24000000. 1000000*24= 24000000, therefore, a million days ago in hours would be 24000000.

Find the following when a = -1, b = 2, c = -1/4<br> (4b - 3)/(2a) -1

Katena32 [7]

We substitute the given into the equation
given: a=-1, b=2, c= $\frac{-1}{4}$
=( $\frac{4b-3}{2a}$ -1
= $\frac{4(2)-3}{2(-1)}$ -1
= $\frac{8-3}{-2}$ -1
= $\frac{5}{-2}$ -1
to continue, we can either find a common denominator or change the fraction to decimal.
Fraction to Decimal:
$\frac{5}{-2}$ =-2.5
Equation=-2.5-1=-3.5
OR Common Denominator:
= $\frac{5}{-2}$ $\frac{-1}{1}$ × $\frac{-2}{-2}$ (denominator should be -2=common)
= $\frac{5}{-2}$ + $\frac{2}{-2}$
= $\frac{7}{-2}$
which also = to -3.5

Match the circle equations in general form with their corresponding equations in standard form. x2 y2 − 4x 12y − 20 = 0 (x − 6)2

frosja888 [35]

The equation given is matched with the respective vertex forms.

<h3>What is the standard Equation for a circle ?</h3>

The standard equation for a circle is given by

(x-h)² + (y-k)² = r²

The equation given in the question are

x² + y² − 4x + 12y − 20 = 0

(x − 6)² + (y − 4)² = 56

x² + y² + 6x − 8y − 10 = 0

(x − 2)² + (y + 6)² = 60

3x² + 3y² + 12x + 18y − 15 = 0

(x + 2)² + (y + 3)² = 18

5x² + 5y² − 10x + 20y − 30 = 0

(x+3)² + (y-4)² = 35

2x² + 2y² − 24x − 16y − 8 = 0

(x-1)² + (y+2)² = 11

The first equation is

x² + y² − 4x + 12y − 20 = 0

It can be written ad

x² -4x + 4 - 4 +y²+12y +36-36 -20 = 0

(x-2)² +(y+6)²= 60

The second equation is

x² + y² + 6x − 8y − 10 = 0

x² +6x +9-9 +y² -8y +16-16 -10 = 0

(x+3)² + (y-4)² = 35

The third equation is

3x² + 3y² + 12x + 18y − 15 = 0

(x + 2)² + (y + 3)² = 18

The fourth equation is

5x² + 5y² − 10x + 20y − 30 = 0

(x-1)² + (y+2)² = 11

The fifth equation is

2x² + 2y² − 24x − 16y − 8 = 0

(x − 6)² + (y − 4)² = 56

coldgirl [10]

Answer:

Can u send picture with it pls so i can figure it out?

What are the two shapes

Step-by-step explanation:

rectangle: length times width

triangle: base times height divided by 2

parallelgram: Base times height

square: side times side

*If you get it right then follow me on roblox: Supertasticgg

and sub to Flamingo

ANd almost forgot trapezoid: base 1 + base 2 times by height then divide with 2

I am stuck on this question of knowing how to break it down to get the answer

maksim [4K]

3 x 3 - ( (-1)^2 - 2)^2

Start evaluating the one in the most inner bracket:
3 x 3 - ( (-1)^2 - 2)^2
= 3 x 3 - (1 - 2)^2

There is one more bracket, so we do what is in the bracket:
3 x 3 - ( (-1)^2 - 2)^2
= 3 x 3 - (1-  2)^2
= 3 x 3 - (-1)^2
= 3 x 3 - 1

Between x and -, we do the x first:
3 x 3 - ( (-1)^2 - 2)^2
= 3 x 3 - (1-  2)^2
= 3 x 3 - (-1)^2
= 3 x 3 - 1
= 9 - 1

Then we do the -:
3 x 3 - ( (-1)^2 - 2)^2
= 3 x 3 - (1-  2)^2
= 3 x 3 - (-1)^2
= 3 x 3 - 1
= 9 - 1
= 8
