Answer:

y+4=-2/3 (x+1)

Step-by-step explanation:

-1 = x1

-4 = y1

m = -2/3

slope - intercept form = y - y1 = m(x - x1)

y-(-4) = -2/3(x - (-1))

y + 4 = -2/3(x +1)

Korvikt [17]

We are given : Giannina's painting sold for over $300.

Let the price of Geannina's painting in dollars = P.

<em>Note: We are given a word " over " in above statement.</em>

Over word represents more than. So, we need to use more than inequality symbol to write an inequality for the given statement.

Let us rephrase the given statement.

" Price P is greater than $300".

Now, we can write an inequality :

P> 300.

<h3>Therefore, the required inequality for given statement is P > 300.</h3>

y= mx+b

(16, -7) = (x,y)

2(16) - 3y = 12

32 - 3y = 12

32 - 12 = 3y

20/3 = y

6.6 = y

2x-3(-7) = 12

2x+21 = 12

2x = 12 - 21

x = -9/2

Insert the values into y = mx + b

solve for m and then solve for b

Whatis the value of y?​
Romashka [77]
Answer is A, y = 65

The top angle is 50 because 180 - 130 = 50
Since the top angle is 50, the two bottom angles have to add up to 130. Since the bottom angles are the same, you can do 130 / 2 to find the angles which equals 65.
