Alright, so plugging it in, we get 2(-4)^2=2(2)^4+3^2-(-4)^2+2^4. Use PEMDAS with parenthesis and exponents to then get (2)(16)+9-16+16. Multiplying 1 and 16, we get 32+41-16+16=73
Find the slope: m=(19.00-13.60)/(2003-1998)=1.08
so we have y=1.08x +b
next, use the point (2003, 19.00) to find b:
19.00=1.08*2003 +b =>b=-2144.24
so the equation is y=1.08x-2144.24
Answer: Last answer
Step-by-step explanation:
Answer:
Michael is 21 years old while Jean is 7 years old.
Step-by-step explanation:
Given that Micheal is three times as old as Jean, but in seven years he will be twice old as she will be, to determine how old are they both at this time, the following calculation must be performed:
M = 3J
M + 7 = 2J + 7
7 = 1/3
7 x 3 = 21
21 + 7 = 28
7 + 7 = 14
21 / 7 = 3
28 / 14 = 2
Therefore, Michael is 21 years old while Jean is 7 years old.
It would be answer 3. sorry if it’s wrong
