Mathematics
1 answer:
tester [92]3 years ago
6 0

Regroup terms

b/8 - 17 = 13

Add 17 to both sides

b/8 = 13 + 17

Simplify 13 + 17 to 30

b/8 = 30

Multiply both sides by 8

b = 30 × 8

Simplify 30 × 8 to 240

<u>b = 240</u>

For the function f(x) = |2x-7| - 3 find f(2)
olasank [31]
Evaluate abs(2 x - 7) - 3 where x = 2:abs(2 x - 7) - 3 = abs(2 2 - 7) - 3
2×2 = 4:abs(4 - 7) - 3
4 - 7 = -3:abs(-3) - 3
Since -3<=0, then abs(-3) = 3:3 - 3
3 - 3 = 0:Answer: 0
