-9×+1=-x+17 solve equation

gavmur [86]

-9×+1=-×+17
-9×=-×+16 (subtract 1 from both sides)
-8×=16 ( add x to both sides)
×=-2 (divide -8 from both sides)

What is the approximate distance between points D and E? Round your answer to the nearest hundredth.

Usimov [2.4K]

Answer:

C.8.12 units

Step-by-step explanation:

Given the coordinates of two points:

$P1=(x_1,y_1)\\P2=(x_2,y_2)$

The distance between these points is determined by the following equation:

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

We can extract the exact coordinates from the graph provided by the problem:

$P1=D=(x_1,y_1)=(-4,-1)\\P2=E=(x_2,y_2)=(4,-3)$

Therefore:

$d=\sqrt{(4-(-4))^2+(-3-(-1))^2} =\sqrt{(8)^2+(-2)^2} =\sqrt{64+4} =\sqrt{68} \\\\d=8.246211251$

I don't see the correct answer from the choices given. So I would say the most aproximate is C.

Write the point-slope form of the line passing through (2, -12) and perpendicular to y = 3x.

diamong [38]

Answer:

y + 12 = - $\frac{1}{3}$ (x - 2)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

y = 3x is in the form y = mx with slope m = 3

Given the slope of a line m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{3}$

Hence

y - (- 12) = - $\frac{1}{3}$ (x - 2), that is

y + 12 = - $\frac{1}{3}$ (x - 2) ← in point- slope form
