The domain is the scope of the x values. In this case (-2,-1) is a hole, so x>-2 is one end of the domain, while (3,3) is defined. So the domain using interval notation is (-2,3] which can also be expressed -2 < x ≤ 3, answer option 1
The value of 7 in 26,475 is ten times greater than the value of 7 in 503,497.
This is because the first 7 is in the tens place and the second seven is in the ones place. Everytime you move to the next "place" you are basically making the number ten times smaller or greater.

1 gallon = 128 oz
2 gallons = 256 oz
256/10 = 25.6 oz
each person received 25.6 oz of punch or 3.2 cups
Let
x---------> <span> josh"age
y--------> </span><span>autumn' age
we know that
x+y=88--------> y=88-x---------> equation 1
(x-9)=4*(y-9)--------> equation 2
substitute equation 1 in equation 2
(x-9)=4*(88-x-9)
x-9=4*(79-x)
x-9=316-4x
x+4x=316+9
5x=325
x=65
the answer is
</span>josh"age is 65 years
