I have a few problems I need you to take a look at and tell me if I arrived at the right answer.

1. I am to use the intercepts to graph the equation x+3y=6
I used the formula y=mx+b using 3 and -6 for x I got these as my ordered pairs to graph (3, 1), (-6, 4)…Is this correct? I also got these two ordered pairs (0, 2) (3, 1)
2. Multiply -2/1*(-6/1): I got 12
3. Solve 3+4x<27 I got <6
4. Solve the compound inequality: 6>-4x+5 or 9 <(or equal to)-4x+2
My answer was (-oo,-7/4]u(-1/4,oo)
5. Is (5,2) a solution to 4x-2y=-6 I said no
6. Decide if the line is parallel, perpendicular or neither
5x+4y=2
4x-5y=4 I said neither
7. Solve using elimination: 5r-3s=11
3r+5s=61 I got (7, 8)
8. Graph using slope and y intercept: y=4/3x+3 I graphed (0, 3) and (3, 7)
9. Solve using elimination
2x+3y=1
4x+6y=2
I got 0…there is no solution

Hey I didn't see anybody doing it so I decided to help others! The answer to the quiz is:

1. C
2. C
3. A
4. C
5. C
6. C
7. D

For me it is correct but I do NOT know for all of you. I will not be held responsible for ANY of the misfortunes you get if you decide to do these answer. Good luck and pass the year!

Let's go through each problem and check your answers:

1. To graph the equation x + 3y = 6 using intercepts, we need to find the x-intercept and the y-intercept. To find the x-intercept, we set y = 0 and solve for x: x + 3(0) = 6 -> x = 6. So the x-intercept is (6, 0). To find the y-intercept, we set x = 0 and solve for y: 0 + 3y = 6 -> y = 2. So the y-intercept is (0, 2). Therefore, the correct ordered pairs to graph the equation are (6, 0) and (0, 2).

2. To multiply -2/1 * -6/1, we simply multiply the numerators and denominators: (-2 * -6) / (1 * 1) = 12 / 1 = 12. So your answer of 12 is correct.

3. To solve 3 + 4x < 27, we need to isolate x by subtracting 3 from both sides: 4x < 27 - 3 -> 4x < 24. To solve for x, we divide both sides by 4: x < 24/4 -> x < 6. So your answer of x < 6 is correct.

4. To solve the compound inequality 6 > -4x + 5 or 9 ≤ -4x + 2, we need to solve each inequality separately and then combine the solutions.
For 6 > -4x + 5: Subtract 5 from both sides: 6 - 5 > -4x + 5 - 5 -> 1 > -4x. Divide both sides by -4 (remember to flip the inequality sign): 1/-4 < -4x/-4 -> -1/4 < x.
For 9 ≤ -4x + 2: Subtract 2 from both sides: 9 - 2 ≤ -4x + 2 - 2 -> 7 ≤ -4x. Divide both sides by -4 (remember to flip the inequality sign): 7/-4 ≥ -4x/-4 -> -7/4 ≥ x.
So the combined solution is (-∞, -7/4] U (-1/4, ∞). Your answer is correct.

5. To check if (5, 2) is a solution to 4x - 2y = -6, substitute x = 5 and y = 2 into the equation: 4(5) - 2(2) = 20 - 4 = 16 ≠ -6. Therefore, (5, 2) is not a solution. Your answer of "no" is correct.

6. To determine if the two equations 5x + 4y = 2 and 4x - 5y = 4 are parallel, perpendicular, or neither, we need to compare their slopes. The slope-intercept form of an equation is y = mx + b, where m is the slope. In the first equation, the slope is -5/4, and in the second equation, the slope is 4/5. Since the slopes are not the same and not negative reciprocals of each other, the lines are neither parallel nor perpendicular. Your answer of "neither" is correct.

7. To solve the system of equations using elimination:
Multiply the first equation by 5 and the second equation by 3 to make the coefficients of s the same:
25r - 15s = 55
9r + 15s = 183
Add the two equations together: 34r = 238
Divide by 34: r = 7
Substitute r = 7 into one of the original equations, such as 5r - 3s = 11:
5(7) - 3s = 11
35 - 3s = 11
Subtract 35 from both sides: -3s = 11 - 35 -> -3s = -24
Divide by -3: s = 8
Therefore, the solution is (r, s) = (7, 8). Your answer is correct.

8. To graph the equation y = (4/3)x + 3 using slope and y-intercept:
The slope is 4/3, which means for every 3 units to the right on the x-axis, we go up 4 units on the y-axis. Start at the y-intercept, (0, 3), and plot this point. Then use the slope to find another point. From (0, 3), go 3 units to the right and 4 units up to get (3, 7). Plot this point as well. Draw a straight line through the two points. Your graph through (0, 3) and (3, 7) is correct.

9. To solve the system of equations using elimination:
Multiply the first equation by 2 and the second equation by -4 to make the coefficients of y the same:
4x + 6y = 2
-4x - 24y = -8
Add the two equations together: -18y = -6
Divide by -18: y = 1/3
Substitute y = 1/3 into one of the original equations, such as 2x + 3y = 1:
2x + 3(1/3) = 1
2x + 1 = 1
Subtract 1 from both sides: 2x = 0
Divide by 2: x = 0
Therefore, the solution is (x, y) = (0, 1/3). Your answer of 0 having no solution is incorrect.
