F(-3) means x = -3
Look at the functions above, if x <= - 3 then use F(x) = 7 - x
so
F(-3) = 7 - x, replace x = - 3 into the function
F(-3) = 7 - (-3)
F(-3) = 7 + 3
F(-3) = 10
The symbol to show that there are parallel lines is normally just a set
of vertical lines. Although if these are being drawn on a page and need
to be labelled as part of a shape or diagram, sometimes arrows will be
used to show they are parallel - either one arrow in the middle of the
line, or two arrows to show they are parallel but in different
directions.
Answer:
Jason has 75 pencils.
Step-by-step explanation:
In order to get from 4 to 100, you must multiply by 25 (100/4 = 25). And in order to find the amount of pencils Jason has, you must have an equivalent ratio. So you have to also multiply 3 by 25, 3 * 25 = 75. Jason has 75 pencils.
