Answer: 9a-9b-6
7(3a−2b)+5b−3(4a+2)
Distribute:
7(3a−2b)+5b−3(4a+2)
=(7)(3a)+(7)(−2b)+5b+(−3)(4a)+(−3)(2)
=21a+−14b+5b+−12a+−6
Combine Like Terms:
=21a+−14b+5b+−12a+−6
=(21a+−12a)+(−14b+5b)+(−6)
=9a+−9b+−6
Obliviously check my work but if B is 42 then so is y. There are 360 degrees total so 360-2(42)= 276. Divide that by two and you get x=138
Answer: The axis of symmetry is x= -4
The domain is all real numbers
The function is negative over (“infinite sign”, -4)
Step-by-step explanation:
I’m not sure
Cross multiply
9x=36
(9)(4)=36
x=4
