How many solutions does the system have? y = -7x + 8 y = -7x - 8 Choose 1 answer:

Mathematics
1 answer:
Verdich [7]3 years ago
7 0

Answer:

No solutions

Step-by-step explanation:

If we try to solve this system for y at x = 1, we get an impossible situation:

y=-7(1)+8=-7+8=1\\y=-7(1)-8=-7-8=-15\\1=-15

Clearly, 1 ≠ -15, and we'll see that any value of x that we pick gives us two contradictory values for y, so this system has no solutions.

A piece of wood is divided into two pieces in the ratio of 2:5. One piece is 10 cm long so how long is the other piece?
klio [65]

Answer:

The length of the pother piece of the wood is 25 cm.

Step-by-step explanation:

Let the length of a piece of wood is x such that the ratio of two pieces is 2:5. Two pieces are 2x and 5 x

Length of the first piece is 10 cm. It means, 2x = 10 i.e. x = 5

We have considered that the length of other piece is 5x. It means 5×5 = 25 cm.

Hence, the length of the pother piece of the wood is 25 cm
