Answer:
x = 10
Step-by-step explanation:
8x - 13 = 5x + 17 (DE = EF)
8x - 5x = 17 + 13
3x = 30
x = 10
Answer:
If the equation is 3x^2+6y^2, when x=0 and y=2.
Then, 3(0)^2+6(2)^2=
So, 0+6(4)= 24
Therefore, the answer is 24.
Step-by-step explanation:
Your y-intercept would be (0,-15) and your x-intercept would be (-60,0)
Answer:
Her centripetal acceleration during the turn at each end of the track is 
Step-by-step explanation:
Total distance covered in one round , D= 400 m
Time taken to cover one round , T = 1 min 40 s = 100 sec
Speed of runner , 
Now centripetal acceleration is given by

where 


Thus her centripetal acceleration during the turn at each end of the track is 
Answer:
A
Step-by-step explanation:
A is the only one that passes the vertical line test
(the vertical line test is when you can draw a line anywhere on the graph and it only touches the graph once) (another way of thinking about this is "no two points can have the same value on the x axis)
