The pH of distilled water is usually LESS THAN 7, because when it contacts air CO2 gas begins dissolving into the water.
Our system of equations is:
y = -3x + 9
y = -x - 5
To solve this system of equations, we are going to use substitution. This means that we are going to substitute the second equation into the first equation since both are already solved for y in terms of x.
y = -3x + 9
-x - 5 = -3x + 9
Now, we must simplify by moving all of the constant terms to one side of the equation and all of the variable terms to the other side.
-x - 5 = -3x + 9
2x - 5 = 9
2x = 14
Finally, to undo the multiplication between the coefficient 2 and the variable x, we must divide both sides by 2 to get the variable x alone.
x = 7
Next, we must substitute in this value we have solved for x into one of the original equations to solve for the other variable, y.
y = -3x + 9
y = -3(7) + 9
To simplify, we must multiply through the parentheses and combine like terms by addition.
y = -21 + 9
y = -12
Therefore, your final answer is x = 7 and y = -12, or as an ordered pair (7, -12).
Hope this helps!
<span>x = –4c
</span>if c = -2 then x = -4(-2) = 8
I believed you had a typo, function should be f(x) = -3x^2 - 4x
so
<span>f(x) = -3x^2 - 4x
</span>f(x) = -3(8^2) - 4(8)
f(x) = -3(64) - 32
f(x) = -192 - 32
f(x) = -224
answer
<span>C.

Answer:
Dichotomous question
Step-by-step explanation:
Dichotomous question is a type of question that required answer in yes or no, sometimes in true or false and may be right or wrong.
They generally used for clear clarification of the questions asked. they have been asked to get the clear percentage of the qualities.
let take an example of Dichotomous question.
1) have you ever been into particular restaurant.
2) height of this boy is more than 5 feet or not
The y asymptote in a function refers to the horizontal asymptote, or the horizontal line that function generally does not go through. If the degree of the numerator is less than the degree of the denominator, the horizontal asymptote is the x axis, or y = 0. If the degrees in the numerator and denominator are the same, then the asymptote is y = 1. If the degree in the numerator is higher than the degree of the denominator the asymptote is oblique, or a straight line. I am going to attempt to attach a graph with an asymptote of y = 0 ( the degree of the numerator is less than the degree of the denominator) and one with an oblique so you can see the difference. There are also vertical asymptotes, but that's another concept.
