Answer:
The correct answer would be D. y+2=1/2(x+3)
Step-by-step explanation:
Point slope form can be written as y-y1=m(x-x1)
Since m is slope, we can see from the equation in slope intercept form that the slope is 1/2, so we can insert that into our equation. The rest is simply the process of inserting the values from the point on the graph into the equation.
Since y1=-2, we could put that as y--2 or y+2, since negatives cancel out.
Then we can replace x1 with -3, resulting in x--3 or x+3.
So our resulting equation is:
D.y+2=1/2(x+3)

Hello!
Explanation: This question's it's about the order of operations. It stands parenthesis, exponents, multiply, divide, add, and subtract. It can also go left too right.
First, you had to do is calculate parenthesis first.
Next, multiply from left too right.
Then you add left too right.
Final answer: →
Hope this helps!
Thank you!
Have a great day!

Reasoning solution:
40 oz of 10% glycol contains 40*0.1=4 oz of glycol, and 40-4=36 oz. of water.
To make a 25% glycol using 36 oz of water will make a total volume of 36*(4/3)=48 oz.
Volume of pure glycol to be added = 48-40=8 oz
Therefore 8 oz of pure glycol must be added to the mixture to make a 25% solution.
Algebraic solution:
Let x = volume of pure glycol required in oz.
then
0.10*40+1.00*x = 0.25*(40+x)
expand
4.0+x=10+0.25x
solve
(1-0.25x)=10-4=6
x=6/0.75=8 oz
Therefore 8 oz of pure glycol must be added to the mixture to make a 25% solution.
