Question

Solve the inequality 5u≤8u−21 and write the solution in interval notation

Answer 1

Answer:

Step-by-step explanation:

$5u\leq 8u-21$

Subtract 8u from both sides

$-3u\leq -21$

Divide by -3 on both sides

$u\geq 7$

Interval notation: [greater/less than or equal to], (greater or equal to)

[7,∞)
