X+2y=18
-x -x
2y=-x+18
/2 /2 /2

y=mx+b
y=-1/2x+9

the slope is -1/2

You solve for y. you dont need the x intercept
x+2y=18
2y=-x+18
divide everything by two
y=-1/2x+9
the slope would be -1/2
since in the equation y=mx+b
m represents the slope which in this case would be -1/2

What should be the paper weight

nata0808 [166]

Answer:

6.25 cm

Step-by-step explanation:

$\rho=\dfrac{m}{V} \\\\V_{\text{pyramid}}= A_{\text{base}}\cdot h \cdot \dfrac{1}{3} \\\\1.6=\dfrac{400}{V} \\\\V=120 \cdot h \cdot \dfrac{1}{3} \\\\1.6=\dfrac{400}{40h} \\\\1.6=\dfrac{10}{h} \\\\1.6h=10 \\\\h=\dfrac{10}{1.6}=6.25\text{ cm}$

Hope this helps!
