Answer: A, I think
Step-by-step explanation:
Answer:
y - 3 = (1/2)(x - 4)
Step-by-step explanation:
The graph is hard to read, but we can make assumptions about the x- and y-values shown. The y-intercept appears to be (0, 1) and the blue dot appears to be (4, 3). Let's try finding the equation of the line using this assumed data:
The point-slope equation is y - k = m(x - h), where (h, k) is a point on the line and m is the slope of the line.
We need the slope of the line. Recall that m = rise/run. Going from (0, 1) to (4, 3), x (the 'run') increases by 4 and y (the 'rise') increases by 2. Thus, the slope is m = rise/run = 2/4, or 1/2.
Substituting the known values into the point-slope equation y - k = m(x - h), we get:
y - 3 = (1/2)(x - 4)
(5 - 3i) - (4 + 6i) Remove the brackets. Be careful with those on the right.
5 - 3i - 4 - 6i Did you notice how the second set worked. That - sign affected both terms inside the brackets. Now collect your like terms.
5 - 4 - 3i - 6i The - 3i and - 6i act like money. You are three dollars in the hold and you spend another 6. Where does that put you ?
1 - 9i You are now 9 dollars in the whole.
A. (-1.15)×3.2 = -(1.15×(3 + .2))
... = -(1.15×3 + 1.15×.2) = -(3.45 + 0.23)
... = -3.68
B. There are two factors in the product, one of which is negative. The total number of negative factors is an odd number, so the product will be negative.
You can also enter the numbers with their signs into a calculator, and it will correctly calculate the sign of the product.
