Answer:
Directly proportional relationships always pass through the origin (0,0). There are other linear relationships that do not pass through the origin.
Answer:
3
Step-by-step explanation:

If
is 3, then



Both
and
equal 3. So, the value of
must be 3 for the function to have the same coordinate for
and
.
<h3>The equation is:</h3><h3>

</h3><h3>The number is 3 or 4</h3><h3><em><u>Solution:</u></em></h3>
Given that,
7 added to the square of a number is equal to 7 times the number, minus 5
Let "x" be the unknown number
From given,
7 added to square of x = 7 times the x minus, 5

Solve the above equation

Split the middle term

We have two solutions
x - 3 = 0
x = 3
And
x - 4 = 0
x = 4
Thus number is 3 or 4
