Answer:
x = -11
Step-by-step explanation:
To find the zero of this function, factor the equation:
g(x) =
g(x) = (x + 11) (x + 11)
g(x) =
The zeros of a function are the values of x that will make g(x) equal 0. So, the zero of this function is -11, because -11 + 11 = 0. So, x = -11.
Answer:
Number of boys = 675
Step-by-step explanation:
Given that:
There are 5 times as many boys as girls in a school.
Number of pupils in school = 810
Let,
x be the number of girls
y be the number of boys
According to given statement;
x+y=810 Eqn 1
y = 5x Eqn 2
Putting y=5x in the Eqn 1
x+5x=810
6x=810
Dividing both sides by 6
Putting x=135 in Eqn 2
y = 5(135)
y = 675
Hence,
Number of boys = 675
