If they are similar they are by a ration of 1:2 but you dont know all the angles or all the sides.
Answer:
Amount left = Rs 45
Step-by-step explanation:
Let the initial amount be x.
Translating the word problem into an algebraic expression, we have;
Cross-multiplying, we have;
Rearranging the equation (collecting like terms), we have;
x = Rs 60
Next, we find the amount left;
Amount left = 60 - 15
Amount left = Rs 45
Answer:
a proportional relationship exists if the ratio of values is a constant
Step-by-step explanation:
The equation describing a proportional relationship is ...
y = kx
If you are given a table of values of x and y, they will be proportional if ...
y/x = k
for all (x, y) pairs.
Answer:
its the last one
Step-by-step explanation:
parallel lines have negative reciprocal slopes
so 1/2 becomes -2
point slope form
y-y1 =m(x-x1)
y-0 = -2(x--4)
y =-2(x+4)
y=-2x-8
