Your answer would be 128!

(17/8, -1/8) or if you want it in decimals  (2.125, -0.125)2x-6y=5                    x+y=2      y=2-x2x-6(2-x)=52x-12+6=58x-12=58x=17x=17/8(17/8)+y=2   You plug in the x-value to find the y-value now y=2-17/8y=-1/8

What is the constant term of the quotient when 2x^3-3x^2 + 4x-2 is divided by x^2-x+2?
AlladinOne [14]

Answer:

  -1

Step-by-step explanation:

See the attachment for the polynomial long division. The constant in the quotient is -1.

_____

Here, there is a remainder of -x. If there were no remainder the constant in the quotient is the ratio of the constant in the dividend to the constant in the divisor: -2/2 = -1.

That could be a first guess in a "guess and check" solution approach.

<em>Guess</em>: first term of binomial quotient is (2x^3)/x^2 = 2x; last term of binomial quotient is -2/2 = -1. So, the quotient is guessed to be (2x -1).

<em>Check</em>: (2x -1)(x^2 -x +2) = 2x^3 -3x^2 +5x -2

Subtracting this from the actual dividend gives a remainder of -x. This has a lower degree than the divisor, so no further adjustment of the quotient is required.

Charlotte is solving the following equation for X (x+3)^2-10=2 her first steps are given below (x+3)^2=12 x+3= + square root 12
Katarina [22]

The values of the x in the given equation are x = 6.46 and x = -0.46

<h3>Solving an equation </h3>

From the question, we are to solve the equation for x

The given equation is

(x+3)² -10 = 2

First, add 10 to both sides of the equation

(x+3)² -10 +10 = 2 +10

(x+3)²  = 12

Now, take the square root of both sides to get

x + 3 = ±√12

∴ x = 3 ± √12

x = 3+√12 OR 3-√12

x = 3 + 3.46 OR 3 - 3.46

x = 6.46 OR -0.46

Hence, the values of the x in the given equation are x = 6.46 and x = -0.46

a car moves 35 miles per hour travels a distance of 51.3 feet each second. about how far does a car travel in 7.1 seconds ?
Sergio039 [100]
If you would like to know about how far does a car travel in 7.1 seconds, you can calculate this using the following steps:

51.3 feet ... 1 second
x feet = ? ... 7.1 seconds

51.3 * 7.1 = x * 1
x = 51.3 * 7.1
x = 364.23 feet

The correct result would be 364.23 feet in 7.1 seconds.
