IgorC [24]

Answer:

$y \: intercept = - 1 \frac{1}{2}$

Step-by-step explanation:

The y intercept form for the equation of a line is

$y = mx + c$

You should note that <em>c</em> represents the y-intercept of the line (where the line touches the y-axis)

$y = mx + c \\ \\ we \:were\: given \:the \:equation \:y = x - \frac{3}{2} \\ \\ therefore \: the\: value \:of \:c \:is\: - \frac{3}{2} \:or -1 \frac {1}{2}$

The expression (q16)(q−5)2 is equivalent to qn. What is the value of n? 42 22 -160 13

Lelu [443]

Answer:

Step-by-step explanation:

In order to get one of the answer choices, it appears we need to interpret your input as ...

$(q^{16}q^{-5})^2 = (q^{16-5})^2=q^{11\cdot 2}=q^{22}$

The value of n is 22.

The applicable rules of exponents are ...

(a^b)(a^c) = a^(b+c)

(a^b)^c = a^(bc)
