Answer:
Number of Fares to airport is 25 and number of fares from airport is 25.
Step-by-step explanation:
Given:
Total Number of fares =50
Let number of fares to airport be x.
Let number of fares from airport be y.
hence the equation can be framed as;
Also Given
Total Money Collected = $375
Cost to airport = $10
Cost from Airport = $5
Total Money Collect is equal to Cost to airport multiplied by number of Fares to airport plus Cost from airport multiplied by number of Fare from airport.
Dividing by 5 on both side we get;
Now Subtracting equation 1 from 2 we get;
Substituting the value of x in equation 1 we get;
Hence Number of Fares to airport is 25 and number of fares from airport is 25.
Answer
speed : metres per second (a)
perimeter : meters (b)
volume : cubic centimetres (d)
area : square metres (c)
Answer:
width = 3.5 m
length = 18 m
Step-by-step explanation:
area = length x width
x is the width then length = 2x + 11
x(2x + 11) = 63
2x^2 + 11x - 63 = 0
The formula to solve a quadratic equation of the form ax^2 + bx + c = 0 is equal to x = [-b +/-√(b^2 - 4ac)]/2a
with a = 2
b = 11
c = -63
substitute in the formula
x = [-11 +/- √(11^2 - 4(2)(-63))]2(2)
x = [-11 +/- √(121 + 504)]/4
x = [-11 +/- √625]/4
x = (-11 +/- 25)/4
x1 = (-11 + 25)/4 = 14/4 = 3.5
x2 = (-11 - 25)/4 = -36/4 = -9
since width can't be a negative number, x is 3.5
length = 2x + 11 = 2(3.5) + 11 = 18
Absolute value function domain is all real numbers
absolute value has vertex of(0,-3)
and it opens up
means that the lowest y value is -3
highest is infinity
domain=-inifnity to infinity
range=-3 to positive initnify
the answer is C for the domain and B for the range
