Maria would like to leave a tip (t) of at least 15% of her dinner bill (b). Which inequality best could be used to find the amou

mr_godi [17]

First let's define the variables of the problem:
t: Tip
b: dinner bill.
We write the inequality based on the following proposition:
"Maria would like to leave a tip (t) of at least 15% of her dinner bill (b)"
We have then that the inequation is:
t> = 0.15b
Answer:
An inequality best could be used to find the amount of the tip Maria would like to leave is:
t> = 0.15b

Your friend claims that if a line has a slope less than 1, then any line perpendicular to it must have a positive slope. Is your

mezya [45]

Answer:

The friend's claim is not correct

Step-by-step explanation:

we know that

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal yo -1)

Example

A given line has a slope of $m_1=1/2$ ---> (is less than 1)

the slope of the line perpendicular to the given line is equal to

$m_1*m_2=-1$

substitute

$(1/2)*m_2=-1$

$m_2=-2$

the perpendicular line don't have a positive slope

therefore

The friend's claim is not correct

Can someone please clearly and correctly work out Q19? Would appreciate it a lot! :)

$x^{2} +10x+30$
I always start by moving the last term to the other side
$x^{2} +10x=-30$
To complete the square you take term 'b' , divide it by 2 then square it
$( \frac{10}{2} )^2$ = 25
We have to add 25 to what we have and what you do to one side you have to do to the other
$x^{2} +10x+25=-30+25$
$x^{2} +10x+25=-5$
Now we factor what is on the left side of the equation
$(x+5)^2=-5$
The last step is to move our right side of the equation back over
$(x+5)^2+5$ - which is your answer :)))
