Answer:
parellel
Step-by-step explanation:
You can write out the equation like so: t = 2(d) and the dvd costs d. So, d + 2d = 1296. Which is also 3D=1296. So divide 1296/3 to solve for the cost of the DVD player = 432 and the cost of the tv is 2(d) or 2 x 432 = 864.
all three angles are the same
so it could be n squared or 3n+18
Answer: Check out the graph below
The graph is a straight line through the points (0,6) and (1,8)
====================================
Explanation:
Plug in x = 0 to find that...
y = 2x+6
y = 2(0)+6
y = 0 + 6
y = 6
The point (0,6) is on the line
---------
Repeat for x = 1
y = 2x+6
y = 2(1)+6
y = 2 + 6
y = 8
The point (1,8) is also on the line
---------
Now plot the two points together on the same xy grid.
Draw a straight line through the two points. Stretch the line as far as you can in either direction. See below. I used GeoGebra to make the graph. It's a free graphing app.
Desmos is another useful free graphing tool. There are many options if you don't have a graphing calculator.
The 4th box is the answer because 1/3 + 1/5 doesn't equal 2/8
