Answer:
1/ab
Step-by-step explanation:
Complete question
Find the slope of the line containing the points whose coordinates are(a,1/b) and (b,1/a)
Slope is expressed as;
m = y2-y1/x2-x1
Substitute the coordinate values
m = (1/a - 1/b)/b -a
m = (b-a)/ab ÷ b-a
m = (b-a)/ab × 1/b-a
m = b-1/b-a × 1/ab
m = 1 × 1/ab
m = 1/ab
Hence the slope is 1/ab
Answer:
15 < 23
Could you include the numbers on D.? Thanks!
Step-by-step explanation:
They've been open for 15 hours, to reach 392 people. They can't be open for more than 23, because that would be more than 600 people. Therefore 23 need to be always GREATER than 15
15 < 23
see if you can find a number line that matches the expression.
Hope this helped! Please mark as brainliet! Thanks!
Me too! I'm an A/B Honor role student, but i get stuck and need help all the time. Not every one is perfect! ^_^
Pure water is a chemical compound. Every water molecule is
one oxygen atom tightly bound to 2 hydrogen atoms. That's a
big part of the reason why the chemical formula for water is H₂O .
Answer:
<u><em>3.5 °C</em></u>
Step-by-step explanation:
- To find the answer multiply 3 and 7 to get the sum of the temperatures in the first seven days.
3 x 7 = 21
- Add 21 and 8 together to get the sum of the temperatures in the first 8 days.
21 + 8 =29
- Divide 29 by 8 to get the mean temperature for the first eight days.
29 ÷ 8 = 3.5
3.5 °C
