What is the solution to y + 7 = -9 A. y = -16 B. y = -2 C. y = 2 D. y = 16

Helen [10]

Answer:

A. y = -16

Step-by-step explanation:

Hello!

What we do to one side of the equation we have to do to the other.

y + 7 = -9

We have to get y by itself so we have to get rid of the seven by doing the opposite of what it says

The opposite of addition is subtraction so we subtract 7 from both sides

y + 7 - 7 = -9 - 7

Solve

y + 0 = -16

Simplify

y = -16

The answer is A. y = -16

Hope this helps!

(m+2)(m+3)=(m+2)(m-2)

Anastaziya [24]

(m+2)(m+3)= (m+2)(m-2)
⇒ m^2+ 3m+ 2m+ 6= m^2 -4
⇒ 5m+ 6= -4 (m^2 on both sides cancels out)
⇒ 5m= -4-6
⇒ 5m= -10
⇒ m= -10/5
⇒ m= -2

The final answer is m=-2~

Marco created a table to help him represent the sample space of spinning a spinner and flipping a coin. Result of spin Result of

Svetradugi [14.3K]

The probability that the result is green - tail is 1/6.

Spinner has three colors that are red, green and yellow and coin has two sides that are head or tail.

<h3>What is the formula for probability?</h3>

Divide the number of events by the number of possible outcomes

The sample space is, ${(red - head; red - tail; green - head; green - tail; yellow - head; yellow - tail)}$ In total there are 6 ways to combine different colors with coin sides.

Therefore ,the probability that the result is green - tail is 1/6.
