Answer:
you need to attach graphs so we can see & help lol ; ]
Step-by-step explanation:
Let janes age be x
let Harvey's age be 3x (as three times old as jane)
x+3x=48
4x=48
x=48/4
there fore x= 12
janes age= 12
Harvey's age = 3x
=3*12
=36
To find the x-intercept, let y = 0, and solve for x.
5y - 3x = 15
Let y = 0.
5(0) - 3x = 15
-3x = 15
x = -5
The x-intercept is -5.
To find the y-intercept, let x = 0, and solve for y.
5y - 3x = 15
Let x = 0.
5y - 3(0) = 15
5y - 0 = 15
5y = 15
y = 3
The y-intercept is 3.
Answer:
C. X-int -5
Y-int 3
Answer:
0.05
Step-by-step explanation:
The formula for slope is rise/run.
So, in this case it would be 2.9ft/58ft = 0.05
