Which points are on the graph of the equation -3x + 6y + 5 = -7Select all that apply.
- A.
(-3, 6)
- B.
(-2, 0)
- C.
(0, -2)
- D.
(6, -3)
- E.
(8, 2)
Correct Answer(s)
C. (0, -2)
E. (8, 2)Explanation
The equation -3x + 6y + 5 = -7 can be simplified to -3x + 6y = -12. To find the points on the graph, we can substitute the x and y values from each given point into the equation and check if it satisfies the equation. Substituting (0, -2) gives -3(0) + 6(-2) = -12, which is true. Substituting (8, 2) gives -3(8) + 6(2) = -12, which is also true. Therefore, the points (0, -2) and (8, 2) are on the graph of the equation.Rate this question:

Which one of the below does NOT have an x-intercept?
- A.
Y = -2x + 3
- B.
2x + 4y = 12
- C.
Y = -7
- D.
X = 4
Correct Answer
C. Y = -7Explanation
The equation y = -7 represents a horizontal line with a y-coordinate of -7. Since it is a horizontal line, it does not intersect the x-axis and therefore does not have an x-intercept.Rate this question:

- E.
-7
- F.
0
Correct Answer(s)
C. -1
D. 4
F. 0Explanation
The inequality given is 3(x + 2) - 7 < 5x + 3. To solve this inequality, we can start by simplifying both sides of the inequality. Distributing the 3 on the left side gives us 3x + 6 - 7 < 5x + 3. Simplifying further, we have 3x - 1 < 5x + 3. Next, we can subtract 3x from both sides to isolate the variable. This gives us -1 < 2x + 3. Then, we can subtract 3 from both sides to get -4 < 2x. Finally, dividing both sides by 2 gives us -2 < x. So, the solution set to the inequality is x > -2. Therefore, the values -1, 4, and 0 are all part of the solution set.Rate this question:

Four friends are planning a party at a skating rink. The group must pay $3 for each person attending the party and have purchased $36 worth of snacks. If each friend contributes $21 to pay for the party, what is the maximum number of people that can attend the party?
- A.
16
- B.
19
- C.
28
- D.
48
Correct Answer
A. 16Explanation
Each person attending the party must pay $3, and the friends have contributed a total of $21. Therefore, they can pay for a maximum of $21/$3 = 7 people. Additionally, they have purchased $36 worth of snacks. So, the total amount of money available to pay for the party is $21 + $36 = $57. Since each person attending the party costs $3, the maximum number of people that can attend the party is $57/$3 = 19. Therefore, the correct answer is 19.Rate this question:

Find the x-intercept for the equation y = 2x-6X- intercept is (________, 0)*Only type what you would put in the blank
Correct Answer
3, x=3, (3,0)Explanation
The x-intercept of an equation represents the point where the graph of the equation intersects the x-axis. To find the x-intercept, we set y equal to zero and solve for x. In this equation, y = 2x - 6, we can set y = 0 and solve for x. By substituting 0 for y, we get 0 = 2x - 6. Solving this equation, we find that x = 3. Therefore, the x-intercept is (3, 0).Rate this question:

A store sells ropes in different lengths. This table shows the weights of rope with different lengths. Which equation represents the relationship between the length of the rope (L) in feet and weight (w), in ounces?
- A.
W = L - 3
- B.
W = L + 6
- C.
W = 0.75(L)
- D.
W = 1.2(L)
Correct Answer
C. W = 0.75(L)Explanation
The equation w = 0.75(L) represents the relationship between the length of the rope (L) in feet and weight (w) in ounces. This equation implies that the weight of the rope is 0.75 times the length of the rope.Rate this question:

What is the solution to the system?y = x + 63x + 2y = 2
- A.
(-4, 7)
- B.
(-2, 4)
- C.
(2, 8)
- D.
(4, 10)
Correct Answer
B. (-2, 4)Explanation
The correct answer is (-2, 4) because when we substitute the values of x and y into the system of equations, we get the following:
y = x + 6
4 = -2 + 6
4 = 4
This shows that the values (-2, 4) satisfy both equations in the system.Rate this question:

Which of the below are the graph for 3x + 6y = 9
- A.
A
- B.
B
- C.
C
- D.
D
Correct Answer
B. BExplanation
The correct answer is B because it represents the graph of the equation 3x + 6y = 9. The equation is in standard form, where the coefficients of x and y are not equal. This means that the graph will be a straight line. By rearranging the equation to y = (-1/2)x + 3/2, we can see that the slope is -1/2 and the y-intercept is 3/2. This matches the equation of the line in graph B, confirming that it is the correct representation of the equation.Rate this question:

The length of a rectangular garden is 7 more yards that it's width. The area of the garden is 60 square yards. What is the length of the garden?
- A.
5 yards
- B.
6 yards
- C.
12 yards
- D.
13 yards
Correct Answer
C. 12 yardsExplanation
Let's assume the width of the garden is x yards. According to the given information, the length of the garden is 7 more yards than its width, which means the length is x + 7 yards. The area of a rectangle is calculated by multiplying its length and width, so we have the equation (x)(x + 7) = 60. By solving this equation, we find that x = 5. Therefore, the width of the garden is 5 yards and the length is 5 + 7 = 12 yards.Rate this question:

The zeros of a quadratic equation are the values of x where the equation equals zero. In this case, the quadratic equation has zeros at x = -2 and x = 1. These values can be found by setting the quadratic equation equal to zero and solving for x. The other values (-1, 2, and -1.5) are not zeros of the quadratic equation.Rate this question:

Sue earns $2 for each CD that she sells and $2.50 for each DVD that she sells. Sue earned a total of $950 last week. Given that Sue sold 305 CD's last week, how many DVD's did she sell?
- A.
94
- B.
136
- C.
211
- D.
258
Correct Answer
B. 136Explanation
Sue earns $2 for each CD and $2.50 for each DVD sold. Let's assume she sold x DVDs. The total amount she earned can be calculated as 2(305) + 2.50(x) = 950. Simplifying this equation gives us 610 + 2.50x = 950. By subtracting 610 from both sides, we get 2.50x = 340. Dividing both sides by 2.50 gives us x = 136. Therefore, Sue sold 136 DVDs.Rate this question:

An equilateral triangle has a perimeter of 54 inches. If each side measures (2x + 6) inches, what is the value of x?
- A.
6
- B.
18
- C.
24
- D.
31
Correct Answer
A. 6Explanation
In an equilateral triangle, all sides are equal in length. Therefore, if each side measures (2x + 6) inches, the perimeter of the triangle would be 3 times that length. Since the perimeter is given as 54 inches, we can set up the equation 3(2x + 6) = 54 and solve for x. Simplifying the equation gives 6x + 18 = 54. Subtracting 18 from both sides gives 6x = 36. Dividing both sides by 6 gives x = 6. Therefore, the value of x is 6.Rate this question:

Which of the below is the correct factoring for the expression?
- A.
(x + 6) (x - 2)
- B.
(x - 6) (x + 2)
- C.
(3x - 2) (x + 2)
- D.
(3x + 2) (x - 2)
Correct Answer
C. (3x - 2) (x + 2)Explanation
The given expression is (x + 6) (x - 2). To factorize this expression, we need to find two binomials whose product is equal to the given expression. The correct factoring is (3x - 2) (x + 2) because when we multiply these two binomials, we get (3x * x) + (3x * 2) + (-2 * x) + (-2 * 2) which simplifies to 3x^2 + 6x - 2x - 4. This is equal to the original expression (x + 6) (x - 2), confirming that (3x - 2) (x + 2) is the correct factoring.Rate this question:

The graph of which function has x-intercepts of (-4, 0) and (7, 0)
- A.
Y = (x - 4) (x - 7)
- B.
Y = (x + 4) (x + 7)
- C.
Y = (x - 4) (x + 7)
- D.
Y = (x + 4) (x - 7)
Correct Answer
D. Y = (x + 4) (x - 7)Explanation
The correct answer is y = (x + 4) (x - 7) because this function has x-intercepts of (-4, 0) and (7, 0). When the value of x is -4, the first factor (x + 4) becomes 0, resulting in y = 0. Similarly, when the value of x is 7, the second factor (x - 7) becomes 0, resulting in y = 0. Therefore, both x-intercepts are satisfied by this function.Rate this question:
