Answer:
D. 5y^2 - 4y - 1
Step-by-step explanation:
Combine like terms:
(y^2 -y +1) +(4y^2 -3y -2)
= y^2(1 +4) +y(-1-3) +(1 -2)
= 5y^2 -4y -1
Answer:
12.04m = l
Step-by-step explanation:
We can use the Pythagorean theorem
a^2 + b^2 =c^2
where a and b are the legs and c is the hypotenuse
12^2 + 1 ^2 = l^2
144 + 1 = l^2
145 = l^2
Take the square root of each side
sqrt(145) = sqrt(l^2)
12.04159458 = l
To the nearest hundredth
12.04m = l
Answer:
The answer is C
Step-by-step explanation:
You can use the distance formula: d = sqrt((second x value - first x value)^2 + (second y value - first y value)^2):
answer : d = sqrt((3+2)^2+(6+6)^2) = 11.95826074 units
Perpendicular lines have slopes that are negative reciprocals of each other, so the equation of the line in point-slope form is:
Rewriting this in standard form,
