Answer:

l = 2.25 cm

Step-by-step explanation:

given l is inversely proportional to w² then the equation relating them is

l = $\frac{k}{w^2}$ ← k is the constant of proportion

(i)

to find k use the condition w = 1.5 , l = 16 , then

16 = $\frac{k}{1.5^2}$ = $\frac{k}{2.25}$ ( multiply both sides by 2.25 )

36 = k

l = $\frac{36}{w^2}$ ← equation of proportion

(ii)

when w = 4 , then

l = $\frac{36}{4^2}$ = $\frac{36}{16}$ = 2.25 cm

Answer:

$\huge\boxed{x=8;\ y=1\to(8;\ 1)}$

Step-by-step explanation:

$\left\{\begin{array}{ccc}y=x-7&(1)\\5+2y=7&(2)\end{array}\right\\\\\text{Substitute (1) to (2) and solve for x:}\\\\5+2(x-7)=7\qquad\text{use the distributive property}\\\\5+(2)(x)+(2)(-7)=7\\\\5+2x-14=7\\\\2x+(5-14)=7\\\\2x-9=7\qquad\text{add 9 to both sides}\\\\2x-9+9=7+9\\\\2x=16\qquad\text{divide both sides by 2}\\\\\dfrac{2x}{2}=\dfrac{16}{2}\\\\\boxed{x=8}$

$\text{Substitute it to (1):}\\\\y=8-7\\\\\boxed{y=1}$
