Answer:
A= 12.5 inches²
Step-by-step explanation:
a=1/2bh
a=1/2(5)5
a=1/2(25)
a= 12.5
The answer will be 12/20=0.6
-x^5 - x^2+ 9
Here’s your answer
Marie is 5 years old
4m - 2l = -10 ------- x
l = 3m ---------------- y
sub y into x
4m - 2(3m) = -10
4m - 6m = -10
-2m = -10
m = -10/-2
m = 5 years old
Answer:
Perpendicular lines have slope that are negative reciprocals.
The slope of the perpendicular line is M = -1/3.
Step-by-step explanation:
(4,-1) --> X = 4, Y = -1, M = -1/3
y = Mx + b
-1 = (-1/3)*4 + b
-1 = (-4/3) + b
-3/3 = (-4/3) + b
-3 = -4 + 3b
1 = 3b
b = 1/3
y = (-1/3)X + 1/3
