Answer:
-5
Step-by-step explanation:
Let x be the number.
4*(x-3)=3+4x+3x
4x-12=3+4x+3x
-12-3=3x
-15=3x
x=-5
Given:
There exist a proportional relationship between x and y.
To find:
The equation which represents a proportional relationship between x and y.
Solution:
If there exist a proportional relationship between x and y, then
where, k is constant of proportionality.
We know that, proportional relationship passes through the origin because (0,0) satisfy .
For x=0, check which equation has y=0.
In option A, .
In option B, .
In option C, .
In option D,
Only in option C, we have a equation of the form with 4 as constant of proportionality and it passes through (0,0).
<h2><u>Therefore, the correct option is C.</u></h2>
Answer:
307 meters tall
Step-by-step explanation:
190.5 / 62 = x / 100
19050 / 62 = 307
If it is rounded up.
It would be all real numbers
3a^2 + 9
= 3a^2 + 3^2
= 3(a^2 + 3)
