What is (2^4)(2^0)?
- A.
2^4
- B.
2^5
- C.
2^3
- D.
4^0
Correct Answer
A. 2^4Explanation
The given expression (2^4)(2^0) can be simplified by using the rule of exponents which states that when multiplying two numbers with the same base, you add the exponents. In this case, 2^4 represents 2 raised to the power of 4, which is 16. Since any number raised to the power of 0 is equal to 1, 2^0 equals 1. Therefore, (2^4)(2^0) simplifies to 16 * 1, which is equal to 16.Rate this question:

What is the y-intercept of y = -4x + 1?
- A.
-1
- B.
1
- C.
4
- D.
-4
Correct Answer
B. 1Explanation
The y-intercept of a linear equation is the point where the line intersects the y-axis. In the given equation, y = -4x + 1, the y-intercept can be found by setting x = 0 and solving for y. When x = 0, the equation becomes y = 1. This means that the line intersects the y-axis at the point (0, 1). Therefore, the correct answer is 1.Rate this question:

What is 5!?
- A.
24
- B.
720
- C.
120
- D.
5
Correct Answer
C. 120Explanation
The correct answer is 120 because 5! (read as "5 factorial") means multiplying all positive integers from 1 to 5. Therefore, 5! is equal to 5 x 4 x 3 x 2 x 1, which equals 120.Rate this question:

What value of x will make "2x + 5 = 3x" a true statement?
- A.
1
- B.
-5
- C.
5
- D.
-1
Correct Answer
C. 5Explanation
To make the equation "2x + 5 = 3x" true, we need to find the value of x that satisfies the equation. By subtracting 2x from both sides of the equation, we get 5 = x. Therefore, the value of x that makes the equation true is 5.Rate this question:

What is the equation of a line with a slope of -2 and passing through (4, -1)?
- A.
Y = -2x - 7
- B.
Y = 2x + 7
- C.
Y = -2x + 7
- D.
Y = 2x - 7
Correct Answer
C. Y = -2x + 7Explanation
The equation of a line can be represented in the form y = mx + b, where m is the slope and b is the y-intercept. In this case, the slope is -2. Since the line passes through the point (4, -1), we can substitute these values into the equation. By solving for b, we find that b = 7. Therefore, the equation of the line is y = -2x + 7.Rate this question:

- C.
4
- D.
-9
Correct Answer
C. 4Explanation
The degree of a term in a polynomial is determined by the exponent of the variable. In this case, the term is -9x^4, where the exponent of x is 4. Therefore, the degree of -9x^4 is 4.Rate this question:

What is the factored form of w(x + y) - z(x + y)?
- A.
(w - z)(x + y)
- B.
(w + z)(x + y)
- C.
Wz(x + y)
- D.
(w - z)(x + y)(x + y)
Correct Answer
A. (w - z)(x + y)Explanation
The given expression can be factored by using the distributive property. By factoring out the common factor of (x + y), we get (w - z)(x + y).Rate this question:

- C.
0
- D.
0.33
Correct Answer
C. 0Explanation
The y-intercept of a linear equation represents the point where the line intersects the y-axis. In the equation y = 3x, when x is 0, the value of y will also be 0. Therefore, the y-intercept is 0.Rate this question:

What is (y^5)(y^0)?
- A.
Y^4
- B.
Y^0
- C.
Y^5
- D.
Y^6
Correct Answer
C. Y^5Explanation
When multiplying variables with the same base, you add their exponents. In this case, y is raised to the power of 5 and y is raised to the power of 0. Any number raised to the power of 0 is equal to 1. Therefore, y^0 equals 1. So, when multiplying y^5 and y^0, the result is y^5.Rate this question:

What is the equation of a line with a slope of -3 and a y-intercept of -1?
- A.
Y = -3x - 1
- B.
Y = -3x + 1
- C.
Y = 3x - 1
- D.
Y = 3x + 1
Correct Answer
A. Y = -3x - 1Explanation
The equation of a line with a slope of -3 and a y-intercept of -1 is y = -3x - 1. The slope-intercept form of a linear equation is y = mx + b, where m represents the slope and b represents the y-intercept. In this case, the slope is -3 and the y-intercept is -1, so the equation becomes y = -3x - 1.Rate this question:

What kind of slope does y = 3x + 1 have?
- A.
Zero
- B.
Negative
- C.
Undefined
- D.
Positive
Correct Answer
D. PositiveExplanation
The equation y = 3x + 1 represents a line with a positive slope. This means that as the value of x increases, the value of y also increases. The positive slope indicates that the line is ascending from left to right.Rate this question:

What is the degree of 2x^2 - x - 1?
- A.
2
- B.
0
- C.
1
- D.
-1
Correct Answer
A. 2Explanation
The degree of a polynomial is determined by the highest power of the variable in the expression. In this case, the highest power of x is 2, so the degree of 2x^2 - x - 1 is 2.Rate this question:

What is (3^5)/(3^3)?
- A.
3^(5/3)
- B.
3^2
- C.
3^15
- D.
3^8
Correct Answer
B. 3^2Explanation
To find the value of (3^5)/(3^3), we can use the rule of exponents which states that when dividing two numbers with the same base, we subtract the exponents. In this case, we have 3^5 divided by 3^3. Subtracting the exponents, we get 3^(5-3) which simplifies to 3^2. Therefore, the correct answer is 3^2.Rate this question:

If x = -28 and y = -61, what is " -x + 3(x - y) "?
- A.
-127
- B.
-71
- C.
71
- D.
127
Correct Answer
D. 127Explanation
The given expression is "-x + 3(x - y)". Substituting the given values of x and y, we get "-(-28) + 3((-28) - (-61))". Simplifying this expression further, we have "28 + 3(33)". Multiplying 3 with 33 gives us 99. Adding 28 and 99 together results in 127. Therefore, the answer is 127.Rate this question:
