Answer:
A function is a relation in which each possible input value leads to exactly one output value.The input values make up the domain, and the output values make up the range.
Step-by-step explanation:
Answer:
The measure of angle N is 32°.
Step-by-step explanation:
Since all the angles of a triangle add up to 180, set all 3 angle measures to 180.
90 + 58 + m∠N = 180
Combine like terms
148 + m∠N = 180
Subtract 148 from both sides.
m∠N = 32
Answer:
y= 1/3x+2
Step-by-step explanation:
m= slope
y-intercept= b
For the answer to the question above, to solve the average increase between hours 2 and 4, first let as solve the the number of student in each hour
x = 2f(x) = 4x -1f(2) = 4(2) - 1f(2) = 7
x = 3f(x) = 4x -1f(3) = 4(3) - 1f(3) = 11
x = 4f(x) = 4x -1f(4) = 4(4) - 1f(4) = 15
increase in hours 2 to 4increase per hour = 15 - 7 / 4 - 2increase per hour = 4 students per hour
You can substitute 20 + d for c in the first equation which gives you
20+ d = 100 - d then solve
2d = 80
d= 40
then put the value for d back into one of the original equations
c= 20 + d
c = 20 + (40)
c = 60
