For an equation with slope m and point (x1,y1)
the equation is
y-y1=m(x-x1)

slope=(y2-y1)/(x2-x1)
(x,y)
(7,5)
(-4,-1)

slope=(-1-5)/(-4-7)=(-6)/(-11)=6/11

point is (7,5) or (-4,-1)
equation is

y-5=(6/11)(x-7) and
y+1=(6/11)(x+4)

Which expression is equivalent to -1/4( -1/2x - 3/4) -1/2 ( 3/4x + 1/8)

solniwko [45]

Answer:

Step-by-step explanation:

$\frac{-1}{4}(\frac{-1}{2}x-\frac{3}{4})-\frac{1}{2}(\frac{3}{4}x+\frac{1}{8})\\\\=\frac{-1}{4}*\frac{-1}{2}x-\frac{-1}{4}*\frac{3}{4}-\frac{1}{2}*\frac{3}{4}x-\frac{1}{2}*\frac{1}{8}\\\\=\frac{1}{8}x+\frac{3}{16}-\frac{3}{8}x-\frac{1}{16}\\\\=\frac{1}{8}x-\frac{3}{8}x+\frac{3}{16}-\frac{1}{16}\\\\=\frac{(1-3)x}{8}+\frac{3-1}{16}\\\\=\frac{-2}{8}x+\frac{2}{16}\\\\=\frac{-1}{4}x+\frac{1}{4}$

At 12pm, the temperature was 57o F. By 5pm, the thermometer read 36o F. Assuming a constant change in temperature, calculate and

BaLLatris [955]

Answer:

Unit rate of change = -4.2°F/hour

Step-by-step explanation:

Assuming a constant rate of change, a relationship between the change of temperature as a function of time (in hours) can be described as follows:

$r= \frac{(36^oF - 57^o F)}{17 - 12}\\r= \frac{-4.2^o F}{hour}$

There is a temperature drop from 12pm to 5pm, which explains the rate of change being negative. This rate means that at every hour that goes by, the temperature drops by 4.2 degrees.
