I’ll say it is a large difference
Answer:
Hey there!
1 person can fix 1/3 of the road in 5 hours.
1 person can fix 1/15 of the road in 1 hour.
4 people can fix the road in 15/4, or 3.75 hours.
This is equal to 225 minutes.
Let me know if this helps :)
X^2+16-38=0
find what 2 numbers multiply to get -38 and add to get 16
find factors of 38
2 times 19
there is no way to use common factor so use quadratic formula which is
x=
or x=
ax^2+bx+c=0 subsitte
a=1
b=16
c=-38
subsitute
=
=
=
=
so the answers for x are
and
which are aprox -2.099504938362 and +18.099504938362
so it would be
(x-[-8+√102])(x+[8+√102])=0
Answer:
(1,4),(2,12)
----------
The form is y = ab^x
12 = ab^2
4 = ab^1
------------
Divide the 1st by the 2nd to get:
3 = b
--------
Substitute that into the 2nd equation to solve for "a":
4 = a*3^1
a=(4/3)
-------------
EQUATION:
y = (4/3)*2^x
