Answer:
Step-by-step explanation:
We have been given that the variables y and x have a proportional relationship, therefore, we can represent the relationship between x and y as: , where k is proportionality constant.
Let us substitute x=3 and y=15 in above equation to find the value of k.
Now let us substitute k=5 and y=4 in our proportionality equation to find the corresponding value of x.
Therefore, the value of x will be 0.8, when y equals to 4.
Answer:
−(d+1)>3
Step 1: Simplify both sides of the inequality.
−d−1>3
Step 2: Add 1 to both sides.
−d−1+1>3+1
−d>4
Step 3: Divide both sides by -1.
