What expressions are equivalent to z+(z+6)

It would be the number 1 because this is using distributive property. You’re adding the z to both z and 6 separately.

It wouldn’t be number 2 because there’s only one 6. You don’t know the values of the z so you can’t put another 6. It wouldn’t be number 3 because the 30 comes out of nowhere. There’s only one known value in the equation.

17x - 6 + 3x - 5 = x + 11 + 4x<br> simplify
densk [106]

Answer:

The answer is x= 22/15=1,47

Step-by-step explanation:

We put in one member the X and in the other the whole numbers:

17x - 6 + 3x - 5 = x + 11 + 4x

17x +3x -x-4x= 11+6+5

15x = 22

x= 22/15

Expression for the quotient of b divided by the difference of two minus 3
uysha [10]

Answer:

The required expression is

                                     \frac{b}{2 - 3}  = - b

Step-by-step explanation:

 

Difference of two minus three = 2-3

Quotient of b divided by the difference of two minus three is

                                             \frac{b}{2-3} = \frac{b}{-1} = - b

Therefore, the required expression is

                                                  \frac{b}{2-3}  \ \ \ \ \ \ \ \ or \ \ \ \ \ \ \ \  - b

Can you help me solve. My teacher got those answers but I don’t know how.
valina [46]

Answer:

Your teacher is correct.

Step-by-step explanation:

Common knowledge about coordinates:

The first number in a coordinate is the "x coordinate".

The second number is the "Y coordinate".

The X axis is the horizontal line.

The Y axis is the vertical line.

The origin is the middle of the two axis's.

For A, the x coordinate is -4. You go right on the horizontal line because it is a negative number. The y coordinate is 4, so you go up from -4 to 4 because it is a positive number. there, you'll get your coordinate (-4 , 4).

For B, because the x coordinate is 0, you don't move at all, and you stay on the x origin. The y coordinate is 6, so you go up from the origin to 6. There, you'll have (0, 6).

C is pretty self explanatory if you understand the concept.

Solve for x<br>6x²+2x-12​
dem82 [27]

Answer:

Step-by-step explanation:

Solving for x means you have to factor. First factor out the GCF of 2 to get:

2(3x^2+x-6) and now we'll factor using the regular old method of ac and then factoring by grouping. In our polynomial, a = 3, b = 1, c = -6. Therefore, a times c is 3 * -6 which is -18. We need some combinations of the factors of 18 that will add to give us 1, the b term in the middle. The factors of 18 are:

1, 18

2, 9

3, 6 and that's it. Hm...it seems that won't work, so let's throw this into the quadratic formula, going back to the original and a = 6, b = 2 and c = -12:

x=\frac{-2+/-\sqrt{2^2-4(6)(-12)} }{2(6)} and

x=\frac{-2+/-\sqrt{4+288} }{12} and

x=\frac{-2+/-\sqrt{292} }{12} and

x=\frac{-2+/-\sqrt{4*73} }{12} and

x=\frac{-2+/-2\sqrt{73} }{12} which finally simplifies to

x=\frac{-1+/-\sqrt{73} }{6} No wonder that didn't factor using the traditional method of factoring! We could have found that out by finding first the value of the discriminant, but oh well!
