the x intercept is where the line crosses the x axis or where y=0
the y intercept is where the line crosses the y axis or where x=0
x intercept:
set y=0 and solve for x
2y+1=3x+5
2(0)+1=3x+5
1=3x+5
-4=3x
x=-4/3
x intercept is at (-4/3,0)
y intercept:
set x=0 and solve for y
2y+1=3x+5
2y+1=3(0)+5
2y+1=5
2y=4
y=2
y intercept is at (0,2)
Step-by-step explanation:
5) 2 lines are perpendicular
slope of line 1 =3
slope of line 2= _1/3
6)perpendicular
Answer: Yes
Step-by-step explanation: Because a integer is -45.58
Answer:
Step-by-step explanation:
Let
x ----> the number of minutes
y ----> the total charge in dollars
we know that
For x>700 min
so
For y=48.10
substitute
Multiply by 100 both sides
----> equation without decimals
solve for x
To find out the total minutes we need to sum
Answer:
B. tan (-180°) = 0
Step-by-step explanation:
Tangent is the ratio of opposite to adjacent to an angle
From the unit circle; the opposite to our angle -180° is 0
The adjacent along the x-axis is 1
Therefore;
Tan (-180°) = 0/1
= 0
Therefore; Tan (-180°) is 0
