Which is the graph of linear inequality
2y > x - 2
To graph the linear inequality 2y > x - 2, we need to rewrite it in slope-intercept form (y = mx + b), where m represents the slope and b represents the y-intercept.
First, let's isolate y on one side by dividing the entire inequality by 2:
y > (1/2)x - 1
Now we have the inequality in slope-intercept form. The slope is 1/2, which means the line will have a positive slope, and the y-intercept is -1, indicating that the line crosses the y-axis at (0, -1).
To graph this inequality, we draw a dotted line with a slope of 1/2 and a y-intercept of -1. Since the inequality is greater than (y >), we use a dotted line to show that points on the line itself are not included in the solution.
Next, we determine whether to shade above or below the line. Since y is greater than the line, we shade above the line. This shading represents the solution set of the inequality.
In summary, the graph of the linear inequality 2y > x - 2 is a dotted line with a positive slope of 1/2 and a y-intercept of -1, and the area above the line is shaded.

7+6 (mod 5) =
2+1 (mod 5) =
20 (mod 11) =
35 (mod 11) =
20 (mod 11) =
Answers:
33929======================================
Explanation:
7+6 = 13. Divide this over 5 to get 13/5 = 2 remainder 3. The quotient 2 is something we don't care about. We only worry about the remainder. Therefore 7+6 = 3 (mod 5)
-------------
2+1 = 3 (mod 5) for similar reasoning as above. 3/5 = 0 remainder 3.
-------------
20 = 9 (mod 11) since 20/11 = 1 remainder 9. Imagine you had 20 cookies and 11 friends. Each friend would get 1 whole cookie (quotient) and there could be 9 left over (remainder).
-------------
35/11 = 3 remainder 2
Or you could use repeated subtraction like so to find the remainder
35-11 = 24
24-11 = 13
13-11 = 2
The last result (2) is smaller than 11, so we stop here and this is the remainder.
Therefore, 35 = 2 (mod 11)
--------------
Here's another way to think of it. Consider you have $35 in your pocket. Let's say a store is selling trinkets for $11 each. We can pose these key questions:
What is the most number of trinkets you can buy?If you buy that max amount, how much will you have left over?The answer to the first question is 3 trinkets because 3*11 = 33 dollars is under the budget of $35. The amount left over is 35-33 = 2 dollars which is the remainder. It's not larger than 11, so we cannot buy any more trinkets at this point.

What is the slope of 78y+94x=80
y= 40/39-47x/30
x=40/47-39y/47
Step-by-step explanation:
The general equation of any linear equation is y = mx + c where m is yhe gradient.
78y + 94x =80
78y = -94x + 80
y = -94y/78 + 80/78
y = -47y/39 + 40/39
Therefore the slope is -47/39

solve for x -6x+14 <-28 or 9x+15 equal to -12
Answer:
i think the answer is D. there are no solutions
Answer:
A. x ≤ -3 or x > 7
Step-by-step explanation:
Solve the first equation.
-6x + 14 < -28
Subtract 14 from both sides.
-6x < -42
Divide both sides by -6. REMEMBER: when dividing an inequality by a negative number, flip the sign.
x > 7.
Solve the second equation.
9x + 15 ≤ -12
Subtract 15 from both sides.
9x ≤ -27
Divide both sides by 9.
x ≤ -3.
