if a regular polygon has exterior angle that measure 36 each how manys sides does the polygon have
your answer is: 10
Answer:
Points -2 and -6 on the number line are the two solutions.
Step-by-step explanation:
Use the definition of absolute value as a starting point
To solve the equation, you need to treat the two cases as above:
The solution x=-2 is consistent with the condition x>=-4, so it is the first and valid solution. Now the second case of the absolute value:
Again, the second solution -6 complies with the requirement that x<-4, so it is valid.
Answer:
-6 ;
ax² + bx + c ;
-1
Step-by-step explanation:
1)
Give thequadratic equation :
4x² - 6x - 5
The values of a, b, c are the Coefficient of x², x and the constant respectively
Therefore, the value of b is the Coefficient of x = - 6
2.)
Standard form of a quadratic equation is :
ax² + bx + c
a = Coefficient of x² ; b = Coefficient of x ; c is a constant
3.)
2x² - 4x + 7
Axis of symmetry :
-b / 2a
a = 2 ; b = - 4, c = 7
-b / 2a = - 4 / 2(2)
= - 4 / 4
= - 1
It is 7 4/5 because 4 3/5 + 3 1/5 = 7 4/5
