Answer:

x = - 3

Step-by-step explanation:

2x - 10 + 6 = 7x - 7 - 2x + 12

2x - 4 = 5x + 5

- 5 - 4 = 5x - 2x

-9 = 3x

x = - 9/3

x = - 3

Given g of x equals cube root of the quantity x minus 3, on what interval is the function positive?
zmey [24]

The function is positive when x is larger than 3, then the interval in where the function is positive is: (3, ∞)

<h3>on what interval is the function positive?</h3>

The function is positive when g(x) > 0.

Then we need to solve:

∛(x - 3) > 0

We can directly remove the cubic root, because it does not affect the sign of the argument, then:

x - 3 > 0

x > 3

The function is positive when x is larger than 3, then the interval in where the function is positive is: (3, ∞)

Which ordered pair is a solution to the system of equations?
tatyana61 [14]
2x - y = -2 . . . (1)
5x - 2y = -7 . . . (2)
From (1), y = 2x + 2 . . . (3)
Putting (3) into (2), gives:
5x - 2(2x + 2) = -7
5x - 4x - 4 = -7
x - 4 = -7
x = -7 + 4 = -3
y = 2(-3) + 2 = -6 + 2 = -4.

Therefore, the required answer is (-3, -4)

mylen [45]

Answer:

12 pints

Step-by-step explanation:

There are 24 students & each one gets 1 cup, so you will need 24 cups total.  There are 2 cups in a pint.  You divided the 24 cups you need by 2 cups in a pint to get the answer of 12 pints.

You can double check:  12 pints converted to cups (2 cups in a pint) is 12 x2 = 24 cups
