Answer:

Y= -8

X= 3

Step-by-step explanation:

apply -(-a)=a rule

-23+4*8/3

-23+4*8=9

9/3

=3

Answer:

x = 3

y = -8

Step-by-step explanation:

We have two simultaneous equations:

3x + 4y = -23

2y - x = -19

Solve for y in the second equation.

2y = -19 + x

y = -19/2 + 1/2x

Put y as -19/2 + 1/2x in the first equation and solve for x.

3x + 4(-19/2 + 1/2x) = -23

3x + 2x - 38 = -23

5x - 38 = -23

5x = -23 + 38

5x = 15

x = 15/5

x = 3

Put x as 3 in the second equation and solve for y.

2y - 3 = -19

2y = -19 + 3

2y = -16

y = -16/2

y = -8

What is the value of X?
d1i1m1o1n [39]

Answer:

x=10

Step-by-step explanation:

We can use the angle bisector theorem to solve this problem

8             12

-------- = ---------

x+4         2x+1

Using cross products

8(2x+1) = 12(x+4)

Distribute

16x+8 = 12x+48

Subtract 12x from each side

16x -12x +8 = 12x-12x +48

4x +8 = 48

Subtract 8 from each side

4x+8-8 = 48-8

4x = 40

4x/4 = 40/4

x=10

Find the difference quotient and simplify your answer. f(x) = 4x − x2, f(4 + h) − f(4) h , h ≠ 0
Anon25 [30]

The difference quotient and simplification will be    = [4 -h-2x]

The given equation is as follows:   f(x)= 4x - x²

For finding the quotient and further simplification we must follow the following steps:

[f(x + h) - f(x)] / h = [4(x + h) - (x + h)² - 4x + x²]/ h

<h3>What is simplification of algebraic operations?</h3>

Getting the functions in their lowest terms is known as simplification.

Brackets will get open and solved further;

[f(x + h) - f(x)] / h = [4(x + h) - (x + h)² - 4x + x²]/ h

[f(x + h) - f(x)] / h = [4h - h² - 2x]/ h  

Finally dividing the whole equation with h;

                                = [4 - h - 2x]

Matt bought a home in 2001 and paid $150,000 for it. He sold the home for $450,000. How much of the profit on his home will be t
butalik [34]

Answer:

profit to be taxable will be  $300,000

Step-by-step explanation:

Matt home cost = $150,000

Matt sold his home for = $450,000

so,

cost price will  be  $150,000

selling price will be $450,000

         profit = selling price - cost price

         profit  =  $450,000  -  $150,000

         profit  =  $300,000

hence the taxable amount for his home this year will be $300,000
