A + (-5) = -12
First isolate your variable so move the -5 over (by adding 5 to both sides)
Then you will have a = -12+5
Simplify and you get A= -7
Answer:
y = –8x – 6 and y = 8x – 6
Step-by-step explanation:
-8x - 6 = 8x - 6
16x = 0
x = 0
y = 8(0) - 6 = -6
The only solution is (0,-6)
Answer:
a) 16/25
b)3/2
Step-by-step explanation:
all explaination is in picturw below
Restrictions for f and g: denominators can't be equal to zero.
1
• For f(x) = —— :
x²
x² ≠ 0
x ≠ 0
So the domain of f is
Dom(f) = {x ∈ R: x ≠ 0}
Dom(f) = R*
or using the interval notation,
Dom(f) = ]–∞, 0[ ∪ ]0, +∞[ .
________
5
• For g(x) = —— :
x²
Since g(x) = 5 · f(x), the restrictions for g are the same:
x² ≠ 0
x ≠ 0
So the domain of g is also
Dom(g) = {x ∈ R: x ≠ 0}
Dom(g) = R*
or using the interval notation,
Dom(g) = ]–∞, 0[ ∪ ]0, +∞[.
I hope this helps. =)

Answer:
$1,061.76
Step-by-step explanation:
(refer to attached handout)
For compound interest, you are given:
A = ? (need to find)
P = $1000
r = 3% = 0.03
n = compounded monthly = 12 times per year
t = 2 years
(substituting this into the formula)
A = P [ 1 + (r/n) ] ^(nt)
A = 1000 [ 1 + (0.03/12) ] ^[(12)(2)]
A = 1000 [ 1 + 0.0025 ] ^24
A = 1000 [ 1.0025 ] ^24
A = 1,061.76
