Hello!
If the signs are the same, and you multiply or divide, the sign of the product or quotient will be positive. If the signs are different, the product or quotient will be negative.
Y=ax+b
a... slope
b... interception on the line y
you get the equation y=-1/2 *x + 12
Answer:
Step-by-step explanation:
hello :
the system is : y= 3x+4....(*)
y+6=3x....(**)
by (**) : y = 3x - 6
so : y= 3x+4
y= 3x - 6
means : 3x+4 = 3x - 6
4= -6.......(false)
conclusion : no reals solutions
This is an example of a nominal level of measurement.
In a nominal level of measurement, we are just classify the type of a variable. In this case, we are assigning a specific brand type to a particular cereal.
(0,30), (1,20)
(20-30)/(1-0) = -10/1 = -10 slope
We know y intercept is 30
Equation: y = -10x + 30
