What is an equation of the line that is perpendicular to y+1=-3(x-5) and passes through the point 4,-6
Oliga [24]

Answer:

y=\frac{1}{3}x-\frac{16}{3}

Step-by-step explanation:

Arranging the given equation in slope-intercept form ( y = mx + b ):

y+1=-3(x-5)\\y+1=-3x+15\\y=-3x+15-1\\y=-3x+14

<em>We know that the perpendicular line would have a slope (m) that is </em><em>negative reciprocal </em><em>of this (\frac{1}{3}). Thus we can write the perpendicular line's equation as  y=\frac{1}{3}x+b. </em>

<em />

<em>Now putting x = 4 and y = -6 into the equation, we can solve for b:</em>

<em>y=\frac{1}{3}x+b\\-6=\frac{1}{3}(4)+b\\-6=\frac{4}{3}+b\\b=-6-\frac{4}{3}\\b=-\frac{16}{3}</em>

<em />

Thus, the equation of the perpendicular line is  y=\frac{1}{3}x-\frac{16}{3}

Answer:

B. 0

Step-by-step explanation:

2-2/5-2= 0/3= 0

Another way to look at this is that because they have the same y coordinate, it must simply be a horizontal line, which has a slope of 0

Given the function f(x)=-2x^2+6x ,then what is f(x)=−3 as a simplified polynomial?
GenaCL600 [577]

The given function, f(x) = -3, written as a simplified polynomial is 2x² - 6x- 3 = 0

<h3>Simplified Polynomials</h3>

From the question, we are to determine f(x) = -3 as a simplified polynomial

From the given information,  we have that

f(x) = -2x^2 + 6x

Rewrite the the given equation properly.

Rewriting, we get

f(x) = -2x² + 6x

Also, from the given information

We have that

f(x) = -3

Thus, we can write that

- 3 = -2x² + 6x

Writing the above equation as a simplified polynomial, we get

- 3 = -2x² + 6x

2x² - 6x- 3 = 0

Hence, the given function, f(x) = -3, written as a simplified polynomial is 2x² - 6x- 3 = 0
