The expression xy-2, when x=3 and y= -4, becomes    (3)(-4)-2, or -14 (answer)

the expresion 3x^2*y - 4 becomes 3(3)^2*(-4) - 4, or 27(-4) - 4, or -108 - 4 = -112 (answer)

Leave Timmy out of this, since it seems he didn't really do anything.    ;)

Find the midpoint of the line segment that has endpoints at (10,8) (-3,-10)
dem82 [27]

Hey there! :)

Answer:

(3.5, -1).

Step-by-step explanation:

Use the midpoint formula to solve this problem:

(x_m, y_m) = (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})

Plug in the coordinates given:

(\frac{10-3}{2}, \frac{8-10}{2})

Simplify:

(\frac{7}{2}, \frac{-2}{2})

Therefore, the coordinates of the mid-point are:

(3.5, -1).

a cube has sides with the following number: 3,3,6,9,,7,8. what is the probability of getting a factor of 9 when rolled?
muminat

Answer:

The probability of rolling a factor of 9 is 1/2, or 50%.

Step-by-step explanation:

The number 9's factors are 1, 3, and 9. Three of the six sides of the cube have a factor of 9. Therefore 3/6 of the sides are factors of nine.

Simplify 3/6 to 1/2 to get a probability of 50%.
