Use the rational roots test.  The possible roots are: plus/minus 6,3,2,1

Use synthetic division and you will see that 3 is a root:

3 | 1 -3 -3 11 -6
   |    3  0  -9  6
   ____________
     1 0  -3   2 0

Use rational root again, to see that possible roots are: plus/minus 2,1

Try 2:

2 | 1 0 -3 -2
   |    2  4  2       
   _____________
     1  2  1  0

The above is x^2+2x+1 which is a perfect square: (x+1)^2

So we have the final factorization: (x-3)(x-2)(x+1)^2

So the roots are: 3, 2, -1
Where -1 is a double zero.

Y=-x+7
Allisa [31]
Question 1:
y=-x+7
y=2x-2

(-x+7)=2x-2
-x+7+x=2x-2+x
7=2x-2+x
7+2=2x-2+x+2
9=3x
9/3=3x/3
3=x

y=-x+7
y=-(3)+7
y=4

Question 2:
y-1=2x
y+2x=5

y-1=2x
y-1+1=2x+1
y=2x

(2x+1)+2x=5
2x+1+2x=5
4x+1=5
4x+1-1=5-1
4x=4
4x/4=4/4
x=1

y-1=2(1)
y-1+1=2+1
y=3

Answer: x=1 y=3

Solve please solve what does x mean
Zinaida [17]

Answer:

x=65

Step-by-step explanation:

find the angles of the small square by completing the outer ones so the one on the left the missing one is 68 and the other side is 47, so 180= 68+47 + x

180= 115 + x

x= 65

A whale is hunting at an elevation of −438 meters relative to sea level. How many meters below sea level is the whale?
Dafna1 [17]

Answer: The whale is 438 meters below the sea level.

Step-by-step explanation:

Given: A whale is hunting at an elevation of −438 meters relative to sea level.

Since in the scenario of height, a positive integer is used to represent the height (above a particular level) whereas a negative integer is used to represent the depth ( below a particular level).

If the whale is hunting at an elevation of −438 meters relative to sea level, then this means that the depth between the whale and the sea level is 468 meters.

Hence, the whale is 438 meters below the sea level.
