-7 is the missing exponent
Answer:
6.49 × 10⁷ years
Step-by-step explanation:
For Dinosaurs
Dinosaurs have been extinct for about 6.5×10 exponent seven years
6.5 × 10⁷ years
For Neanderthals
Neanderthals have been extinct for about 3.0×10 exponent four years
= 3.0 × 10⁴ years
How many longer is calculated by Subtraction
6.5 × 10⁷ years - 3.0 × 10⁴
= 64970000 years
= 6.49 × 10⁷ years
The answer of y+y+-10x is 2y-10x
Answer:
Blank 1: x
Blank 2: 2x
Blank 3: 2x-16
Blank 4: 12
Blank 5: 16
Blank 6: 2
Blank 7: 14
Blanks 8-10: at least 14
Blank 11: negative
Blank 12: flip
Blank 13: 2m
Blank 14: money
Blank 15: spent
Step-by-step explanation:
I believe these are the correct answers. I'm not so sure about Blank 12, 14 and 15, but otherwise I think these are correct. If you have any questions on any of them I'm happy to explain why. I hope this helps :D
I believe it is B because the y intersect is +6 and they slope is going down so it is -2
