For this case we have that by definition, the slope of a line is given by:

m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}

Two points are needed through which the line passes:

(x_ {1}, y_ {1}): (- 1.75; 14.5)\\(x_ {2}, y_ {2}}: (- 1; 4.4)

Substituting:m = \frac {4.4-14.5} {- 1 - (- 1.75)}\\m = \frac {-10.1} {0.75}\\m = -13.46666666

Rounding:

m = -13.47

Answer:

m = -13.47

Points P and Q belong to segment AB . If AB = a, AP = 2PQ = 2QB, find the distance: between the midpoints of segments AP and QB
amid [387]

Answer:

\frac{a}{8}

Step-by-step explanation:

AB = a

AP = 2PQ = 2QB

AB = AP + PQ + QB

     = AP + \frac{AP}{2} + \frac{AP}{2}

AB = 2AP

AP = \frac{a}{2} -----(1)

And we know QB = \frac{AP}{2}

QB= AP/2 = \frac{a}{4} ---------(2)

Now midpoint of AP = \frac{a}{2} × \frac{1}{2} = \frac{a}{4}

and midpoint of QB = \frac{a}{4} × \frac{1}{2} = \frac{a}{8}

distance between these midpoints = \frac{a}{4} - \frac{a}{8}

= \frac{a}{8}

The Coffee Counter charges ​$8 per pound for Kenyan French Roast coffee and ​$7 per pound for Sumatran coffee.
spayn [35]

Answer:

Kenyan French Roast coffee x=6

Sumatran coffee y=14

Step-by-step explanation:

x+y=20     blend coffee

8x+7y=7.3(20)     selling price

x+y=20 ⇒ x=20-y

substitute in the equation:

8x+7y=7.3(20)

8(20-y)+7y=7.3(20) for 20 pound blend

160-8y+7y=146

-y=146-160

y=14 pond

x+y=20

x=20-14=6

check : 14*7+6(8)=146/7.3=20 pound
