Y = -42 - 5
y = 3x - 2
Is (3, 7) a solution of the system?

The answer is below

Step-by-step explanation:

Given that:

y = 4x - 5

y = 3x - 2

This problem can be solved graphically by plotting the graphs of both lines, and the x and y coordinate of the intersection of both lines would give the solution to the problem. Also, the problem can be solved simultaneously by:

Step 1: subtract the second line equation from the first line equation to get

0 = x - 3

x = 3

step 2: Put x = 3 in equation 1 to get

y  = 4(3) - 5

y = 7

Therefore the solution = (x, y) = (3, 7)

5

step-by-step explanation:

soo this can be solve by using the formula:

f = p( 1 + i)^ n

where f is the future profit

p is the initial profit

i is the percent increase

n is the number of years

a . f = 30000 ( 1.05)^n

b. f = 30000 ( 1.05)^15

f = $62,368
