Equation of a Straight Line
1.1 Solve 5x+7y-3914 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 5x+7y-3914 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is 3914/7 so this line "cuts" the y axis at y=559.14286
y-intercept = 3914/7 = 559.14286
Calculate the X-Intercept :
When y = 0 the value of x is 3914/5 Our line therefore "cuts" the x axis at x=782.80000
x-intercept = 3914/5 = 782.80000
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 559.143 and for x=2.000, the value of y is 557.714. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 557.714 - 559.143 = -1.429 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = -1.429/2.000 = -0.714
Geometric figure: Straight Line
Slope = -1.429/2.000 = -0.714
x-intercept = 3914/5 = 782.80000
y-intercept = 3914/7 = 559.14286
Step-by-step explanation:
Answer:
y= -5/7x+3914/7
Step-by-step explanation:
Slope form is y=mx+b
5x+7y=3914
7y = -5x+3914 minus the 5x from each side
7y=-5x+3914 divide 7 from each side --> y= -5/7x+3914/7
So, 5x+7y=3914 is in ax+by=c (standard form) the "a" in "ax" can't be negative either.

Evaluate 2-10+8-\left(-2\right)2−10+8−(−2)2, minus, 10, plus, 8, minus, left parenthesis, minus, 2, right parenthesis.
Answer:
Here we want to solve the equation:
"2, minus, 10, plus, 8, minus, left parenthesis, minus, 2, right parenthesis."
This can be written as:
2 - 10 + 8 - (-2)
Remember that we can solve this in any order we want, so let's go from left to right:
So we can solve first:
( 2 - 10) + 8 - (-2)
We know that:
2 - 10 = -8
Then we can replace that in the expression to get:
( 2 - 10) + 8 - (-2) = -8 + 8 -(-2)
Now we can solve:
(-8 + 8) - (-2)
We know that:
-8 + 8 = 0
Replacing that in the equation we get:
(-8 + 8) - (-2) = 0 - (-2) = -(-2)
And now we can remember the rule of the signs:
(+)*(+) = (+)
(-)*(-) = (+)
(-)*(+) = (-)
(+)*(-) = (-)
Then:
-(-2) = (-1)*(-2) = +(1)*(2) = 2
The solution of the expression is 2.
Answer:
The answer is 2

What is the equation of a line parallel to the y axis and passing through the point (2,1)?
Answer:
x = 2
Step-by-step explanation:
lines parallel to the y-axis are always vertical and begin with 'x ='
Answer:
x=2
Step-by-step explanation:
Hi there!
A line parallel to the y-axis would make it a vertical line. Vertical lines have the equation x=d, where d is the x-intercept (the value of x when y=0).
We also need to know that every point a vertical line passes through has the same x-coordinate. Therefore, because this line passes through the point (2,1), we know that the x-intercept is (2,0).
Therefore, the equation of the line would be x=2.

Step-by-step explanation:
A relation is a function if and only if there is exactly one output for each input. Any relation map with two or more arrows coming from any input is NOT a function.
Here, the input "2" has two outputs, 4 and 5, so this map does not show a functional relationship.

The graph of the absolute value function can be seen at the end of the answer.
How to graph the absolute value function?For an absolute value function:
y = |x - a| + b
We need to start by graphing the vertex, which is the point (a, b).
Then, depending on the slope, we graph the arms.
In our case:
y = |x - 4| + 2
The slope is 1, so both the arms will open upwards with a 45° angle, and we can see that the vertex is (4, 2).

Recall that two angles are complementary if the sum of their measures is 90. Find the measures of two complementary angles if one angle is 15 degree more than two times the other angle.
Answer: 25° and 65°
Step-by-step explanation:
Let the smaller angle of the complementary angle be represented by x.
Since the other angle is 15 degree more than two times the other angle, this will be:
= (2 × x) + 15°
= 2x + 15°.
Then we add both angles together and equate them to 90° and this will be:
x + 2x + 15° = 90°
3x + 15° = 90°
3x = 90° - 15°
3x = 75°
x = 75°/3
x = 25°
Then the other angle will be:
= 2x + 15°
= (2 × 25°) + 15°
= 50° + 15°
= 65°
Therefore, the angles are 25° and 65°.

L = 3/a = 3/8
R = 16/a = 16/8 = 2
\ac/
L V R
/ \
/ b \
where letters have their usual meaning. Comparing 8x² + 19x + 6 to ax² + bx + c,
ac = 8*6 = 48
b = 19
Factors of ac or 48 :-
1 * 48
2 * 24
3 * 16
As the sum of 3 and 16 is 19(or b), our required pair is 3 and 16.
On the left side:
L = 3/a = 3/8
On the right side:
R = 16/a = 16/8 = 2
Therefore, factorized form is (x + 3/8)(x + 2) which can be written as (8x + 3)(x + 2).
How this method works:
Make a X with ac and b on the top and bottom of the X, where ac and b are taken from ax² + bx + c.
On the left side we have d/a and e/a. Basically d and e are those values that we get after solving the whole question.
Step1: find the pair(s) for which sum of factors of ac = b. Here it is 3 and 16.
Step2: put these values in place of d and e.
Step3: solve left anf right of X,
Left = d/a = 3/8
Right = e/a = 16/8 = 2
Step4: whatever you get, put that in (x+?)(x+?) in place of ?.

Answer:
4 white horses.
Step-by-step explanation:
First, you need to find the total of the first set of horses (basically how many total were in the table).
~ 3+2+9+1 = 15
Next we need to find how many horses were white horses out of these 15 horses. In short the proportion would be White Horses/Total Horses.
~ [tex]\frac{3}{15}[/tex] (or [tex]\frac{1}{5}[/tex], simplified)
Now, all we need to do is create the proportion with 20 as the denominator (in this case, 20 will be the total horses, and we just need to find X, or how many horses are expected to be white out of all of those horses). The proportion will look somewhat like this:
~ [tex]\frac{1}{5}[/tex] = [tex]\frac{x}{20}[/tex]
The final step is to multiply across (1x20) then divide that number by the 5 to find X.
~ 20÷5 = 4
Anyways, that means it would be expected to have 4 white horses out of 20 total. Hope this helped ^-^

step and justification of root√3.5
[tex] \large \boxed{ \boxed{ \sqrt{3.5} }}[/tex]
In this case, we are going to use the 'Babylonian method to get the square root of any positive number.We must define an error for the final result.Say, less than 0.01. In other words, we will try to find the value of the square root to at least 1 correct decimal places.
Step 1:
Divide the number (3.5) by 2 to get the first guess for the square root. first guess = 3.5 / 2 = 1.75.Step 2:
Divide 3.5 by the result obtained in stepprevious. d = 3.5 / 1.75 = 2.Roll the arithmetic mean of (d) and the obtained valuein step 1: (2 +1.75) / 2 = 1.875 (newapproach).
Error = new guess - previous value = 1.75 1.875 = 0.125.0.125 0.01. As the error> accuracy, please repeat thist happened one more time.Step 3:
Divide 3.5 by the result obtained in the previous step. d = 3.5 / 1.875 = 1.8666666667.Roll the arithmetic mean of (d) and the value obtained in step 2: (1.8666666667 + 1.875) / 2 =1.8708333334 (new approximation).Error = new guess - previous value = 1.875 -1.8708333334 = 0.00416666660.0041666666 <0.01. Once the error <accuracy, stop the process and use 1.8708333334 as the final value for the square root.Then we can say that the square root of 3.5 is 1.87 with an error less than 0.01 (actually the error is 0.0041666666). This means that the first 2 decimal places are correct. Just for comparison, the returned value using the javascript function Math.sqrt (3.5) 'is 1.8708286933869707.Note: There are other ways to calculate square root. This is just one of them.
