The greater density to measure by having a mass of 2cm or 3cm
Answer:
an = -6n + 5.
Step-by-step explanation:
This is an arithmetic sequence with first term a1 = -1 and common difference d = -6
an = a1 + d(n-1)
an = -1 + -6(n - 1)
an = -1 -6n + 6
an = -6n + 5.
In standard form the two equations are
7x +y = 5
7x +y = -5
The equations describe lines that are parallel.
Sense the two triangles are congruent you would use CPCTC.
8 or 8 1/2 because you won't finish the ride due to 28 + 3 1/2 being odd
