Step-by-step explanation:
the two ends , made up of triangles make an 8x5x5 box1
box1 = 200
the center piece makes a box2 of 10x8x5
box2 = 400
volume = 600

Step-by-step explanation:
Hi there!
<u>What we need to know:</u>
- Slope-intercept form:
where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)
- Parallel lines have the same slope (m) and different y-intercepts (b)
<u>1) Determine the slope (m)</u>
Rearrange this equation in slope-intercept form (so it's easier for us to identify the slope)
Subtract 6x from both sides to isolate 2y
Divide both sides by 2 to isolate y
Now, we can tell clearly that -3 is in the place of m. Therefore, because parallel lines have the same slope, we know that the line we're solving for will also have a slope of -3. Plug this into :
<u>2) Determine the y-intercept</u>
Plug in the given point (-1,7)
Subtract 3 from both sides
Therefore, the y-intercept of the line is 4. Plug this back into :
I hope this helps!
