None of the triangles listed has two equal base angles or two equal side lengths, therefore: D. No triangle is isosceles.
<h3>Properties of an Isosceles Triangle</h3>
- An isosceles triangle has two base angles having equal angle measure.
- The side lengths that are opposite each of the equal base angles are also congruent to each other.
Thus, none of the triangles listed has two equal base angles or two equal side lengths, therefore: D. No triangle is isosceles.

The required equation is: 
Option C is correct.
Step-by-step explanation:
The proportional relationship can be found using the equation: 
where x and y are the points and k is the constant of proportionality.
We need to find k.
From the graph given, we can locate points x and y:
x=5, y= 35 then k would be:
x=10, y=70 then k would be:
For each values of x and y, the constant of proportionality k is 7
So, the required equation is:
Option C is correct.

Answer:
M = 1.5
Step-by-step explanation:
First, apply the distributive property to the problem. For this, you will multiply 4 x m, then 4 x 3.
Now, your problem looks like
4m + 12 = 18
Next, you need to get the variable isolated. For this, you need to subtract 12 from both sides.
Now, your problem looks like
4m = 6
Next, you can divide both sides by the non-constant term, which is 4m, so divide by 4.
Now, your problem looks like
M = 1.5

2, since 2x 1/3 is 2/3, which is less than 3/4.
Answer: Let us assume that the number of months after which
the gym memberships will cost the same = x
Then
15 + 10x = 40 + 4x
10x - 4x = 40 - 15
6x = 25
x = 25/6
= 4 1/6
So the membership fee of both the gyms will become same after 4 1/6 months. You can also consider that as after 5 months the membership fees of both the gyms will become same. I hope the procedure is not very complicated for you to understand.
Step-by-step explanation: Hope this helps!!
