Answer:

y = 3x - 1

Step-by-step explanation:

Given the data set: (1, 2) (2, 5) and (3, 8), you first need to look for a constant difference in the values of x and y:

x: 1   2   3  (add '1' each time)

y: 2  5  8  (add '3' each time)

Rate of change (slope) can be found by dividing y/x:

3/1  = 3

Since y = 2 when x = 1, then y = -1 when x = 0.  

Using slope-intercept formula: y mx + b

y = 3x - 1

I just tried working this one out and I can’t find the answer. Maybe nothing further can be determined that I know so far.

Divide: –65.86 ÷ (–7.4)
Rina8888 [55]

Answer:

8.9


Step-by-step explanation:

The answer is 8.9 because two negatives divided by each other equals a positive. In this case, there are two negatives so you know the answer will be a positive. In the end when you divided –65.86 ÷ (–7.4), you get 8.9!

Hope this helps, have a good day. c;

(You can also type it into your calculator if you have one, and you should hopefully get the same answer.)

State if each angle is an inscribed angle. If it is, name the angle and the intercepted arc.
LUCKY_DIMON [66]

Answer:

<em>No, there are no inscribed angle in this diagram; Option D</em>

Step-by-step explanation:

<em>~ Let us apply process of elimination to solve this problem ~</em>

Option 1. This first example states firstly that m∠SRT is an inscribed angle. That is not true, by definition an inscribed angle is an angle created by two chords that share a common endpoint. Neither RS nor RT are chords, in fact they each are radii, creating a central angle instead.

Option 2. m∠RST is not created by two chords, instead by arc ST and radii RS ⇒ and I believe I am not familiar with what angle it is reffered to, if at all it is named.

Option 3. As stated before, ∠SRT is not an inscribed angle; by definition an inscribed angle is an angle created by two chords that share a common endpoint, and neither RS nor RT are chords.

Option 4. Through elimination, Option D is the only possible answer left: <em>Answer: No, there are no inscribed angle in this diagram</em>

Step-by-step explanation:

you would bring the 3.98 over to the other side, so it would be -3.98+6.58=2.6-8.39=-5.76
