Answer:
y = -5x + 21
Step-by-step explanation:
perpendicular lines have slopes that are negative reciprocals.
The given line has a slope of 1/5, so the perpendicular line will have a slope of -5.
y = -5x + B
-4 = -5(5) + B
B = -4 + 25 = 21
y = -5x + 21
To divide fractions, you flip the denominator and then multiply it by the numerator.
-6 / 5 x (-25 / 3)
Multiply straight across; the negative cancels out.
150 / 15
This can be reduced to 15, which is its simplest form.
Answer:
a = 14 km
Step-by-step explanation:
The area of a triangle is
A = 1/2 bh where b is the base and h is the height
112.7 = 1/2 ( a) 16.1
112.7 = 8.05a
Divide each side by 8.05
112.7/8.05 = a
14 =a
a = 14 km
She used two trapezoids.
She put one trapezoid on top and one on the bottom.
The shape she ends up making is a hexagon.
= 36 x^6 / 9 x^8
= 4 / x^2
Its A
