Answer:

Company B will charge cheaper in 5 hours

Step-by-step explanation:

Step one:

Given data

Company A

charges $25 per hour and a $300 equipment fee

let the total be

A= 300+25t---------------1

Company B

charges $50 per hour and a $125 equipment fee.

let the total be

A= 125+50t---------------2

put t = 5 in the two expressions above

A= 300+25t---------------1

A= 300+25*5

A=300+125

A=$425

B= 125+50t---------------2

B= 125+50*5

B=125+250

B=$375

Answer:

A = 25t + 300 B = 50t + 125

company B is $50 cheaper than company A for 5 hours of landscaping

Answer:

__________________the answer is C _____________

Answer:

C.

Step-by-step explanation:

The y intercept is when x=0

so (0, -7) is the y-intercept

slope is found when you subtract y-y1/x-x1

-10- (-7) / 9-0

-3/9

simplified is -1/3

slope is -1/3 and y intercept is (0, -7)

Complete question :

A fish is swimming at a constant rate toward the ocean floor. The equation y = -7x - 3 can be used to represent this situation, where y is the depth of the fish in meters below sea level and x is the number of seconds the fish has been swimming

Which statement best describes the depth of the fish

From a starting position of 7 meters below sea level, the fish is descending 3 meters per second.

From a starting position of 7 meters below sea level, the fish is ascending 3 meters per second.

From a starting position of 3 meters below sea level, the fish is descending 7 meters per second.

From a starting position of 3 meters below sea level, the fish is ascending 7 meters per second.

Answer:

From a starting position of 3 meters below sea level, the fish is descending 7 meters per second.

Step-by-step explanation:

Given the equation :

y = - 7x - 3

y = depth of fish in meters ; x = Number of seconds fish has been swimming

From the equation ; which is written according to the slope - intercept equation, ; y = mx + c

The slope, m = - 7 is the rate of change in y per unit of x

c = intercept, constant, value of y when x = 0

Hence, the true statement in the equation is :

-7 represents descent and meams fish descents at a rate of 7 m per second

At x = 0, the fish is at a depth of 3 m

Step-by-step explanation:

The first and second hour the pay is $9.50/hour, but in the third hour the pay is $11/hour. Then in the fourth hour it changes again to $10/hourIf there was a proportional relationship there would need to be a constant rate of change in pay.

Answer:

Yes, the proportional relationship is 9.50

-24 ==== ( 2×-6=-12___-12×2= -24)

Step-by-step explanation:

You can insert different values of x to find y

For example:

x = 4

Plug in x into the equation

y = -1/2(4) + 5

y = -2 + 5

y = 3

So your point will be (4, 3)

If you do 1 more like this, you can draw a line between them. Or you can use Desmos to graph the line.

Answer:

36

Step-by-step explanation:

Conjugate of z = -3-5i

Therefore the expression is equivalent to (-3+5i)(-3-5i).

(-3+5i)(-3-5i)

=9-(-25)

=36

Answer:

z (the conjugate of z) = 34

Answer:

Her height would be 162.56 centimeters tall.

Step-by-step explanation:

There are 12 inches in 1 foot so that would mean that 1 foot has 30. 48 centimeters.

30.48 x 5 = 152.4

Add the 4 extra inches so 4 inches in centimeters is 10.16

152.4 + 10.16 = 162.56

Answer:

(-5,8)

Step-by-step explanation:

The given equation y = -3x - 7 holds true for the ordered pair, so (-5, 8) is a solution. Thus, option third is correct.

To determine whether each ordered pair is a solution to the equation y = -3x - 7, we substitute the x and y values into the equation and check if it holds true.

For the ordered pair (8, -56):

y = -3x - 7

-56 = -3(8) - 7

-56 = -24 - 7

-56 = -31

The equation does not hold true for this ordered pair, so (8, -56) is not a solution.

For the ordered pair (-5, 8):

y = -3x - 7

8 = -3(-5) - 7

8 = 15 - 7

8 = 8

The equation holds true for this ordered pair, so (-5, 8) is a solution.

For the ordered pair (-9, -23):

y = -3x - 7

-23 = -3(-9) - 7

-23 = 27 - 7

-23 = 20

The equation does not hold true for this ordered pair, so (-9, -23) is not a solution.

For the ordered pair (4, 19):

y = -3x - 7

19 = -3(4) - 7

19 = -12 - 7

19 = -19

The equation does not hold true for this ordered pair, so (4, 19) is not a solution.
