Answer:
There is no power of 4 that is equal to 0.
Step-by-step explanation:
Hence, f(x) = log4^x
does not have a y-intercept.
Answer:
(-9,6)
Step-by-step explanation:
The general equation of a circle is given as:
x²+y²+2gx+2fy+c = 0
The centre of the circle is (-g,-f)
Given the equation of the circle
(x+9)² + (y-6)² = 10²
First we need to expand and write it in the general form. On expansion:
x²+18x+81+y²-12y+36 = 100
Collecting like terms
x²+y²+18x-12y+81+36-100 = 0
x²+y²+18x-12y+17 = 0
Comparing to the general equation
2gx = 18x
g = 9
2fy = -12
f = -6
The center of the circle = (-g, -f)
= (-9,-(-6))
= (-9, 6)
Sounds that you have several answer choices. If that's the case, you need to share those choices. All of them are probably inequalities.
Answer:
w==77
Step-by-step explanation:
The sum of the 2 opposite interior angles equals the exterior angle.
w-36 +w-20=w+21
combine like terms: 2w-56=w+21
subtract w from both sides: w-56=21
add 56 to both sides: <u>w=77</u>
