Which of the following is(are) the solution(s) to | 3x + 10 | = 10

The possible solutions to the function are x = 0 and x = -20/3

Step-by-step explanation:

Given the equation | 3x + 10 | = 10, the solution to the equation will be two values due to the modulus sign.

Note that any value in a modulus sign can either be positive or negative.

For the positive value of | 3x + 10 | = 10:

3x+10 = 10

3x = 10-10

3x = 0

x = 0

For the negative value of | 3x + 10 | = 10:

-(3x+10) = 10

-3x-10 = 10

-3x = 10+10

-3x = 20

x = -20/3

The possible solutions to the function are x = 0 and x = -20/3

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
