Find the slope and the y-intercept of the equation y − 3(x − 1) = 0.

In this problem, we need to isolate the y variable. To do so, we can first distribute the -3 into the (x-1) to get y - 3x + 1 = 0.
Then, we can add 3x - 1 to both sides of the equation, making it:
y = 3x - 1
This is a linear equation in the form of y = mx + b. The m, 3 in this equation, is the slope. The b, -1 in this equation, is the y-intercept.
The slope is 3.
The y-intercept is -1.

<span>y − 3(x − 1) = 0.
y - 3x + 3 = 0
y = 3x - 3

slope m = 3
y-intercept (0, -3)</span>

Find the value of b.

Answer: $230^{\circ$

Step-by-step explanation:

For convenience, I labeled some points as shown in the attached picture.

Also, I assume $\overline{AB}$ and $\overline{BC}$ are tangents to the circle.

$\overline{BO} \cong \overline{BO}$ (reflexive property)
$\overline{AB} \cong \overline{BC}$ (tangents drawn from a common external point are congruent)
$\angle BAO \cong \angle BCO$ (right angles are congruent)

Therefore, we know $\triangle ABO \cong \triangle CBO$ by HL.

Thus, by CPCTC,

$\angle AOB \cong \angle BOC \implies m\angle BOC=65^{\circ}\\\\\implies m\angle AOC=130^{\circ}$

This means the measure of minor arc AC is $130^{\circ}$ , and thus $b=360^{\circ}-130^{\circ}=\boxed{230^{\circ}}$

Sound travels about 335 meters/second. How many kilometers would a sound travel in 1 minute?

Lelechka [254]

If sounds travel 335 meters in 1 second , in 1 minute it travels 60 times that distance :

335m × 60 = 20100 meters
Sounds travel 20100 meters per minute
if 1000 meters = 1 km ,
20100 meters = 20100/1000 km
20100 meters = 20.1 Km

Awnser : Sound would travel 20.1 km in one minute

Find the distance between each pair points (-5,3) , (-4,-5)?

tester [92]

The distance formula is d=√(x2-x1)² + (y2-y1)²

So... d =8.06226

Hope this helps
