Answer:
Step-by-step explanation:
(-1-1)/(8-0)= -2/8= -1/4
y + 1 = -1/4(x - 8)
y + 1 = -1/4x + 2
y = -1/4x + 1
Answer:
4a+13b+25
Step-by-step explanation:
Combine the opposite terms.
A = $ 861.69
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 5.5%/100 = 0.055 per year,
putting time into years for simplicity,
1 quarters ÷ 4 quarters/year = 0.25 years,
then, solving our equation
A = 850(1 + (0.055 × 0.25)) = 861.6875
A = $ 861.69
The total amount accrued, principal plus interest,
from simple interest on a principal of $ 850.00
at a rate of 5.5% per year
for 0.25 years (1 quarters) is $ 861.69.
Answer:
(2,-1)
Step-by-step explanation:
We know that,
Whenever a point lies on the graph of an equation, the coordinate pair of the point will be a solution to the equation.
As in this case,
(2,-1) lies on the lines of both Equation 1 and Equation 2. Hence, their common solution is (2,-1).
If the phone is 20% off, take 100-20 = 80.
Then find 80% of $179. The easiest way is to find the percent of a number is dividing that percentage by 100.
So, 80/100 = .8
.8 x 179 = $143.20.
