Answers
The required simplified value of a is 1/2 .
Given that,
3 +0.5(4a + 8) = 9 – 2a
The simplified value of a is to be determined.
What is arithmetic?
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
What is simplification?
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
3 +0.5(4a + 8) = 9 – 2a
3 + 0.5*4a + 0.5*8 =9 - 2a
3 + 2a + 4 = 9 - 2a
7 - 9 = - 4a
a = 1 / 2
Thus, the required simplified value of a is 1/2.

The nearest whole number to decimal number 8.525 will be 9.
A decimal number 8.525 is given in the question.
We have to round it to nearestwhole number.
What will be the value ; if 2.3456 is rounded off to thousands place ?
The value will be 2.346.
As per the question ;
The given decimal number is 8.525.
We have to round it to nearest whole number
As, the number right to decimal number is greater than 500 , we need to change it to 1000. So , the nearest whole number will be ;
= 9.000 or 9
Thus , the nearest whole number to decimal number 8.525 will be 9.

B) y-intercept (0, 2)
Eliminate
C) x-intercept (-3, 0)
D) x-intercept (-1, 0)
Answers
Answer:
B
Step-by-step explanation:
x-intercepts:
factor the function
f(x)=(x+3)(x+1)
zeros at x=-3,-1
x-intercepts --> (-3,0),(-1,0)
y-intercepts:
set x=0 in f(x)
f(0)=(0)^2+4(0)+3=3
y-intercept --> (0,3)
find minimums and maximums
The max or min of a quadratic function occurs at x=-b/(2a). If a is negative, the max value of the function is f(-b/(2a)). if a is positive, the minimum value of the function is f(-b/(2a)).
f(x)=ax^2+bx+c
f(x)=x^2+4x+3
here a is positive so you are looking for a minimum,
x=-b/(2a)
x=-4/(2*1)
x=-2 ----> plug into f(x), f(-2)=(-2)^2+4(-2)+3=-1
minimum (-2,-1)
