A 2-column table with 8 rows. The first column is labeled x with entries negative 3, negative 2, negative 1, 0, 1, 2, 3, 4. The

second column is labeled f of x with entries negative 2, 0, 2, 2, 0, negative 8, negative 10, negative 20. Which could be the entire interval over which the function, f(x), is positive? (–∞, 1) (–2, 1) (–∞, 0)

Answer:

Choice B.

Step-by-step explanation:

Given the reported values:

x        f(x)

-3       -2

-2        0

-1         2

0         2

1          0

2        -8

3        -10

4        -20

We must locate the interval where f(x) is greater than zero.

The table shows f(x) is negative for x values less than -2 and greater than 1.

Between x = -2 and x = 1, f(x) takes positive values. Thus, the interval where f(x) is positive is (-2, 1).

Hence, the correct choice is B.

12x+7<−11 AND5x−8≥4012
Svet_ta [4341]

Answer:

No solution

Step-by-step explanation:

Given: 12x+7 and  5x-8\geq 40

Handle each inequality separately.

12x+7              Utilizing the subtraction property of inequalities

12x

12x

x

x

and

5x-8\geq 40               Utilizing the addition property of inequalities

5x\geq 40+8

5x\geq 48

x\geq \dfrac{48}{5}

Thus, the solution to the combined inequality is the overlap of both solutions.

Refer to the attached image for the number line representation.

tester [3938]
The recipe uses x cups of white flower together with 6 cups of wheat flower.

Therefore, the combined quantity of flower equals x+6

If y represents that combined amount, the equation to write is:
y=x+6

Constraints are as follows:
y can only be \geq 6

Note that if y = 0 then x would have to be -6, which is not possible.
