Answer:
19.5 sq. inches
Step-by-step explanation:
This one is fairly simple. The area of a rhombus is the same as that of a parallelogram, which is side * height. In this case, we have 6.5 (side) *3 (height) = 19.5 sq. inches. Hope this helps!
1/4 hour is the same as 15 minutes. If it takes 15 minutes to paint 1/3, then it would take 45 minutes to paint the whole wall.
Answer:
y = -3x
Step-by-step explanation:
(a) Slope
y = mx + b
Choose points (-3, 9) and (3, -9)
m = (-9 - 9)/(3 – (-3))
m = -18/(3 + 3)
m = -18/6
m = -3
=====
(b) y-intercept
y = mx +b
Choose point (0,0).
0 = 0 + b
b = 0
=====
(c) Equation of line
y = mx + b
y = -3x
