Step-by-step explanation:
x² + 4x - 9
= (x + 2)² - 13
a = 2, b = -13.
Answer:
The value of g that makes the statement true is 11.
Step-by-step explanation:
The statement is 26 = 7(g - 9) + 12 wich is an equation. In order to find the value of g that satisfies the equation we need to isolate the variable of interest, in this case g. We have:
7*(g-9) + 12 = 26
7*(g-9) = 26 - 12
7*(g-9) = 14
(g-9) = 14/7
(g-9) = 2
g = 2 + 9 = 11
The value of g that makes the statement true is 11.
Answer:
The 
of the clean compound is approximately 10.495.
Step-by-step explanation:
If the cleaning ion concentration of the cleaning compound is ![[H^{+}] = 3.2\times 10^{-11}](https://tex.z-dn.net/?f=%5BH%5E%7B%2B%7D%5D%20%3D%203.2%5Ctimes%2010%5E%7B-11%7D)
, then the , no unit, of the compound is:
![pH = -\log_{10} [H^{+}]](https://tex.z-dn.net/?f=pH%20%3D%20-%5Clog_%7B10%7D%20%5BH%5E%7B%2B%7D%5D)
(1)
The of the clean compound is approximately 10.495.
Answer:
true!
Step-by-step explanation:
plug in 1.1
3 + 51(1.1) = 59.1
3 + 56.1 = 59.1
59.1=59.1
Y=-2x+b
1=-2*(1)+b
1=-2+b
B=1+2=3
Y=-2x+3
2x+y-3=0
