D + 5 >= 17
We can subtract 5 from each side:
d >= 12
To get 20 on the right, we have to add 8 to each side (20-12=8).
d + 8 >= 20
To get d - 5 from the first expression (d + 5 >= 17) we have to subtract ten from each side (5-10=-5) and we get:
d - 5 >= 7
What's the actual problem?
The equation is 30,000+200x=80,000. X is the number of sales.
Answer:
y=(-6/5)x+8.6
Step-by-step explanation:
If a line is perpendicular to 5x-6y=9, then it must have a slope that is the negative reciprocal.
1) Fine the slope of the first line by setting the equation equal to y.
5x-6y=9
5x-9= 6y
(5/6)x-1.5=y
slope= 5/6
2) Find the negative reciprocal of the slope
slope: 5/6
reciprocal: 6/5
negative reciprocal: -6/5
3) We now get to use the points (-3, 5) by plugging them into slope-intercept form. The goal is finding the y-intercept.
y=mx+b
5=(-6/5)(-3)+b
5=(-18/5)+b
5= -3.6+b
b= 8.6
4) Now we put everything back in slope-intercept form.
y=(-6/5)x+8.6
It has a fixed method in regards o finding the <span>fraction for 0.27 repeating. Let us now write down the method for you to understand clearly
Let us assume that
x = 0.27272727.....
Now let us multiply both sides by 100 to get a second equation
100x = 27.272727......
Let us now subtract the first equation from the second. We get
100x = 27.272727......
x = 0.27272727....
We get
99x = 27
x = 27/99
= 3/11
From the above deduction, we can conclude that </span><span>the fraction for 0.27 repeating is 3/11. </span>
