Solve for y:
2y - 4 > \( \frac{y}{-7} \)

44% Answer Correctly
y > 1\(\frac{13}{15}\)
y > -\(\frac{10}{13}\)
y > -1
y > -1\(\frac{1}{11}\)

Solution

To solve this equation, repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the > sign and the answer on the other.

2y - 4 > \( \frac{y}{-7} \)
-7 x (2y - 4) > y
(-7 x 2y) + (-7 x -4) > y
-14y + 28 > y
-14y + 28 - y > 0
-14y - y > -28
-15y > -28
y > \( \frac{-28}{-15} \)
y > 1\(\frac{13}{15}\)


2

The formula for the area of a circle is which of the following?

78% Answer Correctly

a = π r

a = π d

a = π d2

a = π r2


Solution

The circumference of a circle is the distance around its perimeter and equals π (approx. 3.14159) x diameter: c = π d. The area of a circle is π x (radius)2 : a = π r2.


3

Which of the following expressions contains exactly two terms?

83% Answer Correctly

polynomial

binomial

monomial

quadratic


Solution

A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.


4

A coordinate grid is composed of which of the following?

91% Answer Correctly

all of these

x-axis

origin

y-axis


Solution

The coordinate grid is composed of a horizontal x-axis and a vertical y-axis. The center of the grid, where the x-axis and y-axis meet, is called the origin.


5

The dimensions of this cylinder are height (h) = 8 and radius (r) = 5. What is the surface area?

48% Answer Correctly
44π
130π
18π
48π

Solution

The surface area of a cylinder is 2πr2 + 2πrh:

sa = 2πr2 + 2πrh
sa = 2π(52) + 2π(5 x 8)
sa = 2π(25) + 2π(40)
sa = (2 x 25)π + (2 x 40)π
sa = 50π + 80π
sa = 130π
