Answer:
8
Step-by-step explanation:
6x + 45 + 3x = 180
9x - 45 = 180
9x = 135
x = 15
Answer: you can only add like terms, for example; 2x + 3x = 5x as they both have an x next to the numbers.
you cannot simplify 2 + 4x as they both don’t have an x next to them.
hence why, the answer to 2x^2 + 15x^2 would be 17x^2
Step-by-step explanation:
40,023,032 = (4 x 1000000000) + (0 x 100000000) + (0 x 10000000) + (0 x 1000000) + (2 x 100000) + (3 x 10000) + (0 x 1000) + (0 x 100) + (3 x 10) + (2 x 1)
No the correct answer is c. If you use the formula
Y2- Y1
X2-X1
You could use this to find the slope. And then the y-intercept if any.
