Answer:
20
Step-by-step explanation:
because if you subtract 270 by 240 its 20
Answer:
(2, 0) and (6, 0)
Step-by-step explanation:
To get the x intersept put y = 0
So, the intersepts are
(2, 0) and (6, 0)
Answer:
Z=-3 or Z=11
Step-by-step explanation:
we know that
The distance between point Y and point Z is 7 units
The point Y is located on the number line at 4
we have two possibilities
The point Z could be located to the right of point Y
The point Z could be located to the left of point Y
so
Z is either 7 units to the left of 4 or 7 units to the right of 4
<em>First case</em>
point Z to the right of point Y
To find out the coordinate of point Z sum the distance YZ to the coordinate of point Y
so
(4+7)=11
therefore
The first possibility is
Point Z is located at 11
<em>Second case</em>
point Z to the left of point Y
To find out the coordinate of point Z subtract the distance YZ from the coordinate of point Y
so
(4-7)=-3
therefore
The second possibility is
Point Z is located at -3
therefore
Z=-3 or Z=11
