F(2) = 20(1.25)^x
f(2) = 20(1.25)^2 - plug in 2 to x
f(2) = 20(1.5625) - calculate 1.25^2
f(2) = 31.25 - simplify
Because it's a right angle, you can determine that Angle ABC and Angle CBD=90 degrees. Therefore:
(2x+1)+33=90
2x+1=57
2x=56
x=28
Due to one of the postulates, or whatever (haven't done geometry in 2 yrs, forgive me), angles GJH and FJI are equal to each other. Therefore:
5x+12=6x-10
-x=-22
x=22
It is b because when you do that it is right
Let the length be x.
Length = x
Width = x + 7
Area = Length x Width = x (x + 7)
x(x + 7) = 170
x² + 7x - 170 = 0
Answer: x² + 7x - 170 = 0
Answer:
y = -10x +44
Step-by-step explanation:
Parallel lines will have the same slopes but different b values so we know that the base of this equation will be
y = -10x +b
To find b we must plus in the given coordinates and determine which value of b makes the statement true.
-6 = -10(5) + b
-6 = -50 + b
b = 56
Therefore the new equation will be:
y = -10x + 44
