(10x2 + 99x – 5) ÷ (x + 10) =

The answer to this problem is 10x - 1 with a 5 reminder, which can also be written as 10x - 1 + 5/(x + 10).

To find this, we first have to turn it into a long division problem. First we look to see how many times x goes into 10x^2.

10x^2/x = 10x.

Now we eliminate the first term and multiply the 10x by the second term.

10x * 10 = 100x.

We now subtract that 100x from 99x. This gives us a -x remainder. We can now see how many times x goes into that as well.

-x/x = -1

This gives us the final answer of 10x - 1 with a 5 remainder.

Matrix A = [6 -12 4 8]. What is matrix X if 1/2x=A?

Step2247 [10]

Answer:

$X = \left[\begin{array}{cccc}12&-24&8&16\end{array}\right]$

Step-by-step explanation:

A matrix is given by

$A = \left[\begin{array}{cccc}6&-12&4&8\end{array}\right]$

Now, we have to find the matrix X if $\frac{1}{2} X = A$

⇒ X = 2A

Now, multiplication of a constant with a matrix means multiplication with that constant with all the terms of the matrix.

So, $X = \left[\begin{array}{cccc}6 \times 2&-12 \times 2&4 \times 2&8 \times 2\end{array}\right]$

⇒ $X = \left[\begin{array}{cccc}12&-24&8&16\end{array}\right]$ (Answer)

What are the solutions of -x^2+4x=x-4

Stolb23 [73]

Answer:

x = -1 and x = 4

Step-by-step explanation:

Step 1: Get everything to one side of the equation so it's set equal to zero..

-x² + 4x = x - 4 becomes...

-x² + 3x + 4 = 0 (subtract x and add 4 to both sides)

x² - 3x - 4 = 0 (divide both sides by -1, we want the x² term to be positive)

(x - 4)(x + 1) = 0 (factor)

x - 4 = 0, then x = 4

and

x + 1 = 0, then x = -1

Solve the following: (1 point) 7x − 2y = −3 14x + y = 14

sergeinik [125]

Answer:

Step-by-step explanation:

7x - 2y = -3

14x + y = 14

7x - 2y = -3

28x + 2y = 28

35x = 25

x = 25/35= 5/7

14(5/7) + y = 14

10 + y = 14

y = 4

(5/7, 4)

A baseball player got 52 hits one season. He got h of the hits in one game. What expression represents the number of hits he got

Mars2501 [29]

Answer:

The expression that represents the number of hits he got in the rest of the games is $t=52-h$ .

Step-by-step explanation:

Given:

Number of hits in one season = 52 hits

Number of hits in one game = 'h'

We need to write expression that represents the number of hits he got in the rest of the games.

Solution:

Let the number of hits he got in the rest of the games be 't'.

Now we can say that;

The number of hits he got in the rest of the games is equal to Number of hits in one season minus Number of hits in one game.

framing in equation form we get;

$t=52-h$

Hence expression that represents the number of hits he got in the rest of the games is $t=52-h$ .
