When system of equations solved graphically, the solutions are points of interceptions, So here, the solution is the point of interception (0,-5).
Answer (0,-5).

Answer:
Step-by-step explanation:
There are a couple of relations that are applicable to these questions.
- the product of segment lengths of crossed chords is the same for both chords
- the angle formed at crossed chords is the average of the intercepted arc measures
__
The segment lengths relation tells us ...
10x = 8×7 . . . . . . products of segment lengths are equal
x = 56/10 = 5.6 . . . . divide by 10
__
The value of y° is the average of the intercepted arcs:
y° = (85° +45°)/2 = 65°
_____
<em>Additional comment</em>
This diagram does not have enough information to allow computation of z. We would need to know the intercepted arc, or the length of the secant that meets tangent z.
Answer:
-1
Step-by-step explanation:
3 • 7 = 21
Find two factors of 21 whose sum equals the coefficient of the middle term, which is -1 .
-21 + -1 = -22
-1 + -21 = -22
1 + 21 = 22
21 + 1 = 22
Answer:
2
Step-by-step explanation:
2 is the slope of y=2x+3 and any line parralel would have the same slope. therefore the parallel slope would be 2
the operation:
Gives a square number.

How to get a perfect square?</h3>
A perfect square is the product of a number and itself.
As you can see in the example, 16 is a square number. Then let's try to get 16.
To get 16 we can use the difference:
20 - 4
So the first therm needs to be equal to 20, and the second equal to 4.
To write 20 in scientific notation we have:
To write 4 in in scientific notation:
Then the operation:
Gives a square number.
