Answer:
x<=5
Step-by-step explanation:
Two things
- direction its pointing is always how the sign will look like
- if the circle is shaded it will have an "or equals to" sign; if its blank, there is only the "greater/lesser" sign
The formula is y=mx+b
To get the slope or m, use this formula
(the second y minus the first y)/(the second x minus the first x)
Now set it up.
(10-7)/(2--1)
3/3=slope is 1.
y=1x+b
Insert one of the points for x and y.
i will do (-1,7)
7=1(-1)+b
7=-1+b
8=b
Insert this into the final equation:
y=1x+8
Try it out. If you're not sure, try both points. If it works, then you set it up correctly.
When the number of hours increases, the number of miles increases
Just expand each number after the decimal. 0.300+0.030+0.004
Answer:
-8
Step-by-step explanation:
Multiplying two negatives (or squaring them) cancels the negative, therefore, (-8)^2=64
