Can someone please tell me if i am right?

Answers

Answer 1

Answer: Second one is correct, that is an identity.

Third one is a contradiction:
6x - 15 = 3 * (2x - 6) ------> 6x - 15 = 6x - 18

Fourth one:
5x - 3 * (x - 4) = 2 * (x - 6) ---> 5x - 3x + 12 = 2x - 12 ---> 2x + 12 = 2x -12
So this is a contradiction as well.

How to write 1.23,1.2,2.31,3.2 from least to greatest

Answers

from least to greatest it would be: 1.2, 1.23, 2.31, 3.2 I believe hope that helped

It's pretty simple actually, it's least to greatest? Then lets start out with the least, which means closest to 0:
1.2
1.23
Since 1.23 has more numbers in it, it is greater than 1.2, because 1.2 could also be written out as 1.20 and that is less than 1.23.

Now lets go with the greatest:
2.31
3.2
It's obvious 3.2 would be the greatest, so therefore:

1.2, 1.23, 2.31, 3.2
is from least to greatest.

Hope this helps!

If 12% is 36 then what is 100%

48/72 you take the numbers x 2

C, cuz 3 times 8= 24, but 4 times 8 doesn't = 36 it equals 32

Identify the coefficients and the constants from the following expression.

3+4x-y+5x-2

Answers

The leading coefficients are the numbers infront of the variable which are 1 and 4

The constants are the numbers that do not have a variable which are 3 and -2

4x+5x=9x, 3-2=1

9x-y+1

coefficients are 9 and -1, the constant is 1.

Solve with the quadratic formula
4×^2×+1=0

Answers

Answer:

Either x = + i/2 or x = i/2 is the solution for the given quadratic equation.

Step-by-step explanation:

Here, the given quadratic equation is: $4x^2 + 1 = 0$

Now, comparing the given equation with standard Quadratic Form, $ax^2 + bx + c = 0$

we get,a = 4, b =0 and c = 1

Now, the Quadratic Formula is given as:

$x = (-b \pm √(b^2 - 4ac) )/(2a)$

So, here the solution for the given expression is:

$x = (0 \pm √((0)^2 - 4(4)(1)) )/(2(4)) = x = (0 \pm √(-16) )/(8)\n\implies x = (0 \pm4i)/(8)\n\implies x = (0 + 4i)/(8) = (i)/(2) \nor, x = (0 - 4i)/(8) = (-i)/(2)$

Hence, either x = + i/2 or x = i/2 is the solution for the givenquadratic equation.
