Answer:
Yes by AAA
Step-by-step explanation:
Angle A is the same for both triangles. Angle D is congruent to Angle A since BC and DE are parallel lines and same with angle E. So by AAA the triangles are similar
Answer:
10
Step-by-step explanation:
(3x+1)=3*3+1=9+1=10
Answer:
1. -3 = -8, 0 = 1, 2 = 7
Step-by-step explanation:
1. Plug in the x values for x in the equation and graph the coordinates (examples; (-3, -8))
2. do the same thing as #1
example; y = -(-3) - 2
3. Plug in 2 into the equation, giving you your y value, and plug the coordinates in
4. you can make up the x coordinates, I would do -1, 0, 1, and 2. and just plug those in for the x in the equation and graph.
5. Follow the same steps as the last problems but just connect the points
6. Same steps as the other problems, just pick some points and plug them into the equation.
I hope this helps
Answer:
a(n) = -81(-4/3)^(n - 1)
Step-by-step explanation:
The first term is -81. From -81 we obtain the next term, 108, by multiplying -81 by -4/3. Note how (-4/3)(108) = -144 as anticipated.
Thus, the common ratio is -4/3.
The explicit function for this geometric series is
a(n) = -81(-4/3)^(n - 1)
Included a pic of the solution and work.
