If the domain of the square root function f(x) is x

<span>This question, in my opinion, is not well stated. If f(x) = √x, as the question statement seems to say, then the domain is not x<7. Rather, the domain is x≥0. If f(x) is not the square root function, but say f(x) = √(7-x) then the domain is x≤7, and for this function then the appropriate answer is d), since the x-term inside the radical has a negative coefficient.</span>

A survey of a random sample of voters shows that 29% plan to vote for Martin and 71% plan to vote for
Iteru [2.4K]

Range=±7%

Martin=71%, Lang=29%

Range for Martin=71%±7%

So, highest %=71%+7%=78%

Lowest %=71%-7%=64%

Therefore,range for Martin is between 64%-78% which is 14%

Paralell to y=4x-6 through (12,10)
stiks02 [169]

<u>ANSWER</u>

The line that is parallel to y=4x-6 through (12,10) is  y=2x-14.



<u>EXPLANATION</u>


The equation that is parallel to the line y=4x-6 has a slope that is equal to the slope of this line.

By comparing this equation to the general slope intercept form,

y=mx+c,this line has slope m=2.


Hence the line parallel to this line also has slope m=2.

Let y=mx+b be the equation of the line parallel to the line

y=4x-6

We can substitute m=2 to obtain;

y=2x+b


If the line passes through the point (12,10),then this point must satisfy its equation.


We substitute x=12 and y=10 to obtain;


10=2(12)+b


We this equation for b.


\Rightarrow 10=24+b


\Rightarrow 10-24=b


\Rightarrow -14=b


We substitute this value of  b=-14 in to y=2x+b to get;


y=2x+-14.


Hence the equation of the line that is parallel to y=4x-6 through (12,10) is  y=2x-14.

What is f(4.5) what si the value of x for which f(x)=3?
notsponge [240]
It kind of looks like your missing something in you problem.  But if f(x) = 3 is correct, then it doesn't matter what x is the answer is always going to be 3.  So f(4.5) = 3.  Most of the time though f(x) means a function of x, so there is an x in the problem.  For example: f(x) = 3x, then f(4.5) = 3*4.5 = 13.5.
