Answer:

answer is 10, 4 and 8

as y = x-4,

6 = x-4

6 + 4 = x

x = 10 for first

similarly,

0= x-4

4+0=x

x= 4 for the second

for the third,

4 = x-4

4+4=x

so x=8

WILL GIVE BRAINLIEST IF CORRECT ANSWER!!!

Answer : 2√3

Given :-

A equilateral triangle with side length 4.

To Find :-

The value of x in the given figure.

As we know that in a equilateral triangle , perpendicular bisector , angle bisector and median coincide with each other .

So the perpendicular drawn in the figure will bisect the given side .
Therefore the value of each half will be 4/2 = 2 .

Now we may use Pythagoras theorem as ,

→ AB² = BC² + AC²

→ 4² = 2² + x²

→ 16 = 4 + x²

→ x² = 16-4

→ x² = 12

→ x =√12 = √{ 3 * 2²}

→ x = 2√3

Hence the required answer is 2√3 .

I hope this helps.

Do you prefer to express solutions to inequalities using interval notation or as an inequality ? Do you think it’s important to

docker41 [41]

Answer:

I prefer to express solutions to inequalities using interval notation. Both formats are are important but I think interval notation is easier to understand and represents better the solutions.

For example, if you have the following inequation:

x-2> 1

x>3

Therefore, the solution could be written either x>3 OR (3, +inf). But what happens if the solution to the system of equation is x>3 or x<-3? The solution can be easily written as: (-inf, -3) U (3, inf) instead of 'x>3 or x<-3' which is more confusing.

Tamara is planting bushes around her house. So far today she has planted 5 bushes and she wants to plant at least 12 bushes toda

Naya [18.7K]

Answer:

b+5 ≥ 12

Step-by-step explanation:

Let the additional bushes to be planted be represented by a variable b

Since Tamara already planted 5 bushes, 5 will be a constant in the inequality ;

So,

b+5 ≥ 12 will be the inequality used to find number of bushes.

Simplify: log base 3 (1/3) ...?

yarga [219]

The answer is 1.

$log_3( \frac{1}{3} )$
_____
Since $log_y(x) = \frac{log_{10}(x)}{log_{10}(y)}$ , then: $log_3( \frac{1}{3} )= \frac{log_{10} ( \frac{1}{3}) }{log_{10}(3)}$
_____
Since $\frac{1}{x} = x^{-1}$ , then: $\frac{log_{10} ( \frac{1}{3}) }{log_{10}(3)} = \frac{log_{10}(3^{-1} )}{log_{10}(3)}$
_____
Since $log x^{a} =a*logx$ , then: $\frac{log_{10}(3^{-1} )}{log_{10}(3)}= \frac{-1*log_{10}(3)}{log_{10}(3)}$

From here: $\frac{-1*log_{10}(3)}{log_{10}(3)}=-1*\frac{log_{10}(3)}{log_{10}(3)}=-1*1 = -1$
