Answer:
Step-by-step explanation:
80,120,160.....
This is an arithmetic sequence
common difference (d) = 2nd term - 1st term
= 120 - 80 = 40
first term (a) = 80
nth term = a + (n-1)d
= 80 + (n-1)*40
= 80 + 40n -40
= 40 + 40n
(x-4)(x+9) because X to the power of 2 +9x+(-4x)-36 =(x-4)(x+9)
2. 4(0) - 20(0) < 6
(5/2 (0)) >/= 5(0) - 10 ; it is a solution
3. 2.5 + 5(-1.5) > -10
2.5 - (-1.5) </= 4 ; it is also a solution
x y
( 0 , 0 )
(2.5, -1.5)
Plug it in, plug it in
Answer:
x = 48
Step-by-step explanation:
We now that supplementary angles (as is the case for a straight line) add up to 180 degrees.
3x - 12 + x = 180
4x = 192
x = 48
