Answer:
<em>y-9=0(x-6)</em>
<em>Or, equivalently: y=9</em>
<em>This represents a horizontal line</em>
Step-by-step explanation:
<em>Equation of the line</em>
The point-slope form of the equation of a line is:

Where m is the slope and (h,k) is a point through which the line passes.
Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

The points are (6,9) and (7,9). These points dfine a horizontal line, as we'll see later.
The slope is:

m=0
Now compute the equation in point-slope form:
y-9=0(x-6)
Solving for y:
y=9
This represents a horizontal line
Answer: 42
Step-by-step explanation:
First you have to subtract 450 from 6750 to get 6300
Second you have to figure out how many tax returns you have to make by dividing 6300 by 14 to get 450
Third you have to do 6300 / 42 to get 150 so if you times 150x 42 equals 6300.
1.6666666666666... because 8 divided by 12=1.6666666666...
Answer:
20
Step-by-step explanation:
An angle bisector cuts an angle into two equal parts. So m∠ACE = m∠ECB.
m∠ACE = m∠ECB
2x − 15 = x + 5
x = 20
Answer:
Step-by-step explanation:
3x2 - y2 = 9.........(1)
x2 + 2y2 = 38......(2)
Let x^2 = a and y^2 = b
:- the two equations becomes
3a - b = 9..........(3)
a + 2b = 38.......(4)
Multiplying (4) by 3
3a + 6b = 114........(5)
Substracting (3) from (5)
3a - 3a + 6b - (-b) = 114 - 9
6b +b = 105
7b = 105
b = 105/7
b = 15
And 3a - b = 9 putting b = 15
3a - 15 = 9
3a = 15+9
3a = 24
a = 24/3
a = 8
And
x^2 = a
x^2 = 8
x = √8
x = √(4×2)
x = 2√2
Also y^2 = b
y^2 = 15
y = √15
