The degree of the polynomial is found by looking at the term with the highest exponent on its variable(s). Examples: 5x2-2x+1 The highest exponent is the 2 so this is a 2nd degree trinomial. 3x4+4x2The highest exponent is the 4 so this is a 4thdegree binomial.

Elenna [48]

Answer:

{x,y} = {89/37,-71/37}

Step-by-step explanation:

8x = 3y + 25

[2] x = 3y/8 + 25/8

Plug this in for variable x in equation [1]

[1] 6•(3y/8+25/8) + 7y = 1

[1] 37y/4 = -71/4

[1] 37y = -71

Solve equation [1] for the variable y

[1] 37y = - 71

[1] y = - 71/37

By now we know this much :

x = 3y/8+25/8

y = -71/37

Use the y value to solve for x

x = (3/8)(-71/37)+25/8 = 89/37

Hi can someone help me out with this problem.

Answer:

third side = 9

Step-by-step explanation:

Using Pythagoras' identity on the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

let the third side be x, then

x² + 40² = 41², that is

x² + 1600 = 1681 ( subtract 1600 from both sides )

x² = 81 ( take the square root of both sides )

x = $\sqrt{81}$ = 9

The third side is 9

Answer:

C (2, -1)

Step-by-step explanation:

C has the same x coordinate as A = 2

that eliminates A and B.

and the y value of C has to be closer to the y value of B than to the y value of A (due to the 5:3 ratio).

so, without spending unnecessary effort on actual calculation, we can directly derive the correct answer to be C.

but to show in numbers, the "coordinate triangle" of the difference between D and B is a similar triangle to ACD. and so, the ratio of one side pair applies then to all other sides too. including the individual coordinate differences.

so, also the y difference of A to D relates to the y difference between D and B in the same ratio of 5:3 of the overall y difference of A to B.

the y difference A to B is 2 - -6 = 8

the 5/3 split of 8 units is actually 5 and 3.

so, the y coordinate of D is -6 + 5 = -1

and C must have the same y coordinate.

therefore, it is proven that answer C (2, -1) is the right answer.

Can someone explain how to get to answer B?

sesenic [268]

Yo have to find the distance between point L and point M. First, you have to do the x values. 1 - -3 = 4. Then, you subtract the y values. -2 - 4 = -6. Next, you add the found numbers to the x and y of the midpoint (m). Leaving 1 +4=5 and -2 + -6 = -8.
