If mADC and mBDC have a sum of 180, name the straight angle.

Graph the system of equations on graph paper to answer the question. Y=2/5x+4 and y=2x+12 what is the solution for this system o

riadik2000 [5.3K]

Answer:

Solution of the given equations is (-5,2)

Step-by-step explanation:

We have been given the following system of equations:

y = (2/5)x + 4

y = 2x + 12

The solution of the system of equation can be found by finding the point of intersection of both lines on the graph. The graph of both equations is attached below.

As we can see that both the lines intersect each other at one point, and that point is (-5,2). So the solution of the given equations is (-5,2)

Is the expression 3x^2-5x^3 a Polynomial? If yes, what is the degree?

Paraphin [41]

Answer: The answer is: it is a fifth degree binomial or 'quintic binomial'.

Step-by-step explanation:

Is the expression 3x^2-5x^3 a polynomial?

So, we have to know what polynomial means. A polynomial is... "an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables."

So let's take a look at this expression.

Does it consist of variables and coefficients? YES

Does it only involve operations of addition, subtraction, multiplication, and non-negative integer exponents of variables? YES

Therefore, it is a polynomial.

Now, we have to figure out what degree this polynomial is.

The degree of the polynomial is the degree of the monomial with the largest degree.

So the largest degree would be the 3rd degree, because it is, of course, the largest out of the two powers listed.

And also, keep in mind that this is a binomial (made up of two monomials).

Therefore, it is a fifth degree binomial or 'quintic binomial'.

Artist 52 [7]

Answer:

(1) 12 boxes (2) 1173 points

Step-by-step explanation:

(1) Jamie needs to fit all if his toys in the boxes, so you would need to do 103 times 9, making it 11.4. So, you'd need twelve boxes to fit all of he toys into boxes.

(2) The contestant earned 69 points, and each of those points are worth 17 points, meaning you have to do 17 times 69, which is 1173 .

The amount of stretch in a short bungee cord stretches 6 inches when stretched by a 3pound weight. A slinky stretches 3 feet whe

aleksklad [387]

Answer:

The slinky situation

Step-by-step explanation:

To make a rate, divide one value by the other.

For the short bungee,

6 inches ÷ 3 pound = 2 inches per pound

While the slinky,

36 inches (remember to convert feet to inches) ÷ 1 pound = 36 inches per pound

As you can tell by the numbers, 36 inches per pound is way better than the 2 inches per pound.
