Answer:

IT is 41.5 heres the steps

Step-by-step explanation:

first step 21 divided by 2 = 10.5

Then you do 10.5 + 1 = 11.5  

then you do 11.5 times 5 =  57.5

Then 2 times 2 times 2 times 2= 16

then 16 - 57.5 = 41.5 is your answer

Which expression represents the phrase "twice the difference of a number and 5"?
KatRina [158]

The expression that represents the phrase "twice the difference of a number and 5" is 2(x - 5).

<h3>What is the expression that represents the phrase?</h3>

The difference of a number and 5 is given by:

x - 5.

As we don't know the number, hence we call it x.

Twice that is:

2(x - 5).

Hence the expression that represents the phrase "twice the difference of a number and 5" is 2(x - 5).

Answer: FIRST OPTION.

Step-by-step explanation:

First, it is important to remember that the Slope-Intercept form of the equation of a line is the shown below:

y=mx+b

Where "m" is the slope of the line and "b" is the y-intercept.

By definiton, given a System of Linear equations, if they are exactly the same line, then the System of equations have Infinely many solutions.

In this case you have the following System of Linear equations given in the exercise:

\left \{ {{y=-2x+5} \atop {y=ax+b}} \right.

So, since you need the system has Infinite solutions, you know that the slope and the y-intercept of both lines must be equal.

Therefore, you can identify that the value of "a" and "b" must be the following:

a=-2\\\\b=5

So the Linear System would be the shown below:

\left \{ {{y=-2x+5} \atop {y=-2x+5}} \right.
