Converting From Vertex To Standard Form Plzz Help ;(

Answers

Answer 1

Answer:

x²-4x+7

-x²-6x-12

Step-by-step explanation:

1.) the first thing we do is expand the exponent (or mulitply  (x-2)(x-2) the images below will show you how to do that

We get x²-4x+4 and then just need to add three

x²-4x+7

2.)

We do the same thing (expand the exponent) and get x²+6x+9

which means so far we have

-(x²+6x+9)-3

carry out the negative sign and subtract 3

-x²-6x-12

the answer is none the right answer would be x>= -37/3
All you have to do is put in one of the numbers given and put it in the inequality as x. For example, in the picture you can see that I put in each of the numbers as x for the equations and checked which ones came out as false or true. The ones that came out as true are the correct answer. So the answer is 8 and 2.

Answer:

  put the value into the equation and do the arithmetic

Step-by-step explanation:

As with any checking, you put the value where the variable is and do the arithmetic.

  7(2x +5) = 11x -9 -x

For x = -11

  7(2(-11) +5) = 11(-11) -9 -(-11)

  7(-22 +5) = -121 -9 +11

  7(-17) = -119

  -119 = -119

The value x = -11 makes the equation true.

Answer:

Step-by-step explanation:

The future value of the account is given by the formula ...

  A = P(1 +r/12)^(12t) . . . . principal P invested at rate r for t years

Solving for t, we find ...

  A/P = (1 +r/12)^(12t) . . . . . . . . . . . divide by P

  log(A/P) = 12t·log(1 +r/12) . . . . . . take logs

Divide by the coefficient of t, then fill in the numbers.

  t = log(A/P)/(12·log(1 +r/12)) = log(202800/93000)/(12·log(1 +.068/12))

  t ≈ 11.497

It will take about 11 years for the account balance to reach the desired amount.

the width if a rectangular room is 1 less than twice the length if the perimeter is 196 feet how long is the length

Answers

Answer:

l = 33 feet

Step-by-step explanation:

Let length be l.

Width, b = 2l-1

Perimeter of the room, P = 196

We know that the perimeter of the rectangle is given by :

P = 2(l+b)

196=2(l+2l-1)

98=3l-1

Adding 1 both sides.

98+1=3l-1+1

3l=99

l = 33 feet

So, the length of the room is 33 feet.

Find x y and ABHG for brainliest

Answers

Answer:

because AB//EF//CD, using thales theorem in ABEF, we have:

[tex]\frac{12}{21}=\frac{15}{y}\\\\<=>y=\frac{15.21}{12}=26.25[/tex]

we also have: CD//EF//GH => using thales theorem in CDGH:

[tex]\frac{21}{x}=\frac{y}{10}\\\\<=>x=\frac{210}{y}=\frac{210}{26.25}=8[/tex]

with y = 26.25 => AB = 26.25 - 14 = 12.25

        x = 8 => GH = 5.8 - 3 = 40 - 3 = 37

+) the perimeter of ABHG = AB + AC + CE + GE + GH + HF + DF + BD

= 12.25 + 12 + 21 + 8 + 37 + 10 + 26.25 + 15

= 141.5
