Answer:
x²=5-x
x²+x-5=0
1x²+1x²-5=0
[ax²+bx²+c=0]
∆=b²-4ac
∆=1²-4(-5)(1)=1+20=21
x=(-b±√∆)/2a
x=(-1±√21)/2
meaning:
x=(-1+√21)/2 or x=(-1-√21)/2
It’s more likely to be C or D
Answer:The vertex in the graph is (-2,1) and It has a maximum value of 1 ,occurs at x=-2
Step-by-step explanation:
To find the vertex of a quadratic equation you gotta find the find middle point of the equation it could be lowest or his point in the quadratic equation
In this graph the vertex is the highest point in this graph (-2,1)
The quadratic equation is a maximum because the vertex is the highest point in the graph and if the vertex point was the lowest point it would been minimum.
Answer:
For any mathematical expression follow the BODMAS rule which states that we should calculate the Brackets first (2 + 4 = 6), then the Orders (52 = 25), then any Division or Multiplication (3 x 6 (the answer to the brackets) = 18), and finally any Addition or Subtraction (18 + 25 = 43).
Step-by-step explanation:
(5+4) × 5 + 3.3
Bracket open = 9
Since there is no division, so multiply 9×5, which is 45
Then add, 45+3.3
Answer= 48.3
It says describe the perimeter with your own words, so what perimeter?
