4x + 3x + 11 = 60
7x + 11 = 60 (Combine like terms)
7x = 49 (60-11)
x = 7 (49/7)
4x
4 (7)
28
Answer: RS = 28
Answer:
y = -3x-1 or 3x + y = -1
Step-by-step explanation:
6x + 3y - 11 = 0 can be written as y = -3x + (11/3)
In parallel lines the slope remains the same but the constant changes. To find the constant you place in the cordinates for x and y.
5 = -3(-2) + b
5 = 6 + b
5 - 6 = b
-1 = b
Now you replace (11/3) by the new b, -1
y = -3x - 1
Answer: 5. x=33, y= 33, z=114
Step-by-step explanation: the triangles and supplementary lines all add to 180, so find one of them, and use that one to find the others
Step-by-step explanation:
a1 = 27
r = -9/27 = -⅓
the formula :
an = a1. r^(n-1)
= 27. (-⅓)^(n-1)
= 3³(-3`¹)^(n-1)
= 3³(-3)^(1-n)
