Answer:
(x+9)^2+(y+5)^2=81
Step-by-step explanation:
(x-h)^2+(y-k)^2=r^2
(h,k)=center
r=radius
so if you just insert the center (-9,-5) and the r with 9
(x-(-9))^2+(y-(-5))^2=9^2
(x+9)^2+(y+5)^2=81
Hope that helps :)
Answer:
Angle bisector
Step-by-step explanation:
median isn't applicable in this case as the roads from the streets are inclined at an angle.
altitude refers to height which is also not applicable
The perpendicular bisector is the locust of points equidistant from two points,
in this question the street are not seen as points but as lines which forms an angle and the bisection of this angle forms a locus where she can park her car. If she parks her car anywhere on the angular bisector of the two streets, she would be at equal distance from both streets.
2. PX=QX ----------- Definition of bisector.
3. AXP and AXQ ----------- Definition of perpendicular.
4. AXP=AXQ ------------- All right angles are congruent.
6. AXP=AXQ ------------ SAS congruence
7. AP=AQ -------------Corresponding parts of congruent triangles
Just took the test!!!!
Answer:
9(x + 3)
Step-by-step explanation:
Answer:
Factorising the equation into brackets can help you identify where the x-intercepts are (where the function cuts the x-axis)
Step-by-step explanation:
When you factorise the equation it would look something like this:
(x + a)(x + b) = 0
This also means:
x + a = 0 and x + b = 0
x = -a and x = -b
Example:
Find where the function y = 2x² + 8x + 6 cuts the x-axis
Factorise the 2 out (highest common factor)
x² + 4x + 3 = 0
(x + 1)(x + 3) = 0
x = -1 or -3
