Answer:
A'(5,3)
Step-by-step explanation:
First, you must understand that A(5,3) is the pre-image and that A' is what we are looking for which is the image.
With that in mind, you translate the preimage by adding or subtracting from the x and y values.
(x+4, y-3)
To find the x value of the pre-image, you will add 4 to the preimages' x value
Pre-image: A(1,6)
To find the y value, you subtract the preimages' y value by 3.
Hope this helps!
Answer:
21 weeks
Step-by-step explanation:
In this question, we are to use proportionality to find the solution to the question.
We were made to know that the time taken to build the highway is varied directly with the length and inversely with the number of workers.
Let us make a mathematical representation for this.
Let the time be t, number of workers be w and length be l
t is directly proportional to l and inversely proportional to w
Mathematically;
t = kl/w
Where k is the constant of proportionality.
Let’s find the value of k
150 workers built 12 miles of highway in 14 weeks ; plug these in the equation to get k
14 = k * 12/150
k = 150 * 14/12 = 175
Now we want to get t given w and l
from ;
t = kl/w
We can get t; where l = 15 and w = 125
t = 175 * 15/125
t = 21 weeks
