In all the given answer choices, we have the angle measure B. Considering the interior angle of B in the right triangle ABC above, AC is the opposite side an... |
# How do you solve and graph 5-(x+4)<= -3?
Jul 25, 2018
$x \ge 4$
#### Explanation:
$5 - \left(x + 4\right) \le - 3$
Distribute the negative sign on the left side:
$5 - x - 4 \le - 3$
Simplify:
$1 - x \le - 3$
Add $\textcolor{b l u e}{x}$ to both sides:
$1 - x \quad \textcolor{b l u e}{+ \quad x} \le - 3 \quad \... |

The volume of a box is: V = abc, where a, b, c is its dimension. Therefore, the volume of a cube is equal to V = a*a*a = a^3, where a is the side length of the cube.The surface area of a cube is equal to the... |
Example OAF.BRF.3 : $R(x) = \frac {x-2}{(x^2+1)(x+1)}$.
Notice: $h=2$ , and $k = -1$.
Draw a mapping diagram and graph of $R$ yourself, or consider the GeoGebra figures and table below.

This article for teachers describes how number arrays can be a useful reprentation for many number concepts. Which is quicker, counting up to 30 in ones or counting up to in tens? How might you show them in a picture, with things, with numbers and symbols? Think of a number, sq... |
Recall from the Linear Lagrange Interpolating Polynomials page that given two points, $(x_0, y_0)$ and $(x_1, y_1)$ where $x_0$ and $x_1$ are distinct, we can construct a line $P_1$ that passes through these points. We also saw that we could approximate a function with this line that also passes through these two point... |

We will encounter non-quadratic equations that are quadratic in form. We can create a quadratic equation by making a simple substitution. We can then solve the quadratic equation using the quadratic formula. When done, we substitute once more to obtain a solution in terms of the original variable involved.
