C. 3x-7=2x-5 solve for x, simplify

igomit [66]

3x - 7 = 2x - 5<em> add 7 to both sides</em>

3x = 2x + 2 <em>subtract 2x from borh sides</em>

Check:

L = 3(2) - 7 = 6 - 7 = -1

R = 2(2) - 5 = 4 - 5 = -1

L = R CORRECT! :)

For f (x) = 3x + 1 and g(x) = x^2 -6, find (f-g) (x)

natali 33 [55]

Answer:

Step-by-step explanation:

(f - g)(x) = f(x) - g(x), so

f(x) - g(x)

= 3x + 1 - (x² - 6) ← distribute by - 1

= 3x + 1 - x² + 6 ← collect like terms

= - x² + 3x + 7 → D

Solve for all values of y<br> in simplest form.<br><br> ∣y−12∣=16

Reil [10]

Answer:

$y=-4; y=28$

Step-by-step explanation:

The way I like to think about it, with absolute value meaning the distance is

"find which number are 16 apart from 12". Which means 28 (to the right) or -4 (to the left).

More formally, applying the definition of absolute value,

$|y-12|=16 \leftrightarrow y-12=\pm16\\y-12=-16 \rightarrow y=-4\\y-12=+16 \rightarrow y=28$
