Answer:
8.28%
Step-by-step explanation:
According to the U.S. Census Bureau, the legal official department in charge of the National Census every ten years, the population of the U.S.A in 2010 was<em> 308,745,538 inhabitants.</em>
If about 25,585,000 had diabetes, then <em>cross multiplying</em>
308,745,538-------100%
25,585,000---------x%
and
and so, about
Americans had diabetes in 2010.
Answer:
-9
Step-by-step explanation: a negative multiplied or divided by a positive will give you a negative answer
Answer:
Step-by-step explanation:
Use the sum-product pattern
Common factor from the two pairs
Rewrite in factored form
Answer: y=-5
Step-by-step explanation:
A horizontal line appears on the graph if it goes through the y-axis. Knowing this, the coordinate tells us that the y-coordinate is -5. This tells us that the equation of the line is y=-5.
1.) The answer is (B) No, because direct variation is written as y = kx, but the problem was not written that way.
2.) Answer: Yes; if you write x = ky, you will find that each x value given multiplied by a common k equals a corresponding y value.
3.) Answer: No; each x value does not multiply by a constant k to get the y values.
4.) Answer: Yes; each x value multiplies by 2.2 to get each corresponding y value.
5.) Answer: B; this is the only one that isn't or can't be written in y = kx form.
6.) Answer: Yes & -3; y + 3x = 0 can be written as y = -3x, which is a direct variation equation. The constant is just the -3.
