Find the equation of the line through the point ( 3 , − 7 ) that is perpendicular to the line with equation y = x − 12 .
Answer: y = -x - 4
Step-by-step explanation:
A perpendicular line has a slope that is the negative inverse of the reference line, which is y = x-12. The slope here is 1, so the negative inverse would be -1/1, or -1. The perpendicular line would therefore be:
y = -1x + b
We can find b by using the given point (3,-7) as a solution:
y = -1x + b
-7 = -1*3 + b
b = - 4
The equation is therefore y = -x - 4
(x^2 + 2x + 2)(x + 5) = 0

Determine whether the following statement is always, sometimes, or never true. Explain your reasoning.
Every complex number has both a real part and an imaginary part.
The statement "Every complex number has both a real part and an imaginary part" is always true.
Every complex number is defined as a number of the form "a + bi," where "a" represents the real part and "bi" represents the imaginary part.
The real part "a" is a real number, and the imaginary part "bi" is a multiple of the imaginary unit "i," where "i" is defined as the square root of -1.
Even if a complex number has a zero imaginary part, it is still considered to have both a real and an imaginary part.
In that case, "a" represents the real part, and the imaginary part "bi" becomes zero.
For example, the complex number 3 + 0i is a real number (3) and can be represented as having a real part of 3 and an imaginary part of 0i.
In conclusion, every complex number by definition consists of both a real and an imaginary part, making the statement "Every complex number has both a real part and an imaginary part" always true.

1.Find the value of f(–9) and g(1) if f(x) = 8x + 6 and g(x) = 9x + 20x−2
A.f(–9) = 14
g(1) = 30
B.f(–9) = –78
g(1) = –11
C.f(–9) = –66
g(1) = 29
D.f(–9) = 8
g(1) = –80.75
2.Find the value of f(–9) and g(–1) if f(x) = –3x – 2 and g(x) = 3x3 – 24x .
A. f(–9) = 25
g(–1) = 21
B.f(–9) = –5
g(–1) = 20
C.f(–9) = 29
g(–1) = 26
D.f(–9) = 3
g(–1) = –27
Answer:
1. f(–9) = -66 , g( 1 ) = 27 (Please double-check your given options, there must have been a typographical error for Option C for g( 1 ) = 29). g( 1 ) is supposed to be 27.
2. Option A: f(–9) = 25, g(–1) = 21
Step-by-step explanation:
1.Find the value of f(–9) and g(1) if f(x) = 8x + 6 and g(x) = 9x + 20x−2
f(x) = 8x + 6
f(–9) = 8(-9) + 6 = -66
g(x) = 9x + 20x − 2
g( 1 ) = 9( 1 ) + 20( 1 ) − 2 = 27
None of the given choices were correct (unless there's a typo error for Option C — it's supposed to be g( 1 ) = 27 instead of 29?) because the correct answers are: f(–9) = -66 and g( 1 ) = 27
2. f(–9) and g(–1) if f(x) = –3x – 2 and g(x) = 3x³ – 24x
f(x) = –3x – 2
f(–9) = –3(–9) – 2 = 25
g(x) = 3x³ – 24x
g(–1) = 3(–1)³ – 24(–1) = 21
Therefore, the correct answer is Option A: f(–9) = 25, g(–1) = 21

not possible
Step-by-step explanation:
Answer:
-17
Step-by-step explanation:
(I originally posted this as a comment because Brainly was not allowing me to answer).
-8 is a negative number, which means many operations don't work the same on it. Subtracting a positive number from a negative number will give you the same result as adding the two positive numbers (in this case, 8 + 9), though the answer will also be negative. Hope this helps!

Answer: y is a false statement
Step-by-step explanation: put all the y terms on one side and all the constants on the other. i'm going to move all the y terms to the right and the constants to the left. on the left we have a -5 leftover and on the right it would be 7y-y-6y. if you add those terms together, you're left with -5=0 which is not possible. y is a false statement
