- 5x+7y=46
- Solve system of equations
- The intersection is (3,5)
The product is -648. This is because (-6)(4) is a negative product and (9)(3) is a positive product. A negative and a positive product equals a negative outcome. The third option is correct
Answer: No
Step-by-step explanation: If you mean 3^-2 it would be 0.111111111 repeating. 3^2 is 9 not -2
Answer:
The initial distance between Wade and Alexandra is 240ft.
They walk towards each other.
Alexandra walks twice as fast as Wade.
Now, because they are walking towards each other, when the distance walked by both of them equals 240 ft, they will meet.
Then:
if Wade walks z ft, Alexandra walks 2*z ft.
So we have the equation:
Distance that Wade walked + Distance that Alexandra walked = 240ft
z + 2*z = 240ft
3*z = 240ft
z = 240ft/3 = 80ft
They will meet when Wade walks 80ft.
