What’s the equation of the line that passes through the points (7,-4) and (-7,1)
Answers
Answer:
5x +14y = -21
Step-by-step explanation:
One way to write the equation of a line from two points is ...
(y2 -y1)(x -x1) -(x2 -x1)(y -y1) = 0
(1 -(-4))(x -7) -(-7 -7)(y -(-4)) = 0
5(x -7) +14(y +4) = 0
5x +14y -35 +56 = 0
5x +14y = -21 . . . standard form equation of the line

Answer: The Commutative Property of Multiplication
Step-by-step explanation: The commutative property of multiplication states that when two numbers are being multiplied, their order can be changed without affecting the product. In this case, changing the order of 16 and 2, doesn’t matter because they will always be equivalent to each other.

Answer:
1. line b is perpendicular to the other two, which are parallel
2. line a is perpendicular to the other two, which are parallel
Step-by-step explanation:
1. The differences between coordinates (∆x, ∆y) are ...
(-2, 3) -(1, -1) = (-3, 4) . . . line a
(-3, 1) -(1, 4) = (-4, -3) . . . line b
(0, 2) -(3, -2) = (-3, 4) . . . line c
When the (∆x, ∆y) values are identical, the lines are parallel. If the values are swapped, and one differs in sign, the lines are perpendicular.
line b is perpendicular to lines a and b, which are parallel
__
2. When all of the equations are written in standard form, they are ...
4x +y = 7 . . . line ax -4y = 2 . . . line bx -4y = 3 . . . line cAs above, when the x- and y-coefficients are identical, the lines are parallel. If they are swapped and one is negated, the lines are perpendicular.
line a is perpendicular to lines b and c, which are parallel

Find (f-g) (x)
Answers
Answer:
After solving we get [tex]\mathbf{(f-g)(x)=-4x^3+7x^2+5x-8}[/tex]
Option A is correct option.
Step-by-step explanation:
We are given :
[tex]f(x) = 4x^2 +5x -3\\g(x)= 4x^3 - 3x^2 +5[/tex]
We need to find (f-g)(x)
(f-g)(x) is equal to f(x)-g(x)
So, finding (f-g)(x)
[tex](f-g)(x)=f(x)-g(x)\\(f-g)(x)=4x^2+5x-3-(4x^3-3x^2+5)\\(f-g)(x)=4x^2+5x-3-4x^3+3x^2-5\\Combining \ like \ terms:\\(f-g)(x)=-4x^3+3x^2+4x^2+5x-3-5\\(f-g)(x)=-4x^3+7x^2+5x-8[/tex]
So, after solving we get [tex]\mathbf{(f-g)(x)=-4x^3+7x^2+5x-8}[/tex]

The range of lengths the third piece of wood would be 3 < x < 37 .
Using triangle inequality theorems, which states that the sum of two side lengths of a triangle is always greater than the third side.
Therefore,
A triangle with sides x, y and z will be as follows;
x + y > z
x + z > y
y + z > x
Therefore, for the woods to form a triangular piece. The third length will be in the range 4 inches to 36 inches.
Let's text the rules for the end points
20 inches + 17 inches > 4 inches
20 inches + 4 inches > 17 inches
17 inches + 4 inches > 20 inches
20 inches + 17 inches > 36 inches
20 inches + 36 inches > 17 inches
17 inches + 36 inches > 20 inches
Therefore, the range of length for the third piece of wood would be
3 < x < 37

How many text messages would you have to send for the plans to cost the same? If you send an average of 1200 text messages a month, which company would you want to choose as your provider?
a. Define your variables &Write your system of equations
b. Use your equations to solve. Make sure you label your answer
Answers
Number of tests made =x
Verzon C(x) = 45 + 0.1x => 45+0.1*1200 =165
AT & T C(y) = 30 + 0.13x=> 30 + 0.13*1200=186
For 1200 texts C(x) is less than C(y)
If the costs are to be the same then
45 + 0.1x = 30 + 0.13x
15=0.03x
15/0.03= x
500=x
