Mathematics
1 answer:
vladimir1956 [14]3 years ago
5 0

Answer:

The correct answer is (-5,-5)

Step-by-step explanation:

1. Both of the equations are in standard form, so first you set them equal to each other.

2. Solve for x as a normal algebraic equation.

3. Back substitute your answer for x into one of the original equations. (back substitution is just putting the x back into the equation and solving for y.)

4. Now you have your x and y coordinates, and the point of intersection of the two lines.

A flower pot has a diameter of 6 feet. What is the area of the flower pot, to the nearest whole number?
Elodia [21]

Answer:

28 ft²

Step-by-step explanation:

The area of a circle is \pi r^2, where r = radius. To find the radius, we split the diameter in half.

  • 6/2 = 3
  • Thus, the radius is 3.

Now, let's find the area of the circle and approximate pi to 3.14.

  • 3.14*3^2
  • 3.14*9
  • 28.26
  • 28.26 ≈ 28 ft²

Therefore, the answer is 28 ft².

Estimate the area of a circle with a radius of 21 meters. Use 22/7 for pi. (1 point)
V125BC [204]
A=\pir^{2}

A=(\frac{22}{7})(21^{2})

A=(\frac{22}{7})(441)

A=\frac{22}{7})(\frac{441}{1})

A=\frac{9702}{7}

A=1386 square meters

The answer is B.

The graph of F(x) can be flipped over a certain line to produce the graph of its inverse. What is the equation of that line?
OlgaM077 [116]
<span><u><em>The correct answer is: </em></u>
y=x.

<u><em>Explanation: </em></u>
<span>In order to find the inverse of a function, we first <u>switch x and y</u>; then we isolate y. When we do this, we are saying that x and y equal the same thing, or y=x.  </span></span>

Will give brainliest <br> A ?<br> B?<br> C ?
dolphi86 [110]

Answer:

A: 180°         B: 360°         C: 540°

Step-by-step explanation:

A: The measures of interior angles of a triangle sum to 180°. Since figure ABC is a triangle, the interior angles of figure ABC sum to 180°.

B: We can see the quadrilateral ACDE is a trapezoid. If you can see, the trapezoid can be split into two triangles if you connect points C and E. As U mentioned before, the measures of interior angles of a triangle sum to 180°. Since we know figure ACDE can be split into <u>two triangles</u> we have to do: 180x2 which is 360°.

C: Now that we know the Pentagon ABCDE can be split into 3 triangles(1 from figure ABC and 2 from figure ACDE), we have to multiply 180 by 3 because like I mentioned before, the measures of interior angles of a triangle sum to 180°. So, 180x3=540°.
