Substitute the value for y as 450
450=-5x+1
Solve for x
450-1=-5x
449=-5x
89.8=-x
x=-89.8
Answer:
x = 290
Step-by-step explanation:
The x- intercept is the point on the x- axis where the line crosses.
substitute y = 0 into the equation and solve for x
- 5x + 1450 = 0 ( subtract 1450 from both sides )
- 5x = - 1450 ( divide both sides by - 5 )
x = 290 ← x- intercept
line crosses x- axis at (290, 0)
1. x= -5
2. x= 12
3. x= 49
4. r= or 2.792
5. s= 6
-15
x-1/2(x+5)=-10
x-1/2x-5/2=-10
2/2x-1/2x-5/2=-10
1/2x-5/2=-10
1/2x=-10+5/2
1/2x=-20/2+5/2
1/2x=-15/2
x=(-15/2)/(1/2)
x=(-15/2)(2/1)
x=-15/1
x=-15
