Mathematics
1 answer:
Alenkasestr [34]4 years ago
6 0

Answer:

G(5)= 5

Step-by-step explanation:

r is 5, so you input it into the r next to -3, so you should have 20-3(5), and -3 times 5 is -15. You subtract -15 with 5 and the answer should give you 5.

I need help with these please... anyone?
Svetlanka [38]
The total measure of the interior angles of each figure will be:

180 (n-2) = 180 (4 - 2) = 360

Now add all those angles and set them equal to 360.

41 + 133 + 86 + x = 360

x is the unknown angle.

260 + x = 360
x = 100

The missing angle that is Not labeled in any of the figure is 100°

Hope this helps :)

What is x squared equals one twenty one
Iteru [2.4K]

Answer:

x = 11

Step-by-step explanation:

x² = 121

You are solving for the variable, x. Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x. Root both sides:

√(x²) = √(121)

x = √121 = √(11 * 11)

x = 11

x = 11 is your answer.

A triangle has one side that lies along the line y=1/4x and another that lies along the line y=-1/4x. Which of the following poi
mestny [16]

Answer:

We know that our triangle has one side along the line:

y = (1/4)*x

And other side along the line:

y = -(1/4)*x.

Now, we want to find the vertex.

And we know that the vertex is the point where the two sides conect, so the vertex must be a common point of both lines.

Then we have:

y = (1/4)*x = -(1/4)*x

x = -x

The only solution to that equation is x = 0.

now we evaluate our lines in x = 0 and get:

y = (1/4)*0 = 0

y = -(1/4)*0 = 0

Then the lines intersect in the point (0, 0)

Then the vertex must be in the point (0, 0)
