Evaluate t(1),t(2),t(3),t(4)

t(1)=4.5(1)-8=4.5-8=-3.6
t(2)=4.5(2)-8=9-8=1
t(3)=4.5(3)-8=13.5-8=5.5
t(4)=4.5(4)-8=18-8=10

the first 4 terms are
-3.6,1,5.5, 10

Simplifying t(n) = 4.5n + -8 Multiply t * n nt = 4.5n + -8 Reorder the terms: nt = -8 + 4.5n Solving nt = -8 + 4.5n Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-4.5n' to each side of the equation. -4.5n + nt = -8 + 4.5n + -4.5n Combine like terms: 4.5n + -4.5n = 0.0 -4.5n + nt = -8 + 0.0 -4.5n + nt = -8 <span>Reorder the terms: 8 + -4.5n + nt = -8 + 8 Combine like terms: -8 + 8 = 0 8 + -4.5n + nt = 0 The solution to this equation could not be determined.</span>

Vladimir79 [104]

#3

2 and three are supplementary angles .

#4.

The answer is opposite angles .

  • Hence there is no option

#5

Bisected angles are equal

\\ \sf\longmapsto 5x=3x+10

\\ \sf\longmapsto 5x-3x=10

\\ \sf\longmapsto 2x=10

\\ \sf\longmapsto x=\dfrac{10}{2}

\\ \sf\longmapsto x=5

Now

m<ABC

\\ \sf\longmapsto 5x+3x+10

\\ \sf\longmapsto 8x+10

\\ \sf\longmapsto 8(5)+10

\\ \sf\longmapsto 40+10

\\ \sf\longmapsto 50
