X could be 6 or -2
You start at 2 on a number line and move 4 to the right and 4 to the left.
Answer:
m = -1 (answer (a))
Step-by-step explanation:
Recall that the slope of a straight line is m = rise / run.
As we go from the point (0, -2) to the point (2, -4), we see an increase of 2 in x and a decrease of 2 in y.
Thus, the slope of this line is m = rise / run = 2/(-2), or m = -1 (answer (a))
If circumference = (2 * PI * radius) then we solve for radius
radius = circumference / (2 * PI)radius = 25.142758 / 22/7 * 2radius = <span><span>4.00

In order to answer this item, we must note that if the two angles are congruent then, they have the same measures. Therefore, we equate the given expressions,
<span> 4x – 25 = 2x + 5</span>
The value of x from the equation is 15. Substituting this value to any of the expression will give us an answer of 35. Thus, a measure of angle RQS is 35 degrees.

Answer:
d)
Step-by-step explanation:
Equation of circle with center at point (h, k) and radius, r.
This problem:
(x − A)^2 + (y − B)^2 = C
The center is (A, B).
The radius is sqrt(C).
Answer: d)
