Answers

Answer: Chad Makes $1.50 more

Step-by-step explanation:

You have to divide 30 from 4 to see Horatio’s hourly rate which is 7.5 and then you will see that 9 - 7.5 is 1.5. I hope this helped

The monthly cost (in dollars) of water use is a linear function of the amount of water used (in hundreds of cubic feet, HCF). The cost for using 14 HCF of water is $ 32.68 , and the cost for using 52 HCF is $ 95.38 . What is the cost for using 19 HCF of water?

Answers

Answer:

$40.93

Step-by-step explanation:

Given

Linear function of:

14 HCF = $32.68
52 HCF = $95.38

To find:

19 HCF = ?

Solution

Linear equation in slope-intercept form:

y(x) = mx +b

We have points of: (14, 32.68), (52, 95.38):

y(14) = 14 m + b
y(52) = 52 m +b

Using the points we can find the value of m and b:

m= (y2-y1)/(x2-x1)
m= (95.38 - 32.68)/(52 - 14)
m = 62.7/ 28
m= 1.65

Then finding b:

14*1.65 +b = 32.68
b= 32.68 - 23.1
b= 9.58

So the function is:

y = 1.65 x + 9.58

Then y(19) is found as:

y(19) = 1.65*19 + 9.58
y(19) = 40.93

Answer: Cost of 19 HCF of water is $40.93

Answer:

x = -4

x = -6

Step-by-step explanation:

X^2+10x+24=0

(b/2)^2 = (10/2)^2 = 25

X^2+10x+25=-24+25

(x+5)^2 = 1

(x+5) = ± 1

x = +1 -5 = -4

x = -1 -5 = -6
