total bill before any discounts $13.
she is a student, so she gets 20% off.
she brought an item of clothing, so she gets 5% off.
so she's really getting 20% + 5% off, namely 25% off her bill.
Subtract 350 from both sides then divide both sides by 25.
(c-350)/25 = h
Sorry can't include the graphs, just subsitute y for f(x) and graph by subsituting values
so domain is the set of numbers you are allowed to use
range is the set of number you get from inputing the numbers from the domain into the function
so normally the domain is all real numbers
you must exclude number from the domain that make mathematical undifined impossible stuff exg dividing by zero so
not sure about the ranges so I will leave that out
a. denomenator is x-2
cannot be zero
x-2=0
add 2
x=2
domain: all real numbers except for 2
b. x+2=deomenator
x+2=0
subtract 2
x=-2
x acannot be -2
domain: all real numbers except for -2
c
x cannot be 0
domain: all real numbers except for 0
d. x cannot be -1
domain: all real numbers except for -1
e: x cannot be a negative number or 0
domain: all real numbers greater than zero
f: x cannnot be -2
domain: al real numbers except -2
g: x cannot be 0
domain: all real number except 0
h: x cannot be zero
domain: all real numbers except 0
i: x cannot be 1
doman: all real number except 1
j: 5x-2=0
add 2
5x=2
divide 5
x=2/5
x cannot be 2/5
domain: all real numbers except for 2/5
Answer:
1. Find < ACB
2. Use that triangles =180 to find <B = 41
Step-by-step explanation:
1.We need to find < ACB
<ACB +<DBC= 180 They make a straight line
Subtract DBC from each side
<ACB = 180 - <DBC
We know DCB = 113
ACB = 180 -113
ACB = 67
2.The three angles of a triangle = 180, so we can then find <B
<A +<B + <ACB = 180
72 + B + 67 = 180
Combine like terms
139+ <B = 180
Subtract 139 from each side
<B = 180-139
<B =41
