is the equation best represents the line.
Solution:
Take any two points on the line.
Let the points be (0, –4) and (4, 7).
General form of equation of a line is y = mx + c
where m is the slope and c is the y-intercept of the line.
<em>y-intercept is the point which line crosses at y-axis.</em>
In the given line, y-intercept is 4.
c = 4
Slope of the line:
Equation of the line:
y = mx + c
Hence is the equation best represents the line.
Answer:
the roots are 5 and -3
Step-by-step explanation:
factorise and you should get (n+3)(n-5)
Step-by-step explanation:
1/5x + 5x = 7x-18
now that the equation is formed, just find x!
move the whole numbers to one side,
5x-7x+1/5x = -18-1/5x
-2x+1/5x = -18
-1.8x = -18
x = 10
and to find out if 10 is the right value of x, just subsitute 10 back into the very first equation and if it balances out to 0 it ia the right answer. hope i helped!

The scale factor of the dilation of polygon ABCD to polygon PQRS is: 3/2.
<h3>How to Determine the
Scale Factor of a Dilation?</h3>
Dilation means the enlargement or reduction of a polygon. If a polygon is enlarged, the new image formed after dilation is bigger than the original image. If the dilation is a reduction, the new image formed is smaller than the original image. The formula for determining the scale factor of a dilation is given as;
- Scale factor = Dimension of new image / corresponding dimension of original image.
We have the following:
Dimension of new image after dilation = PS = 3 units
Corresponding dimension of original image before dilation = AD = 2 units
The scale factor of the dilation = 3/2
In conclusion, the scale factor of the dilation of polygon ABCD to polygon PQRS is: 3/2.
