Comparing the temperature of a coolant before and after use in a machining process.

Step-by-step explanation:

The temperature of a coolant in the polar region was found to be modeled by the equation t=(8x-55)° where t is the final fluid temperature after being used for cooling ,x is the time the fluid is applied on the cutting edge and -55 is the normal temperature of the fluids used for cooling processes in a machine garage.

What is the x-intercept (-5,-5) (10,-2)

Andre45 [30]

Answer:

(20,0)

Step-by-step explanation:

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

(-5,-5).....x1 = -5 and y1 = -5

(10,-2)...x2 = 10 and y2 = -2

slope = (-2 - (-5) / (10- (-5) = (-2 + 5) / (10 + 5) = 3/15 = 1/5

y = mx + b

slope(m) = 1/5

use either point, I will use (10,-2)...x = 10 and y = -2

now we sub

-2 = 1/5(10) + b

-2 = 2 + b

-2 - 2 = b

-4 = b

so the equation for this line is : y = 1/5x - 4

to find the x intercept, sub in 0 for y and solve for x

y = 1/5x - 4

0 = 1/5x - 4

-1/5x = -4

x = -4 * -5

x = 20.......so ur x intercept is (20,0) <====

Cabrina and Dabney are attending a conference. After the conference, Cabrina drives home to Boise at an average speed of 7575 m

kifflom [539]

Answer:

Cabrina's time = 5 hours

Dabney's time = 6.5 hours

Step-by-step explanation:

The data of the exercise are:

Cabrina speed = 75 mph

Daney speed = 60 mph

The sum of their distance is 765 miles, therefore

Cabrina's distance Dabney's distance = 765

Cabrina's distance = x

Dabney's distance = 765-x

The sum of their times is 11.5 hours, therefore

Cabrina's time Dabneys time = 11.5

Cabrina's time = x / 75

Dabney's time = (765-x) / 60

x / 75 (765-x) / 60 = 11.5

Lowest common denominator of 75 and 60 is 300, therefore we have:

330 * x / 75 300 * (765-x) / 60 = 300 * 11.5

4 * x 5 * (- x 765) = 3450

4 * x - 5 * x 3825 = 3450

x = 375

Replacing:

Cabrina's time = 375/75 = 5 hours took

Dabney's time = (765-375) / 60 = 6.5 hours took
