First step: you have to plug in 6y+3 into the equation and solve
Example: 6y+3+2y = 5
Yes it is because ( hey i actually dont know the answer) the calculation of calcullas
Answer:
See below
Step-by-step explanation:
First off, the missing side is c=√(17²-8²)=15
sinø=opposite/hypotenuse=15/17
cosø=adjacent/hypotenuse=8/17
tanø=opposite/adjacent=15/8
cscø=hypotenuse/opposite=1/sinø=1/(15/17)=17/15
secø=hypotenuse/adjacent=1/cosø=1/(8/17)=17/8
cotø=adjacent/opposite=1/tanø=1/tanø=1/(15/8)=8/15
Answer:
b=-19
Step-by-step explanation:
We know that one of the solutions is x=-4/5
That is a solution to x. So if we plug in (-4/5) into the x in the equation, then it should equal 0.
5(-4/5)^2+b(4/5)+12=0
Now, just solve for b.
5(16/25)+b(4/5)+12=0
(16/5)+(4/5)b+12=0
(76/5)+(4/5)b=0
(4/5)b=-(76/5)
b=-19
