we have
we know that
If the point is an equation solution, it must satisfy the equation.
<u>case a</u>) 
Substitute the values of x and y in the equation
-------> the point is not solution of the equation
<u>case b</u>) 
Substitute the values of x and y in the equation
-------> the point is solution of the equation
<u>case c</u>) 
Substitute the values of x and y in the equation
-------> the point is not solution of the equation
<u>case d</u>) 
Substitute the values of x and y in the equation
-------> the point is not solution of the equation
therefore
<u>the answer is</u>
The point is solution of the equation
4(0.6)-(-3.8)=
2.4+3.8=6.2
Hope this helps
The answer is 44 which is rounded to the nearest percent
Answer:
She must swim 10 feet before she reaches the surface; from <em>level -10</em> to<em> level 0 (Equation: </em>
)
Step-by-step explanation:
Based on the information provided, you can assume that the surface of the lake is at <em>level 0.</em>
You know that the swimmer dives 10 feet below the surface; this is the <em>level -10 .</em>
This means that she must swim 10 feet from the <em>level -10</em> to the level 0 in order to reach the surface of the lake.
Therefore, to find how far she must swim before she reaches the surface, it is necessary to add<em> levels -10 </em>and <em>+10</em> to get the<em> level 0.</em> This can be represented with the following equation:
24 feet, 40 feet, and 56 feet this is because using the ratio given 3:5:7
you can multiply
3x8=24
5x8=40
7x8=56
This shows that it follows the ratio lastly you need to make sure the numbers add up to 120
24+40+56=120
So A is your answer can I be marked brainiest please
