Answer:

59

Step-by-step explanation:

<em>You can just replace y with its value which is 5. </em>

4y² - 7y - 6 = 4(5²) - 7(5) - 6

                  = 4 × 25 - 35 - 6

                  = 100 - 35 - 6

                  = 59

Answer and Step-by-step explanation:

Let's plug 5 in for y.

4(5)^{2}  - 7(5) - 6\\\\\\\\4(25) - 35 - 6\\\\\\100 - 35 - 6 = 59\\\\\\

<u>The value of </u>4y^{2}  - 7y - 6<u> when </u>y is equal to 5<u> is 59.</u>
