Answer:

-18

Step-by-step explanation:

We can find the slope of a line using two points by

m = (y2-y1)/(x2-x1)

   = (-15-3)/(17-16)

   = -18/1

-18

Answer:

m= -18.

Step-by-step explanation:

To find the slope of the line, we will need to use the slope formula :

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

Plug in the points, giving us:

m=  \frac{-15-3  }{17-16 }

Simplifying this results in:

m= \frac{-18}{1}

m= -18

Therefore, the slope of the line is -18.

tino4ka555 [31]

Answer: $ 3,360

Step-by-step explanation:

Given : The principal amount borrowed for loan : P=\ \$14,000

Time period : t=4

Rate of interest : r=6\%=0.06

The formula to calculate the simple interest is given by :-

S.I.=P\times r\times t\\\\\Rightatrrow\ S.I.=14000\times4\times0.06\\\\\Rightatrrow\ S.I.=3360

Hence, the interest due on the loan = $ 3,360

alan is spreading fertilizer on a field to get it ready for planting. The directions say to use 4/5 of a quart of fertilizer for
Ostrovityanka [42]

Answer:

48.6 quart of fertilizer

Step-by-step explanation:

The directions say to use 4/5 of a quart of fertilizer for each acre of land.

Alan has two fields,

Field 1

22 1/2 acre of land

1 acre of land = 4/5 quart

22 1/2 acre of land = x

Cross Multiply

x = 22 1/2 × 4/5

x = 45/2 × 4/5

x = 18 quart of fertilizer

Field 2

38 1/4 acres of land

1 acre of land = 4/5 quart

38 1/4 acre of land = x

Cross Multiply

x = 38 1/4 × 4/5

x = 153/4 × 4/5

x = 30.6 quart of fertilizer

The total fertilizer that Alan will need for his two fields is calculated as:

18 quart of fertilizer + 30.6 quart of fertilizer

= 48.6 quart of fertilizer
