Which of the following is(are) the solution(s) to |5x+2|=8 ?

slega [8]

Answer:

x = 6/5 or x = -2

Step-by-step explanation:

We need to solve:

|5x+2|=8

We know that |u|=a the u = a and u = -a

Now solving:

|5x+2|=8

5x +2 = 8 or 5x +2 = -8

5x = 8-2 or 5x = -8-2

5x = 6 or 5x = -10

x = 6/5 or x = -10/5

x = 6/5 or x = -2

So, x = 6/5 or x = -2

What is the product of (2p+7)(3p+4p-3)

Alex

Answer:

The answer is C=6p3 + 29p2 + 22p – 21

Step-by-step explanation:

To calculate the product, we need to multiply each member of each multiplier:

(2p + 7)(3p2 + 4p – 3) = 2p · 3p² + 2p · 4p + 2p · -3 + 7 ·3p² + 7 · 4p + 7 · -3

= 6p³ + 8p² - 6p + 21p² + 28p - 21

= 6p³ + 8p² + 21p² + 28p - 6p -21

= 6p³ + 29p² + 22p - 21

Therefore, the product of (2p + 7)(3p2 + 4p – 3) is 6p³ + 29p² + 22p -21

Evaluate the function. f(x) = 3x² – x Find f(10)

kirill [66]

Answer:

Step-by-step explanation:

<u>Function Evaluation</u>

Given a function f(x) as an explicit expression, finding f(x=a) implies substituting the value of x by a in every instance it occurs.

We are given the function:

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

It's required to find f(10). We replace the x for 10:

$f(10)=3*10^2-10$

Operating:

$f(10)=3*100-10$

$f(10)=300-10$

$f(10)=290$

Thus, f(10)=290
