Moving Company A charges a flat fee of $1200 plus $18 and hour. Company B charges $900 plus $23 an hour. After how many hours would the price be the same regard-less of which company was chosen?

Answers

We need to create two expressions, then equate them in order to find the numbers of hours.


Let X = Number of hours

Let 1200+18x = Company A (Flat Fee + Hourly Rate*Hours)

Let 900+23x = Company B


1200+18x=900+23x\n300+18x=23x\n300=5x\n60=x

Find the y-intercept of y=4(1/3)^x+1+2

Answers

y intercept is where the line crosses the y axis, that only happens when x=0
so set x=0 and find what y intercet is

y=4(1/3)^0+1+2
y=4(1)+1+2
y=4+1+2
y=5+2
y=7


y intercept is y=7 aka the point (0,7)

a bicyclist was traveling from the village to the railroad station with a speed of 15 mph and he was coming back with a speed of 10 mph. find the distance from the village to the railroad station, if it is known that it took 1 more hour for the bicyclist to get back to the village

Answers

Answer:

30 miles. Plug it in. 15 * 2 = 30. 10 * 3 = 30. So this means that the answer to your question is thirty miles.

2x10^21 over 8x10^3

A.2.5x10^6


B. 0.25x10^18

C.2.5x10^17


D.0.25x10^7

Answers

so (2 times 10^21)/(8 times 10^3)
using the associative property
exg
xy/zt=y/z times x/t so

(2 times 10^21)/(8 times 10^3)=2/8 times (10^21)/(10^3)
2/8=1/4=0.25

when dividing exponents, just subtract the bottom number from the top number exg
10^21/10^3=10^(21-3)=10^18

so the answer is 0.25 times 10^18, but

scientific notation is
(a number >1 and <10) times 10^x

so 0.25 times 10=2.5 and 2.5>1 and <10 so this should work

0.25 times 10^18=2.5  times 10^17 ( we just took the ten from the 18)

so the answer is 2.5 times 10^17 or C

What kind of solution(s) do you expect for the linear equation:A. one solution


B. no solution


C. more than one solution

Answers

Answer:

A.) One Solution

Step-by-step explanation:

A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article reviews all three cases. One solution. A system of linear equations has one solution when the graphs intersect at a point.
