Answer:

x = -3, y = -7

Step-by-step explanation:

Eliminate the equal sides of each equation and combine.

Solve 2x - 1 = 3x + 2 for x.

-x - 1 = 2

-x = 3

x = -3

Evaluate y when x = -3

y = 3 (-3) + 2

y = -7

(-3, -7)

P(<em>X</em> < 61.25) = P((<em>X</em> - 55.4)/4.1 < (61.25 - 55.4)/4.1)

… ≈ P(<em>Z</em> ≤ 0.1427)

… ≈ 0.5567

(B)

P(<em>X</em> > 46.5) = P((<em>X</em> - 55.4)/4.1 > (46.5 - 55.4)/4.1)

Hello!

The equation to find the volume of a cone is

\pi  r^{2}  \frac{h}{3}

r is radius
h is height

Put in the values we know

3.14 *  9^{2} *  \frac{4}{3}

Square the number

3.14 * 81 *  \frac{4}{3}

multiply 81 by 3.14

254.34 *  \frac{4}{3}

Multiply

339.12

The answer is 339.1 cubic inches

Hope this helps!
