2x - 2(4x-3) = 6 - 6x

Mathematics

1 answer:

sergejj [24]3 years ago

4 0

Answer:

Step-by-step explanation:

Open parenthesis first:

2x-8x+6=6-6x

Combine like terms:

-6x+6=6-6x

Then move all like terms to one side:

6-6=-6x+6x

Simplify:

0=0

0=0 is true, so x can equal any number and the result will be true. (Like the number 4, for example. If x was 4, you would get 4=4.)

5 5/6 ÷ 3 3/4 - 2/9=

Ray Of Light [21]

Answer:

$\boxed{ \: ans = \frac{5}{9} }$

Step-by-step explanation:

$5 5/6 ÷ 3 3/4 - 2/9 \to \: \frac{35}{6} \div \frac{15}{4} - \frac{2}{9} \\ \frac{35}{6} \times \frac{4}{15} - \frac{2}{9} \\ \frac{7}{9} - \frac{2}{9} \\ \boxed{ \: ans = \frac{5}{9} }$

Which linear inequality is shown on the graph?

AlekseyPX

Answer: choice C) x-y <= 2

======================================

Explanation:

The two points (0,-2) and (2,0) are on the boundary line. The boundary line equation is y = x-2. We find this equation through the use of the slope formula to find that m = 1. The y intercept is -2 so b = -2. Therefore, y = mx+b turns into y = 1x+(-2) which simplifies to y = x-2

The equation y = x-2 can be arranged to get x-y = 2 (subtract y from both sides; add 2 to both sides)

So the answer is either x-y <= 2 OR it is x-y >= 2

The question is: which inequality has the test point (0,0) in it? We pick on the origin since 0 is the easiest number to work with.

Plug (x,y) = (0,0) into the equation for choice C
x-y <= 2
0-0 <= 2
0 <= 2
which is true. So choice C is the answer.

Choice D can be ruled out since...
x-y >= 2
0-0 >= 2
0 >= 2
which is false: 0 is not larger or equal to 2

what is (5.91 x 10^-3) - (8.7 x 10^10) written in a scientific notation? Please answer asap thank you :))

nata0808 [166]

Answer:

Please check the explanation.

Step-by-step explanation:

Given the expression

$\left(5.91\times \:10^{-3}\right)-\left(8.7\times \:10^{10}\right)$

$\mathrm{Remove\:parentheses}:\quad \left(a\right)=a$

$=5.91\times \:10^{-3}-8.7\times \:10^{10}$

$5.91\times \:10^{-3}$

$\mathrm{Apply\:exponent\:rule}:\quad \:a^{-b}=\frac{1}{a^b}$

$=5.91\times \frac{1}{10^3}$

$=\frac{5.91}{1000}$

$=0.00591$

similarly

$8.7\times \:10^{10}$

Convert element to a decimal form

$10^{10}=10000000000$

$=10000000000\times \:8.7$

$\mathrm{Multiply\:the\:numbers:}\:8.7\times \:10000000000=87000000000$

$=87000000000$

Thus, the expression becomes

$\left(5.91\times \:\:10^{-3}\right)-\left(8.7\times \:\:10^{10}\right)=5.91\times \:\:10^{-3}-8.7\times \:\:10^{10}$

$=0.00591-87000000000$

$=-86999999999.9941$

Hence,

converting -86999999999.9941 in a scientific notation

In order to make our job easier we will remove the sign "-" from number -86999999999.9941 (we will write "-" at the final solution). So after this step we have:

−86999999999.9941 ⟶ 86999999999.9941

In order to write number 86999999999.9941 in scientific notation, we need to move the decimal point from its current location (black dot) to the new position such as:

8.6999999999.9941

So, we need to move the decimal point 10 places to the right.

This means that the power of 10 will be positive 10.

Now we have that the

Number part = 8.69999999999941 and

Exponent part = 10

Thus, we conclude that:

−86999999999.9941 = − 8.69999999999941 × 10¹⁰

Need NOW PLEASE.....

____ [38]

Answer:

8-(-8) = 8+8

8-8 = 8+(-8)

-8-(-8) = -8+8

-8-8 = -8+(-8)

10-9 = 10+(-9)

10-(-9) = 10+9

Step-by-step explanation:

Remember that if the signs are equal +,+ or -,- , they are positive (+)

if the signs are different like +,- or -,+ then they are negative (-)
