310 miles ÷ 5 hours = 62 miles per hour
403 miles ÷ 62 = 6.5 hours
Answer:
y =
x + 
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 )
Rearrange 10x - 20y = - 3 into this form
Subtract 10x from both sides
- 20y = - 10x - 3 ( divide all terms by - 20 )
y =
x -
, that is
y =
x +
← in slope- intercept form
Answer:
Step-by-step explanation:
3 1/5= 3 2/10
4 1/2= 4 5/10
3 2/10+ 4 5/10= 7 7/10
Answer:
System of Linear Equations entered :
[1] 4x - 3y = 15
[2] 2x + 2y = 4
Step-by-step explanation:
// Solve equation [2] for the variable y
[2] 2y = -2x + 4
[2] y = -x + 2
// Plug this in for variable y in equation [1]
[1] 4x - 3•(-x +2) = 15
[1] 7x = 21
// Solve equation [1] for the variable x
[1] 7x = 21
[1] x = 3
// By now we know this much :
x = 3
y = -x+2
// Use the x value to solve for y
y = -(3)+2 = -1
Solution :
{x,y} = {3,-1}
