The equation of a line which has the slope m and passes through the point A(x1,y1) has the formula:
y-y1=m(x-x1)
in your case m= -5 ; A(x1;y1)=(1;-1)
y-(-1)= -5(x-1)
y+1= -5(x-1)
answer is c

Answer:

The answer to the question is C) y + 1 = -5(x - 1)

Step-by-step explanation:

In order to find this, we start by looking at the base form of point-slope form.

y - y1 = m(x - x1)

Now we put the slope in for m and the point in for (x1, y1)

y + 1 = -5(x - 1)

Multiply the Polynomials:<br><br> (2x+3) (-x+2y-4)
GREYUIT [131]

The result of multiplying the polynomials is (2x + 3) (-x + 2y - 4) = -2x² + 4xy - 11x + 6y - 12

<h3>How to multiply the polynomials?</h3>

The polynomial expression is given as

(2x + 3) (-x + 2y - 4)

Expand the brackets in the above polynomial expression

So, we have

(2x + 3) (-x + 2y - 4) = 2x * (-x + 2y - 4) + 3 * (-x + 2y - 4)

Open the brackets in the above polynomial expression

So, we have

(2x + 3) (-x + 2y - 4) = -2x² + 4xy - 8x + -3x + 6y - 12

Evaluate the like terms in the above polynomial expression

So, we have

(2x + 3) (-x + 2y - 4) = -2x² + 4xy - 11x + 6y - 12

Hence, the solution is -2x² + 4xy - 11x + 6y - 12

Reflect across the line x=-3​
SOVA2 [1]

Answer:

When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x).

Step-by-step explanation:

this is npt the answer but will help you towards the answer

A plot of land doubles in size by adding x meters to the length and x meters to the width of the land. if the original plot had
ladessa [460]
Lets write as an equation the info provided in the problem:
original area = 200*300 = 60000 squared meters
Adding x meters to the length is: 300 + x
Adding x meters to the width is: 200 + x
If the area doubles in size we have: 2*<span>60000
Now writing as a single equation all info:
(300 + x)(200 + x) = 120000
We have to make the operations and solve:
60000 + 300x + 200x + x^2 = </span><span>120000
x^2 + 500x - 60000 = 0
This is a squared trinomial, to solve it we need two numbers that subtracted give us 500 and multiplied -60000:
(x + 600)(x -100) = 0
So there are two solutions, x = -600 and x = 100, we choose the positive one:
x = 100
thererefore the value of x is 100 meters</span>
