Answer:

8x = 32

x = 4

y = 6

Step-by-step explanation:

2.5y + 3x = 27

5x – 2.5y = 5

_____________

8x = 32 (equation obtained after adding the two equations)

x = 32/8

x = 4

Plug x = 4 in 2.5y + 3x = 27

2.5y + 3*4 = 27

2.5y + 12 = 27

2.5y = 27 - 12

2.y5= 15

y = 15/2.5

y = 6

If the point (3,5) is on f(x) find the corresponding point on the graph of y=(x+2)+1
ad-work [718]

The corresponding point to the point given (3,5) which is on the graph of f(x) as described in the task content is; (3,6).

<h3>What is the corresponding point to the given point (3,5) as given in the task?</h3>

It follows from the task content that the point given originally is; (3,5).

However, it is required that the point which is equivalent to the given point on the graph of y=(x+2)+1 be identified.

It therefore follows that the point required as in discuss is;

y = (3+2) +1

y = 6.

Hence, the corresponding point is; (3,6).
