Step-by-step explanation:






Answer:
35 degrees
Step-by-step explanation:
The angle is given to be a right angle by the red square. The right angle is intercepted by a line. One side of the whole 90 degree angle is said to be 55 degrees. Both sides should equal 90 degrees if added.
This means that to find the missing angle, you would subtract 55 degrees from 90 degrees to get 25 degrees.
As x and y vary directly then <span>x∝y</span> i.e. <span>x=ky</span>, where k is a constant.
When <span>x=24</span>, <span>y=8</span> i.e. <span>24=k×8</span> and therefore
<span>k=<span>248</span>=3</span>
and relation between x and y is hence <span>x=3y</span>
and when <span>y=9</span>, <span>x=3×9=27</span>.
I hope this is what you're looking for.
Answer:
y = - 10x
Step-by-step explanation:
The equation representing a proportional relationship is
y = kx ← k is the constant of proportionality
y = - 10x ← is the only equation in this form
Thus the equation is y = - 10x with k = - 10
