The car travelled 200 meters
20 m/s times 10 = 200 m in 10 s
Because it doesn't give a number grade, I took the mid=point of each letter grade which I came up with 850, then divided it by 10 (number of grades recorded) came up with an 85 average.
Answer is D.
Because;
The first equation = the second equation
<span>4x – 5y = –18 (1st)
3x + 2y = –2 (2nd)
Multiply 1st equation by 2 and 2nd equation by 5
</span>4x – 5y = –18 (1st) (mul. 2)
3x + 2y = –2 (2nd) (mul. 5)
8x - 10y = - 36
15x + 10y = - 10
-----------------------add
23x = - 46
x = -2
3x + 2y = –2
3(-2) + 2y = –2
-6 + 2y = -2
2y = 4
y = 2
(-2,2)
answer
<span>(–2, 2)</span>
