Answer:
y = -2x + 4.
Step-by-step explanation:
Use the point-slope form of the equation of a line:
y - y1 = m(x - x1)
Here the slope m = -2, x1 = 3 and y1 = -2 so:
y - (-2) = -2(x - 3)
y + 2 = -2x + 6
y = -2x + 4 (answer).
Answer:
Step-by-step explanation:
Question 1:
x² = -8x - 7
x² + 8x = -7
(x + 4)² = 9
So the answer is (x + 4)² = 9
Question 2:
(x + 4)² = 9
So x = -4 ± 3
Answer:
Tangent line states that a line in the plane of a circle that intersect the circle in exactly one point.
Common external tangent states that a common tangent that does not intersects the line segment joining the centers of circle.
Common internal tangent states that a common tangent that intersects the line segment joining the centers of circle.
Circumscribe polygon states that a polygon with all sides tangent to a circle contained within the polygon.
Therefore:
A polygon with all sides tangent to a circle contained within the polygon = Circumscribe polygon
A common tangent that intersects the line segment joining the centers of circle = Common internal tangent
A common tangent that does not intersects the line segment joining the centers of circle = Common external tangent
a line in the plane of a circle that intersect the circle in exactly one point = Tangent line

Step-by-step explanation:
The answer is:
____________________________
5.778 mi/ h;
→ or; write as: 5 ⁷/₉ mph {"miles per hour"}.
______________________________________
Explanation:
_____________________________________
We shall solve in miles ("mi.") per hour ("h"); denoted as "mi / h" ; or sometimes, "mph".
______________________________________
Given 26 mi / 4.5 h ; we want to solve for the number of miles (mi) per unit hour (h),
________________________________
The answer is (26/ 4.5) mi / h l
______________________________
26 ÷ 4.5 = 5.7777777777777778→ Round to: 5.778 mi/ h;
→ or; write as: 5 ⁷/₉ mi /h
