Answer:
B. 5x−(−4x−6)=10
Step-by-step explanation:
The first equation gives an expression for y:
y = -4x -6
When that is used in the second equation, the result is ...
5x -y = 10
5x -(-4x -6) = 10 . . . . . . after substituting; matches B
Answer:
Assume:
(angle) RSB and angle (LSA) = D
and (line) ASR and (line) LSB is striaght then
(9x +27) + D = 180
(6x + 66) + D = 180
9x + D = 153
6x + D = 114
substitute
6x + D = 114
D = 114 - 6 x
9x + (114 - 6x) =153
3x = 39
x = 13
D = 114 - 6(13)
D=36
Step-by-step explanation:
The answer is A (3, 6)
plug it in: a of n(3) = (a of 2 which is 6)squared minus a of 2 which is 6.
you get: an(3)=36 minus 6 which equals 30
then plug it in for a of 4:
a of n(4) is 870=(a of 3 which is 30)squared minus a of three which is 30
so you get: 870=900 minus 30
that gives you the answer of 870=870 so answer #1 is correct
