Answer:

[tex]k(2) = 3[/tex]

[tex]t = 4[/tex]

Step-by-step explanation:

Given

[tex]k(t) = 2t - 1[/tex]

Solving (1): k(2)

Take t as 2 such that t = 2

This gives

[tex]k(2) = 2 * 2 - 1[/tex]

[tex]k(2) = 4 - 1[/tex]

[tex]k(2) = 3[/tex]

Solving (2): k(t) = 7

Substitute 7 for k(t)

[tex]7 = 2t - 1[/tex]

Add 1 to both sides

[tex]7 + 1 = 2t - 1 + 1[/tex]

[tex]2t = 8[/tex]

Divide both sides by 2

[tex]t = \frac{8}{2}[/tex]

[tex]t = 4[/tex]
