why is the equation y-y1=m(x-x1) called the point-slope form?
Answer:
The equation of the line with slope m = 2 and passing through the point (1, 1) will be:
[tex]y = 2x[/tex]
Step-by-step explanation:
We know that the point-slope form of the line equation is
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where
m is the slope of the line(x₁, y₁) is the pointThe formula [tex]y-y_1=m\left(x-x_1\right)[/tex] is termed as the point-slope form of the line equation because if we know one point on a certain line and the slope of that line, then we can easily get the line equation with this formula and, hence, determine all other points on the line.
For example, if we are given the point (1, 1) and slope m = 2
Then substituting the values m = 2 and the point (1, 2)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y - 2 = 2(x-1)[/tex]
[tex]y - 2 = 2x-2[/tex]
[tex]y = 2x-2+2[/tex]
[tex]y = 2x[/tex]
Therefore, the equation of the line with slope m = 2 and passing through the point (1, 1) will be:
[tex]y = 2x[/tex]

Part 1 out of 2
The equation is (selen)
(select)
Check
not linear
linear
Answer:
Yes, it is a linear equation. This equation is in y=mx+b form, which is a linear equation. To rearrange it into y=mx+b form, you'll just do y= -2x+8
To make a line, you only need two points, so here are two points that fit into the line of y= -2x+8:
(0,8) and (1,6)

Factor the common factor out of each expression.
Answer:
4 (3 - x)
Step-by-step explanation:
Take the common factor 4 out.
[tex]4([/tex]
Then divide the numbers inside the expression with the common factor
[tex]4( \frac{ - 4x}{4} + \frac{12}{4})[/tex]
[tex]4( - x + 3)[/tex]
You can rewrite it as:
[tex]4(3 - x)[/tex]
Hope it helps!
Answer: 4(-x+3)
Step-by-step explanation:
Hii, do you need to factor the expression -4x+12? No problem! (:
Note that both -4x and 12 have something in common. This "something" is known as the greatest common factor, or g.c.f.
The g.c.f. of -4x+12 is 4.
To factor it out, we first need to divide -4x+12 by 4.
-x+3 is what we obtain
Next, we put parentheses around -x+3
(-x+3) is what we obtain
Finally, we put 4 outside the parentheses
4(-x+3)

Bob walks up to a tank of water that can hold 75 gallons. When it is active, a drain empties water from the tank at a constant rate. When Bob first sees the tank, it contains 15 gallons of water. 4 minutes later, the tank contains 12 gallons of water.
A. At what rate is the amount of water in the tank changing? answers: 3/4, -3, -3/4, 3
B. How many more minutes will it take for the tank to drain completely?
C. How many minutes before Bob arrived was the tank completely full?
Answer:
A) -3/4
B) 15 more minutes
C) 80 minutes
Step-by-step explanation:
A. rate of change = -3/4
B. 16 minutes
C. 1 hour 20 minutes
What is slope?The slope is defined as the ratio of the vertical change between two points, the rise, to the horizontal change between the same two points, the run.
Given:
A) At first the tank contain 15 gallons of water.
After 4 minutes the tank contain 12 gallons of water.
So, rate of change
=12-15/4-0
=-3/4
=-3/4
B) now, Let x be the number of minutes will it take for the tank to drain completely.
So,
(3/4 gallons per minute) *x = 12 gallons
x = 12*4/3
x = 16 minutes
C) As, the tank has capacity of 75 gallons.
So, the tank of water is full when there is 10 gallons of water which is 60 gallons more.
Let 'y' be the number of minutes before Bob arrived when the water tank was completely full.
(3/4) (y) = 60
y = 60*4/3
y= 80 minutes
y= 1 hour 20 minutes

Answer:
They are equivalent
Step-by-step explanation:
n would equal the same, and 10 and 5+5 equal the same. Therefore, whatever n is, they will be equal no matter what. Unless you subtract the n from one side and add on the other.

Consider the Parallelogram
If the perimeter of the parallelogram is 60, what is the length of HG?
Answer:
The length of HG = 11 units
Step-by-step explanation:
We know that opposite sides of a parallelogram are equal.
so
EF = GHand
FG = EHGiven that
FG = 2x+5
so
EH = 2x+5
also
EF = 3x-10
so
GH = 3x-10
Given that the Perimeter of a parallelogram = 60
As the perimeter of a parallelogram is the sum of all the sides, so
FG + EH + EF + FH = 60
substituting FG = 2x+5, EH = 2x+5, EF = 3x-10, GH = 3x-10
(2x+5) + (2x+5) + (3x-10) + (3x-10) = 60
remove parenthese
2x+5 + 2x+5 + 3x-10 + 3x-10 = 60
group similar elements
2x + 2x + 3x + 3x + 5 + 5 - 10 - 10 = 60
10x - 10 = 60
10x = 60+10
10x = 70
divide both sides by 10
10x/10 = 70/10
x = 7
Therefore, the value of x = 7
Thus,
The length of HG = 3x-10 = 3(7) - 10 = 21 - 10 = 11 units
Hence,
The length of HG = 11 units

Simplify FULLY 6:1.2 *
Answer:
after full simplification u will get your ratio as
5:1
The fully simplified form of the ratio 6:1.2 is 5:1.
To simplify the ratio 6:1.2, we can divide both parts of the ratio by their greatest common divisor (GCD) to obtain the simplest form.
First, let's determine the GCD of 6 and 1.2. The GCD of 6 and 1.2 is 0.6 since 0.6 is the largest number that divides both 6 and 1.2 evenly.
Next, divide both parts of the ratio by 0.6:
6 ÷ 0.6 = 10
1.2 ÷ 0.6 = 2
Thus, the simplified ratio is 10:2.
However, we can further simplify the ratio by dividing both parts by their GCD, which is 2:
10 ÷ 2 = 5
2 ÷ 2 = 1
Therefore, the fully simplified form of the ratio 6:1.2 is 5:1.
This means that for every 5 units of the first quantity, there is 1 unit of the second quantity. Simplifying ratios allows for easier comparison and interpretation of the relationship between the two quantities.
