Answer:
[tex]y=x^{2} +8x+12[/tex] is the quadratic function.
Step-by-step explanation:
We know that -6 and -2 are the zeros. So, they are both equal to x.
x = -6 and x = -2
Add them to x.
(x + 6) (x + 2)
Now, multiply the two binomials together.
[tex]x^{2} +6x+8x+12[/tex]
Combine like terms.
[tex]y=x^{2} +8x+12[/tex]
[tex]y=x^{2} +8x+12[/tex] is the answer.

Solve the proportion.
5/6 = 10/x÷1
x = ?
Given expression:
[tex]\frac{5}{6}[/tex] = [tex]\frac{10}{x /1}[/tex]
Find x;
To find x, let us first cross multiply;
5 x (X /1) = 6 x 10
We know that any number divided by 1 will give back that same number; so the value of the expression in the parentheses is x
5 x X = 60;
So, divide both sides by 5 to give the value of X;
X = [tex]\frac{60}{5}[/tex] = 12
The value of X is 12

What is the slope of the following graph?
Answer:
-3/2
Step-by-step explanation:
Given f(x) = -7x + 9, what is the slope and y-intercept?
Answer:
7x is the slope,9 is the y-intercept
Step-by-step explanation:
7x is the constant/unit rate,9 is what gets added after which makes the expression non-proportional.
What is the definition of no solution?
Answer:
No solution would mean that there is no answer to the equation.
Step-by-step explanation:
It is impossible for the equation to be true no matter what value we assign to the variable. Infinite solutions would mean that any value for the variable would make the equation true.
There is no answer to that problem. There is either a critical error in the problem, or it's just impossible to calculate. For example, x/0 is literally nothing. You can't solve it.

You can multiply -2.2 by 6.2 to find the total variation in water level. What decimal represents the total variation in water level that Ericka observed?
Answer:
-13.64
Step-by-step explanation:
no explanation needed. Hope this really helps! :):) :) :) :)
13.64 decimal represents the total variation in water level that Ericka observed.
What are mathematical operations?The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.
Given, You can multiply -2.2 by 6.2 to find the total variation in water level.
Since it is already given that the multiple of -2.2 and 6.2 will give the total variation of water level.
Thus, the decimal represents the total variation in water level that Ericka observed = -2.2 * 6.2
the decimal represents the total variation in water level that Ericka observed = 13.64
therefore, the decimal represents the total variation in water level that Ericka observed is 13.64.

in a school 46% of the 300 students are boys. how many girls are in the class than boy?
Answer:
138 of the students are boys, and 162 of them are girls. there are 24 more girls than boys.
Step-by-step explanation:
multiplying a number by its percent as a decimal gets you the percent of that number
300 x .46 = 138 boys
now subtract that from the original 300 to get the girls
300 - 138 = 162 girls
lastly subtract the girls from the boys to get how many more girls there are than boys
162 - 138 = 24
