I would answer this question if I had a picture or something to guide me
If you solve the equation to get the equation y=mx+b then 2x+5y=10 equals to
y=(-2x-10)/5 . If you use a graphing calculator and type that into y= it should graph it for you going through coordinates (-3,4) , (0,-2) , (3,-8) and so forth
Answer:
1 is Answer.
Step-by-step explanation
= 
As we know that ω²+ω+1=0
Thus putting in above equation, we get
= 
Rearranging and simplifying:
= 
=
= 
= 1 Answer
1) 13a=-5
Make a the subject of the formula by dividing both sides by 13(the coefficient of a)
13a/13=-5/13
Therefore a= -0.385
The second one). 12-b= 12.5
You take the 12 to the other side making b subject of the formula (-b in this case)
-b= 12.5-12
-b= 0.5
(You cannot leave b with a negative sign so you will divide both sides by -1 to cancel out the negative sign)
-b/-1= 0.5/-1
Therefore b=-0.5
The third one). -0.1= -10c
You will divide both sides by the coefficient of c(number next to c) which is -10
-0.1/-10= -10c/-10
Hence, c= 0.01
Answer:
e
Step-by-step explanation:
<u><em>I think your full question is below: </em></u>
<em>A store asked 250 of its customers whether they were satisfied with the service or not. The responses were also classified according to the gender of the customers. We want to study whether there is a relationship between satisfaction and gender.
</em>
<em>A meaningful display of the data from this study would be:
</em>
<em>(a) side-by-side boxplots
</em>
<em>(b) a pie chart
</em>
<em>(c) a histogram
</em>
<em>(d) a scatterplot
</em>
<em>(e) a two-way table</em>
Explain: two-way frequency table will deal with two variables, between two sets of categorical data. With genders we have two types: man and female, so two - way table are the best option to display your data.
