Answer:
x = - 1
Step-by-step explanation:
(8x + 12) = 3 ( multiply both sides by 4 to clear the fraction )
3(8x + 12) = 12 ( divide both sides by 3 )
8x + 12 = 4 ( subtract 12 from both sides )
8x = - 8 ( divide both sides by 8 )
x = - 1
Answer:
a:

b:
-4+7
Step-by-step explanation:
here sorry it took so long
B) {x|x ∈ U and 2x is prime}
x is greater than 1.
the only even prime number is 2
2 times anything is even.
the minimum x value is 2. 2x is 4, therefore higher than the only even number
every value 2x will have a multiple of 2 so it will not be prime.
Answer:
240 degrees
Step-by-step explanation:
Looking at the graph we can see that the first peak is at -30 degrees and the second peak is at 210 degrees.
210 - (-30) = 210 + 30 = 240
