Two perpendicular lines intersect at the origin. If the slope of the first line is 3, what is the equation of the second line?.

Answers

Answer 1

Answer: The slope of the line perpendicular to a line with a given slope is its negative reciprocal. Hence, the new slope is -1/3. The equation of the line given slope and point can be generally expressed as,
y - y1 = m(x - x1)
Substituting,
y - 0 = (-1/3)(x - 0)
The final equation would be,
x + 3y = 0

Answer 2

Answer: if slope of first line is 3 and is perpendicular to second line
then second line has a slope of -1/3

Formulate the quadratic function that contains the points (-1,2), (0,-1) and (2,5). F(x) = 2x2 - x - 1 f(x) = 2x2 x 1 f(x) = 2x2 - x 2 f(x) = 2x2 - x - 2.

Answers

Answer:

(a) F(x) = 2x^2 - x - 1

Step-by-step explanation:

The quadratic regression function of a graphing calculator does this nicely.

The one attached shows the function to be ...

F(x) = 2x^2 -x -1

Additional comments

The supplied point (0, -1) tells you the y-intercept is -1. That means the constant in the function's equation will be -1. Only one answer choice has that.

F(x) = 2x^2 -x -1

As always, the first step in problem solving should be to look at the problem, and look at the available solution choices. Understanding these things will generally allow you to throw out answer choices that don't provide a sensible answer to the question. Here, that leaves you with only one answer choice, which is all you need.

points of intersection.

Answers

Answer:

2 points of interception of (3.12 , 12./12) and (-5.12 , 3.87)

Step-by-step explanation:

y − x = 9

y = x + 9

x+9 = x²+3x-7

x²+2x-16=0

x = (-2±√2²-4(1)(-16)) / 2 = (-2 ± √68) / 2 = -1 ± √17

x = 3.12 or x = -5.12

y = 12.12 or y = -3.87

Brianna asked 45 students if they would vote for her to be student council president. She used her calculator to compare the number of students who said yes with the total number of students. Her calculator showed the result as 0.6222... 1. Write this number as a fraction (Steps)
2. How many students said they would vote for Brianna?

Answers

0.6222... is a recurring decimal at the digit '2'

let x = 0.62222....

multiply x by 10 ⇒ 10x = 6.2222.... [we multiply by 10 to leave the recurring digits after decimal point]

multiply x by 100 ⇒ 100x = 62.2222... [we multiply by 100 so that we can again leave the recurring digit after decimal point]

subtract 10x from 100x
100x - 10x = 62.2222... - 6.2222...
90x = 56
x = 56/90
x = 28/45

There are 28 students would vote for Brianna
