Identify the quadratic function(s). (Select all that apply.)8-5x = 4(3x - 1)
(48 + 272a-1)+1=0.
1 2y + 2/3y - 5) = 0
2bb-7)+b=0

Answers

For this case we have that by definition, a quadratic function is given by: $f (x) =ax ^ 2+ bx + c$

We evaluate the given equations:

Option A:

$8-5x =4(3x-1)\n8-5x=12x-4\n8 + 4 = 12x + 5x$

It is a linear equation!

Option B:

$(48 + 271a-1)+1 = 0\n48 + 271a-1+1 = 0\n48 + 271a = 0$

It is a linear equation!

Option C:

$12y + \frac {2} {3} y-5 = 0\n\frac {36y + 2y} {3} = 5\n36y + 2y = 15\n$

It is a linear equation!

Option D:

$(2b * b-7) +b = 0\n2b ^ 2-7 + b = 0\n2b ^ 2 + b-7 = 0$

It is a quadratic equation!

Answer:

Step-by-step explanation:

In the equation y=mx+b

b is the the value of y in the y-intercept

so change 2x+3y=12 into y=mx+b (Subtract 2x from both sides)

so 3y+2x-2x=12-2x

so 3y=-2x+12 (divide by 3)

y=-2/3x+4 so

Name two different numbers that round to 8.21 when rounded to the nearest hundredth

Answers

Answer:

The two different numbers are 8.211 and 8.209 that round to 8.21 when rounded to the nearest hundredth

Step-by-step explanation:

Given : Number 8.21.

To find : Name two different numbers that round to 8.21 when rounded to the nearest hundredth?

Solution :

To round to the nearest hundredth, we use the thousandths place to determine whether the hundredths place rounds up or stays the same.

We have top round such that number became 8.21.

So, There are two ways to pick the number

1) The thousandths place value is greater than or equal to 5 and hundredths place is 0 then it round to required number.

Example - 8.205,8.206,8.207,8.208,8.209

2) The thousandths place value is less than 5 and hundredths place is 1 then it round to required number.

Example - 8.211,8.212,8.213,8.214

Therefore, The two different numbers are 8.211 and 8.209 that round to 8.21 when rounded to the nearest hundredth

There's an infinite amount of numbers that round to 8.21 when rounded to the nearest hundredth, for example:

8.211
8.209
8.214
8.21145683204
etc...

Just pick whichever two numbers you like :)
