Answer:

Desmos is Function Calculator is a great tool for this, the correct answer is z= 7/3

7/3= 2.333~ and so √(3*2.333~) + 2= 2.9999999833333~

Now 7- 2.9999999833333~= 4.0000000166667~ but I don't know the true infinate sign for this so thats why my numbers look a little weird, just plug (7/3) in for z and you will get 4, trust me

A line has a slope of -13. There is a second line that passes through points (-7,-5) and (6,-4) . Would these lines be parallel

Elza [17]

<h3>Answer: The lines are perpendicular</h3>

=================================================

Work Shown:

Use the slope formula to find the slope of the line through the two given points.

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

m = (-4 - (-5))/(6 - (-7))

m = (-4 + 5)/(6 + 7)

m = 1/13

The slope of the line through the two given points is 1/13.

This is not equal to -13, which was the slope of the first line, so the two lines are not parallel.

However, the two lines are perpendicular because multiplying the two slope values leads to -1

(slope1)*(slope2) = (-13)*(1/13) = -1

note: It might help to think of -13 as -13/1 to help multiply the fractions.

A parking lot charges $3 to park a car for the first hour and $2 per hour after that. If you use more than one parking space, th

Vikki [24]

Given, a parking lot charges $3 for first hour and $2 per hour after that.

So for t hours, the parking lot charges $3 for the first hour and after first hour there is $(t-1)$ hours left.

So for $(t-1)$ hours it will charge $2 per hour.

The charges for $(t-1)$ hours = $ $2(t-1)$ .

Total charges for t hours for one car = $ $(3+2(t-1))$

Now for the second car, it will charge 75% of the first car.

So the charges for second car

=$[ $(3+2(t-1))(75/100)$ ]

=$ $0.75(3+2(t-1))$

There are 3 cars. That parking charges for the third car is also 75% of the first car.

So for third car the parking charges are same as for the second car.

Total parking charges for 3 cars

= $ $(3+2(t-1))+(0.75(3+2(t-1))+(0.75(3+2(t-1))$

= $ $(3+2(t-1))+(0.75)(2(3+2(t-1))$

We have got the required answer here.

The correct option is option C.
