A Notebook cost $5.50 plus sales tax after sale tax the notebook is $5.83 what is the sale tax rate?
$5.83-$5.50
=$0.33 tax rate charged
Answer:
6%
Step-by-step explanation:
5.83 - 5.50 = .33 sales tax
Sales price x sales tax rate - sales tax
5.50 x sales tax rate = .33
sales tax rate = .33/5.50
sales tax rate = .06 or 6%

Which statement about f(x) = 2x2 – 3x - 5 is true?
A The zeros are - and -1, because f(x) = (x + 1)(2x + 5).
2
5
B The zeros are - and 1, because f(x) = (x - 1)(2x + 5).
2
C The zeros are -1 and, because f(x) = (x + 1)(2x-5).
The zeros are 1 and, because f(x) = (x - 1)(2x - 5).

Answer:
C. The zeros are -1 and 5/2, because f(x) = (x + 1)(2x-5).
Step-by-step explanation:
The zeros of the function are the values that make the factors zero. The factors need to multiply out to give the original standard-form equation.
The sign of the constant (-5) tells you the product of the constants in the factors must be -5. That is only true for choices B and C.
Additionally, the x-term needs to match the result of multiplying out the factors.
B. (x -1)(2x +5) = 2x^2 +3x -5 . . . . . . . . . wrong x-term (not -3x)
C. (x +1)(2x -5) = 2x^2 -3x -5 . . . . . . . . . matches the given f(x)
The factors of C are zero when x=-1, x=5/2.

Explanation:
A linear system of two equations in two variables will be a dependent system. This means both equations reduce to the same equation. The equations will be different only until they are reduced to the same form.
Here is one possible set of equations. The first is in slope-intercept form. The second is in point-slope form.
y = 3x +1y -7 = 3(x -2)If we subtract the first equation from the second, we get ...
(y -7) -(y) = (3(x -2)) -(3x +1)
-7 = 3x -6 -3x -1 . . . . . eliminates y
-7 = -7 . . . . . . . . . true for all values of x

what is the measure of Y
Answer:
62
Step-by-step explanation:
60 + 58 + y = 180
118 + y = 180
y = 180 - 118
y = 62
The product of six and the sum of a number x and nine equals two times x subtracted from four.
Answer:
[tex]x=-15.5[/tex]
Step-by-step explanation:
Write down what the problem is saying;
[tex]6(x+9)=2(x-4)[/tex]
Distribute;
[tex]6(x+9)=2(x-4)\\\\(6)(x)+(9)(6)=(2)(x)+(2)(-4)\\[/tex]
Simplify,
[tex]6x + 54 = 2x - 8[/tex]
Inverse operations,
[tex]6x + 54 = 2x - 8\\-2x\\\\4x + 54 = -8\\-54\\\\4x = - 62\\/4\\\\x =-15.5[/tex]

The measure of ZB is (3x – 4) and the measure of
ZD is (2x - 6)". What are the measures of angles B
and D?
mZB=
mZD =
The measure of <B and <D are 110 degrees and 70 degrees
What is Circle geometry?The sum of the opposite angle of the quadrilateral within the circle is 360 degrees.
Given the following parameters
<B = 3x - 4
<D = 2x - 6
Equate both equations
<B + <D = 180
3x - 4 + 2x - 6 = 180
5x - 10 = 180
5x = 190
x = 190/5
x = 38
Determine the measure of <B and <D
<B = 3x - 4 = 3(38) - 4
<B = 110 degrees
<D = 2x - 6
<D = 2(38) - 6
<D = 76 - 6
<D = 70 degrees
Hence the measure of <B and <D are 110 degrees and 70 degrees

On a certain hot summer day, 673 people used the public swimming pool. The daily prices are 1.75 for children and 2.00 for adults.The receipts for admission totaled to $1249.50. How many children and how many adults swam at the public pool that day?
Answer:
120 children and 388 adults bought tickets for the swimming pool
Explanation:
Create two simultanous equations:
Let c stand for the number of children that bought a ticket, and a stand for the number of adults that bought a ticket, you get your first equation, being
c
+
a
=
508
then, you now create a second equation for the prices of the tickets.
(price of childrens tickets)(number of children that swam)+(price of adults tickets)(number of adults that swam) = total money collected
so:
1.75
c
+
2.25
a
=
1083.00
now we still know, that
a
=
508
−
c
so we can substitute it into the second formula
1.75
c
+
2.25
(
508
−
c
)
=
1083
now its just simple algebra
1.75
c
+
1143
−
2.25
c
=
1083
60
=
0.5
c
so:
c
=
120
now we know, that 120 children went to the swimming pool.
and we still have the formula from before:
a
=
508
−
c
so
a
=
388
