Answer: -3 2/5
Step-by-step explanation:
When both integers are negative, you can treat them the same as positive numbers and add a negative sign to your final sum.
1+2 2/5 (or 2 4/10 or 2.4) is equal to 3 2/5. So (-1)+ (-2 2/5) is equal to -3 2/5, or -3.4.
Answer:
C) x=2 y=-1 z=3
Step-by-step explanation:
2x + y - z = 0
2(2) + (-1) - (3) = 0
0 = 0
x - y + z =6
2 - (-1) + 3 = 6
6 = 6
x + 2y + z = 3
2 + 2(-1) + 3 = 3
3 = 3
Answer:
Vertex (5 ,-9)
Step-by-step explanation:
Given : Function f(x) = (x – 8)(x – 2).
To find : What is the vertex of the quadratic function .
Solution : We have given that f(x) = (x – 8)(x – 2).
On removing parenthesis
f(x) = x²-2x -8x +16.
f(x) = x²-10x +16.
We need to find vertex of this function ,
Vertex: (h, k)
h = -
.
Plugging values
h = -
.
h = 5 this is the x- coordinate,
Now , we will plug x= 5 in quadratic function .
k = (5)²-10(5)+16.
k = 25-50 + 16
k= -9.
Vertex (5 ,-9)
Therefore, Vertex (5 ,-9).
