Answer:
m = 7 n ( the '=' is meant to be the proportional sign)
Step-by-step explanation:
21 ÷ 3 = 7
35 ÷ 5 = 7
56 ÷ 8 = 7
The new equation after shifting will be:

Step-by-step explanation:
Function trnafomations upward and left are defined as:
Upward:
f(x) => f(x)+b where b is an integer
Left:
f(x) => f(x+b) where b is an integers
Given function is:

Shifting the function 5 units left

Shifting the function upward 2 units
So,

The new equation after shifting will be:

Answer:
let the number of cows = x
let the number of chickens = y
since there are 42 heads:
x + y = 42
and since a cow has 4 legs, and a chicken has 2
4x + 2y = 144
from first equation:
x + y = 42
x = 42 - y (now, we will substitute this in the second equation)
4(42 - y) + 2y = 144
168 - 4y + 2y = 144
2y = 168 - 144
2y = 24
y = 12
now, we know the number of chickens. we will replace y with 12 in the first equation since it is more simpler
x + 12 = 42
x = 30
So, there are 30 cows and 12 chickens

Answer:
Solve the equation for y. This will put the equation into slope intercept form.
y = mx + b
where m is the slope and b is the y-intercept
