For lines to be parallel, they have to have the same slopes. For the equation given as Ax + By + C = 0, the slope is -A / B. Equating the slopes of the given equations of lines,
- (3 / -5) = - (2 / k)
The value of k is equal to -10/3.
Answer:
The N value represents a standard value of energy required to penetrate 30 cm into soil by percussion drilling. It is standardized as the energy of a falling hammer from a height of 0,76 m.
Step-by-step explanation:
Answer:
False
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 )
here m = - 
, hence
y = - x + c ← is the partial equation
to find c substitute (- 3, 5) into the partial equation
5 = 
+ c ⇒ c = 
y = - x + ← equation of line
Answer:
7
Step-by-step explanation:
The number of cells in a tile is 4. If colored alternately, there are 3 of one color and 1 of the alternate color. To balance the coloring, an even number of tiles is needed. Hence the board dimensions must be multiples of 4.
In the given range, there are 7 such boards:
4×4, 8×8, 12×12, 16×16, 20×20, 24×24, and 28×28
