Cx/a+f=b solve for x

Mathematics

(cx/a) + f = b

isolate the x. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract f from both sides

(xc/a) + f (-f) = b (-f)

xc/a = b - f

Next, multiply a to both sides

(xc/a)a = (b-f)a

Distribute a to all terms within the parenthesis

xc = ab - a(f)

Finally, to isolate the x, divide c to both sides

(xc)/c = (ab - a(f))/c

x = (ab - a(f))/c

x = (ab - a(f))/c is your answer

hope this helps

Which is f(5) for the function -2x2 + 2x - 3?

Schach [20]

The value of f(5) is -37

Solution:

Given function is:

$f(x) = -2x^2+2x+3$

We have to find the value of f(5)

To find the value of f(5), we have to substitute x is equal to 5 in given function

Plug in x = 5 in f(x)

$f(x) = -2x^2+2x+3\\\\f(5) = -2(5)^2+2(5) + 3\\\\\text{Simplify the above expression }\\\\f(5) = -2(25) + 10 + 3\\\\\text{Solve the above expression }\\\\f(5) = -50 + 10 + 3\\\\f(5) = -40 + 3 = -37$

Thus value of f(5) is -37

I NEED HELP WITH THIS Q1

levacccp [35]

Answer:

$\frac{1}{4} (x-5)=13$

Step-by-step explanation:

So when we multiply this is what we get:

$\frac{x-5}{4}=13$

then we multiply the 4 by 13:

$x-5=52$

then after that we add 52+5 and we get:

$x=57\\$
