Answer:
y=3
Step-by-step explanation:
Assuming this is an enlargement where EFGH is enlarged to ABCD then the former is the object and the latter is the image. If so then
scale factor(k) of the enlargement=image length/corresponding object length
k=3/2
Therefore, y=4.5/k
y=4.5/(3/2)
y=3
If we take the assumption another way and say ABCD is reduced to EFGH then the former is the object and the latter is the image.
In that case,
k=⅔
y=4.5×k
y=3
In either case y=3units
<span>So the question is what number do we have to multiply by 10 to get 7000. Lets turn that into an equation: the number we are looking for is x. x needs to be multiplied by 10 and we know that is equal to 7000. So: 10*x=7000. When we divide both sides of the equation by 10 we get: x=7000/10 and that is x=700. So the number we are looking for is 700.</span>
Line passes though points (-1 , 0) and (0 , -1).
Equation of line in two point form :
14 200 × 1,57 = 22 294
22 294 - 14 200 = 8 094
The increased +8 094 sales
