Answer:
80
Step-by-step explanation:
f(3)=4(3)^3-3(3)^2+5(3)-16
f(3)=4(3*3*3)-3(3*3)+15-16
f(3)=4(27)-3(9)+15-16
f(3)=108-27+15-16
f(3)=81+15-16
f(3)=96-16
f(3)=80
Answer:
9.2
Step-by-step explanation:
So the 14 can be divided equally on both sides by the fact that the line cutting it at right angle bisects it.
Thus having 6 and 7 as the two shorter sides of a right angled triangle will help us get the radius( hypotenuse in this case) using the square root of the sum of the squares of both six and 7, the Pythagoras theory.
this leads to 9.2 as our answer
Answer:
x = 1, y = 3
Step-by-step explanation:
x = y - 2, so y = 4 (y - 2) -1
solve normally now
y = 4 (y - 2) -1
y = 4y - 8 - 1 (distribute)
y = 4y - 9 (simplify)
+9 -y -y +9
9 = 3y
3 = y
y - 2 = x
(3) - 2 = x
x = 1
Answer:
Step-by-step explanation:
Let
x -----> the number of yellow rose bushes
y -----> the number of red rose bushes
we know that
At least means "greater than or equal to"
----> inequality A
-----> inequality B
additionally
The number of roses cannot be a negative number
so
----> inequality C
----> inequality D
therefore
The restraints are
