What adds to 1 and multiples to -90

Mathematics
1 answer:
wariber [46]3 years ago
6 0

Answer:

+10 and - 9

Step-by-step explanation:

If we consider the multiples of - 90

± 1, ± 2, ± 3, ± 5, ± 6, ± 9, ± 10, ± 15, ± 30, ± 90

The combination of multiples which multiply to - 90 and add to + 1 are

+ 10 and - 9

since 10 × - 9 = - 90 and 10 - 9 = 1

Which number line represents the solution set for the inequality 2x - 62 6(x - 2) + 8?
antoniya [11.8K]

Answer:

2x - 6 ≥ 6(x-2) + 8

2x - 6 ≥ 6x - 12 + 8

6x - 2x ≤ - 6 + 4

4x ≤ -2

4x/4 ≤ -2/4

x ≤ -1/2

Interval Notation: (- ∞, -1/2]

The line starts from -1/2 with the arrow going to the left (decreasing). The endpoint or value from where it started, which is -1/2, should be shaded.  The inequality symbol x ≤ -1/2 represents the values at most or maximum -1/2.
