Answer:
The domain is the input values on the x-axis and range is input values on the y-axis
Step-by-step explanation:
Basically, domain is the horizontal values and range is the vertical ones.
You have two choices: the easiest is to turn every fraction to its numerical equivalent:
Now, remember that negative numbers are ordered in the opposite way with respect to positive numbers (for example, 4 is larger than 2, but -4 is smaller than -2). So, the order is
Alternatively, you can convert all the fractions so that they have the same denominator. In this case, you will need the least common multiple of 10, 7, 4, 5 and 3, which is 420. Once you do so, you can easily order the fractions using numerators only.
Answer:
x= 7
y=9
z=90
Step-by-step explanation:
8x = (9x-7)
8x = 9x-7
8x - 9x= -7
-x= -7
<em>(multiply -1 to each side to make it positive)</em>
x= 7
(5y-11)+(9x-7)=90
5y-11+9(7)-7=90
5y-11+63-7=90
5y+63-18=90
5y+45=90
5y=90-45
5y=45
y=45÷5
y=9
(5y-11)+8x+z=180
5y-11+8x+z=180
5(9)-11+8(7)+z=180
45-11+56+z=180
34+56+z=180
90+z=180
z=180-90
z=90
Answer:
We know that our triangle has one side along the line:
y = (1/4)*x
And other side along the line:
y = -(1/4)*x.
Now, we want to find the vertex.
And we know that the vertex is the point where the two sides conect, so the vertex must be a common point of both lines.
Then we have:
y = (1/4)*x = -(1/4)*x
x = -x
The only solution to that equation is x = 0.
now we evaluate our lines in x = 0 and get:
y = (1/4)*0 = 0
y = -(1/4)*0 = 0
Then the lines intersect in the point (0, 0)
Then the vertex must be in the point (0, 0)
