Write the equation of a line perpendicular to the line y = 2x - 3 that goes through point (4, 3)

Mathematics
1 answer:
iragen [17]3 years ago
5 0

Answer:

y = -1/2x + 5

Step-by-step explanation:

To get the perpendicular line first, take the negative reciprocal of the slope.

2 -> -1/2

So far, the equation is y - -1/2x ± b. (since we are using mx + b)

Since you want the point (4, 3) to cross over the line, we substitute values in.

3 = -1/2(4) + b

3 = -2 + b

b = 5

Your equation that fits the answer is -1/2x + 5.

Your welcome!

Hello there!

It would be their slopes are equal but y-intercepts are not equal.


Hope This Helps You!

6. A stoplight at an intersection stays red for 60 second, changes to green for 45
erica [24]

Answer:

0.75 = 75% probability that he will have to wait at a red light for more than 15 seconds

Step-by-step explanation:

At each second, the stoplight is equally likely to change, which means that we use the uniform probability distribution to solve this question.

Uniform probability distribution:

Has two bounds, a and b. The probability of finding a value higher than x is given by:

P(X > x) = \frac{b - x}{b - a}

Red for 60 seconds

So when Jamal arrives it can change in any number of seconds between 0 and 60, that is, a = 0, b = 60

Probability that he will have to wait at a red light for more than 15 seconds?

P(X > 15) = \frac{60 - 15}{60 - 0} = \frac{45}{60} = \frac{3}{4} = 0.75

0.75 = 75% probability that he will have to wait at a red light for more than 15 seconds

Write a system of linear equations for the graph below. <br> y=?<br> y=?
Tju [1.3M]

y = 6x + 6 is a system of linear equations for the graph.

<h3>Explain about the linear equations?</h3>

If a variable's maximum power is always 1, an equation is said to be linear. As a one-degree equation, it also goes by that name. An equation with one variable that has the usual form Ax + B = 0 is a linear equation. A coefficient, B is constant, and x is a variable in this situation.

Ax+By=C represents a two-variable linear equation in its standard form. As an illustration, the conventional form of the linear equation 2x+3y=5 It is rather simple to locate both intercepts when an equation is stated in this way (x and y).

First order equations include linear equations. In the coordinate system, the linear equations are defined for lines. A linear equation in one variable is one in which there is a homogeneous variable of degree 1 (i.e., only one variable).

Slope = y2- y1 /x2- x1

if these points are x (0,-6) y (1 ,-5)

         1 +5/ 0 +6 = 6

Equation for the line through (0, -6) and slope is slope = (6),

y - y' = m(x - x')

y - 6 = (6)(x- 0) (x- 0)

y - 6 = 6x

y = 6x + 6
