Answer:
D. y = 2x -3
Step-by-step explanation:
The equation of a line in slope-intercept form is
y = mx + b
We need to find m, the slope, and b, the y-intercept.
We can find those two numbers from the graph.
We look in the graph and see that the y-intercept, b, is -3.
Now we have y = mx - 3.
Now we look for the slope. Start at (0, -2). We need to go vertically and horizontally to the next point that is easy to read. We see that point (1, -1) is on a grid intersection making it easy to read, so we will use that point.
Go up 2 units. That is a rise of positive 2. Now go right 1 unit. That is a run of positive 1.
slope = rise/run = 2/1 = 2
m = 2, so now we have
y = 2x - 3
Answer: D. y = 2x -3
Answer: D. 2550 cm³
<u>Step-by-step explanation:</u>
Volume of one box = Length x width x height
Volume of 6 boxes = 6(L x w x h)
= 6(14 x 6 x 5)
= 6(14 x 30)
= 6(420)
= 2520
You are not going to be able to find a numerical value of this triangle because you do not know the type of triangle or the other side length. You can represent the perimeter using algebra though.
To find the perimeter you add the lengths of all 3 sides.
To show this as an algebraic expression, you would put 1 dm + 3 dm + x.
This will simplify to x + 4 dm, where x is the length of the missing side (in decimeter).
