I believe the answer is y=2x−5 Im not quiet sure

Answer:

y=2x-5

Step-by-step explanation:

Slope intercept from has 4 parts, a y, an x, an m, (slope in front of x) and a b (y-int).

We must first isolate the 1y to the front of the equation by adding 1x to each side.

This gives us our final answer of (1) y = 2x-5

years at a rate of 6.5% per annum. Find the amount he will receive after 4 1/2

Answers

Answer:

12780

Step-by-step explanation:

The amount of money Alex would receive at the end of 41/2 years is ₹15,510.

The amount of money Alex would receive at the end of 41/2 years is the sum of the interest he would earn and the amount of money he deposited.

Interest = principal x time x interest rate

12,000 x 4.5 x 0.065 = 3510

The amount of money Alex would receive = 3510 + 12,000 = 15,510
