V+27=117
Subtract 27 to 117:
v=90
Answer:
(2,1)
Step by step explanation:
Please find the attachment.
We have been given that line 
is horizontal and passes through point (1,1). Line 
is vertical and passes through point (2,2). We are asked to find point of intersection of line and line .
Line is a horizontal line so y-coordinate will be 1 for any value of x. Line is a vertical line, so x-coordinate will be 2 for any value of y.
Therefore, intersection point of both lines will include x-coordinate of line and y-coordinate of line that is (2,1).

The answer to your question is below
Step-by-step explanation:
pH definition
pH = - log [H⁺]
a) For pH = 2.4, solution A
2.4 = -log[H⁺]
[H⁺] = antilog⁻².⁴
[H⁺] = 0.00398
For pH = 9.4, solution B
[H⁺] = antilog⁻⁹.⁴
[H⁺] = 3.98 x 10⁻¹⁰
b) Divide hydrogen-ion concentration of solution A by hydrogen-ion concentration of solution B.
0.00398 / 3.98 x 10⁻¹⁰
10000000 times
c) By 7, because 7 is the number of zeros
Answer:
Options 1 and 4 are arithmetic
Step-by-step explanation:
Arithmetic means that you are adding or subtracting a number in a sequence.
For option 1, we are adding 2 every time.
-3 + 2 = -1 -1 + 2 = 1 1 + 2 = 3
For option 4, we are subtracting 7 every time.
32 - 7 = 25 25 - 7 = 18 18 - 7 = 11
Option 2 is geometric. Geometric means you are multiplying or dividing by a number in a sequence.
2 * 3 = 6 6 * 3 = 18 18 * 3 = 54
Option 3 is actually quadratic. This is similar to a arithmetic, except instead, the amount added to the number is multiplied by 2 every time.
1 + 2 = 3 (2 + 2 = 4) 3 + 4 = 7 (4 + 4 = 8) 7 + 8 = 15
Answer:
(x-1)(x-7)
Step-by-step explanation:
To factor the equation, find two binomials which multiply to a quadratic. The quadratic's factors are found by finding two numbers that multiply to 7 and add to -8.
-1 and -7 multiply to 7 and add to -8.
(x-1)(x-7)
