Answer: 1296 cm³
Step-by-step explanation:
Since, the volume of a square pyramid is,
Where a = side of the square base,
h = height of the pyramid,
By the given diagram,
a = 18 cm,
h = 12 cm,
Hence, the volume of the given pyramid,
cube cm.
⇒ First option is correct.
y = 2x - 5
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
rearrange 2x - y = 6 into this form ( subtract 2x from both sides )
- y = - 2x + 6 ( multiply through by - 1 )
y = 2x - 6 ← in slope -intercept form with slope m = 2
Parallel lines have equal slopes
the partial equation is y = 2x + c
to find c substitute (2, - 1 ) into the partial equation
- 1 = 4 + c ⇒ c = - 1 - 4 = - 5
y = 2x - 5 ← equation of parallel line
Answer:
105 for all of them
Step-by-step explanation:
1) take 180-75, because of opposite angles.
105
2)again, 105 because we know the opposite angle is 75
3)105
again, opposite angles.
Answer:
Point form : (1/4,-1/5)
Equation form : x=1/4,y=-1/5
Step-by-step explanation: Solve for the first variable in one of the equations, then substitute the result into the other equation.
