Answer:
x = -5 , y = -5
Step-by-step explanation:
- 8y + 9x = -5
8y + 7x = -75
__________
0 + 16x = - 80
x = -80 / 16
x = -5
- 8y + 9x = -5
-8y + 9(-5) = -5
-8y - 45 = -5
-8y = -5 + 45
-8y = 40
y = 40/-8
y = -5
hope it helps!
The image of the point (8, 6) dilated by a scale factor 1/2 is (4, 3)
The given point is (8, 6)
The scale factor of dilation = 1/2
To dilate a given point (x, y) by a scale factor m, multiply each of the coordinates (x, y) by m
The image = (mx, my)
For the point (8, 6) dilated by 1/2, the image will be calculated as shown below:
The image of the point (8, 6) dilated by a scale factor 1/2 is (4, 3)

notice, a function that is decreasing, namely have a negative slope, doesn't have to be negative.
Expand the equation by multiplying it with itself: (x-3)*(x-3)
x^2 - 3x - 3x + 9 = 5
x^2 - 6x + 9 = 5
x^2 -6x +4 = 0
Since this is not part of the choices, try a different approach. Take the square root of both sides:
x - 3 = square root of 5
x - 3 = +/- 2.24
I guess this is the middle term which is incomplete. The first and last choices are not equivalent to the given equation.
Hi. I think the answer is 56%. To get the amount that is the profit you find the difference between 6.20 and 2.70 which is 3.50. Then you find 3.5/6.2 to find the percentage which is 0.56 or 56%.
