slope of a line that is perpendicular to the line y=-3x is 1/3

What is slope of line?

A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate. Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively. where "m" represents a line's slope. So, the slope of a line is tanθ.

y=-3x

tanθ=slope = y/x= -3

Slope(M) of this equation is -3

Let the slope of its perpendicular line is m

As we know that the product of the slopes of perpendicular lines is -1

so,

M*m =-1

-3 * m= -1

m=1/3

What does it mean when the ratio of person 1’s income to person 2’s incomes is 1 to 3 or 3 to 1? Explain.
viktelen [127]

Answer with explanation:

3:1 means that person 1's income is three times person 2's income.

E.g.: if person 1 gets 150 per hour, person 2 gets 30 per hour.

1:3 means that person 1's income is one third of person 2's income.

E.g.: if person 1 gets 40 per hour, person 2 gets 120 per hour.

Determine if the following system of equations has no solutions, infinitely many
FrozenT [24]

Answer:

infinitely many solutions

Step-by-step explanation:

x + 6y = -5

3x + 18y = -15

Multiply the first equation by 3

3(x + 6y) = -5*3

3x + 18y = -15

The two equations are identical.  This means they have infinite solutions along the line x+6y = -5

Click on the photo to get a better view, I really don’t understand it
zaharov [31]

Answer:

1)107

2)43

Step-by-step explanation:

Triangles interior angles add up to 180 degrees. In the first one, the first two angles are 31and 42, and if interior angles add up to 180, the equation should be 31+42+x=180 x=107.

Second one is hardes. A square means a right angle, or 90 degrees. 180-90 is 90. Next, we have the two angles x, and x+4 We know that triangles interior angles add up to 180 degrees, so x+x+4+90=180 2x+94=180 2x=86 x=43

Hope this helps :D Please mark brainliest if correct :D
