Answer:


First we calculate the slope (which is called "m".


Slope = m = (Y2 -Y1) ÷ (X2 -X1)


m = (-8 -1) / (5 -2) = -9 / 3 = -3


We next fill in this equation: b = y -mx


We know m = -3 and we can choose a point (2, 1) to calculate "b"


b = 1 --3 * 2 b = 7


Putting this into y = mx +b


y = -3x +7

On a average day a horse might drink 50 la sheep might drink 4 l and a chicken might drink 200ml how much water would a farm wit
horsena [70]
Horse- 50l
sheep-4l
chicken-200ml

first you have to convert all the symbols into one, so we'll convert liters into milliliters,
 
1000ml=1l

horse= 50 ×1000=50000ml
sheep=4×1000=4000ml
chicken= 200ml

so now we have to multiply them by the number of animals,

h=50000ml×3=150000ml
s=4000×15=60000ml
c=200×12=2400ml

now add them together,

150000+60000+2400=212400ml

convert it into litres, 
212400÷1000=212.4l

answer= 212.4 l

Please help me 50 points.

First we have to convert 60 feet to inches.  since there are 12 inches in a foot we will multiply by 12
60×12=720
since the real thing is 720 inches and the scale drawing is 15 inches we can make a ratio
720:15
then simpliy
48:1
would be your answer.  It means that for every 48 inches it is in real life the scale drawing will be one inch

London was offered a job that paid a salary of \$93,000$93,000 in its first year. The salary was set to increase by 2% per year
Tema [17]

Answer: Amount = $143776

Step-by-step explanation:

Given that London was offered a job that paid a salary of $93,000 in its first year. The salary was set to increase by 2% per year every year.

Let P = 93000

Rate R = 2%

The amount of salary he will receive after 22 years can be calculated by using exponential equation

A = P(1 + 2%)^t

Where t = 22 years

A = 93000(1.02)^22

A = 93000 × 1.545979

A = 143776.11 dollars
