Answer:
or
Step-by-step explanation:
Note that .
Also, note that .
So, the inequality is really equal to .
We can then add to both sides to get .
So, the solution is , or in interval notation,
4/10 and 6/10
(40% and 60%)
Answer:
two and a half
Step-by-step explanation:
Answer:
They have the same slope
Step-by-step explanation:
The standard equation of a line in point-slope form is expressed as;
y-y0 = m(x-x0)
We can see that both equations given are written in this form with a slope of 1.2. For two lines to be equal, they must have the same slope no matter the point on the lines. Hence the two equations are equal since they have different slopes.
No, Perry is not using the correct ratio, because 15:17 is not equivalent to 5:7
15 divided by 3 is indeed 5 but divided 17 by 3 does not give you 7, nor a whole number.
I hope this helps.
