Hello and Good Morning/Afternoon:

Let's take this problem step-by-step:

Since this is an algebraic problem

⇒let's solve it like one

$2*3^{x+5} < 14\\3^{x+5} < 7\\ x+5 < log_37\\x < -5 + log_37\\x < -3.2288$

Answer: x < -3.2288

Hope that helps!

When setting up a proportion to calculate scale drawings, how do you write the proportion? A)actual/actual B)actual/drawing C) d

Semmy [17]

When setting up a proportion to calculate scale drawings, how do you write the proportion? A)actual/actual B)actual/drawing C) drawing/drawing D)drawing/actual

The correct answer is option D: drawing/actual

Suppose there is a drawing that has a scale of 1:10. So, this means anything drawn with the size of "1" would have an actual size of "10" in the real world, so a measurement of 120mm on the drawing would be 1200mm on the actual/real image.

In the triangle below find X round to the nearest 10th

denis-greek [22]

According to the trigonometric relations in a right triangle, we have:

$\begin{gathered} \cos x=\frac{9}{17} \\ x=\cos^{-1}\frac{9}{17} \\ x\approx58.0\degree \end{gathered}$

What is the midpoint to the segment below?

shtirl [24]

Step-by-step Answer:

The coordinates of the mid-point of a segment whose end-points are known is the average of the coordinates of the end-points.

Here, the end-points are: (-11,0), (9,-1)

So the x-coordinate of the mid-point is (-11+9)/2 = (-2/2) = -1, and

the y-coordinate of the mid-point is (0-1)/2 = -0.5

So the mid-point is (-1,-0.5)

Check the numbers by plotting the point on the graph!

I need help with this geometry question asap!

dybincka [34]

Answer:

True

Step-by-step explanation:

Lines in three dimensions can be one of ...

coincident
parallel
intersecting (at one point)
skew

<h3>Coplanar</h3>

Lines are coplanar when a plane can be defined that includes the entirety of both of them. In the attached image, lines m₁ and n intersect and both lie in the gray plane. They are coplanar.

Lines m and m₁ are parallel, and both are contained in the turquoise plane. They are coplanar. A plane can always be drawn that will contain a pair of parallel lines. That is, any two parallel lines must be coplanar.

The lines m and n in the figure are skew, non-intersecting and non-parallel. They cannot be contained in a single plane.

Additional comment

Three or more parallel lines may not be coplanar. They will only definitely be coplanar when considered in pairs.
