Answer:
x = 1/2
Step-by-step explanation:
Combine exponents
4x-x-2=-3^2+3xx
4x-x-2=-3x^2+3x^2
Combine like terms
4x-2=-3x^2+3x^2
4x-2=0
Add 2 to both sides
4x-2=0
4x-2+2=0+2
Simplify:
Add the numbers
4x-2+2=0+2
4x=0+2
Add the numbers again
4x=0+2
4x=2
Divide both sides by the same factor
4x=2
4x/4 = 2/4
Simplify:
Cancel terms that are in both the numerator and denominator
4x/4 = 2/4
X= 2/4
Divid the numbers
X= 2/4
X= 1/2
Solution/ Answer
x= 1/2

Hope this helps

Answer:

x =  - 4

Step-by-step explanation:

4x - 2 =  - 3 \times 2 + 3x

Calculate the product:

4x - 2 =  - 6 + 3x

Rearrange the terms:

4x - 3x =  - 6 + 2

Combine like terms:

x =  - 6 + 2

Calculate:

x =  - 4

A square picture with side length 30 cm is scaled by 60% on a photocopier the copy is then scaled by 60% again. What is the side
Sonja [21]

Answer:

10.8 cm

Step-by-step explanation:

we know that

1) A square picture with side length 30 cm is scaled by 60% on a photocopier

Remember that

60\%=60/100=0.60

so

The length of the first copy of the picture is

30(0.60)=18\ cm

2) The copy is then scaled by 60% again

so

The length of the second copy of the picture is

18(0.60)=10.8\ cm

Solve the system restrictions by graphing if there is no solution or an infinite number solutions so state you set notation to e
Bingel [31]

Answer:

  (x, y) = (4, 16)

Step-by-step explanation:

The first equation is a proportion, so you know right away that (0, 0) is on the graph. Pick any value you like for x, and y will be 4 times that. So, for example, the point (5, 20) will also be on the graph of y=4x.

The second equation has a y-intercept of 20 and a slope of -1. So, however many unit to the right of the y-axis you choose to go, the y-value will be down that number of units from 20. In addition to (0, 20), the point (5, 15) will be on the graph of y = -x+20.

__

Personally, I like to use a graphing calculator to show the graphical solution.

Here, the solution is (x, y) = (4, 16).

Is the answer to (-1)^2-(-2-(9-1)), <br><br> 11?
yulyashka [42]

Answer: Yes that's correct

Work Shown:

(-1)^2-(-2-(9-1))

1-(-2-(8))

1-(-2-8)

1-(-10)

1 + 10

11

Note that (-1)^2 = (-1)*(-1) = 1, and subtracting a negative turns into a positive.
