Answer:
The answer to your question is x = 4
The function is y = 3(x+3)^2-9
The equation of a parabola is
y=a(x-h)^2+k
where (h,k) are the coordinates of the vertex and a, is a constant.
From the question, we have
(h,k)=(-3,-9)
⇒y=a(x+3)^2-9
To find a, substitute x=-2,y=-6
-6=a(-2+3)^2-9
⇒a=3
The equation, y=3(x+3)^2-9
Multiplication:
Mathematicians use multiplication to calculate the product of two or more numbers. It is a fundamental operation in mathematics that is frequently utilized in everyday life. When we need to combine groups of similar sizes, we utilize multiplication. The fundamental concept of repeatedly adding the same number is represented by the process of multiplication. The results of multiplying two or more numbers are known as the product of those numbers, and the factors that are multiplied are referred to as the factors. Repeated addition of the same number is made easier by multiplying the numbers.

Answer: NO.
Step-by-step explanation:
We know that , the 95% confidence interval indicates that the researcher can be 95% sure that the true value of population mean falls in it.
Given : A company is interested in estimating the costs of lunch in their cafeteria.
After surveying employees, the staff calculated that a 95% confidence interval for the mean amount of money spent for lunch over a period of six months is ($720, $900).
Then, the correct interpretation would be : The company can be 95% sure that the true value of population mean falls in it.
Answer:
x=10
Step-by-step explanation:
4(x+7)-7x+2
4x+28-7x+2
4x-7x =-3x 28+2=30
-3x+30=0
-3x=-30
