A = p + prt
The above equation can be solved for “r” in such a
way.
Subtract “p” from both sides;
A – p = p + prt – p
A – p = prt
Divide both sides by “p” and “t”;
A/pt – p/pt = prt/pt
A/pt – 1/t = r
Or
<span>r = A/pt – 1/t</span>
Answer:
3x² - 2x - 6
Explanation:
We are given that:
f (x) = 3x² - 2
g (x) = 2x + 4
We want to find the value of (f - g)(x), this means that we will simply subtract g (x) from f (x) as follows:
(f - g)(x) = f (x) - g (x)
(f - g)(x) = 3x² - 2 - (2x + 4)
(f - g)(x) = 3x² - 2 - 2x - 4
(f - g)(x) = 3x² - 2x - 6
Hope this helps :)
Answer:
x = 8
Step-by-step explanation:
3 (x-2) = 22 – x
⇔3x -6 = 22 –x
⇔3x + x = 22 + 6
⇔4x = 32
⇔x = 8
