Answer:

Below in bold.

Step-by-step explanation:

If I have interpreted the question correctly it is:

3*3*3*3 *x*x*x*x = 34

81 x^4 = 34

x^4 = 34/81

x = +/- (⁴√34) / 3 is the exact answer , or:

x = +/- 0.805 to nearest thousandth.

Determined to find the slope<br>(1,7K) and (-3,5k)

Nadusha1986 [10]

9514 1404 393

Answer:

slope = k/2

Step-by-step explanation:

The slope formula is useful for finding slope.

m = (y2 -y1)/(x2 -x1)

m = (5k -7k)/(-3 -1)

m = -2k/-4

m = k/2

The slope is k/2.

Use the construction in proof of the Chinese reminder theorem to find all solutions to the system of congruence:

antoniya [11.8K]

Answer:

17,101,185, 269,.... is the solution.

i.e. x≡17 mod(84) is the solution

Step-by-step explanation:

Given that the system is

$x ≡ 2 ( mod 3 )x ≡ 1 ( mod 4 )x ≡ 3 ( mod 7 )$

Considering from the last as 7 is big,

possible solutions would be 10,17,24,...

Since this should also be 1(mod4) we get this as 1,5,9,...17, ...

Together possible solutions would be 17, 45,73,121,....

Now consider I equation and then possible solutions are

5,8,11,14,17,20,23,26,29,...,47,....75, ....

Hence solution is 17.

Next number satisfying this would be 101, 185, ...

Complete this equation 2 2/3 +4/5= 40/? + 12/? = ?/?

OlgaM077 [116]

Answer:(7/8 - 4/5)^2 = 9

1600

= 0.005625

Step-by-step explanation:

Subtract: 7

- 4

= 7 · 5

8 · 5

- 4 · 8

5 · 8

= 35

- 32

= 35 - 32

= 3

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(8, 5) = 40. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 8 × 5 = 40. In the next intermediate step the fraction result cannot be further simplified by cancelling.

In words - seven eighths minus four fifths = three fortieths.

Exponentiation: the result of step No. 1 ^ 2 = (3

) ^ 2 = 32

402

= 9

1600

In words - three fortieths squared = nine one-thousand six-hundredths.

What is the solution to |x − 4| ≥ 7?

Snowcat [4.5K]

9514 1404 393

Answer:

(x ≤ -3) ∪ (11 ≤ x)

Step-by-step explanation:

The given equation resolves to two equations:

x -4 ≥ 7 ⇒ x ≥ 11

x -4 ≤ -7 ⇒ x ≤ -3

The solution is (x ≤ -3) ∪ (11 ≤ x).
