Answer:
f(x) = 3x
Step-by-step explanation:
The equation of a line passing through the origin is
y = mx ( m is the slope )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (1, 3)
m = 
= 3 , then
y = 3x ← is the equation of the graphed line
Answer:
$7
Step-by-step explanation:
1. 1/5 = 2/10
2. 2/10 = 20%
3. 20% = 0.2
4. 35 x 0.2 = 7
Answer:
-15
Step-by-step explanation:
(-3)^2 - 3(-3)(-2) + 2(-3)
Answer:
Do you mean which equation should the 5x+10=15 be multiplied to?
it would be -2
Step-by-step explanation:
This is because 5 times -2 is -10
and so when you add the (now) x value of the first equation to the x value of the second equation, it gets 0
which makes it eliminated!
-10x+10x=0
The answer is C.) x = 7; x = -6
