Answer:
The answer is: 
Step-by-step explanation:
We are given:
and 
We need to find
.
Simply divide
and
.
Which equates to:

This cannot be simplified further, so it is the answer.
7x+4=88
7x=84
x=12
7x-12=7*(12)-2=82
angle 1=180-82=98
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
1)
-----> For the interval (-∞,-1)
Note The value of x=-1 is a open circle ( is not included)
This is a vertical parabola open upward
The vertex is a minimum
The vertex is the point (-2,0)
2)
----> For the interval [-1,1]
Note The value of x=-1 and x=1 are closed circle ( both values are included)
This is an absolute function open upward
The vertex is the point (0,1)
3)
-----> For the interval (1,∞)
Note The value of x=1 is a open circle ( is not included)
The value of f(x) is negative for all values of x
therefore
The graph in the attached figure
Yes it is in its simplest form
1. D. because the angels of KRC and CRH added together is 180 degrees. Which equals a straight line.
2. Answer is A . BHR is equal to NHD, so it is 8x. But we need to find x first.
The right angle in the picture is 8x + (9x +5)
90 =8x + 9x +5
90 = 17x + 5
85 = 17 x
5 = x.
X is 5 so 8x is 40.
3. B. The opposite angles are equal to each other. and the sum of two angles side by side equal 180.
6x - 82 = 3x +23
group like terms
6x - 3x = 23 + 82
3x = 105
x = 35.
Answer is B
4.B. a complement angle added together will get you 90.
90 - 41 = 49
Answer is B
