Write an expression that shows how to use the halving and doubling strategy to find 28x50
Halving strategy means we divide by 2
Doubling strategy means we multiply by 2
We apply halving strategy for 28 and doubling strategy for 50
Half of 28 is 14
Double of 50 is 100
So 14 * 100 = 1400
Now we check with 28 * 50
28 x 50 = 1400
So required expression is
Answer:
<u>-1/5</u> would be the exact form
Step-by-step explanation:
The decimal form would be <u>-0.2</u>
The line with the arrows is where y=-3 is
That represents exponential growth because we are multiplying by 2.1 every time. Since you are multiplying by a number greater than 1 that means that the number is getting bigger as x gets bigger. This means that we have exponential growth.
Answer:
y=1/5x+7/5
