Answer:

a) B=950d

b) 23,750 lightbulbs

Step-by-step explanation:

a) You know that he makes 950 lightbulbs a day, therefore in "d" days, 950d lightbulbs will be produced.

b) Using the equation found in part A, find the number of lightbulbs for 25 days by plugging 25 in for the variable "d"

B=950d

B=950(25)

B=23,750 lightbulbs

If f(t) = 2t3 find each value.<br> f(4)<br> 3[f(t)]
quester [9]

The value of f(4) and 3[f(t)] if f(t) = 2t³ is 512 and 6t³ respectively.

<h3>What is polynomia?</h3>

To calculate the polynomial expression below, we use the technique below.

From the question,

Given:

  • f(t) = 2t³.............. Equation 1

To find f(4) we substitute 4 as the value of x in equation 1

  • f(4) = 2(4³)
  • f(4) = 512.

To find 3[f(t)] we multiply equation 1 by 3

  • 3[f(4)] = 3(2t³) = 6t³

Hence, the value of f(4) and 3[f(t)] if f(t) = 2t³ is 512 and 6t³ respectively.

<h2><em><u>PLEASE</u></em><em><u> </u></em><em><u>MARK ME</u></em><em><u> </u></em><em><u>BRAINLIEST IF</u></em><em><u> </u></em><em><u>MY ANSWER</u></em><em><u> </u></em><em><u>IS CORRECT</u></em><em><u> </u></em><em><u>PLEASE</u></em><em><u> </u></em></h2>

Step-by-step explanation:

The solution is given

|6x + 2|  - 6 > 8

|6x + 2|   > 8 + 6

|6x + 2|  > 14

Now wit will be swprated into two parts

First part

6x + 2  > 14

6x  >  14 - 2

x  > 12   \div  6

x > 8

The second part is

6x + 2  >   - 14

6x  > - 14 - 2

x >  - 16 \div 6
