that would give you the miles in one hour.
Hope that helps:)
Answer:
x=8.499
y=0.167
Step-by-step explanation:
the equation says:x^2-9y^2=72....(1)
x+3y=9.......(2)
divide (2) from (1),it becomes:
x-3y=8
making x subject of formula,
x=8+3y....(3)
submitting (3) into (1),it becomes
(8+3y)^2-9y^2=72
64+48y=72
48y=72-64=8
y=8/48=0.167......(4)
submitting (4) into (2),it becomes
x+3(0.167)=9
x+0.501=9
x=9-0.501
x=8.499
Answer:
see below
Step-by-step explanation:
5x - 6y = 21
Let x = 0 and solve for y to find the y intercept
-6y = 21
Divide by -6
y = 21/-6 = -7/2
The y intercept is (0,-7/2)
5x - 6y = 21
Let y = 0 and solve for x to find the x intercept
5x = 21
Divide by 5
y = 21/5 = 21/5
The x intercept is (21/5,0)
