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)

good luck, i hope this helps :)

(A)

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

… ≈ P(Z ≤ 0.1427)

… ≈ 0.5567

(B)

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

… ≈ P(Z > -2.1707)

… ≈ 1 - P(Z ≤ -2.1707)

… ≈ 0.9850

Geometry help please

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!
