4x= -2x -6
Isolate the x terms on one side, by adding "2x" to each side, resulting in
6x = -6
Then divide both sides by 6, so
x = -1

sertanlavr [38]

The data used consists Standing/Walking time (minutes per day) spent by two types of people (Lean and Obese).

<h3>How to illustrate the data?</h3>

The claim is that lean people spend more time walking and standing than obese people. We will be using right-tailed test.

The steps include:

  • Collect a sample of both groups
  • Calculate the mean and standard deviation of the two groups
  • State the null and alternate hypothesis and alpha.
  • Calculate Test Statistic
  • Make a conclusion based on our test.

The orthocenter of an obtuse triangle always lies __________.
aev [14]

The intersection of three altitudes of a triangle is called the orthocenter, while altitude is the line drawn from one of the vertex of a triangle and extends it in such a way that it cuts perpendicularly the opposite side of the same triangle.

<span> For obtuse triangle, the orthocenter always lies outside of the triangle. So option “C” is correct. </span>

<span>An image of obtuse triangle along with orthocenter is attached herewith.</span>

Write an inequality for the shaded region shown in the figure.​
Snezhnost [94]

Answer:

y ≥  x^2 - 1

Step-by-step explanation:

First, we can see that the shaded region is above what seems to be a parabola, and we also can see that the lines of the parabola are solid lines (which means that the points on the curve itself are solutions, so the symbol ≥ is used)

Then:

y ≥ a*x^2 + b*x + c

where a*x^2 + b*x + c is the general quadratic equation.

Now let's find the equation for the parabola:

f(x) = a*x^2 + b*x + c

We also can see that the vertex of the parabola is at the point (0, -1)

This means that:

f(0) = -1 = a*0^2 + b*0 + c

     = -1 = c

then we have that c = -1

Then:

f(x) = a*x^2 + b*x - 1

Now we can look at the graph again, to see that the zeros of the parabola are at +1 and -1

Which means that:

f(1) = 0 = a*1^2 + b*1 - 1 = a + b - 1

f(-1) = 0 = a*(-1)^2 + b*(-1) - 1 = a - b - 1

Then we got two equations:

a + b - 1 = 0

a - b - 1 = 0

from this we can conclude that b must be zero.

Then:

b = 0

and these equations become:

a - 1 = 0

a - 1 = 0

solving for a, we get:

a = 1

Then the quadratic equation is:

f(x) = 1*x^2 + 0*x - 1

f(x) = x^2 - 1

And the inequality is:

y ≥  x^2 - 1

Which diagram shows lines that must be parallel lines cut by a transversal? 2 horizontal lines are intersected by a third line.
ivanzaharov [21]

Answer:

  (A)  At the intersection of the first line with the third line, the bottom left angle is 115 degrees. At the intersection of the second line with the third line, the uppercase left angle is 65 degrees.

Step-by-step explanation:

Alternate interior angles are supplementary when parallel lines are crossed by a transversal. The first description seems to be describing alternate interior angles. (See attachment)

_____

<em>Comment on orientation</em>

If the transversal is oriented horizontally, then the descriptions of the angles will be of different angles than assumed here.
