Find the equation of a line that contains the points (−3,−1) and (−4,−7). Write the equation in slope-intercept form

ikadub [295]

Answer:

y = -8x -25

Step-by-step explanation:

The 2-point form of the equation of a line is useful when you are given 2 points.

y = (y2 -y1)/(x2 -x1)(x -x1) +y1

y = (7 -(-1))/(-4 -(-3))(x -(-3)) +(-1)

y = 8/-1(x +3) -1

y = -8x -25

A polygon has the following coordinates: A(3,1), B(5,3), C(2,5), D(-1,5), E(-4,3), F(-2,1). Find the length of DC.

nlexa [21]

To find the length of a line given two points, we are going to use the distance formula, which is defined below:

$D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

( $(x_1, y_1)$ and $(x_2, y_2)$ are the two points)

The points in this problem are (2, 5) and (-1, 5). We can find the distance of DC by substituting these values into the distance formula and simplifying, as shown below:

$D = \sqrt{(-1 - 2)^2 + (5 - 5)^2$

Substitute values into formula

$D = \sqrt{(-3)^2}$

Combine like terms and then simplify $0^2$ to 0

$D = \sqrt{9}$

Compute $(-3)^2 = 9$

$D = 3$

Compute $\sqrt{9} = 3$

The length of DC is 3.

Which is a better estimate for the weight of a dresser?<br> 45 grams or 45 kilograms

STatiana [176]

45 grams is about 1/4 cup of water or maybe 1/4 cup of flour or uncooked rice would be 45 grams. Anyway it's not much.

Unless the dresser is made of paper, 45 grams is not enough. 45 kg though large (that's roughly 100 pounds if that's what you think in), the dresser might be found in the apartment where Sherlock Holmes lives. (The dresser is a piece of victorian furniture) it is much closer to what a modern dresser would weigh.

Please help and explain how to do this. thank you in advance!

Sholpan [36]

We want to solve
$3e^{2x}+5=27$

Subtract 5 from each side.
$3e^{2x}=22$
Divide each side by 3.
$e^{2x}=7.3333$
Take natural logs of each side.
$2x=ln(7.3333)=1.9924$
Divide each side by 2.
x = 0.9962

Answer: x = 0.996 (nearest thousanth)
