Write the equation of the line that passed through the points (-1,6) and (5,0)
Answer: y = -1x + 5
Step-by-step explanation:
1. Plug the coordinates into the slope formula (y2 - y1)/ (x2 - x1)
(0 - 6)/ (5 -(-1))
2. Solve for slope
-6/6
= -1
3. Plug the first coordinate and slope into the point slope form equation (y - y1) = slope(x - x1) to find the rest of the equation of the line
(y -(-1)) = -1( x - 6)
4. Solve for y
y + 1 = -1x + 6 -----> y = -1x + 5

A section of wall is being framed. A model of the framing work is shown below. Vertical and parallel lines c, d, and e are cut by diagonal transversal b. The uppercase right angle formed by the intersection of lines b and c is angle A. The uppercase left angle formed by the intersection of lines d and b is 125 degrees. Which best describes the relationship between the 125° angle and angle A? They are same side interior angles. Angle A measures 55°. They are alternate interior angles. Angle A measures 125°. They are vertical angles. Angle A measures 125°. They are corresponding angles. Angle A measures 55°.
Answer:
a. They are same side interior angles. Angle A measures 55°.
Step-by-step explanation:
They are the same side interior angles. Angle A measures 55°.
Are all interior angles 180?If you think about it, you'll see that when you add any of the interior angles of a triangle to its neighboring exterior angle, you always get 180 degrees a straight line.
What are interior angles for example?Interior angles are those that lie inside a polygon. For example, a triangle has 3 interior angles. The other way to define interior angles is "angles enclosed in the interior region of two parallel lines when intersected by a transversal are known as interior angles".

I need help with this , Geometry
Answer: 19.42
Step-by-step explanation:
To find the distance, we need to use the distance formula.
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
With the given points, we can plug them in and solve.
[tex]d=\sqrt{(7-3)^2+(-11-8)^2}[/tex] [parenthesis]
[tex]d=\sqrt{(4)^2+(-19)^2}[/tex] [exponent]
[tex]d=\sqrt{16+361}[/tex] [add]
[tex]d=\sqrt{377}[/tex] [square root]
[tex]d=19.42[/tex]
Now, we know the distance is 19.42.

what is 149,597,870 in scientific notation
Answer:
1.4959787 × 10^8
Step-by-step explanation:
Calculating scientific notation for a positive integer is simple, as it always follows this notation: a x 10^b.
Follow the steps below to see how 149,597,870 is written in scientific notation.
Step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 149,597,870
New Number: 1.49597870
Step 2
Now, to find b, count how many places to the right of the decimal.
New Number: 1 . 4 9 5 9 7 8 7 0
Decimal Count: 1 2 3 4 5 6 7 8
There are 8 places to the right of the decimal place.
Step 3
Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10^b
a = 1.4959787 (Please notice any zeroes on the end have been removed)
b = 8
Now the whole thing:
1.4959787 x 10^8
Step 4
Check your work:
10^8 = 100,000,000 x 1.4959787 = 149,597,870

If 2x - 3 = 5x + 6, what is the value of 4x
Steps to solve:
2x - 3 = 5x + 6
~Add 3 to both sides
2x = 5x + 9
~Subtract 5x to both sides
-x = 9
~Divide -1 to both sides
x = -3
Solve for 4x using x = -3
4(-3) = -12
Therefore, the answer is x = -12

Given a point P(8,1) on segment AB with A(-2,3), find the coordinates of B if ap/ab=2/3. The answer should be entered in the form (x,y) without any spaces between characters
Answer:
The coordinates of point B are (23,-2)
Step-by-step explanation:
Mathematically, what this question is telling us is that the point P divides the segment AB in the ratio 2:3
We are now tasked with finding the coordinates of point B
For point P to have divided the segment in that particular ratio, then, internal division formula would have been used.
Mathematically, the internal division formula is given as;
(x,y) = (mx2 + nx1)/(m + n) , (my2 + ny1)/(m + n)
In this particular question case;
(x,y) are coordinates of p = (8,1)
x = 8 , y = 1
m = 2 , n = 3
x1 = -2 , y1 = 3
x2 = x , y2 = y ( coordinates of point B)
So let’s make the substitution;
(8,1) = 2x + 3(-2)/2+3) , 2(y) + 3(3)/(2+3)
(8,1) = (2x-6)/5 , (2y + 9)/5
So therefore; let’s equate
(2x-6)/5 = 8
and 2y+ 9/5 = 1
2x-6/5 = 8
2x -6 = 8*5
2x -6 = 40
2x = 40 + 6
2x = 46
x = 46/2
x = 23
(2y + 9)/5 = 1
2y + 9 = 5 * 1
2y + 9 = 5
2y = 5-9
2y = -4
y = -4/2
y = -2
So the coordinates of point B are (23,-2)

What does this mean?
Answer:
f(x) = |x| represents the modulus function or absolute value function. It gives us the distance between any point and the origin. Since distance can never be negative so we always consider its positive value only. You can simply multiply the given value with ‘-1’(if the given value is negative).
