-) , +2 x -2 = -4 Negative (-) x Positive (+) = Negative (-) , -2 x +2 = -4 Negative (-) x Negative (-) = Positive (+) , -2 x -2 = 4Answer:

Answer:
The tides change as the three interact.
Step-by-step explanation:
When the sun, moon, and Earth are in alignment (at the time of the new or full moon), the solar tide has an additive effect on the lunar tide, creating extra-high high tides, and very low, low tides—both commonly called spring tides.
What is the value of x in the equation 3(x + 10) = 4(x − 2)?
Answer:
3x+30=4x-8
-x=-38
x=38
Final Answer: [tex]x = 38[/tex]
Steps/Reasons/Explanation:
Question: What is the value of x in the equation [tex]3(x + 10) = 4(x - 2)[/tex]?
Step 1: Expand.
[tex]3x + 30 = 4x - 8[/tex]
Step 2: Subtract [tex]3x[/tex] from both sides.
[tex]30 = 4x - 8 - 3x[/tex]
Step 3: Simplify [tex]4x - 8 - 3x[/tex] to [tex]x - 8[/tex].
[tex]30 = x - 8[/tex]
Step 4: Add [tex]8[/tex] to both sides.
[tex]30 + 8 = x[/tex]
Step 5: Simplify [tex]30 + 8[/tex] to [tex]38[/tex].
[tex]38 = x[/tex]
Step 6: Switch sides.
[tex]x = 38[/tex]

Answer: 3
Step-by-step explanation:
1. 2²=4
2. 4*5=20
3. 180/20=9
4. √9=3
Hope this helped :)
Answer:
x = 3
Choice 2
Step-by-step explanation:
180 = 2^2 * x^2 * 5
180 = 20x^2
9 = x^2
x = 3
Checking:
180 = 2^2 * 8^2 * 5
180 = 4 * 9 * 5
180 = 36 * 5
180 = 180

Estimate the value of y when x =2.5
Both of them
Step-by-step explanation:
[tex]y = {2.5}^{2} - 2(2.5) - 3 [/tex]
-1.75
Here we need to learn how to read a graph.
In a normal graph we have the inputs (the values of x) in the horizontal axis and the outputs in the vertical axis.
Here we want to see what is the value of y for the blue graph when x = 2.5
We will find y = -1.5
(the blue graph is the one that corresponds to: y = x^2 - 2x - 3)
To find this:
The first thing we need to do is find x = 2.5 in the horizontal axis.
Now that we found it, we need to draw a vertical line, and see at which point of the blue graph this vertical line intersects the curve. At that point we draw an horizontal line that intercepts the vertical axis.
At that point we have the y-value
You can see an example of this, a good estimation by only looking at the graph is y = -1.5
For the other point, the value of x when y = 1.
We do exactly the same thing but in the inverse order, we first find y = 1
Then we draw an horizontal line that intercepts the graph
Then we draw a vertical line that intercepts the x-axis and we find the value.
We can see that for y = 1 we have x = 3.2 aprox.

Find the equation of the line
Use exact numbers
y=___x+____
y = -1.5x + 3 is the equation of the line
How to find the equation of the line?
The general form of the equation of a line is y = mx + b,
where m is the slope of the line and b is the y-intercept (the point at which the line crosses the y-axis).
slope (m) = (y2-y1)/(x2-x1)
From the graph: x1 = 0, y1 =3 and x2 = 2, y2 = 0
m = (0-3)/(2-0) = -3/2 = -1.5
From the graph: b = 3
Therefore, the equation of the line is y = -1.5x + 3

Answer:
(7 , 5)
Step-by-step explanation:
Add all the x-axis then divide by 3
7 + 3 + 11 = 21
21/3 = 7
Add all the y-axis then divide by 3
9 + 3 + 3 = 15
15/3 = 5
So answer will be (7,5)
The coordinates of the centroid of triangle ABC.
(x, y)
Where,
x = Sum all the x-coordinates of the vertices ÷ 3
y = Sum o

A line passes through the point (-2, 4), and its y-intercept is (0,6). What is the equation of the line that is
perpendicular to the first line and passes through the point (5, 4)?
Answer:
y = -x + 9
Step-by-step explanation:
The line that passes through the points (-2,4) and (0,6) has a slope of 1, and a y intercept of 6. The equation to the first line is y = x + 6. and perpendicular lines always have the opposite, reciprocal slope of the other line. So the slope for the second line would be -1. A line with the slope of -1 and a point of (5,4) would contain the points (5,4) , (4,5) , (3,6) , (2,7) , (1,8) , and (0,9) , which is the y intercept for the second line. So the equation for the second line would be y = -x + 9
