One-eighth represents one part of a whole that consists of eight units, but one-twelfth represents one part of a whole that consists of 12 units. Fractions are made up of numerators and denominators. Numerators are the top numbers and denominators are the bottom numbers. The numerator is the number that represents the part of a whole. The denominator is the total number of parts.
Answer:
y = - 0.5x
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (- 4, 2) and (x₂, y₂ ) = (2, - 1) ← 2 points on the line
m = = = = - 0.5
The line crosses the y- axis at (0, 0 ) ⇒ c = 0
y = - 0.5x + 0 . that is
y = - 0.5x
Answer:
C
Step-by-step explanation:
Perimeter of a triangle is the sum of all the sides.
A triangle has 3 sides, so if we add up all the 3 sides lengths <em>(given as expressions here)</em> of the triangle, we will have the perimeter.
Perimeter =
<em>Now combining like terms we have:</em>
<em></em>
Answer choice C is the correct one.
