4 more than a number = x + 4
is more than = >
thirteen = 13
x + 4 > 13
Answer:
you estimate usally by the nearest 100. in this case its by 10 so your estimate answer is 30 because your final answer is 26. is the last number is greter than 5 you round up and lower than 5 you round down
Step-by-step explanation:
Answer:
b
Step-by-step explanation:
get y by itself in the second equation: y= 2x-3
substitute this into the y of the first equation:
2x+2x-3= 5
For this case we have the following variables:
t: time in seconds.
f (t): height as a function of time.
By the time Grace reaches the pool, the height is equal to zero.
We have the following table:
Time (t) (in seconds) Height f(t) (in meters)
1 25
2 20
3 15
4 0
We observe that the height is equal to zero after 4 seconds.
Equivalently:
Answer:
the following represents the x-intercept of f(t):
Grace reaches the swimming pool after 4 seconds
