the function f is defined by f(x)=150/x-z where z is a constant. find z if the value of f at x=1/5 is equal to 250
malfutka [58]

Answer:

x = -1 \frac{1}{20}

Step-by-step explanation:

f(\frac{1}{5}) = 120, therefore we can create this equation:

120 = 150 ÷ (\frac{1}{5} - z)

cross-multiply to get: 24 - 120z = 150

-120z = 126

z = -1 \frac{3}{60}

exis [7]

Answer:

Step-by-step explanation:

cartesian plane :

quadrant 1 : both x and y are positive

quadrant 2 : x is negative, y is positive

quadrant 3 : both x and y are negative

quadrant 4 : x is positive and y is negative

(-2,4)......we have x is negative and y is positive...so we are in quadrant 2

(3,-1)....we have x is positive and y is negative...in quadrant 4

(-1,0) ...if u have a 0 in ur points, they do not lie in any quadrant because they are located on an axis....this is located on axis x

(1,2)....both are positive....located in quadrant 1

(-3,-5)...both are negative.....quadrant 3
