Answer: $-6$

Do Keep Change Flip (KCF)

Keep: $15/4$

Change: ÷ into ×

Flip: $-5/8$ into $8/-5$

Multiply

$15/4*8/-5=120/-20$

Divide

$120/-20=-6$

Answer:

9%

Step-by-step explanation:

Original rectangle: 100 cm by 200 cm

Original area: 100 cm * 200 cm = 20,000 cm^2

Reduced by 70%, the measures are now 30% of they they were.

30% of 100 cm = 30 cm

30% of 200 cm = 60 cm

New area: 30 cm * 60 cm = 1800 cm^3

New area equals what percent of original area?

1800/20,000 * 100 = 9%

Answer:

$\large\boxed{C.\ y=2+x^4}$

Step-by-step explanation:

The slope-intercept form of an equation of linear function:

$y=mx+b$

m - slope

b - y-intercept

============================

$A.\\\\9y+3=0\qquad\text{subtract 3 from both sides}\\\\9y=-3\qquad\text{divide both sides by 9}\\\\y=-\dfrac{3}{9}\\\\y=-\dfrac{1}{3}\to m=0,\ b=-\dfrac{1}{3}$

$B.\\\\y-4x=1\qquad\text{add}\ 4x\ \text{to both sides}\\\\y=4x+1\to m=4,\ b=1$

$C.\\\\y=2+x^4\qquad\text{nonlinear, because}\ x\ \text{is in fourth power}$

$D.\\\\x-2y=7\qquad\text{subtract}\ x\ \text{from both sides}\\\\-2y=-x+7\qquad\text{divide both sides by (-2)}\\\\y=\dfrac{1}{2}x-\dfrac{7}{2}\to m=\dfrac{1}{2},\ b=-\dfrac{7}{2}$

$E.\\\\\dfrac{x}{y}+1=2\qquad\text{subtract 1 from both sides}\\\\\dfrac{x}{y}=1\to y=x\to m=1,\ b=0$
