Answer & Step-by-step explanation:

In order to find the y-intercept of this equation, we must turn this equation into a slope-intercept equation. The equation for slope-intercept form is <em>y=mx+b. </em>We can do this by using these steps. Our goal is to get y by itself on one side.

6x - 2y - 9 = 0

Step 1: Add 9 on both sides of the equation.

6x - 2y = 9

Step 2: Subtract 6x on both sides of the equation. Once you subtract, make sure you put the -6x in front of 9 so we are following the rules of variables and exponents.

-2y = -6x + 9

Step 3: Divide -2 on both sides of the equation.

y = 3x - \frac{9}{2}

So, the y-intercept is -\frac{9}{2}

avanturin [10]
<h3>It costs $ 22.5 for mike and his friend to rent paddle board for 3 hours</h3><h3>Mike has $ 2.5 remaining after rental</h3>

<em><u>Solution:</u></em>

Given that,

Mike has $25.00 to rent paddleboards for himself and a friend for 3 hours

Each paddleboard rental costs $3.75 per hour

So there are two persons = mike and his friend

1 hour = $ 3.75

Therefore, for 3 hours:

3 \times 3.75 = 11.25

<em><u>Thus for two person:</u></em>

11.25 + 11.25 = 22.5

Thus it costs $ 22.5 for mike and his friend to rent paddle board for 3 hours

Remaining amount = 25 - 22.5 = 2.5

Thus Mike has $ 2.5 remaining after rental

Suppose a triangle has two sides of length 3 and 4 and that the angle
rodikova [14]

Answer:

B

Step-by-step explanation:

We can use the law of cosinse:

c^{2} = a^{2} + b^{2} − 2ab cos(C)

Suppose the two sides are a and b, and the angle betweent them is C.

c^{2} = 3^{2} + 4^{2} − 2*3*4 cos(60)

We can simplify this to get c^{2} =25-12=13

c=\sqrt{13}

Answer choice B

Simple easy problem pls help
Nastasia [14]
Hello!

To find the answer, you'll first need to find how many gears that can be made in a hour. You can do this by dividing 2088 by 8. Once you've done that, there will be 261 gears being made every hour. Now you'll need to multiply 261 by 9 to see how many gears will be made n 9 hours. Once you've done that, you'll have your answer.

In 9 hours, there are 2349 gears that are made

I hope this helps!

During the Labor Day weekend, Amy and Kathleen each ran in a race. Amy ran in a 5K and completed it in 31 minutes and 15 seconds
Novosadov [1.4K]
Velocity=distance/time

a=5/(31*60+15)=5/1875=1/375

k=21.1/(2*3600+11*60+52.5)=21.1/7912.5=1/375

a=k

The both ran at the same speed.

(1km/375s)(3600s/h)=9.6km/h
