The slope of line m is 7/8. If n⊥m, what is the slope of line n? A) 7/8
B) 8/7
C) -7/8
D) -8/7

Answers

Answer 1
Answer: k:y=m_1x+b\nl:y=m_2x+c\n\nl\ \perp\ k\iff m_1m_2=-1
We have:
m_1=(7)/(8);\ m_2=?
Substitute:
(7)/(8)m_2=-1\ \ \ \ |\cdot(8)/(7)\n\nm_2=-(8)/(7)
Answer: D)
Answer 2
Answer: Hey there !

When two lines are perpendicular , the product of their slope is -1 ,

m1 × m2 = -1
7/8 × m2 = -1

m2 = -8/7 Ans.

Two numbers have a sum of 71 and a difference of 37 (PLEASE HELP ME,MY TEACHER HATES ME)

Answers

The right answer for the question that is being asked and shown above is that:

Two numbers have a sum of 71 and a difference of 37
x + y = 71
x - y = 37

So in order to get the two numbers, here it is:
x + y = 71
x - y = 37
------------
2x = 108
x = 54
y = 71 - 54
y = 17

So the two numbers are 54 and 17

Which is a solution to the equation?(x −2)(x + 5) = 18

x = −10
x = −7
x = −4
x = −2

Answers

If you would like to know the solution to the equation (x - 2) * (x + 5) = 18, you can calculate this using the following steps:

(x - 2) * (x + 5) = 18
x^2 + 5x - 2x - 10 = 18
x^2 + 3x - 28 = 0
(x + 7) * (x - 4) = 0
1. x = - 7
2. x = 4

The correct result would be x = - 7.

The solutions to the equation are x = - 7 and x = 4

What are equation solutions?

Equation solutions are the true values of x in the equation

The equation is given as:

(x - 2)(x + 5) = 18

Expand the equation

x^2 + 5x - 2x - 10 = 18

Subtract 18 from both sides

x^2 + 3x - 28 = 0

Factorize the expression

(x + 7) * (x - 4) = 0

Solve for x

x = - 7 and x = 4

Hence, the solutions to the equation are x = - 7 and x = 4
