total points
each person scores $6$ points,
you can see all the multiples of 6 to see if you get 42
or you can just divide 42 by 6, to get the number of people.
$\frac{42}6=7$
Answer:
891,962,172,409
Step-by-step explanation:
that is standard form
Answer:
B
Step-by-step explanation:
y = f(x) + c is the graph y = f(x) shifted upward c units.
y = f(x) - c is the graph of y = f(x) shifted downward c units.
y = f(x - c) is the graph of y = f(x) shifted to the right c units.
y = f(x + c ) is the graph of y = f(x) shifted to the left c units.
1) x^2=64 is the same as x=the root of 64 which gives us: (+-)8
2) here you must us pq-formel as:
5m^2-5m=60
5m^2-5m-60=0
(m^2-5m-60)/5=0
m^2-m-12=0
m=0,5(+-) the root of 0,25+12
m=0,5(+-)3,5
m1=0,5+3,5
m2=0,5-3,5
15) x^2=7x
x^2-7x=0 here there is two x, so:
x(x-7)=0
x1=0
x2=7

Here you can only use PQ formula in all the others, just as I did in the question number 2</span>
