What is the x-value of the solution of the system of
Nady [450]

Answer:

x = -1, y = -4

Step-by-step explanation:

Let's solve our system of equations by substitution.

y = 5x + 9y = −x + 3

Step: Solve = 5x + 9 for y:

y = 5x + 9

Step: Substitute 5x + 9 for y in y = −x + 3:

y = −x + 3

5x + 9 = −x + 3

5x + 9 + x = −x + 3 + x (Add x to both sides)

6x + 9 = 3

6x + 9 + −9 = 3 + −9 (Add -9 to both sides)

6x = −6

6x/ 6 = −6/6(Divide both sides by 6)

x = −1

Step: Substitute −1 for x in y = 5x + 9:

y = 5x + 9

y = (5)(−1) + 9

y = 4(Simplify both sides of the equation)

So our answers are y = -4 and x = -1.

Edgar accumulated $11,000 in credit card debt. If the interest rate is 30% per year and he does not make any payments for 3 year
Gennadij [26K]

Answer:

= 1.38778e-141 which makes interest a large amount 139 million and 108 hundred thousand and fourhundred and four.

Step-by-step explanation:

The equation is A= P 1+ r/n ^nt

So we input for A = (11000) x 1.30/11000 ^ 36 x 3

= 1.38778e-141 which makes interest a large amount 139 million and 108 hundred thousand and fourhundred and four.

The formula used in the compound interest calculator is A = P(1+r/n)(nt)

A = the future value of the investment

P = the principal investment amount

r = the interest rate (decimal)

n = the number of times that interest is compounded per period

t = the number of periods the money is invested for

. The land area of Charlotte, NC is approximately 3 x 102 square miles.
lidiya [134]

Answer:

Option A

Step-by-step explanation:

Land area of Charlotte, NC = 3\times 10^2 square miles

Scale to be used,

1 square miles = 6.4\times 10^2 square acres

By this scale,

3\times 10^2 square miles = (6.4\times 10^2)\times(3.2\times 10^2) square acres

                                  = (6.4\times 3)\times 10^{2+2}

                                  = 19.2\times 10^4 square acres

                                  = 1.92\times 10^5 square acres

Therefore, Option A will be the correct option.
