7y - 9 = 2(y - 4) + 1​

Mathematics
1 answer:
MatroZZZ [7]3 years ago
6 0

Answer:

Step-by-step explanation:

Distribution comes first, so:

7y-9 = 2y-8+1

Then you simplify:

7y-9 = 2y-7

Then you subtract or add the lowest number with a letter:

5y-9 = -7

Now you get 5y alone, so we add the 9:

5y = 2

Then you divide 5y = 2 by 5

y = 2/5 or .4

Given the coordinates of the triangle expressed as:

A(1. 5), B(2, 3), and C(5, 4)

When these coordinates are reflected over the y-axis, the results will be:

A'(-1, 5), B'(-2, 3), and C'(-5, 4)

<em>Note that the x coordinates were negated while the y-coordinates remains unchanged</em>
