Answer:
A) -7/9
Step-by-step explanation:
-4(x + 4x) = 2(2 - x) + 10
-4x - 16x = 4 - 2x + 10
-4x - 16x + 2x - 4 - 14 = 0
-18x -14 = 0
-18x = 14
x = - 14/18
x = - 7/9

Answer: y = 9x - 14
Step-by-step explanation:
The equation of a line is y = mx + b
We know the slope is 9 so so far the equation we have is y = 9x + b.
Since we know (1,-5) is a point on the line, we can plug in the x and y values into the equation and we get:
-5 = 1*9 + b
-5 = 9 + b
b = -14.
Therefore, the equation of the line is y = 9x - 14
7 times 7 = 49. Perfect square.
3 times 3 = 9. Perfect square.
15 times 15 = 225. Again, a perfect square.
The other two, 17 and 143, come out as decimals. So, your final answer would be 49, 7 and 225. Hope it helps! If you could vote my answer as the brainiest, that would be awesome! :)
