Scale Factor (K) = (new length/measure)/ (original length/measure)
for x-coordinate  = 8/2 = 4
for y-coordinate  = 16/4 = 4

K=4, expansion

K is the representation of "scale factor". Scale factor is the ratio of the lengths involved of the similar figures. It can be used to identify the kind of dilation, whether it is contraction or expansion. If the Scale Factor is greater than 1, then that means expansion and if it is less than 1, then it signifies contraction.

Equation 1 4y+1=x <br>equation 2 x=5y <br>solve the system of linear equations by substitution
Ymorist [56]
The first given equation is:
4y + 1 = x .......> equation I
The second given equation is:
2x = 5y .......> equation II

Substitute with equation I in equation II to get the value of y as follows:
2x = 5y
2(4y+1) = 5y
8y + 2 = 5y
8y - 5y = -2
3y = -2
y = -2/3

Substitute with the value of y in equation I to get the value of x as follows:
x = 4y + 1
x = 4(-2/3) + 1
x = -5/3

Based on the above calculations:
x = -5/3
y = -2/3

A block of ice melts 8oz every 5 minutes it began melting at 8:00am weighing 250 pounds at what specific time will it be complet
dimulka [17.4K]

Answer:

1:40 am the next day

Step-by-step explanation:

1 pound = 16 oz

The block of ice melts 1 pound or 16 oz in 10 minutes

10 x 250 = 2,500

It will take 2,500 minutes to melt completely.

2,500 divided by 60 = 41.66666 or 41 hours and 40 minutes              

60 minutes = 1 hour

1 day = 24 hours                    41.6666666 - 24 = 17.6666666

8 am + 17 hours and 40 minutes = 1:40 am the next day
