Help me please......!!!!

Answer: B

Step-by-step explanation:

The range of a function is the set of all possible values for the function's dependent variable. In this case, that variable is y, so we can look at the graph to observe what possible y-values fit in the range.

There are no y-values below -1 on the chart, and the function goes upwards to infinity, so the correct answer is B, y is greater than or equal to -1.

write the product of the expression 5^4 * 5^-7 using a positive exponent, then write the product using a negative exponent

pav-90 [236]

Answer with positive exponent = $\left(\frac{1}{5}\right)^3$ or $\frac{1}{5^3}$

Answer with negative exponent = $5^{-3}$

===========================================================

Explanation:

The rule we use is

$a^b*a^c = a^{b+c}$

If we multiply two exponential expressions with the same base, then we add the exponents.

The base for each is 5. The exponents 4 and -7 add to -3.

This means

$5^4*5^{-7} = 5^{4+(-7)} = 5^{-3}$

To convert to a positive exponent, we apply the reciprocal to the base. We go from 5, aka 5/1, to 1/5.

So, $5^{-3} = \left(\frac{1}{5}\right)^3 = \frac{1^3}{5^3} = \frac{1}{5^3}$

What is the slope of the line that passes through the points (-4,-2) and (-4,-22)? Write your answer in simplest form.

Anuta_ua [19.1K]

Answer:

$20x - 4 = 0$

Step-by-step explanation:

$\frac{y - y1 }{y2 - y1} = \frac{x - x1}{x2 - x1} \\ x1 = - 4 \\ y1 = - 2 \\ x2 = - 4 \\ y2 = - 22$

$x2 = - 4 \\ y2 = - 22$
