Answer:
- 1/2
Step-by-step explanation:
We use the slope-intercept form to figure out our slope.
y = mx + b
Get y alone:
x + 2y = -8
2y = -x - 8
y = -x/2 - 4
Since m is the slope in y = mx + b, we can see that -1/2 is in the place of m, therefore our slope is -1/2
Answer:
2/5
Step-by-step explanation:
(2/3) * (3/5) = 2/5
I think it is 2/5, but the problem seems a bit odd.

Answer:</h3>
- C. (9x -1)(x +4) = 9x² +35x -4
- B. 480
- A. P(t) = 4(1.019)^t
Step-by-step explanation:
1. See the attachment for the filled-in diagram. Adding the contents of the figure gives the sum at the bottom, matching selection C.
2. If we let "d" represent the length of the second volyage, then the total length of the two voyages is ...
... (d+43) + d = 1003
... 2d = 960 . . . . . . . subtract 43
... d = 480 . . . . . . . . divide by 2
The second voyage lasted 480 days.
3. 1.9% - 1.9/100 = 0.019. Adding this fraction to the original means the original is multiplied by 1 +0.019 = 1.019. Doing this multiplication each year for t years means the multiplier is (1.019)^t.
Since the starting value (in 1975) is 4 (billion), the population t years after that is ...
... P(t) = 4(1.019)^t
The answer is going to be 8 and 80.
Answer:
10 x + 2 x^2
Step-by-step explanation:
Expand the following:
2 x (x + 5)
Hint: | Distribute 2 x over x + 5.
2 x (x + 5) = 2 x×5 + 2 x x:
2 x×5 + 2 x x
Hint: | Multiply 2 and 5 together.
2×5 = 10:
10 x + 2 x x
Hint: | Combine products of like terms.
2 x x = 2 x^2:
Answer: 10 x + 2 x^2
