Instructions: Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s).Consider the functions f(x)=x^2+9x and g(x)=1/x.
f(g(-1)) is
g(f(1/2)) is
Answers
Answer:
-8
2/19
Step-by-step explanation:
We must substitute x=-1 into g(x) and then the answer of g(x) we must substiute as x into f(x). Similarly we must substitute x=1/2 into f(x) and the answer as x into g(x):
1. x=-1 into g(x)
substitute x=-1 into f(x)
2. x=1/2 into f(x)
substitute x=19/2 into g(x)

The required solution of the simultaneous equation is x = -1 and y = -1.
Given that,
To solve the given simultaneous equation,
5x+6y= −11
5x = 2y −3
What are simultaneous linear equations?
Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.
here,
5x = 2y −3 - - - - - (1)
5x+6y= −11
By substitution, from equation 1
2y - 3 + 6y = -11
8y = -8
y = -1
Now,
5x = -2 - 3
x = -1
Thus, The required solution of the simultaneous equation is x = -1 and y = -1.

Answer: For number 8, x=6. For number 9, x=7. For number 10, x=15
Step-by-step explanation:
#8:
Angle 16x-6 corresponds to the 90 degree angle. Therefore, they are equal.
16x-6=90
Add six: 16x=96
Divide by 16: x=6
#9
Angle 12x-4 and angle 10x+10 correspond. Therefore, they are equal.
12x-4=10x+10
Subtract 10x: 2x-4=10
Add four: 2x=14
Divide by 2: x=7
#10
Angles 7x and 5x+30 are alternate exterior angles. Therefore, they are equal.
7x=5x+30
Subtract 5x: 2x=30
Divide by 2: x=15
