This is the answer for the first one
3x + 1 = y
x: 1 | 2 | 3 |
------|---|--- |----------------
y: 4 | 7 | 10|
so make points at (1,4) (2,7) and (3,10), and connect them to get the line
4x + 1
x: 1 | 2 | 3
----------------
y: 5 | 9 | 13
Make points at (1,5) (2,9) and (3,13)
IF they do not intersect yet, continue making points until they intersect. Make note of the point in which they intersect, and that is your answer
hope this helps
We know that
[volume of a prism]=length*<span>width*height
</span><span>length=1 1/4 cm-------> (1*4+1)/4-------> 5/4 cm
</span><span>width = 4 cm
height=</span><span>3 1/4 cm---------> (3*4+1)/4------> 13/4 cm
</span>[volume of a prism]=(5/4)*4*13/4-----------> 65/4--------> 16.25 cm³
the answer is
the volume is 16.25 cm³ (16 1/4 cm³)
i need more than that to answer the question bruh
