Answer:

Step-by-step explanation:
Using the slope formula, you can form this equation! The slope of any equation would replace the m, and the y intercept would replace b!
I added in the slope formula at the bottom, just in case, so you'll see what I mean!
I hope this helps, and I explained enough! Have a great day c:
Answer:
It's A, c =2.5d
Step-by-step explanation:
When it comes to problems like this, I usually look through the answers and try to plug in the numbers until I get the right equation that fits with the graph.
2.5(5) = 12.5
2.5(10)= 25
2.5(15)= 37.5
2.5(20) = 50
2.5(25) = 62.5
If you compare this to the graph, you'll notice the solutions are the same as the Total Cost (c). That's because c= 2.5d is the right equation for this graph. (Sorry if my explanation is confusing)
Answer:
400 mm
Step-by-step explanation:
8 * 10 = 80
80 * 5 = 400
400 mm
The answer to number eight is
That it would have to reflect in the middle and it has Proportional angles.
Answer:
x = 10
Step-by-step explanation:
22 - 2x + 4(x - 2) = 34
22 - 2x + 4x - 8 = 34
22 - 8 - 2x + 4x = 34
14 + 2x = 34
-14 -14
--------------------------------
2x = 20
/2 /2
--------------------------------
x = 10
