The answer is D.
You multiply 1,250,000 by 1.50= 1,875,000
Then add 1,875,000 to 1,250,000= 3,125,000
Divide by 1,000,000 and you get 3.125
It seems that the expression is - 7x + 3y - 2 + 6x -1 - y^2
like terms:
-7x + 6x = - x
3y stands alone
-2 - 1 = -3
- y^2 stands alone
Answer: - x + 3y - 3 - y^2
[note: if the last term is not y^2 but 2y, then you have to combine +3y - 2y = y and the answer would be - x + y - 3]
When a linear equation is in the form y = mx + c, the c, or constant, is the intercept on the y axis, meaning it crosses the y axis at (0, 1).
The gradient (1/3 in this case) is how much the y increments (or decrements) per increase of 1 of the value of x.
This would mean that there would be one point at (0, 1), and another at (3, 2). Draw a line from these two points and beyond, and that is the graph sketched.
question 3 = $150 because 50% is one half of 100% so 300/2 = 150
The answer is A. Hope that helps
