The first thing we must do for this case is to define variables.

We have then:

x: unknown number

We now write the equation that models the problem:

$2x + 8 = x + 12$

From here, we clear the value of x.

$2x - x = 12 - 8\\x = 4$

The unknown number is equal to 4.

Answer:

The number is:

$x = 4$

$x-my\ number\\\\2x+8=x+12\ \ \ \ \ \ |subtract\ 8\ from\ both\ sides\\\\2x=x+4\ \ \ \ \ \ |subtract\ x\ from\ both\ sides\\\\\boxed{x=4}\\\\Answer:My\ number\ is\ 4.$

1/2 (3/2 y + 1/3) = -1/2 (y- 5/2)

dem82 [27]

1/2 [ (3/2)y + 1/3] = -1/2 [y-5/2]

(3/2)y + 1/3 = -(1/2)y + 3

(3/2 + 1/2)y = 3 - 1/3

2y = 8/3

y = 4/3

y = 1.33

When simplified and written in standard form, which quadratic function is equivalent to the polynomial shown?

mars1129 [50]

Answer:

2c^2 - 2c - 3

Step-by-step explanation:

Next time, please share the answer choices. Thank you.

Group together the 'c' terms in 2 + 7c – 4c2 – 3c + 4:

2 + 4c and -4c^2 + 4 Then we have:

-4c^2 + 4c + 6

We should reduce this by factoring -2 out of all three terms:

2c^2 - 2c - 3 This is the desired quadratic in standard form.

Write 7x^2 -4 + 6x^3 -4x -x^4 in standard form

Nata [24]

-x⁴+ 6x³- 7x²- 4x - 4

Order from least to greatest exponent (the variable, which is x in this case, is always first by the way in terms of order, then integers). This point of this problem is essentially to just rearrange the original equation.
