Answer:
2y = x, which is a proportional relationship.
Step-by-step explanation:
See the table attached.
The table gives the ordered pair represents a proportional relationship.
Take at least two pairs of the value of x and y.
Let they are (6,3) and (10,5).
Now, the equation for the straight line passing through the two points is given by
⇒ 2(y - 5) = x - 10
⇒ 2y - 10 = x - 10
⇒ 2y = x
Hence, we can write x ∝ y and the constant of proportionality is 2. (Answer)
Answer:
The base is 4cm and the height is 5cm.
Step-by-step explanation:
This is a solve the system question. Call H the height of the triangle and B the base. The question tells us:
and
Sub the first equation into the second (as H is already isolated). You will end up with a quadratic equation - solve that any way you wish (e.g. quadratic formula). I've provided the factored form below which shows you the roots:
In this question, we take B=4. You can't have a negative side length so the other answer is eliminated. Now sub the value for B into either of the original equations. I'll use the first, again because H is already isolated:
