Answer:

The answer is false.

Step-by-step explanation:

It is always helpful to rewrite an equation in standard form as a first step in solving it. This is false.

The elimination technique works for the addition and subtraction of equations. For solving linear equations given in slope intercept form, we simply equate the 'y' and solve for 'x'. Then finding y is easy.

X/(x-2) + (x-1)/(x+1) = -1 How to solve?

kirill115 [55]

Multiply entire equation by (x-2)(x+1) to get rid of the denominators That would lead to X(x+1)+(x-1)(x-2)=-1(x-2)(x+1)
Finally, using distributive property and foil, you would get x^2+x+x^2-3x+2=(-x^2+x+2).2x^2-2x+2=-x^2+x+23x^2-3x=0
3x(x-1)x=0 and x=1

The basal energy rate is the daily amount of energy (measured in calories) needed by the body at rest to maintain body temperatu

katovenus [111]

Given :
A = 70 years old
H = 172 cm
W = 55 kg

so calculate the the basal energy rate B
B = 655.096 + 9.563W +1.85H - 4.676A
where B is the basal energy rate (in calories), W is the weight (in kilograms), H is the height (in centimeters), and A is the age (in years)
substitute the given
B = 655.096 + 9.563(55) +1.85(172) - 4.676(70)
B = 1171.941 cal is the basal energy rate, since he is prescribed for 1000 cal per day is not enough because basal energy is the calorie needed at rest only how about the calorie needed for the daily acivities.

A regular hexagon is inscribed in a circle and another regular hexagon is circumscribed about the same circle. What is the ratio

Anna007 [38]

4/3 of the area of the larger hexagon to the area of the smaller hexagon

Let the sides of the interior hexagon be 2 cm long, then this hexagon is made up of 6 equilateral triangles of side = 2.

The area of this hexagon = 6 * 1 * sqrt3 = 6 sqrt3 ( as the triangle is made up of 2 60-30-90 triangles)

The exterior hexagon is made up of 6 equilateral triangles with altitude 2 and the area = 6 * 2 * (2 / sqrt3 ) = 24 / sqrt3

area exterior hex / interior hex = 24 / sqrt3 * 1 / 6sqrt3 = 24/18

= 4/3

Required ratio = 4/3 answer
