Step-by-step explanation:
are 1 and 3, then their sum is 4 which is divisible by 4.
are 3 and 5, their sum is 8 which is divisible by 4.
Solve the system by graphing
{y = 7 - x the slope is -1 and the y intercept is 7
{x + 3y = 11 3y = -x+11 y = 1/3 x + 11/3 the slope is 1/3 and the y intercept is 11/3
The solution is x=5, y=2 you will need to graph
Classify the system without graphing
{2x + y = 3 y = -2x+3
{y = -2x - 1
These lines are parallel same slope different y intercept
C) Inconsistent System
Classify the system without graphing
{x + 3y = 9
{-2x - 6y = -18 divide by -2
x+3y = 9
same line
A) Dependent System
The answer is .48 cents per sock .96 cents per pair
Answer:
Step-by-step explanation:
A linear equation with two variables may appear in the form of Ax + By = C, and the resulting graph is always a straight line. The equation is more often in the form of y = mx+b, where m is the slope of the line of the corresponding figure and b is its Y-axis intercept, that is, the point where the line meets the Y-axis.
For example, 4x + 2y = 8 is a linear equation because it fits the desired structure. But for graphical and most other purposes, we often write this as y = - 2x + 4.
In this unit, on the basis of this linear equation, the equal sign is changed to the greater than a sign or less than sign, which is a new challenge in the operation of symbols.
1. LCD of 3/5 and 1/6 is 30
2. 3/7 - 1/14 = 6/14 - 1/14 = 5/14
3. 1/3 + 2/9 = 3/9 + 2/9 = 5/9
4. 8/15
5. 1 2/9 - 1 1/9
