This is a test!!!
Please help!!!!!!!!!
THREE expressions equivalent to –81x+27.
Hey there!
One thing we can do to get an equivalent expression is to divide both sides by 3. That would get us [tex]\frac{-81x+27}{3}[/tex]. If we simplify this, we get [tex]-27x+9[/tex].
Another thing we can do is divide both sides by 27, because it is divisible by 27. That would get us [tex]\frac{-81x+27}{21}[/tex]. If we simplify this, we get [tex]-3x+1[/tex].
One last thing we can do is multiply it by 1, and add zero, because that does not change it at all. That would give us [tex]1(-81x+27)+0[/tex].
Have a terrificly amazing day! :D
1.
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.

Scientific notation of 141700000
Answer:
1.47 * 10^8Step-by-step explanation:
Given the value 141700000, we are to express in scientific notation
The standard form is expressed as A * 10^n
A is any integer between 1 and 10
n is also any integer
141700000.= 1.47 * 10^8
Note that the decimal point was shifted back 8 times, main reason the power is 8

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
37-(3×(5+2)-4)

PLEASE ANSWER COMPLETE QUESTION. WILL MARK BRAINLIEST FOR BEST ANSWER. QUESTION IS ATTACHED.
9514 1404 393
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
There are an infinite number of solutions.

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%
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]
