You are having a hard time when it comes to an understanding some of the math questions you have covered so far throughout high school? If so, then the quiz below is precisely what you need to ensure that you understand everything that you learned. Why don’t you give it a shot and come back for more practice before you have to sit for your finals?

• 1.

### If f(x) = x^2 - 2x + 1, what is f(1)?

• A.

1

• B.

-4

• C.

0

• D.

4

C. 0
Explanation
To find f(1), we substitute 1 into the function f(x) = x^2 - 2x + 1. So, f(1) = 1^2 - 2(1) + 1 = 1 - 2 + 1 = 0. Therefore, the answer is 0.

• 2.

### If the side of a square is of length (x + 5), what is its area?

• A.

X^2 - 10x + 25

• B.

X^2 - 25

• C.

X^2 + 10x + 25

• D.

X^2 + 25

C. X^2 + 10x + 25
Explanation
The area of a square is equal to the side length squared. In this case, the side length is (x + 5), so the area of the square is (x + 5)^2. Expanding this expression gives us x^2 + 10x + 25. Therefore, the correct answer is x^2 + 10x + 25.

Rate this question:

• 3.

### If f(x) = 1/(x - 1) what is f(0)?

• A.

1

• B.

0

• C.

-1

• D.

Undefined

C. -1
Explanation
The function f(x) is defined as 1/(x-1). To find f(0), we substitute 0 into the function for x. Therefore, f(0) = 1/(0-1) = 1/(-1) = -1.

Rate this question:

• 4.

### What is the graph of y = 7x - 1?

• A.

A Line

• B.

A Circle

• C.

A Parabola

• D.

An Ellipse

A. A Line
Explanation
The equation y = 7x - 1 represents a linear function, where the graph is a straight line. The coefficient of x is 7, indicating that for every increase of 1 in x, y will increase by 7. The constant term -1 indicates that the line will intersect the y-axis at -1. Therefore, the graph of y = 7x - 1 is a line.

Rate this question:

• 5.

### What value of y makes y/(-10) = 100 a true statement?

• A.

100

• B.

-1000

• C.

-100

• D.

900

B. -1000
Explanation
To find the value of y that makes the equation true, we can solve for y by multiplying both sides of the equation by -10. This gives us y = 100 * -10 = -1000. Therefore, the value of y that makes the equation true is -1000.

Rate this question:

• 6.

### What is 1/6 in decimal form?

• A.

0.17

• B.

1.6

• C.

6.1

• D.

0.1666

D. 0.1666
Explanation
The correct answer is 0.1666 because when we divide 1 by 6, we get a repeating decimal of 0.1666.

Rate this question:

• 7.

### What values of x make (2x - 3)(3x + 1) = 0 a true statement?

• A.

-3/2 And -1/3

• B.

-3/2 And 1/3

• C.

3/2 And 1/3

• D.

3/2 And -1/3

D. 3/2 And -1/3
Explanation
To find the values of x that make the given statement true, we need to solve the equation (2x - 3)(3x + 1) = 0. This equation will be true if either of the factors equals zero. Setting 2x - 3 = 0, we can solve for x to find x = 3/2. Setting 3x + 1 = 0, we can solve for x to find x = -1/3. Therefore, the values of x that make the statement true are 3/2 and -1/3.

Rate this question:

• 8.

### What is x^3 - x in factored form?

• A.

X(x + 1)(x + 1)

• B.

X(x - 1)(x - 1)

• C.

(x + 1)(x - 1)

• D.

X(x - 1)(x + 1)

D. X(x - 1)(x + 1)
Explanation
The given expression, x^3 - x, can be factored as x(x - 1)(x + 1). This can be determined by looking for common factors and using the distributive property. The expression can be rewritten as x(x^2 - 1), and then further factored as x(x - 1)(x + 1) by recognizing the difference of squares pattern.

Rate this question:

• 9.

### What is the area of a trapezoid that has bases of 10 feet and 14 feet and a height of 8 feet?

• A.

96 Square Feet

• B.

144 Square Feet

• C.

48 Square Feet

• D.

192 Square Feet

A. 96 Square Feet
Explanation
The area of a trapezoid is calculated by multiplying the average of the lengths of the bases by the height. In this case, the average of the lengths of the bases is (10 + 14) / 2 = 12 feet. Multiplying this by the height of 8 feet gives us an area of 12 * 8 = 96 square feet.

Rate this question:

• 10.

### What is the x-intercept of 4x + 2y = -8?

• A.

(2, 0)

• B.

(-2, 0)

• C.

(0, 2)

• D.

(0, -2)

B. (-2, 0)
Explanation
The x-intercept of a linear equation represents the point where the line crosses the x-axis. To find the x-intercept, we set y = 0 and solve for x. In this equation, if we substitute y = 0, we get 4x + 2(0) = -8, which simplifies to 4x = -8 and x = -2. Therefore, the x-intercept is (-2, 0).

Rate this question:

• 11.

### If x = 1, what is y = 2^x?

• A.

2

• B.

0

• C.

2-Jan

• D.

1

A. 2
Explanation
When x is equal to 1, the equation y = 2^x can be simplified as y = 2^1, which is equal to 2. Therefore, the value of y is 2 when x is 1.

Rate this question:

• 12.

### How much interest is earned if \$2500 is invested for 25 years at 8% simple interest?

• A.

500

• B.

50000

• C.

2500

• D.

5000

D. 5000
Explanation
If \$2500 is invested for 25 years at 8% simple interest, the interest earned can be calculated using the formula: Interest = Principal * Rate * Time. Plugging in the values, we get: Interest = \$2500 * 0.08 * 25 = \$5000. Therefore, the correct answer is 5000.

Rate this question:

• 13.

### If x = -4 and y = 5, what is (x^4)*(y^2)?

• A.

-6400

• B.

6400

• C.

1280

• D.

-1280

B. 6400
Explanation
When we substitute the given values of x = -4 and y = 5 into the expression (x^4)*(y^2), we get (-4^4)*(5^2). Simplifying this, we have (256)*(25) which equals 6400. Therefore, the correct answer is 6400.

Rate this question:

• 14.

### What is 5(4x - 1) + 9x when simplified?

• A.

11x - 1

• B.

29x - 5

• C.

29x - 1

• D.

11x - 5

B. 29x - 5
Explanation
To simplify the expression 5(4x - 1) + 9x, we need to distribute the 5 to both terms inside the parentheses. This gives us 20x - 5 + 9x. Combining like terms, we get 29x - 5. Therefore, the correct answer is 29x - 5.

Rate this question:

• 15.

### If x = 0, what is y = 2^x?

• A.

2-Jan

• B.

2

• C.

0

• D.

1

D. 1
Explanation
When x is equal to 0, any number raised to the power of 0 is equal to 1. Therefore, when x = 0, y = 2^0 = 1.
