Answer:

$-\frac{1}{21}$

Step-by-step explanation:

The opposite of -2\3 is 2\3

-5\7 + 2\3

Least common multiple of 7 and 3 is 21. Convert -5\7 and 2\3 to fractions with denominator 21.

-15\21 + 14\21

Sinse -15\21 and 14\21 have the same denominator, add them by adding their numerators.

$\frac{-15+14}{21}$

Add −15 and 14 to get −1.

-1\21

Answer:

Step-by-step explanation:

y = -2x+5

slope of line is -2.

slope of parallel to line is also -2

point-slope equation for line of slope -2 that passes through (-5,3):

Complete the table of inputs and outputs for the given function g(x) = 3 - 8x

NeX [460]

Answer:

See Explanation

Step-by-step explanation:

<em>The question is incomplete as the input and output values are not given. However, the question can still be solved by assuming both values</em>

Given

$g(x) = 3 - 8x$

In this case;

x represents the input while g(x) represents the output

Now, assume x = 2; Determine the output.

Here we simply substitute 2 for x in the above expression

i.e.

$g(x) = 3 - 8x$ becomes

$g(2) = 3 - 8(2)$

$g(2) = 3 - 16$

$g(2) = -13$

Similarly, if x = 5

$g(5) = 3 - 8(5)$

$g(5) = 3 - 40$

$g(5) = -37$

Also, let's assume g(x) = -21; Determine the input

$g(x) = 3 - 8x$ becomes

$-21 = 3 - 8x$

Solve for x

$-21 - 3 = -8x$

$-24 = -8x$

$x = \frac{-24}{-8}$

$x = 3$
