Don't understand this either
A. The data in the table represent a function. y=x/2. This is seen as for every value of x in the table, y=x/2(half of it). You can show this further by trying this fact on each value.
B. For the original function, when x =8, y=x/2=4
For the function given in this part, when x=8, y=3(8)-10
y=24-10 y=14
This means the relation given in this part has a greater value when x=8
C. When x=80, f(x)=3(80)-10
=240-10
=230
Answer:
18 units in all
Step-by-step explanation:
one side is 5 then 2 and another 2 then 3 and another 3 then a third 3 so 5+2+2+3+3+3=18
Answer:
<em>3. x = 8</em>
<em>4. lines r and s</em>
Step-by-step explanation:
3.
The angles shown are same side interior angles, so they are supplementary. Their measures add to 180 deg.
5x + 10 + 130 = 180
5x + 140 = 180
5x = 40
x = 8
4.
Lines r and s are cut by a transversal, line l. Angles 3 and 6 are alternate interior angles. Lines r and s are parallel.
