Answer:
(B)(negative 2) (4)
Step-by-step explanation:
The arrow on the number line ended at negative 8 (-8).
Given the options:
(A) (negative 3) (4) =(-3)(4)=-12
(B)(negative 2) (4) =(-2)(4)=-8
(C) (2)(4)=8
(D)(3)(4)=12
The expected product is -8 since that is where the arrow ended. Therefore, the product that is modeled by the number line is that which gives a result of -8. The correct option is B.
(B)(negative 2) (4) =(-2)(4)=-8
Answer:
29274
Step-by-step explanation:
Because 17*14=238 and 238*123=29274
Answer:
x=15
Step-by-step explanation:
3(x-5)=30
First, you would distribute the three to the x and the negative five.
3x-15=30
Then you would add 15 to the 15 to cancel it and to the 30 to make it even.
3x-15=30
+15=+15=
3x=45
Finally, you would divide 3 into both sides, cancelling out the three and fiving you,
x=15

Answer:
The roots of the polynomial are;
3 + 2i
and 3-2i
Step-by-step explanation:
Here, we want to solve the given polynomial using the completing the square method
We start by dividing through by 8
This will give;
x^2 - 6x = -13
To complete the square, we simply divide the coefficient of x by 2 and square it
We have this as -6/2 = -3
square it;; = (-3)^2 = 9
Add it to both sides
x^2 - 6x + 9 = -13 + 9
x^2 - 6x + 9 = -4
(x-3)^2 = -4
Find the square root of both sides
x-3 = ±2i
x = 3 + 2i
or x = 3-2i
Well the line is called a ray because because the left of the endpoint is a dot and it doesn't go anywhere. So your answer is a ray.
