Answer:
CBD = 63 degrees
Step-by-step explanation:
To find CBD, we must first find the value of x. To do so, we use this equation since CBD and ABC equal 96 degrees:
(6x+27) + (7x-9) = 96
13x+18 = 96
13x+18-18 = 96-18
13x = 78
13x/13 = 78/13
x = 6
Now that we know the value of x, we factor it in to CBD to find its true value:
6x+27
6(6)+27
36+27
= 63 degrees
To check if this answer is correct, we can also find the value of ABC and see if the two values equal 96:
7x-9
7(6)-9
42-9
= 33 degrees
63 + 33 = 96
The answer is correct. CBD = 63 degrees and ABC = 33 degrees.
Y=-3x-5 would be the slope
Answer:
20
Step-by-step explanation:
To get to -10 from 5 you have to subtract 15
to get to 20 from -10 you have to add 30
Repeat that process until you get to the 6th term.
5 (1st term)
5 - 15 = -10 (2nd term)
-10 + 30 = 20 (3rd term)
20 - 15 = 5 (4th term)
5 + 30 = 35 (5th term)
35 - 15 = 20 (6th term)
Answer:
18x + 91
Step-by-step explanation:
A18
18 is the exponent, am not sure because I see this topic a really long time ago, but I think that you multiply the exponent because the sign is multiplication
