8x - y = 54
8x + 2y = 60
subtracting, we get -3y = -6
y = 2
x = 7
Answer is (c) (7,2)
Answer:
A = $45948
Step-by-step explanation:
Given the following data;
Principal = $8000
Interest rate = 6% = 6/100 = 0.06
Time = 30 years
To find the future value, we would use the compound interest formula;
Where;
A is the future value.
P is the principal or starting amount.
r is annual interest rate.
t is the number of years for the compound interest.
Substituting into the equation, we have;

A = $45948
Answer:
-(x-8)*(x+7)
Step-by-step explanation:
Use the commutative property
-× to the power of 2 + x+ 56
-x to the power of 2 + 8x-7x+56
-xx(x-8)-7x+56
-x*(x-8)-7(x-8)
factor out -(x-8)
-(x-8)*(x+7)
hope it helps!!
Sorry, I didn't read the question fully. I don't know how to do this. Please disregard my previous answer.
Hey! The most intuitive way I've been explained the idea of subtracting negative numbers is in terms of debts. <em>Subtracting</em> a debt from your bank account has the effect of <em>adding </em>money to it. Imagine you had $10 in your account, but you owed $8 in debt; your current balance would show $2 in your account. If you <em>took away that debt</em>, though, you'd be back up to $10. If we imagine your funds as positive numbers and your debts as negative numbers, we could express taking away that debt as:
2 - (-8) = 10
Hope that makes a little more sense!
