Simplify: (-12) + (-3)

1) Take care of double signs. If the signs do not match, they simplify to a negative (-); if they do match, they simplify to a (+). (-12) + (-3) simplifies to... -12 - 3. 2) Now do I ADD or SUBTRACT? **If signs are alike, add and keep the sign **If signs are different, subtract and keep the sign of the larger number. -12 - 3 simplifies to... -15

### Subject: Basic Math

Two sides of a triangle measure 3 inches and 4 inches. If the perimeter is 10 inches, what type of triangle is it?

1) We known that the two known sides plus the unknown side (x) equal 10 inches. 3 + 4 + x = 10 2) Subtract 3 and 4 from 10 to find the remaining side length. 10 - 3 - 4 = x 3) x = 3 inches

### Subject: Algebra

Sketch the graph of the line. y = $$\frac{7}{2}$$x - 2

1) Identify the parts of the equation: $$\frac{7}{2}$$ = slope (m); - 2 = y-intercept (which means the line you are creating passes through the - 2 on the y-axis) 2) Plot the y-intercept (- 2) on the y axis 3) From that - 2 point, follow what "m" is telling you to do... $$\frac{rise}{run}$$... move 7 units up and 2 units to the right 4) Connect the dots!
