Answer:

hope this helps

Step-by-step explanation:

Heat can be transferred from one place to another by three methods: conduction in solids, convection of fluids (liquids or gases), and radiation through anything that will allow radiation to pass. The method used to transfer heat is usually the one that is the most efficient.

Answer:

$x + y = 1042$

$1.5x + 0.75y = 1140$

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

x is the number of regular fares paid.

y is the number of reduced fares paid.

1,042 total fares were paid

This means that $x + y = 1042$

A city bus collected $1,140 in fares on a given day. The regular fare is $1.50, and the reduced fare is $0.75.

This means that:

$1.5x + 0.75y = 1140$

System of equations:

The system of equations is:

$x + y = 1042$

$1.5x + 0.75y = 1140$

Answer:

Step-by-step explanation:

To do this, you need to complete the square.

$y=-2x^2-8x-13 \\\\y=-2(x^2+4x)-13 \\\\y=-2(x^2+4x+4)+8-13 \\\\y=-2(x+2)^2-5$

Therefore, the correct answer is choice B. Hope this helps!
