Solve for x:
5x - 6 > \( \frac{x}{-2} \)
| x > -1\(\frac{11}{13}\) | |
| x > 2\(\frac{2}{15}\) | |
| x > 1\(\frac{1}{11}\) | |
| x > \(\frac{6}{13}\) |
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.
5x - 6 > \( \frac{x}{-2} \)
-2 x (5x - 6) > x
(-2 x 5x) + (-2 x -6) > x
-10x + 12 > x
-10x + 12 - x > 0
-10x - x > -12
-11x > -12
x > \( \frac{-12}{-11} \)
x > 1\(\frac{1}{11}\)
A coordinate grid is composed of which of the following?
origin |
|
all of these |
|
y-axis |
|
x-axis |
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.
A cylinder with a radius (r) and a height (h) has a surface area of:
2(π r2) + 2π rh |
|
π r2h2 |
|
π r2h |
|
4π r2 |
A cylinder is a solid figure with straight parallel sides and a circular or oval cross section with a radius (r) and a height (h). The volume of a cylinder is π r2h and the surface area is 2(π r2) + 2π rh.
What is 8a - 7a?
| 1a | |
| 56a2 | |
| a2 | |
| 1 |
To combine like terms, add or subtract the coefficients (the numbers that come before the variables) of terms that have the same variable raised to the same exponent.
8a - 7a = 1a
On this circle, line segment AB is the:
chord |
|
diameter |
|
circumference |
|
radius |
A circle is a figure in which each point around its perimeter is an equal distance from the center. The radius of a circle is the distance between the center and any point along its perimeter. A chord is a line segment that connects any two points along its perimeter. The diameter of a circle is the length of a chord that passes through the center of the circle and equals twice the circle's radius (2r).
