please help me answer this slope question!
FIND SLOPE OF THE LINE ( give me the coordinates too!)
Answers
Answer:
Slope = -1/2.
Step-by-step explanation:
2 points on the line are (10, 0) which is where the line passes through the x-axis and (0, 5 ) where it passes through the y-axis.
The slope = (difference in y coordinates) / ( corresponding difference in x coordinates)
= (5 - 0) / (0 - 10)
= -5/10
= -1/2.

Part D How many of the 320 million Americans would you predict wear CORRECTIVE lenses?
Answers
Answer:
320,000,000 * 0.638 = 204,160,000
Step-by-step explanation:
Assuming the sample is a good representation of the people from the United States.
Since there were 1,000 surveyed... and 638 of them were wearing glasses, that makes a proportion of 638 out of 1,000 people, or 63,8 / 100 people... so 63.8%... or 0.638
So, if we assume that the US population is of 320 million, how many people does that make wearing glasses.... we just have to multiply 320M by 0.638

Find the tangent line approximation to 21/x near x = 21.
21/x≈
Answers
Answer:
y = -0.05x + 2.05
Step-by-step explanation:
y = 21/x = 21x^-1
y' = -21x^-2 = -21/x^2
At x = 21 slope = -21/(21)^2 = -0.05 to nearest hundredth.
Tangent line is y - 1 = -0.05(x - 21)
y = -0.05x + 1.05 + 1
y = -0.05x + 2.05

Answer:

Step-by-step explanation:
Let's think about a few simple examples. Once you understand them, you
will be able to put them together to make harder problems.
Ex: What is 2 divided by 1/5? Here are 2 blocks:
+---------+---------+
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | |
+---------+---------+
Here is 1/5 of a block (the shaded part):
+---------+
|XXXXXXXXX|
+.........+
| |
+.........+
| |
+.........+
| |
+.........+
| |
+---------+
To divide 2 by 1/5, we divide 2 blocks into pieces the size of the 1/5
block.
+---------+---------+
| | |
+.........+.........+
| | |
+.........+.........+
| | |
+.........+.........+
| | |
+.........+.........+
| | |
+---------+---------+
There are 10 pieces this size in the 2 blocks. In other words,
2 divided by 1/5 = 10
That's the same as
2 x 5 = 10
Do you see why? To make 1/5 size blocks, we had to make each whole
block into 5 pieces. In other words, we multiplied the number of
pieces by 5.
Next problem:
2 divided by 2/5 = ?
Here is 2/5 of a block (the shaded part):
+---------+
|XXXXXXXXX|
+.........+
|XXXXXXXXX|
+.........+
| |
+.........+
| |
+.........+
| |
+---------+
Let's divide the 2 blocks into pieces this size.
+---------+---------+
| | |
+ + +
| | |
+.........+.........+
| | |
+ + +
| | |
+.........+.........+
| |
+---------+---------+
The bottom block is a different shape, but it's the same size, because
it's made of 2 1/5-size pieces. Since the pieces we want are twice as
big, there are only 1/2 as many of them. The answer is
2 divided by 2/5 = 10/2 = 5
This is the same as
2 x 5/2 = 5
Do you see how the two equations are related? You take the fraction,
2/5, and "turn it upside down" (in math words, we say "invert the
fraction," or "take its reciprocal"). Then replace the division sign
by a multiplication sign.
Now we can tackle harder problems. The same method always works, even
if the answer isn't a whole number as in the simple examples. For
instance,
5 divided by 3/8 = ?
Ex: Invert the fraction 3/8; you get 8/3. Then multiply by this fraction:
5 x 8/3 = 40/3 = 13 1/3
We can even replace the whole number in the problem with a fraction,
like this:
5/7 divided by 3/8 = ?
5/7 x 8/3 = ?
5 8 40 19
--- x --- = ---- = 1 ----
7 3 21 21
If you are comfortable with multiplying fractions, then you will have
no trouble dividing fractions. Just remember: invert the fraction you
are dividing by (the divisor), and multiply instead of dividing. Hope this helps! :)
what is 12x12-11+14-18=?
Answers
Answer:
129
Step-by-step explanation:
First we check for parentheses which there is none.
We would first do 12 x 12=144
Then we would do addition and subtraction left to right.
so just in order.
Second we would do 144 - 11=133
Third we would do 133 + 14=147
And last 147 - 18=129 And there's your answer.
Hope it helps have a great day:)

12 or 10 or 9 or 8?
Answers
Answer:
The other factor is 12⇒ A
Step-by-step explanation:
The factors of a number are all the numbers multiplied to form this number
Examples:
The factors of 12 are 1, 2, 3, 4, 6, 12 because
1 × 12 = 12
2 × 6 = 12
3 × 4 = 12
∵ The product of numbers = 1236
∵ One factor of that number is 103
∴ ------ × 103 = 1236
→ Divide the number by its factor to find the other number
∴ 1236 ÷ 103 = -------
∵ 123 ÷ 103 = 1 R 20
∵ 206 ÷ 103 = 2
∴ 1236 ÷ 103 = 12
∴ The other factor is 12

x^2+5y^2+2y=75; dx/dt =14 when x= 6 and y=-3; find dy/dt
Answers
Answer:
7
Step-by-step explanation:
x² + 5y² + 2y = 75
2x + 10y * dy/dx + 2 dy/dx = 0
2x + (10y + 2) dy/dx = 0
x + (5y + 1) dy/dx = 0
when x = 6, y = -3
6 + (-15 + 1) dy/dx = 0
6 - 12 dy/dx = 0
dy/dx = 1/2
dy/dt = dy/dx * dx/dt = 1/2 * 14 = 7
