Answer:
Step-by-step explanation:
Given the equation of a line expressed as y = 3x-1, we are to find y = f(x) for the following values of x in the table.
If y = 3x-1, then f(x) = 3
When x = -1
f(-1) = 3(-1)-1
f(-1) = -3-1
f(-1) = -4
<em>Hence when x = -1, f(x) = -4</em>
<em></em>
When x = 0
f(0) = 3(0)-1
f(0) = 0-1
f(0) = -1
<em>Hence when x = 0, f(x) = -1</em>
<em></em>
When x = 2
f(2) = 3(2)-1
f(2) = 6-1
f(2) = 5
<em>Hence when x = 2, f(x) = 5</em>
Given:
m/n-3(m+n)
m=-10 and n=-2
Solving:
-10/-2-3(-10-2) Since m=-10 and n=-2, we substitute them in for the values since they have an equal relationship.
Now, follow Orders of Operations: PEMDAS
-10/-2-3(-12) Simplify parentheses (P)
There are no Exponents (E)
Multiplication (M) and Division (D) are =, so we do whatever operation comes from the left to right.
-10/-2=5 Division comes first on the left.
therefore:
5-3(-12)
-3(12)=-36, Multiplication is last on the right.
therefore:
5-36
5-36=-31 After M/D, we do Addition and Subtraction, which are also =, so we do them left to right.
Therefore -10/-2-3(-10-2)=-31
Answer:
25x-4
Step-by-step explanation:
5x^2=5x multiplied by 5x= 25x
25x-4 is simpliest form and evaluated
Have a great day, and good luck!
Answer:
y=
-5/2x
-25/2
Honestly I don't know if this is right so sorry if its wrong.
