## Best **CLEP College **Math Prep Resource for 2021

## Answers:

1- **C**

Plugin the values of \(x\) and \(y\) provided in the choices into both equations. Let’s start with \(2x+2y=2\):

A.\((1,3) : 2x+2y=2→2+6≠2\)

B.\((2,4): 2x+y=2→4+8≠2\)

C.\((2,-1) :2x+2y=2→4+(-2)=2\)

D.\((4,-6): 2x+2y=2→12+(-12)≠2\)

E.\((1,-6): 2x+2y=2→2+(-12)≠2\)

Only choice C is correct.

2- **A**

If \(f(x)=3x+4(x+1)+2\), then find \(f(4x)\) by substituting \(4x\) for every \(x\) in the function. This gives: \(f(4x)=3 (4x)+ 4(4x+1)+2\)

It simplifies to: \(f(4x)=3 (4x)+4(4x+1)+2=12x+16x+4+2=28x+6\)

3-** C**

First, find the equation of the line. All lines through the origin are of the form \(y=mx\), so the equation is \(y=\frac{1}{3} x\). Of the given choices, only choice C (9,3), satisfies this equation:

\(y=\frac{1}{3} x→3=\frac{1}{3} (9)=3 \)

4- **C**

\((3n^2+2n+6)-(2n^2-4)\). Add like terms together: \(3n^2-2n^2=n^2, 2n\) doesn’t have like terms. \(6-(-4)=10\), Combine these terms into one expression to find the answer: \(n^2+2n+10\)

5- **C**

Simplify and solve for \(x\) in the equation. \(4(x+1)=6(x-4)+20, 4x+4= 6x-24+20, 4x+4=6x-4\). Subtract \(4x\) from both sides: \(4=2x-4\), Add 4 to both sides: \(8=2x, 4=x\)

6- **A**

To rewrite \(\frac{1}{\frac{1}{x-5}+\frac{1}{x+4}}\), first simplify \(\frac{1}{x-5}+\frac{1}{x+4}\).

\(\frac{1}{x-5}+\frac{1}{x+4}=\frac{1(x+4)}{(x-5)(x+4)}+\frac{1(x-5)}{(x+4)(x-5)}=\frac{(x+4)+(x-5)}{(x+4)(x-5)}\)

Then: \(\frac{1}{\frac{1}{x-5}+\frac{1}{x+4}}=\frac{1}{\frac{(x+4)+(x-5)}{(x+4)(x-5)}}=\frac{(x-5)(x+4)}{(x-5)+(x+4)}\). (Remember, \(\frac{1}{\frac{1}{x}}=x)\)

This result is equivalent to the expression in choice A.

7- **B**

Since (0,0) is a solution to the system of inequalities, substituting 0 for \(x\) and 0 for \(y\) in the given system must result in two true inequalities. After this substitution, \(y< c – x\) becomes \(0x+b\) becomes \(0>b\). Hence, a is positive and b is negative.

Therefore, \(c>b\).

8- **D**

\(3x+10=46→3x=46-10=36→x=\frac{36}{3}=12 \)

9- **B**

The input value is 5. Then: \(x=5. f(x)=x^2-3x→ f(5)=5^2-3(5)=25-15=10 \)

10- **B**

To solve this problem, first recall the equation of a line: \(y=mx+b\)

Where \(m=\)slope. \(y=y\)-intercept

Remember that slope is the rate of change that occurs in a function and that the y-intercept is the \(y\) value corresponding to \(x=0\).

Since the height of John’s plant is 5 inches tall when he gets it. Time (or \(x\)) is zero. The plant grows 3 inches per year. Therefore, the rate of change of the plant’s height is 3. The y-intercept represents the starting height of the plant which is 5 inches.

11- **C**

Multiplying each side of \(\frac{4}{x}=\frac{12}{x-8}\) by \(x(x-8)\) gives \(4(x-8)=12(x)\), distributing the 4 over the values within the parentheses yields \(x-8=3x\) or \(x=-4\).

Therefore, the value of \(\frac{x}{2}=\frac{-4}{2}=-2\).

12- **D**

Given the two equations, substitute the numerical value of a into the second equation to solve for \(x\). \(a=\sqrt{3}, 4a=\sqrt{4x}\)

Substituting the numerical value for a into the equation with \(x\) is as follows.

\(4(\sqrt{3})=\sqrt{4x}\), From here, distribute the \(4\). \(4\sqrt{3}=\sqrt{4x}\)

Now square both side of the equation. \((4\sqrt{3})^2=(\sqrt{4x})^2\)

Remember to square both terms within the parentheses. Also, recall that squaring a square root sign cancels them out. \(4^2 \sqrt{3}^2=4x, 16(3)=4x, 48=4x, x=12\)

13- **D**

In the figure angle A is labeled \((3x-2)\) and it measures \(37\). Thus, \(3x-2=37\) and \(3x=39\) or \(x=13\). That means that angle B, which is labeled \((5x)\), must measure \(5×13=65\).

Since the three angles of a triangle must add up to \(180, 37+65+y-8=180\), then:

\(y+94=180→y=180-94=86\)

14- **C**

Let \(x\) be all expenses, then \(\frac{22}{100} x=$660 →x=\frac{100×$660}{22}=$3,000\)

Mr. Jones spent for his rent: \(\frac{ 27}{100}×$3,000=$810\)

15- **A**

The amount of money for \(x\) bookshelf is: \(200x\), Then, the total cost of all bookshelves is equal to: \(200x+600\), The total cost, in dollar, per bookshelf is: \(\frac{Total \ cost}{number \ of \ items}=\frac{200x+600}{x}\)

16- **B**

It is given that g(5)=4. Therefore, to find the value of f(g(5)), then f(g(5))=f(4)=6

17- **A**

Area of the triangle is: \(\frac{1}{2}\) AD\(×\)BC and AD is perpendicular to BC. Triangle ADC is a

(\30^\circ-60^\circ- 90^\circ\) right triangle. The relationship among all sides of right triangle \(30^\circ-60^\circ- 90^\circ\) is provided in the following triangle: In this triangle, the opposite side of \(30^\circ\) angle is half of the hypotenuse. And the opposite side of \(60^\circ\) is opposite of \(30^\circ×\sqrt{3}\)

CD=6, then AD\(=6×\sqrt{3}\)

Area of the triangle ABC is: \(\frac{1}{2}\) AD\(×\)BC \(= \frac{1}{2} 6\sqrt{3}×12=36\sqrt{3}\)

\(\img{https://appmanager.effortlessmath.com/public/images/questions/mmm.png

}\)

18- **C**

\(6∎28=\sqrt{6^2+28}= \sqrt{36+28}=\sqrt{64}=8\)

19- **D**

The union of A and B is: \(A∪B={1,2,4,8,12,16,24,32,48}\). There are \(9\) elements in \(A∪B\).

20- **D**

Solve the system of equations by elimination method.

\(\cfrac{\begin{align} 3 x – 4 y = – 20 \\ – x + 2 y = 10 \end{align}}{} \)

Multiply the second equation by 3, then add it to the first equation.

\(\cfrac{\begin{align} 3 x – 4 y = – 20 \\ 3(- x + 2 y = 10) \end{align}}{} ⇒\)

\(\cfrac{\begin{align} 3 x – 4 y = – 20 \\ -3 x + 6 y = 30) \end{align}}{} ⇒\)add the equations \(2𝑦=10⇒𝑦=5\)
