The answer after subtracting the following equation is x= -8/5
Step-by-step explanation:
- -2x+7y=10 ----- eq(1) , 3x + 7y =2------ eq(2)
- subtracting eq 2 from eq 1 we get

Answer:
Option D: g = 7 and h = 3
Step-by-step explanation:
The polynomial is;
8x² – 8x + 2 – 5 + x
Simplifying this gives;
8x² - 7x - 3
If this is simplified to 8x² – gx – h
Thus, by comparison of terms;
– gx = - 7x
-x will cancel out to get;
g = 7
Similarly, - h = - 3
Thus,h = 3
Therefore; g = 7 and h = 3
Answer:
The answer is:
58 km/hr
16.1 m/s
Step-by-step explanation:
406 km in 7h
x km in 1h
x= 1 x 406/7
x= 58 km/hr
58 km/hr ⇒⇒⇒⇒⇒⇒ 16.1 m/s
