Answer:

x = 3

Step-by-step explanation:

5(2 - x) = 7x - 26

Distribute;

10 - 5x = 7x - 26

Add 5x to both sides;

10 = 12x - 26

Add 26 to both sides;

36 = 12x

Divide both sides by 12;

x = 3

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

Please explain how to find the answer for this

FromTheMoon [43]

$P(A \textrm{ and } B) = P(A) P(B|A)$

$P(A \textrm{ and } B) = \dfrac{3}{10} \cdot \dfrac{2}{5} = \dfrac{3}{25}$

Second to last choice.
