Here is an equation: 4x−4=4x+__. What could you write in the blank so the equation would be true for:
No values of x
All values of x
One value of x
Answer:
here
Step-by-step explanation:
23
-4
-4x
Write 21 in the blank for no values of x, write -4 in the blank for all the values of x and write -4x in the blank for one value of x.
Given-
Equation given in the problem is,
[tex]4x-4=4x+[/tex]___
In the given equation there is one variable [tex]x[/tex] which is unknown.
Put 21 in the blank to make equation true for the no values of x, we get,[tex]4x-4=4x+23[/tex]
[tex]4x-4x=21+4[/tex]
[tex]0=25[/tex]
It will work for no value of x.
Put -4 in the blank to make equation true for the no values of x, we get,
[tex]4x-4=4x+(-4)[/tex]
It will work for any odd value of [tex]x[/tex].
Put -4x in the blank to make equation true for the one values of x, we get,[tex]4x-4=4x-4x[/tex]
[tex]4x-4=0[/tex]
[tex]x=1[/tex]
Here we get one single solution.
Hence Write 21 in the blank for no values of x, write -4 for all the values of x and write -4x in the blank for one value of x.

[tex]y[/tex] will not be [tex]\text {zero}[/tex] in all three cases.
Step-by-step explanation:
Given information:
From, an ordered pair [tex](0,y)[/tex]
If, [tex]y[/tex] becomes zero then the point will shift to origin hence
[tex]y[/tex] will not be zero.
Now , in the second case the [tex]y[/tex] will not be zero from the graph.
Now, As we are given the equation of a line
[tex]y=mx+b[/tex]
As, the line is not drawn from the origin hence it can not have the point (0,0)
Hence,also in this case [tex]y[/tex] can not be zero.

Which type of reaction is NaCl + AgNO3 → NaNO3 + AgCl?
A. synthesis
B. decomposition
C. oxidation
D. replacement
Step-by-step explanation:
The reaction NaCL + AgNO3 → NaNO3 + AgCL is a replacement reaction.
The given chemical reaction NaCl + AgNO3 → NaNO3 + AgCl is a replacement reaction. Option D is correct.
When elements swap positions in compounds, a replacement reaction takes place. Ions are involved in this kind of response. In most cases, more reactive elements take the place of less reactive ones. When one element replaces another in a compound, it is known as a single replacement reaction.
Here,
In the given chemical reaction, Na is replaced by Ag, As per the above definition of the replacement reaction.
NaCl + AgNO3 = Na- cl + Ag-NO3 → NaNO3 + AgCl
Thus, the given chemical reaction NaCl + AgNO3 → NaNO3 + AgCl is a replacement reaction. Option D is correct.

For Emily’s birthday, her father treated her and five friends to a dinner at a restaurant at the mall. Emily and her friends ordered three pizza dinners at $6.25 each and three chicken baskets at $7.50 each. All six people ordered soft drinks costing $1.25 each. The sales tax on the meal was 4.5%, and the tip was 15%. What was the total cost of the meal, including the sales tax and the tip?
Answer:
$58.58
Step-by-step explanation:
the meal was $48.75
the tax was 4.5%
Multiply 48.75 by 4.5 as a decimal to do this divide 4.5 by 100 = 0.045
48.75 x 0.045 = 2.19375 round to the nearest hundreth = 2.19
48.75 + 2.19 = 50.94
tip on tax = 58.58

What is the area of the rectangle?The area of the rectangle is the product of the length and width of a given rectangle.
The area of the rectangle = length × Width
We know that the Total number of seats = Total of rows × Number of seats in each row
Let the total number of rows be y. The theater has 384 seats and each row has 16 seats then we get;
384= y × 16
y= 384/16= 24
There are 24 rows each having 16 seats making the total of 384.
Area= length × width
Area 1= 320= 16 × 20
Area 2 = 64

64 = 16 x
