63

Step-by-step explanation:

Hi there!

In order to find the answer to this question we must know about:

The angles of intersecting chords theorem

The theorem states that if two chords intersect the angles formed at the intersection is equal to half the sum of its intercepted arc and it's vertical angle's intercepted arc.

Angle ABC is formed by intersecting chords meaning that the measure of angle ABC is equal to half the sum of its intercepted arc + it's vertical angle's intercepted arc ( angle ABC vertical angle is angle EBD. Angle EBD's intercepting arc is arc ED. )

Angle ABC intercepted arc is AC

Hence Angle ABC = 1/2 ( arc AC + arc ED)

Arc ED = 44 and arc AC = 82

Thus, angle ABC = 1/2(82 + 44)

82 + 44 = 126

126/2=63

Hence Angle ABC = 63

Two functions, f and g, are represented by these function machines.

Gennadij [26K]

Answer:

x = -2

Step-by-step explanation:

Since we know they will have the same output, we can set them equal to each other in an equation. We'll use x to represent the input.

3x + 6 = 8(x + 2) (Given)

3x + 6 = 8x + 16 (Distributed the 8)

6 = 5x + 16 (Subtracted 3x on both sides)

-10 = 5x (Subtracted 16 on both sides)

-2 = x (Divided 5 on both sides)

Find the error with this proof and explain how it mat be corrected in order to clearly prove the equation.

enyata [817]

Answer:

Step-by-step explanation:

It is true that for any given odd integer, square of that integer will also be odd.

i.e if $m$ is and odd integer then $m^{2}$ is also odd.

In the given proof the expansion for $(2k + 1)^{2}$ is incorrect.

By definition we know,

$(a+b)^{2} = a^{2} + b^{2} + 2ab$

∴ $(2k + 1)^{2} = (2k)^{2} + 1^{2} + 2(2k)(1)\\(2k + 1)^{2} = 4k^{2} + 1 + 4k$

Now, we know $4k^{2}$ and $4k$ will be even values

∴ $4k^{2} + 1 + 4k$ will be odd

hence $(2k + 1)^{2}$ will be odd, which means $m^{2}$ will be odd.

- 3x – 8 + 4x = 17<br> Please help

Lerok [7]

Answer:

x=25

Step-by-step explanation:

Combine like terms which would make it

x-8=17

Move over the 8 by adding it to each side

x=17+8

And then add them together

x=25
