Answer:
x=8 and y=53
Step-by-step explanation:
Given function:
Find x:
- the two equation, the x and are breaked apart..
- so find a number that they can both equal to together and has the same y.
- multiply by 8..
·
- combine the terms for x and 13
- since x is 8 then if we add 8 with 45 it should be 53...
y is:
Therefore, x=8 and y=53..

Answer:
y=x-2
Step-by-step explanation:
to get -2 to -4 you would have to add -2
if we follow the pattern of subtracting 2 then you would see that -2 is b sense we are subtracting.
The m value doesn't have to change so we would leave the x how it is
The goal for this question is to find the pattern the numbers share though out the table.
To solve this problem, let us first assign some
variables. Let us say that:
x = pigs
y = chickens
z = ducks
From the problem statement, we can formulate the
following equations:
1. y + z = 30 --->
only chicken and ducks have feathers
2. 4 x + 2 y + 2 z = 120 --->
pig has 4 feet, while chicken and duck has 2 each
3. 2 x + 2 y + 2 z = 90 --->
each animal has 2 eyes only
Rewriting equation 1 in terms of y:
y = 30 – z
Plugging this in equation 2:
4 x + 2 (30 – z) + 2 z = 120
4 x + 60 – 2z + 2z = 120
4 x = 120 – 60
4 x = 60
x = 15
From the given choices, only one choice has 15 pigs. Therefore
the answers are:
She has 15 pigs, 12 chickens, and 18 ducks.
