If an x intercept only touches the x axis it means it has a multiplicity of 2. If an intercept goes through the axis it has a mu
Dima020 [189]

If the multiplicity is even, the x-intercept will touch the x-axis and turn away (sometimes people call this "kissing" the x-axis). If the multiplicity is odd, the intercept will go right through the x-axis, so the answer to your question is false. In general, remember that odd crosses and even touches/turns/kisses.

Find the area of the sector.
attashe74 [19]

Answer: C . 147π / 4 mi²

Concept:

The sector is the part of a circle is enclosed by two radii of a circle and their intercepted arc.

A = (θ / 360) πr²

θ = angle of the sector

π = constant

r = radius

Solve:

<u>Given variable</u>

θ = 270°

r = 7 mi

<u>Given formula</u>

A = (θ / 360) πr²

<u>Substitute values into the formula</u>

A = (270 / 360) π (7)²

<u>Simplify exponents</u>

A = (270 / 360) π 49

<u>Simplify by multiplication</u>

A = (147 / 4) π

A = 147π / 4

Hope this helps!! :)

3x – y = -1 x – 2y = -12
Leviafan [203]

The solution to the system of equation is (2, 7)

<h3>System of equation</h3>

Given the  system of equation expressed as:

3x – y = -1  * 2

x – 2y = -12 * 1

________________

6x – 2y = -2

x – 2y = -12

Subtract to have;

6x-x = -2-(-12)

5x = 10

x = 2

Substitute x = 2 into 2 to have:

2 - 2y = -12

-2y = -14

y = 7

Hence the solution to the system of equation is (2, 7)
