First, you want to find out what the slope and the y-intercept is, you must put both equations in y=mx+b from.

<em>6x − 14y = −28</em>                    :First, subtract the 6x over to the right
<u>-6x</u>                   <u>-6x</u>

<u>(</u><em>-14y = -6x - 28</em><u>)</u> <u>÷ -14</u>         :Then, divide the whole equation by -14

<em>y = 6/14x + 2</em>                        :Now, reduce the fraction, divide both the top and the                                                 bottom by 2

<em>y = 3/7x + 2</em>
<span>
3y − 7x = −14                      :First, add the 7x over to the right side
</span>      +7x          +7x

(3y = 7x - 14) ÷ 3                 :Next, divide the whole equation by 3

<em>y = 7/3x - 14/3
</em>


y = 3/7x + 2             slope: 3/7     y-int.: 2

y = 7/3x - 14/3         slope: 7/3     y-int.: -14/3 or -4 7/10 or -4.7

C.  Your answer is C.  They will eventually intersect, but not at a right angle.

Give the center and radius of the circle x2+y2=25
Arisa [49]

Answer:

B) (0,0); r=5

Step-by-step explanation:

A circle's standard form is (x-h)^2+(y-k)^2=r^2

The center is (h, k) and the radius is r.

So, here the center would be (0, 0) and the radius would be square root 25, or 5.

You can rent a ski boat for $20 plus $35 per hour. If you want to spend no more than $150, how many hours can you rent a ski boa
elena-s [515]

Answer:

h ≤ (approx) 3.7

Step-by-step explanation:

To start, we can take our knowledge that we have to spend 20$, at minimum. Therefore, we can only allocate (150-20)=130 to our payment per hour. As we pay 35$ per hour, the amount of money relative to hours would be 35*h. Therefore, as we can allocate 130 dollars or less for our hourly payments, and our money is 35*h, we can day that 35*h(the money we spend on hourly rates) ≤ 130. Then, as 35*h ≤ 130, we can divide 35 from both sides to get h ≤ 130/35, or h ≤ (approx) 3.7
