What is the solution to the equation?12y + 6 = –18

A. y=-2
B. y=-1
C. y=1
D. y=2

Answers

Answer 1
Answer: You have to get Y alone on one side of the equals sign. Start by subtracting 6 from both sides (remember Inverse Operations?) Now you have 12y = -24 Now divide both sides by 12 and you get A. Y= -2!!!!! Hope this helps and, if you are able to do so, please mark Brainliest! Thanks!

Answer:

AB = 17.3 cm

Step-by-step explanation:

We require to find the measure of ∠A then use the cosine ratio to calculate AB

sum the parts of the ratio 3 + 2 = 5 parts, then

90° ÷ 5 = 18° ← value of 1 part of ratio

∠A = 2 × 18° = 36°, thus

cos36° = (adjacent)/(hypotenuse) = (14)/(AB)

Multiply both sides by AB

AB × cos36° = 14 ( divide both sides by cos36° )

AB = (14)/(cos36) ≈ 17.3 cm

How would you solve (4k+5)(k+1)=0?

Answers

(4k+5)(k+1)=0\iff4k+5=0\ or\ k+1=0\n\n4k=-5\ or\ k=-1\n\n\boxed{k=-(5)/(4)\ or\ k=-1}
(4k + 5) (k + 1) = 0

Before you rush off and start trying to do complicated things with that equation,
put your pencil down, fold your hands in your lap, and sit and look at it for a while.
Keep looking at it until a little voice yells out "Hey !  That's a true statement if
either (4k + 5) is zero  or  (k+1) is zero.  THEN go to work on it.

(4k + 5 = 0)
4k = -5
k = -5/4

(k + 1 = 0)
k = -1

And there are the two solutions to that equation.
