Answer:
a = -14
Step-by-step explanation:
f(a) = -43
3a - 1 = -43
3a = -43 + 1
3a = -42
a = -42/3
a = -14
Answer:
Step-by-step explanation:
y -
= m( x -
) point - slope form of linear equation ;
y = mx + b slope-intercept form of linear equation, (0, b) are coordinates of y-intercept ;
<em>(b).</em> y - 3 = - 7(x - 8)
<u><em>y = - 7x + 59</em></u>
<em>(c).</em> y - (- 2) =
[ x - ( - 7)] ⇔ y + 2 =
( x + 7)
<u><em>y = </em></u>
<u><em> x + </em></u>
<u><em> </em></u>
<em>(d).</em> <u><em>y = - </em></u>
<u><em> x + 9</em></u>
Answer:
This question kind of illogical, if it's a one before the other kind.
Explanation:
Computer scince priniples, especially AP, will most likely involve some equations and potential coding. Most of the numbers and coding will most likely involve some level of calc. Even if they didn't, this class indicates that you most likely wish to get into a form of computer science as a career, perhaps computer animation or engineering. Regardless of the path, some understanding of calculus would be immensly helpful in the future if not now. At the end of the day, it really is your call and not some people on a homework helping site, but I would choose precalc.
Note: Im not you, I don't know what you want in life, i'm just guessing here. Regardless, I believe you'll make the best descision my friend :).
For the answer to the question above,First 2+3x= 18
3x= 18-2
3x= 16
X= 16/3
Let's try to check: 2+ 3(16/3)= 18
2 + 16= <u><em>18</em></u>
The answer is for this question is <u><em>16/3 or 5 1/3.</em></u>
I hope my answer helped you. Have a nice day!

Answer:
Option c
or ![y \leq 21](https://tex.z-dn.net/?f=y%20%5Cleq%2021)
Step-by-step explanation:
The absolute value is a function that transforms any value x into a positive number.
Therefore, for the function
x> 0 for all real numbers.
Then the inequation:
has two cases
if
(i)
if
(ii)
We solve the case (i)
![y \leq 9 + 12\\y\leq21](https://tex.z-dn.net/?f=y%20%5Cleq%209%20%2B%2012%5C%5Cy%5Cleq21)
We solve the case (ii)
![-y +9 \leq 12\\-y \leq 12-9\\y \geq -3](https://tex.z-dn.net/?f=-y%20%2B9%20%5Cleq%2012%5C%5C-y%20%5Cleq%2012-9%5C%5Cy%20%5Cgeq%20-3)
Then the solution is:
or ![y \leq 21](https://tex.z-dn.net/?f=y%20%5Cleq%2021)
