Keith_Richards [23]3 years ago
7 0

Answer:

  {x| x≤ 1/2 or x ≥ 3/4}

Step-by-step explanation:

The values of x that make the factors zero are 3/4 and 1/2. The product of these factors will be positive when both factors are negative (for x < 1/2) or when both factors are positive (x > 3/4). The matching answer selection is the third one.

What is the value of 7 ^−3 ^ −1 for = −2 and = 4?
andrey2020 [161]

Answer:

d. −7/32

Step-by-step explanation:

The expression that we have to evaluate in this problem is:

7x^{-3}y^{-1}

We have to evaluate this expression for:

x = -2

y = 4

We start by rewriting the expression by rewriting it using the following:

a^{-n}=\frac{1}{a^n}

So the expression can be rewritten as

7x^{-3}y^{-1}=\frac{7}{x^3 y}

Now we observe that:

(-2)^3=(-2)(-2)(-2)=-8

Therefore, by substituting x = -2 and y = 4 into the expression, we find:

\frac{7}{(-2)^3\cdot 4}=\frac{7}{-8\cdot 4}=-\frac{7}{32}
