Which graph shows the solution to the equation below?<br> log3(x+2) = 1
sdas [7]

Refer the attached figure of the graph (Option A) that shows the solution to the given equation

<u>Step-by-step explanation:</u>

The given logarithmic equation is

         \log _{3}(x+2)=1

The solution to this logarithmic equation is where the graph of

         y=\log _{3}(x+2)

When comparing above with the given equation, we find that y = 1.

Now, find the 'x' value by using this. So, applying log base 3 rule on right side, we get as below,

    x+2=3^{1}

   x = 3 - 2 = 1

Plot the asymptote and the point (1 , 1). Sketch the log curve using those two reference facts.  Hence, concluded the graph in option A as solution to the given equation.

There is a line that includes the point ( 18,-19) and has a slope of 0 what is its equation in slope-intercept form
wolverine [178]
The equation is y = mx + b

(18, -19)

substitute these numbers in the equation

-19 = 0(18) + b

-19 is y because it is the y slot in the cordinate and I put 0 for m because m is the slope and x is  18

-19 = 0 + b

b= -19

the equation is 

y = 0(x) - 19

y = -19

Answer:

<h2>Bibi ate 6.3 pounds of food, approximately.</h2><h2>Rexy ate 5.7 pounds of food, approximately.</h2>

Step-by-step explanation:

1. What is this situation about?

The situation described is about the amount of food those dogs eat, and its relation with their weights.

2. What are the quantities in this situation?

The quantities are aboth the weight of each dog, and the number of pounds of dog food.

3. What mathematical questions could we ask?

We could ask the pounds of food each dog eats, in proportion with their weights.

4. Answer the question.

To answer that question, we just need to form a proportion.

\frac{8}{10.5}=\frac{12-x}{x}

Where 12-x is the total pounts Rexy ate, and x is the total pounts Bibi ate.

8x=126-10.5x\\8x+10.5x=116\\18.5x=116\\x=\frac{116}{18.5} \approx 6.3

Therefore, Bibi ate 6.3 pounds of food, approximately.

Then, 12-x = 12-6.3 = 5.7

Which means, Rexy ate 5.7 pounds of food, approximately.
