8-4/5f=-14-2f
Multiply both sides by 5
40-4f=-70-10f
Move variable to left and change signs
-4f+10f=-70-40
Combine like terms
6x=-70-40
6f=-110
Divide both sides by 6
F=-55/3

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}

Which equation represents a circle with a center at (-3,5) and a radius of 6 units
Fittoniya [83]

Answer:

(x+3)^2 +(y-5)^2 = 36

Step-by-step explanation:

We can write the equation of a circle as

(x-h)^2 +(y-k)^2 = r^2  where (h,k) is the center and r is the radius

(x- -3)^2 +(y-5)^2 = 6^2  

(x+3)^2 +(y-5)^2 = 36
