Y = 7x + 3 Where does this line cross the y-axis?
-
(0,3)
-
(1,2)
-
(7,3)
-
(3,7)
Correct Answer
A. (0,3)Explanation
In the equation y = 7x + 3, to find where the line crosses the y-axis, you need to determine the y-coordinate when x is equal to 0. This is because the y-axis is where x = 0.
So, substitute x = 0 into the equation:
y = 7(0) + 3
y = 0 + 3
y = 3
The line crosses the y-axis at the point (0, 3).Rate this question:

Y = 27j - 7 - 7j. If y = 13 what will j be equal to?
Correct Answer
1Explanation
If y = 27j - 7 - 7j, and we know that y = 13, we can substitute y with 13 in the equation. Therefore, 13 = 27j - 7 - 7j. Simplifying this equation, we get 13 = 20j - 7. Adding 7 to both sides, we have 20 = 20j. Dividing both sides by 20, we find that j = 1.Rate this question:

Ben pays $40 per month to attend a weekly yoga class. His sister Ilene gets a discount at her yoga class and pays $35 per month. Over the course of one year, how much more money does Ben pay a year to attend his yoga class?
-
62
-
55
-
75
-
60
-
25
Correct Answer
A. 60Explanation
Ben pays $40 per month for his yoga class, while his sister pays $35 per month for hers. To calculate how much more money Ben pays a year, we need to find the difference between their monthly payments and multiply it by 12 (months in a year). The difference is $40 - $35 = $5. Therefore, Ben pays $5 more per month. Multiplying this by 12, we get $5 * 12 = $60. So, Ben pays $60 more a year to attend his yoga class.Rate this question:

F(x) = 17x - 30 Find f(2) - f(1)
Correct Answer
17Explanation
To find f(2) - f(1), we need to evaluate the function f(x) at x = 2 and x = 1, and then subtract the results.
Step 1: Find f(2)
Substitute x = 2 into the function: f(2) = (17 * 2) - 30 f(2) = 34 - 30 f(2) = 4
Step 2: Find f(1)
Substitute x = 1 into the function: f(1) = (17 * 1) - 30 f(1) = 17 - 30 f(1) = -13
Step 3: Calculate f(2) - f(1)
Subtract f(1) from f(2): f(2) - f(1) = 4 - (-13) f(2) - f(1) = 4 + 13 f(2) - f(1) = 17
Therefore, f(2) - f(1) = 17.Rate this question:

What is the slope of a straight line that connects the following points.(1,2) & (4,11)
Correct Answer
3Explanation
The slope of the line connecting the points (1, 2) and (4, 11) can be calculated using the formula:Slope = (y2 - y1) / (x2 - x1)where:x1 and y1 are the coordinates of the first point (1 and 2 in this case)x2 and y2 are the coordinates of the second point (4 and 11 in this case)Plugging in the values:Slope = (11 - 2) / (4 - 1)Slope = 9 / 3Slope = 3Therefore, the slope of the line connecting the points (1, 2) and (4, 11) is 3. This means that for every 3 units the line goes up vertically (y), it goes 1 unit to the right horizontally (x).Rate this question:

Solve for y in the equation: y – 13 = –3
-

-
-10
-
16
-
-16
Correct Answer
A. 10Explanation
The answer is 10.
Here's how to solve for y in the equation y – 13 = –3:
Add 13 to both sides of the equation to isolate y on one side:
y – 13 + 13 = –3 + 13
Simplify both sides:
y = 10
Therefore, the solution to the equation y – 13 = –3 is y = 10.

If a * b = 2 (a + b), then 5 * 2 is equal to:
-
3
-
10
-
14
-
20
Correct Answer
A. 14Explanation
In the equation a * b = 2 (a + b), where * represents a custom operation, the answer for 5 * 2 is not directly obtainable using conventional math operations like addition, subtraction, multiplication, or division.To solve for 5 * 2, we need to understand the logic behind the custom operation. Since the operation involves doubling the sum of a and b, it essentially multiplies both a and b by 2 and then adds them together.So, for 5 * 2:Double both 5 and 2: 2 * 5 = 10, 2 * 2 = 4Add the doubled values: 10 + 4 = 14Therefore, 5 * 2 in this custom operation equals 14.The other options are incorrect because:3: This result would be obtained if the operation simply involved multiplying a and b.10: This result would be obtained if the operation only doubled one of the numbers.20: This result is too high and doesn't follow the logic of the custom operation.Rate this question:

If 3x + 5 = 14, what is the value of x?
-

-
3
-
4
-
5
Correct Answer
A. 3Explanation
Think of this equation like a balanced scale. To find "x," we need to get it alone on one side. First, we subtract 5 from both sides to keep things balanced (3x = 9). Then, we divide both sides by 3, like splitting the weight equally, to find that x = 3.Rate this question:

-
8x - 2
-
8x + 2
Correct Answer
A. 10x - 2Explanation
Imagine this expression as a recipe with ingredients to combine. First, we "distribute" the 4 and 2, multiplying them with the terms inside the parentheses. This gives us 8x - 12 + 2x + 10. Then, we combine the "x" terms and the number terms separately, like grouping similar ingredients, to get 10x - 2.Rate this question:

-
10
-
14
Correct Answer
A. -14Explanation
This equation is like a puzzle where we need to uncover the value of "y." We start by distributing the 2 and 3 on each side, giving us 2y - 8 = 3y + 6. Then, we move the "y" terms to one side and the numbers to the other, keeping the equation balanced. This leads us to the solution: y = -14.Rate this question:

What is the slope of the line represented by the equation y = -2x + 5?
-
-2
-
2
-
5
-
-5
Correct Answer
A. -2Explanation
This equation is like a secret code for a line on a graph. The "-2" in front of the "x" tells us how steep the line is (its slope). The bigger the number, the steeper the line. In this case, the slope is -2, meaning the line goes downhill as you move from left to right.Rate this question:

If a rectangle has a length of (x + 3) and a width of (x - 2), what is its area?
-
2x + 1
-
X^2 + x - 6
-
X^2 + 5x - 6
-
2x + 6
Correct Answer
A. X^2 + x - 6Explanation
Imagine a rectangle with sides that have unknown lengths (represented by "x"). To find the area, we multiply the length and width. So, we multiply (x + 3) and (x - 2). This involves some careful expansion (like FOILing), and after combining terms, we get the area: x^2 + x - 6.Rate this question:
