First, you have to find the slope.
As x increases by 3, y increases by 6 so the slope is rise/run so it would be 6/3 and simplify so it’s gonna be 2.
b of the y=ax+b is y-int so it’s a y value when x is 0 so in this case, 6.
B: y=-2x+8
First, you have to find the slope.
As x increases by 2, y decreases by 4 so the slope would be -4/2 and simplify so it’s gonna be -2.
b is equal to the y-value when x is 0 so in this case, 8.
C: y=3x+4
First, you have to find the slope.
As x increases by 2, y increase by 6 so the slope would be 6/2 and simplify so it’s gonna be 3.
When u solve for b, first, at this point, you have the equation y=3x+b so you’re gonna plug in random point into it so for ex, 2 for x and 10 for y(as it shows on table) and you can get 4.
D: y=-1/2x+6
First, you have to find the slope.
As x increases by 4, y decreases by 2 so the slope would be -2/4 and simplify so it’s gonna be -1/2.
When u solve for b, first, at this point, you have the equation y=-1/2x+b so you’re gonna plug in random point into it so for ex, 8 for x and 2 for y(as it shows on table) and you can get 6.
82. If AB has endpoint A (2,13) and midpoint (10, -1) then
give the coordinate of B.
Answers
Answer:
3
Step-by-step explanation:
The required coordinates of point B are (18, -15) where AB has endpoint A (2,13) and midpoint (10, -1).
What is the midpoint?The midpoint formula states that the coordinates of the midpoint of a line segment with endpoints (x₁, y₁) and (x₂, y₂) are given by the formula (x₁ + x₂)/2, (y₁ + y₂)/2.
As per the question, we are given that AB has endpoint A (2,13) and midpoint (10, -1)
We can use these coordinates to find the coordinates of point B, which is the midpoint of line segment AB.
Let the coordinates of B would be (x, y)
Substituting the coordinates of points A into the midpoint formula gives us :
10 = (x+2)/2 ; -1 = (y+13)/2
20 = x +2 ; -2 = y + 13
x = 18 ; y = -15
Therefore, the required coordinates of point B are (18, -15).

Step-by-step explanation:
The transformation ...
g(x) = f(x -h) +k
translates the graph of f(x) h units to the right and k units up. Here, the cube root function is translated 4 units right and 1 unit down, so h=4 and k=-1. Putting those into your equation gives ...

The slope of the given line can be found from the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (4 -1)/(3 -2) = 3/1 = 3
The slope of the perpendicular line is the opposite reciprocal of this:
perpendicular slope = -1/m = -1/3

Convert 5700 milligrams into pounds. Round your answer to the nearest hundredth.
Answers
The value of the 5,700 milligrams in pounds is approximately 0.01 lb
What is a unit of measurement?A unit of measurement is a specified magnitude of a quantity that is accepted and adopted by convention or backed by law, and used as a measurement standard.
In other to successfully convert a quantity in one unit to another unit, both units (initial and destination unit) should refer to the same characteristics of the object being measured.
Once both units are confirmed to refer to the same quantity, conversion factors are used to multiply the quantity in the first unit in order to express it in the other unit.
The given parameters are;
The quantity to be converted to pounds = 5,700 milligrams
The factor of conversion is 1,000 mg ≈ [tex]2.205 \times 10^{-6}[/tex] lb
Therefore;
[tex]5,700\: mg = 5,700 \times 2.205 \times 10^(-3) ≈ 0.0126[/tex]
Therefore, to the nearest hundredth, we have;
5,700 mg ≈ 0.01 lb
