Answer:
centre = (2, - 4 ), radius = 3
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x - 2)² + (y + 4)² = 9 ← is in standard form
with centre = (2, - 4 ) and r = [tex]\sqrt{9}[/tex] = 3

3. If bº = 110°, what is the value of gº?
Answers
Answer:
hello mate <3
u see here its a quadrialteral
with 4 angles b , d , 70 , g
so b + d + 70 + g = 360
now u see 60 + d = 180 (straight line)
d = 120 and b = 110 ( given)
so
110 + 120 + 70 + g = 360
g + 300 = 360
g = 360 - 300 = 60 degrees option c

Choose the congruence theorem that you would use to prove the triangles congruent
Answers
Answer:
It would be the HL theorum.
Step-by-step explanation:
The answer would be the HL theorum by just considering the name. "HL" stands for Hypotenuse-leg. The problem tells you that both triangles share the same length of their hypotenuse (The Hypotenuse is the line with one dash in it, or the one opposite of the 90 degree angle) and one of the legs (The legs are the lines that connect to make the 90 degree angle). This makes the triangle congruent because if 2 sides of a triangle are the same it means that the third one is congruent as well.

If f(x) = -2[x] + 8, what is f(-1.8)?
O 4
O 6
O 10
O 12
Answers
Answer:
12
Step-by-step explanation:
since the function is -2x+8 and you have been told to find f(-1.8) you have to replace -1.8 were there's x in the function.
f(x)=-2x+8
f(-1.8)=-2x+8
=-2(-1.8)+8
=3.6+8
=11.6 round off to 12

y = 3x + 2
Answers
x = 3y + 2
Then, we solve for y
We can first subtract 2 on both sides
x - 2 = 3y
Then we can divide by 3 on both sides to get
x/3 - 2/3 = y
So our final equation is
y = x/3 - 2/3

m = (-2 - 6)/(3 - 5) = -8/-2 = 4The second one:
m = (-7 - 4)/(4 - (-3)) = -11/7Answer:
Step-by-step explanation:
1) (x₁,y₁) = (5 , 6) & (x₂,y₂) = (3 , -2)
[tex]Slope = \dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\dfrac{-2-6}{3-5}\\\\=\dfrac{-8}{-2}\\\\=4[/tex]
