Hey!
-----------------------------------------------
Solution:
4(9x + 7) = x - 4
36x + 28 = x - 4
36x + 28 + 28 = x - 4 + 28
36x = x + (-32)
36x - x = x - (-24) - x
35x = -32
35x/35 = -32/35
x = -32/35
-----------------------------------------------
Answer:
x = -32/35
-----------------------------------------------
Hope This Helped! Good Luck!
X² +18x = 0
To complete the square we are going to use formula a² +2ab +b² = (a+b)²
x² +2*9*x = 0
x² +2*9x+9² = 9²
(x+9)² = 9²
√(x+9)² = +/-√9²
x+9 = 9, or x+9 = -9
x=0, or x= - 18
The equation could be solved different way
x² +18x = 0
x(x+18) = 0
x=0 or x+18=0
x=0 or x=-18
An acute angle has a measure between 0 degrees and 90 degrees.
An obtuse angle has a measure between 90 degrees and 180 degrees.

Answer:
Negative
Step-by-step explanation:
If a line has a positive slope, then y always increases when x increases and y always decreases when x decreases. Thus, the graph of the line starts at the bottom left and goes towards the top right.
