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= $\pi$ $r^{2}$

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]

The correct answer is: 
y=x.

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

Will give brainliest A ? B? 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 two triangles 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°.
