Answer:
5
Step-by-step explanation:
f(x) = 2x - 3x + 7
Plug in 2 every time you see an x within the equation: x = 2
f(2) = 2(2) - 3(2) + 7
f(2) = 4 - 6 + 7
f(2) = -2 + 7
f(2) = 5
Answer:
y =
x - 11
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (4, - 5 ) and (x₂, y₂ ) = (8, 1 )
m =
=
=
=
, then
y =
x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (8, 1 ) , then
1 = 12 + c ⇒ c = 1 - 12 = - 11
y =
x - 11 ← equation of line in slope- intercept form
Answer:
- payment: $413.93
- total repaid: $74,507.40
- interest: $22,507.40
Step-by-step explanation:
(a) The monthly payment A on principal P at monthly rate r for n months can be computed using ...
A = Pr/(1 -(1+r)^-n)
For P=$52000, r = .051/12 = 0.00425, n = 12*15 = 180, the payment is ...
A = $52000·0.00425/(1 -1.00425^-180) ≈ $413.93
(b) The total of 180 payments is ...
180 · $413.93 = $74,507.40
(c) The difference from the principal is the interest paid:
$74,507.40 -52,000 = $22,507.40
Answer:Hm
Step-by-step explanation:
The rules are


Let me show you why with a couple of examples: suppose we want to multiply

Since powers are just repeated multiplications, we have

Similarly, we have
