Answer:
y = x + 2
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3x + y = 4 ( subtract 3x from both sides )
y = - 3x + 4 ← in slope- intercept form
with slope m = - 3
Given a line with slope m then the slope of a line perpendicular to it is
= - = - =
Given c = 2 , then
y = x + 2 ← equation of perpendicular line
Answer:
y : x: = 5 : 4
Step-by-step explanation:
x to y = 4 to 5
Rewrite;
x:y = 4:5
Remember, a ratio is another way of representing a fraction, hence one can do the same operations that one could do with a fraction. Therefore, one can take the cross products of a ratio;
x : y= 4 : 5
5x = 4y
Inverse operations;
5x = 4y
x = y
Now substitute this into the equation y:x
y : y
Rewrite as a fraction;
Simplify;
Rewrite as a ratio;
y : x = 5 : 4
You gotta pick number (Miles) that give you higher figure for 0.15 and lower figure 0.10 so that the actual answer comes same after adding them with per day charges.
Let's pick 100 miles for A and B,
A, 0.10x 100 = $10
= ($35 + $10)
=$45
B, 0.15 x 100 = $15
= ($25 + $15)
=$40
Well, it ain't giving us same charge, so we should go higher miles
Let's take 200 miles this time.
A, 0.10x 200 = $20
= ($35 + $20)
=$55
B, 0.15 x 200 = $30
= ($25 + $30)
=$55
Answer: after 200 miles.
I think the second choice has the correct domain and ranges
Answer:
The vertices of the triangle A'B'C' are , and , respectively.
Step-by-step explanation:
Vectorially speaking, the reflection of a point over the x-axis is defined by the following expression:
(1)
Where:
- Original point.
- Reflected point.
If we know that , and , then the vertices of the triangle A'B'C':
, ,
The vertices of the triangle A'B'C' are , and , respectively.
