Answer:
Division and multiplication are inverse operations. This means they "undo" each other. You can check your answer by multiplying the quotient by the divisor. You should get the dividend.
have a great day :)
We know that this ratio is directly because the two magnitudes go up.
In this case we will get the <u>proportionality constant</u> by dividing any term of the second magnitude by the first.
<h3>For example: </h3>
Now that we know that k = 3, we can know how much "<u>y</u>" will be if <em>x = 5</em>.
We just multiply:
<h3>Answer: <u>y = 15</u></h3>
Answer:
(-5,5) (-1,4)
Step-by-step explanation: Test each point either by graphing the system of inequalities or by substituting values to see which points satisfy both inequalities.
because it lies within the overlapping shaded region, (-5,5) is a solution.
Because it lies on a solid boundary of the overlapping region, (-1,4) is a solution.
Because they lie in the shaded region of only one inequality, not both, (0,5) and (0,-5) are not solutions.
Because it lies on a dashed boundary of the overlapping region, (-3,-3) is not a solution.
Lol, I did the tutorial.
