What is m (There is no multiple choice just find m

Mathematics
1 answer:
Sauron [17]4 years ago
4 0

Answer:

160 degrees.

Step-by-step explanation:

Line ABC is a straight line, and the angle on a straight line is always 180 degrees.

Since ABD + DBC = ABC, we know that x+8x=180

9x=180

Divide both sides by 9:

x=180\div 9=20

DBC is 8x=8\times 20=160 degrees.

Solve and sketch its graph<br> 1. 3x^2 - 4x = 0
Neko [114]

Step-by-step explanation:

By solving, I am assuming that you want to find the zeros.

So to find what x equals, first, you factor out an x.

3x² - 4x = 0

x(3x - 4) = 0

Here, you can separate the equation into two different equations to solve for x.

  • <em>3x - 4 = 0</em>           and              <em>x = 0</em>
  • 3x = 4
  • x = \frac{4}{3}                   and               x = 0

Those are your zeros.

And for its graph, you can always look to an online graphing calculator. I used Desmos.

B(1)=16 <br> b(n)=b(n-1)+1 <br> Find the second term in the sequence
anyanavicka [17]

Answer:

17

Step-by-step explanation:

b(n)=b(n-1)+1 means a term can be found by taking it's previous term and adding 1 to it.

So if b(1)=16, the next term b(2)=16+1=17.

1/2 (5-2h) = h/2, solve for h
Brilliant_brown [7]

Answer:

h = 1 2/3

Step-by-step explanation:

1/2 (5-2h) = h/2

Multiply each side by 2

(5-2h) = h

Add 2h to each side

(5-2h +2h) = h+2h

5 = 3h

Divide by 3

5/3 = 3h/3

5/3 =h

1 2/3 = h

Check

1/2 (5-2*5/3) = 5/3/2

1/2 ( 5 - 10/3) = 5/6

1/2 ( 15/3 - 10/3) = 5/6

1/2 ( 5/3) = 5/6

5/6 = 5/6
