Multiply the top equation by 6 and the bottom equation by 7. You will cancel x first by doing this and solve for y. You should get y=-1.
Substitute in y for either original equation.
You should get x=1.
Solution is (1,-1).

Writing this word problem symbolically: 6x + 4 = x = 11.

Combining like terms, 5x = 7, and so x = 7/5 (answer)

What's the following rotational symmetries of oranges regular hexagon

Semmy [17]

Answer:

rotational symmetry of 60 degrees around the origin - yes

rotational symmetry of 120 degrees around the origin - yes

Step-by-step explanation:

A regular hexagon has 6 congruent angles

the the angles created on the line of symmetry are equal to 60 so the angle of rotational symmetry is 60 degrees.

The regular hexagon, like stated before, has 6 congruent angles so the order of symmetry is 6

Here is a visual from basic-matematics

Can someone tell me what 1/2 - 1/6 is would really appreciate it, thanks

timama [110]

Make denominator same first.

1/2 - 1/6

3/6 - 1/6

Now subtract numerators

(3-1) / 6

2/6

Now simplify

1/3

Final answer: 1/3

Write 1-2log7x as a single logarithm

slavikrds [6]

Answer:

$log_{7} \frac{7}{x^{2} }$

Step-by-step explanation:

We need to write $1 - 2log_{7}x$ as a single logarithm.

We know that

$log_{7}7 = 1$

Therefore we have:

$log_{7}7 - 2log_{7}x$

→ $log_{7}7 - log_{7}x^{2}$

→ $log_{7} \frac{7}{x^{2} }$

The solution is: $log_{7} \frac{7}{x^{2} }$
