(-4)^-3 =
-4^-3 = 
Basically in this situation there is no difference whether parenthesis are used or not.
Step-by-step explanation:
4x2=−9x−4
Step 1: Subtract -9x-4 from both sides.
4x2−(−9x−4)=−9x−4−(−9x−4)
4x2+9x+4=0
For this equation: a=4, b=9, c=4
4x2+9x+4=0
Step 2: Use quadratic formula with a=4, b=9, c=4.
x=
−b±√b2−4ac
2a
x=
−(9)±√(9)2−4(4)(4)

x=

Answer:
y =
x + 2
Step-by-step explanation:
Find the reciprocal change the sign of the gradient (m=3):

so
y =
x + c
The intersect is 2, so c = 2
Final answer: y =
x + 2
Answer:
The correct is the little (B) 0.76
A) 176π in^3
The formula for the volume of a cylinder is πr^2h, so let’s substitute the values in.
π * 4^2 * 11
Now just solve.
π * 16 * 11
176π in^3
