Answer:

m∠B = 69°

General Formulas and Concepts:

  • Order of Operations: BPEMDAS
  • Equality Properties
  • Complementary Angles add up to 90°

Step-by-step explanation:

<u>Step 1: Define</u>

m∠A = (x + 9)°

m∠B = (7x - 15)°

<u>Step 2: Set up equation</u>

m∠A + m∠B = 90°

(x + 9)° + (7x - 15)° = 90°

<u>Step 3: Solve for </u><em><u>x</u></em>

  1. Combine like terms:                    8x - 6 = 90
  2. Add 6 to both sides:                    8x = 96
  3. Divide both sides by 8:                x = 12

<u>Step 4: Find m∠B</u>

  1. Define:                    m∠B = (7x - 15)°
  2. Substitute:              m∠B = (7(12) - 15)°
  3. Multiply:                  m∠B = (84 - 15)°
  4. Subtract:                 m∠B = 69°

3 Questions Math! HELP!!!

1) Since the larger number is a negative, you’re going to get a negative solution for number one. An easy way to do the math is to ignore the negative sign in (-116) For a moment. And subtract 56 from it.
116 - 56 = 60. Don’t forget to place the negative sign we pushed to this side before the solution. The answer is -60.

2) We do the same thing we did in number one, but with new numbers. The answer in total is -178.

3. As stated, we do the same thing we did in number one. Just because there’s a decimal doesn’t change much. And your answer would be -1.1

Roman55 [17]
If you know how to divide by decimal you have to divide 55 ÷ 4.5 and you would get 12 but if you don't know keep multipling a number times 4.5 but overall if you don't want to do all the work the answer is going to be (55×4.5=12 or 4.5×12=55— 12 houses)

Gelneren [198K]

Answer:

802,000

Step-by-step explanation:

The number in the thousands place is 1, and the number to the right of it is 5. And if the number to the right is greater than or equal to 5 the place value that you are rounding goes up by one.

What is the end behavior of the function f of x equals 3 times the cube root of x? as x → –[infinity], f(x) → –[infinity], and a
geniusboy [140]

The function f(x)=4\sqrt[3]{x} is a cube root function and the function end behavior is: x → + ∞, f(x) → + ∞, and as x → - ∞, f(x) → + ∞

<h3>What is end behavior?</h3>
  • The end behavior of a function f defines the behavior of the function's graph at the "ends" of the x-axis.
  • In other words, the end behavior of a function explains the graph's trend when we look at the right end of the x-axis (as x approaches +) and the left end of the x-axis (as x approaches ).

To determine the end behavior:

  • The equation of the function is given as: f(x)=4\sqrt[3]{x}
  • To determine the end behavior, we plot the graph of the function f(x).
  • We can see from the accompanying graph of the function:
  • As x approaches infinity, so does the function f(x), and vice versa.
  • As a result, the function end behavior is:  

x → + ∞, f(x) → + ∞, and as x → - ∞, f(x) → + ∞

Therefore, the function f(x)=4\sqrt[3]{x} is a cube root function and the function end behavior is: x → + ∞, f(x) → + ∞, and as x → - ∞, f(x) → + ∞

The complete question is given below:

What is the end behavior of the function f of x equals negative 4 times the cube root of x?

As x → –∞, f(x) → –∞, and as x → ∞, f(x) → ∞.

As x → –∞, f(x) → ∞, and as x → ∞, f(x) → –∞.

As x → –∞, f(x) → 0, and as x → ∞, f(x) → 0.

As x → 0, f(x) → –∞, and as x → ∞, f(x) → 0.
