It would be 35.77. The 6 is in the hundredths place, so you look to the number to its right. If the number is 0-4, keep the number the same. If it's 5-9, round up.
To solve this, plug 2b+1 in for a. :
4(2b+1)-5. Solve for b.
First use the distributive property:
8b+4-5=?
Combine like terms:
8b-1=?
Solve for b.
add 1 to both sides.
8b=1
Divide both sides by 8.
b=1/8
Line 1: We are given the points (-3, 1) and (-7, -2).
Line 2: We are given the points (2, -1) and (8, 4).
In order to calculate the slope, we use the formula:
m = (y2-y1)/(x2-x1)
Substitute in the points to find the slope.
Line 1: (-2 - 1)/(-7 - (-3)) = -3/-4 = 3/4.
Line 2: (4 - (-1))/(8-2) = 5/6.
Answer:
What is the concentration of H+ ions at a pH = 2?
⇒ 0.01 mol/L
What is the concentration of H+ ions at a pH = 6?
⇒ 0.000001 mol/L
How many more H+ ions are there in a solution at a
pH = 2 than in a solution at a pH = 6?
⇒ 10,000
Step-by-step explanation:
1. 2^6.
2. 2^3.
3. 3^7
4. 6x^4
5. 4x^2
6. 12n^5
7. 9x^2
To find the answer of these questions, add the exponents. If there is whole numbers in the problem, you have to multiply the numbers. For number 7, do 3^2 and x^2. Hope this helps!
