The area of a triangle is 1/2 of base times height
for ΔPQS, the base is PS=6, the area is 16.5, so the height is 16.5×2÷=5.5
the height of the triangles is also the height of the trapezoid.
Erin score 1/3 of the attempts, while Lauren scored 1/4 of the attempted shots. 1/3 is greater 1/4, so Erin was the most successful.
1/3 > 2/8 ; Erin
y = - 4x - 2
the equation of a line in slope-intercept form is
y = mx + c ( m is the slope and c the y-intercept )
y = - 4x - 5 is in this form
with slope m = - 4
• Parallel lines have equal slopes
y = - 4x + c ← is the partial equation
To find c substitute (- 2, 6 ) into the partial equation
6 = 8 + c ⇒ c = 6 - 8 = - 2
y = - 4x - 2 ← equation of parallel line
The rate will be:
(area mowed)/(time taken)
