Answer:
Step-by-step explanation:
we have : lines 2 x + 4 y = 0 and 2 x + y = 10
Let ,
2 x + 4 y = 0............. (1)
2 x + y = 10...............(2)
solve these equations for x and y
Now subtract (2) from (1) ,we get
3y=-10
⇒y = 
Put the value of y in (1) , we get
2x+4() = 0
⇒2x= 
⇒x=
∴ Point of intersection is 
.
Hence,the x-coordinate of that point is .
Answer:
60 in³
Step-by-step explanation:
Prism A is 2×3×5 which is 30in³
Prism B is 2 times the height, which means it is 4×3×5 which is 60
Real life problem for quadratic equation:

Answer:
14 miles
Step-by-step explanation:
Assuming each horse was only ridden once
then a total of 13 horses were ridden for a total of 182 miles
182 miles
/ 13 horses = 14 miles horse
Of course, if each horse was ridden more than once before being replaced the distance between replacements could be reduced.
Note that the fact that there were 3 riders is irrelevant.
