Find the value of r so the line that passes through the pair of points has the given slope.

SOVA2 [1]

Answer:

The missing value in the ordered pair is 66

Step-by-step explanation:

Given that:

(12,10) and (-2,r)

Slope = m = -4

We have to find the value of r so that the line has a slope of -4.

Slope is the steepness of line which is denoted by m.

Here,

$x_1=12, y_1=10\\x_2=-2, y_2=r$

Putting the values in slope of line formula,

$-4=\frac{r-10}{-2-12}\\ -4=\frac{10-r}{-14}\\$

Multiplying both sides by -14

$-4*-14=\frac{r-10}{-14}*-14\\56=r-10\\56+10=r\\66=r\\ r=66$

The value of r is 66

Hence,

The missing value in the ordered pair is 66

I have 15a but I need 15b and 14

Naily [24]

14. For a prism, the volume is given by
.. V = Bh . . . . . . . . where B is the area of the base, and h is the height of the prism

For a pyramid, the volume is given by
.. V = (1/3)*Bh . . . . where B is the area of the base, and h is the height of the pyramid

The volume is proportional to the area of the base. If the dimensions of the base decrease linearly to zero at the height of the geometry as they do for pyramids and cones, then the volume formula includes a factor of 1/3.

15b. The volume of a pyramid is 1/3 that of a prism with the same base area and height.

write five pairs of integers (a,b) such that a divided / b is equal to 2 is is equal to -3 one such pair is is 6 and -2 because

nataly862011 [7]

Answer:

(10,5), (-12,-6), (-18, -9), (-8, -4), (20,10)

(-15, 5), (-18, 6), (-21,7), (33, -11), (24, -8)

Step-by-step explanation:

10/5=2, -12/-6=2, -18/-9=2, -8/-4=2, 20/10=2

-15/5= -3, -18/6= -3, -21/7= -3, 33/-11= -3, 24/-8= -3
