Find an equation of a line passing through the point (8,9) and parallel to the line joining the points (2,7) and (1,5).
TiliK225 [7]

Answer:

2x - y - 7 = 0

Step-by-step explanation:

Since the slope of parallel line are same.

So, we can easily use formula,

y - y₁ = m ( x ₋ x₁)

where, (x₁, y₁) = (8, 9)

and m is a slope of line passing through (x₁, y₁).

and since the slope of parallel lines are same, so here we use slope of parallel line for calculation.

and, Slope = m = \dfrac{y_{b}-y_{a}}{x_{b}-x_{a}}

here, (xₐ, yₐ) = (2, 7)

and, (y_{a},y_{b}) = (1, 5 )

⇒ m = \dfrac{5-7}{1-2}

⇒ m = 2

Putting all values above formula. We get,

y - 9 = 2 ( x ₋ 8)

⇒ y - 9 = 2x - 16

⇒ 2x - y - 7 = 0

which is required equation.

Jamal will slice a right circular cylinder into to congruent pieces. Which two-dimensional plane section could result from the s
Debora [2.8K]

Answer:

1st Option is correct that is we get circle after slicing a right circular cylinder in small pieces.

Step-by-step explanation:

Given: Jamal Sliced aright circular cylinder into congruent pieces.

To find: Shape of Two-Dimensional plane section obtained after slicing.

We get congruent pieces only when we slice the cylinder parallel to its base at equal heights.

By doing this we get small pieces of cylinders of equal height and equal radius.

Base and top remains same that is circular in shape.

Therefore, 1st Option is correct that is we get circle after slicing a right circular cylinder in small pieces.

Zolol [24]

Answer:

h(-6) = 3(-6)² - 6(-6) + 4

= 3(36) + 36 + 4

= 148

You basically just substitute x with -6 that's all
