Answer:

2x - y - 5z

Step-by-step explanation:

Given

-[z - 3y - (3x - z - 2y) + 3z + 2y] - x =

Distribute the subtraction into the ()

-[z - 3y -3x + z + 2y + 3z + 2y] - x =

Move the terms around, <em>keeping</em> the sign with the term

-[z + z + 3z - 3y + 2y + 2y - 3x] - x =

Combine like terms

-[2z + 3z - 3y + 2y + 2y - 3x] - x =

-[5z - 3y + 2y + 2y - 3x] - x =

-[5z - y + 2y - 3x] - x =

-[5z + y - 3x] - x =

Distribute the subtraction into the []

-5z - y + 3x - x =

Combine like terms

- 5z - y + 2x

Reorder:

2x - y - 5z

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.

Use the method from the Example to approximate the solution to the equations below to two decimal places.
STALIN [3.7K]

Answer:

x = 3.85

Step-by-step explanation:

Given equation:

6ˣ = 1,000

now,

on taking log both sides, we get

⇒ log(6ˣ) = log(1,000)

or

⇒ log(6ˣ) = log(10³)

now we know the property of log function that

log(aᵇ) = b × log(a)

thus, applying the above property, we get

⇒ x × log(6) = 3log(10)

or

⇒ x × log(2×3) = 3log(10)

now,

we have another property of log function as":

log(A) = log(A) + log(B)

therefore,

x × [log(2) + log(3)] = 3log(10)

also,

log(10) = 1

log(2) = 0.3010

log(3) = 0.4771

Thus,

⇒ x × [0.3010 + 0.4771 ] = 3 × 1

or

⇒ x × 0.7781 = 3

or

⇒ x = 3.85

Write the equation of the parabola in vertex form with vertex at (2,-5) and y intercept at -17.
jok3333 [9.3K]
<h3>Answer:</h3>

y = -3(x -2)² -5

<h3>Explanation:</h3>

The equation of a parabola with vertex (h, k) is given by ...

... y = a(x -h)² +k . . . . . . . for some vertical scale factor "a".

We can find the value of "a" by substituting the coordinates of a point that is not the vertex. Here, that point is the y-intercept: (0, -17).

... y = a(x -2)² -5 . . . . . initial form of the equation for the parabola

... -17 = a(-2)² -5 . . . . . substitute y-intercept values

... -12 = 4a . . . . . . . . . . add 5, simplify

... -12/4 = a = -3

The desired equation is ... y = -3(x -2)² -5.
