math
Answer:
50 and 60 mph respectively
Step-by-step explanation:
Step one:
given data
total distance= 450 miles
time take= 9 hours
Required
Tom and Tammy's average speed
Step two:
Tom's average speed= 450/9
= 50 miles per hours
Tammy's average speed= 450/7.5
= 60 miles per hours
Answer:
global warming
Step-by-step explanation:
icebergs are melting which in the future can cause floods and also the warmer earth gets then the crops 2ouldnt grow
Answer:
Vertical angles = 81 degrees
Angle (4y-1) = 99 degrees
Linear pair = 81 + 99 = 180 degrees
Step-by-step explanation:
2x + 5 = 3x - 33 (vertical angles)
33+5 = 3x - 2x
38 = x
3(38) - 33 = 81 degrees
4y - 1 + 81 = 180 (linear pair angles)
4y = 180 - 80
y = 100/4
y = 25
4(25) -1 = 99 degrees
For this case we have a function of the form 
. Where:
By definition, the domain of a function is represented by the set of values of the independent variable, x, for which the value of the variable y can be calculated.
For its part, the range is represented by the values of "and".
So:
Thus, the range is {-3,1,2}
Answer:
{-3,1,2}
