Answer:
Step-by-step explanation:
To solve this you take 0 as the starting number, he lost 20 points so you subtract 20 and get -20. Next add 15 points. You then get -5. Then he got another answer right so you add 35 to -5. It the same if you say 35-5. Which gives you 30. So your answer is 30
Answer:
y = -2·(1/2)^x
Step-by-step explanation:
The ratio of one table entry to the one before is ...
(-2)/(-4) = 1/2
so this is the <em>growth factor</em>.
The <em>multiplier</em> is the value of y when x=0, which is -2. So, the equation is ...
y = (multiplier)·(growth factor)^x
y = -2·(1/2)^x
_____
This can also be written using a negative exponent:
y = -2·2^(-x)
9+×(5)=7 and thats ur answer. more than equals to adding and five is there just to be there so just multiply it in parentheses
