The sum of two numbers is 153. if four times the smaller number is subtracted from the larger number, the result is 18. find th

sleet_krkn [62]

X = larger number and y = smaller number

x + y = 153....x = 153 - y
x - 4y = 18

153 - y - 4y = 18
153 - 5y = 18
-5y = 18 - 153
-5y = -135
y = -135/-5
y = 27 <=== smaller number

x - 4y = 18
x - 4(27) = 18
x - 108 = 18
x = 18 + 108
x = 126 <== larger number

An oil drilling company is drilling a hole. The elevation of the bottom of the hole changes by feet each day. After a certain nu

marin [14]

Answer:

option.D

Step-by-step explanation:

each day it changes by $-73\frac{1}{4}$

so for two days , the elevation becomes $-73\frac{1}{4}$ + $-73\frac{1}{4}$

for 3 days : $-73\frac{1}{4}$ + $-73\frac{1}{4}$ + $-73\frac{1}{4}$

so, for n days, $-73\frac{1}{4}$ + ........ n times

= n* $-73\frac{1}{4}$

therefore, for x days, elevation = x* $-73\frac{1}{4}$

as it is given that after certain days this elevation has reached $-366\frac{1}{4}$

so, x* $-73\frac{1}{4}$ = $-366\frac{1}{4}$

Answer:

B. -1

Step-by-step explanation:

The relevant points on the graph are (1, 3) and (4, 0). The average rate of change can be found using the slope formula ...

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

m = (0 -3)/(4 -1) = -3/3 = -1

The average rate of change from x = 1 to x = 4 is -1.
