The Math — Module 2 (harder) section of the SAT practice test — 22 questions. Mark your answers, then press Finish at the bottom to see your score.

This is the same test the app serves as Practice Test 1. Working it here spends it: these questions will not be new when you take the test against the clock in the app.

The real SAT chooses your second module from how you did on the first, so both versions of Module 2 are here. In the app, your Module 1 result decides which one you take.

Nothing is marked while you work, just as on the real test. The answers and the worked explanations open when you finish. What you mark is kept in this browser, so closing the tab does not lose it.

Question 1

The function h is defined by h(x)=x2+x+53. What is the value of h(3)?

Show answer

Answer: C — 65

Substitute x=3: h(3)=32+3+53=9+3+53=65.

Question 2

∣2x+1∣=9

What is the positive solution to the given equation?

✓ Correct✗ Not correct
Show answer

Answer: 4

The equation ∣2x+1∣=9 gives 2x+1=9 or 2x+1=−9, so x=4 or x=−5. The positive solution is 4.

Question 3

The variables h and j are positive. Which expression is equivalent to (h3j−2)(h2j6)?

Show answer

Answer: B — h5j4

When powers with the same base are multiplied, their exponents are added. Thus, the expression becomes h3+2j−2+6=h5j4.

Question 4

The function f is defined by f(x)=4x−7, and the function g is defined by g(x)=f(x)+12. Which equation defines g?

Show answer

Answer: C — g(x)=4x+5

Adding 12 to f(x) gives g(x)=4x−7+12=4x+5.

Question 5

Marcus bikes at a speed of 12 miles per hour and drives at a speed of 40 miles per hour. He bikes for w hours and drives for 1 hour, covering a combined total of 124 miles. What is the value of w?

Show answer

Answer: B — 7

12w+40=124, so 12w=84 and w=7.

Question 6

At a music school, the ratio of electric guitars to acoustic guitars is 9 to 7. The school has 208 electric and acoustic guitars in all. How many more electric guitars than acoustic guitars does the school have?

Show answer

Answer: B — 26

The ratio contains 9+7=16 equal parts, so each part represents 208÷16=13 guitars. Electric and acoustic differ by 9−7=2 parts, so there are 2⋅13=26 more electric guitars than acoustic guitars.

Question 7

9x+15y=36
6x+10y=15

How many solutions does the given system of equations have?

Show answer

Answer: A — Zero

Multiplying the first equation by 23 gives 6x+10y=24. The second equation has the same left side but a different right side, so the system has no solution.

Question 8

A coach recorded the number of push-ups completed by each of five athletes during a fitness test. The table shows the number of push-ups completed by each athlete.

AthletePush-upsA30B34C28D32E26

A sixth athlete joins the group and completes 55 push-ups, and this result is included with the original five. How does the mean number of push-ups for all six athletes now compare with the mean for the original five athletes?

Show answer

Answer: A — The mean for the six athletes is greater than the mean for the five athletes.

The original five athletes have a mean of (30+34+28+32+26)/5=30 push-ups. Adding the sixth athlete’s 55 push-ups gives a total of 205 over 6 athletes, for a new mean of 2056, which is greater than 30.

Question 9

The scatterplot shows the mass, in tens of kilograms, of each of six crates and the delivery cost, in dollars, for each crate.

404244464850525456586001234567Delivery cost(dollars)Mass (tens of kilograms)

The line of best fit for the data shown has equation y=42.1+2.6x. A crate has a mass of 50 kilograms. Based on the line of best fit, what is the predicted delivery cost, in dollars?

✓ Correct✗ Not correct
Show answer

Answer: 55.1

The horizontal axis measures mass in tens of kilograms, so a crate of 50 kilograms corresponds to x=5. Substituting into the given line of best fit yields y=42.1+2.6(5)=42.1+13=55.1.

Question 10

ℓmP

Note: Figure not drawn to scale.

In the figure shown, lines ℓ and m are perpendicular and intersect at point P=(2,5). The slope of line ℓ is −34. Which equation represents line m?

Show answer

Answer: C — y=43x+73

A line perpendicular to a line of slope −34 has slope 43. Using point P=(2,5) gives 5=43(2)+b, so b=73 and m has equation y=43x+73.

Question 11

A robotics club has $30 to spend on gears and belts. The number of gears g and the number of belts b the club can buy are related by

2.25g+1.50b≤30.

Which combination of gears and belts could the club buy?

Show answer

Answer: B — 5 gears and 10 belts

Only 5 gears and 10 belts satisfy the inequality: 2.25(5)+1.50(10)=11.25+15=26.25≤30. Each other combination totals more than $30.

Question 12

−6−5−4−3−2−1123456−27−18−991827O

The graph shown could represent which of the following functions?

Show answer

Answer: A — f(x)=(x−3)2(x+3)

The graph touches the axis (double root) at x=3 and crosses at x=−3, matching (x−3)2(x+3).

Question 13

Two right rectangular prisms are similar. The smaller prism has dimensions 6 centimeters by 9 centimeters by 12 centimeters. The surface area of the larger prism is 1,300 square centimeters. What is the volume, in cubic centimeters, of the larger prism?

✓ Correct✗ Not correct
Show answer

Answer: 3000

The smaller prism has surface area 2(6⋅9+6⋅12+9⋅12)=468 square centimeters. The surface-area ratio is 1,300/468=25/9, so the linear scale factor is 5/3. Thus, the larger prism’s dimensions are 10, 15, and 20 centimeters, and its volume is (10)(15)(20)=3,000 cubic centimeters.

Question 14

Triangles ABC and DEF are similar, where A corresponds to D, B corresponds to E, and C corresponds to F. Angle C is a right angle, and the measure of angle D is 34∘. What is the measure of angle E?

Show answer

Answer: B — 56∘

Since A corresponds to D, angle A=34∘. Triangle ABC is a right triangle with the right angle at C, so angle A + angle B = 90∘, giving angle B=56∘. Since B corresponds to E, angle E=56∘.

Question 15

The quantity x increases by 20% and then decreases by 10%. The final amount is k% of the original amount. What is the value of k?

✓ Correct✗ Not correct
Show answer

Answer: 108

The overall factor is 1.20×0.90=1.08, so the final amount is 108% of the original. Thus k=108.

Question 16

(x−2)2+(y+1)2=41

The point (a,b) lies on the circle represented by the given equation and satisfies a+b=6. What is the greatest possible value of a?

Show answer

Answer: C — 9+572

Let u=a−2 and v=b+1. Then u2+v2=41 and u+v=5, so uv=−8 and u=5±572. Therefore, the greatest value of a=u+2 is 9+572.

Question 17

In right triangle QRS, angle S is a right angle.

tan⁡Q=6572

Based on the given equation, which of the following is equal to (sin⁡Q)(sin⁡R)+(cos⁡Q)(cos⁡R)?

Show answer

Answer: D — 9,3609,409

The tangent ratio gives leg lengths proportional to 65 and 72, so the hypotenuse is 652+722=97. The sine and cosine ratios for angles Q and R are reversed, so the expression is 65⋅72+72⋅65972=9,3609,409.

Question 18

px+4=3x+12

In the given equation, p is a constant. The equation has no solution. What is the value of p?

✓ Correct✗ Not correct
Show answer

Answer: 3

Rewriting as (p−3)x=8, the equation becomes 0=8 when p=3, which is never true. So the equation has no solution when p=3.

Question 19

y=−3x2+31x−41
y=x+c

In the given system of equations, c is a constant. In the xy-plane, the graphs of the given equations have exactly one point in common. What is the x-coordinate of that point?

Show answer

Answer: B — 5

The graphs intersect where −3x2+31x−41=x+c, or −3x2+30x−(41+c)=0. For exactly one point in common, this quadratic has a repeated root at x=−302(−3)=5.

Question 20

For x≠0, which expression is equivalent to (x+1)4−(x−1)4(x+1)2−(x−1)2?

Show answer

Answer: C — 2x2+2

Let A=(x+1)2 and B=(x−1)2. The quotient is A2−B2A−B=A+B=(x+1)2+(x−1)2=2x2+2.

Question 21

The table shows two values of x and their corresponding values of h(x), where h(x)=p(x)+4x−1 and p is a linear function. What is the y-intercept of the graph of y=p(x)?

xh(x)−2345
Show answer

Answer: A — (0,−5)

The table gives p(−2)=−13 and p(4)=11, so the slope of p is 4. Using p(4)=11 gives p(0)=−5, making the intercept (0,−5).

Question 22

The function f is defined by f(x)=ax2+bx+c, where a, b, and c are constants. For every value of x, f(x+1)−f(x)=6x+5. What is the value of f(2)−f(0)?

Show answer

Answer: D — 16

Expanding gives f(x+1)−f(x)=2ax+a+b, so a=3 and b=2. Therefore, f(2)−f(0)=4a+2b=16.

In the app the clock runs, you can pause and pick up where you left off, every question is explained afterwards, and your score is estimated on the test’s own scale. Extended time (1.5× or 2×) is there if you have an accommodation.
