Vertical angles are always Congruent.
Answer:
(3x-2)(4x-1)
Step-by-step explanation:
1. take the a and the c value and multiply them together to isolate x^2. it should be x^2 -11 +24.
2. find what multiplies to 24 and adds up to -11. its -8 and -3.
3. factor like normal and get (x-8) (x-3)
4. divide the -8 and -3 in the factors by 12 (the original a value)
-8/12 = -2/3 and -3/12 = -1/4.
5. the denominator gets moved to the x value to get (3x-2)(4x-1)
Step-by-step explanation:
a.) All real numbers x greater than 2
===> X > 2
b.) 6 more than a number k is less than or equal to 12
===> 6+k =< 12
Answer:
4 months and 7 months
Step-by-step explanation:
C = 30x + 50
C is cost so when we spend $170 we can solve for x.
$170 = 30x + 50
170 - 50 = 30x + 50 - 50
170 - 50 = 30x
120 = 30x
120/30 = 30x/30
120/30 = x
4 = x
So he has played 4 months when he spends $170
C is cost so when we spend $260 we can solve for x.
$260 = 30x + 50
260 - 50 = 30x + 50 - 50
260 - 50 = 30x
210 = 30x
210/30 = 30x/30
210/30 = x
7 = x
So he has played 7 months when he spends $260
