Answer:
(x, y) = (-1, 6)
Step-by-step explanation:
y = 2x + 8
y = 5 - x
Substituting the second equation into the first equation, we get:
5 - x = 2x + 8
5 = 3x + 8
-3 = 3x
x = -1.
So, y = 5 - (-1).
Simplifying, we get:
y = 6.
R = (2s - 6t + 5)/2
2R = 2s - 6t + 5
2s = 2R + 6t - 5
s = (2R + 6t - 5)/2
2x 10 = 4x - 1
-2x - 10 = -1
-2x = 9
x = -9/2
y = 2(-9/2) -10
y = -9 - 10
y= -19
Answer:
The change in x = Δx = -1
Step-by-step explanation:
Given the ordered pairs
Here,
Change in x can be calculated by subtracting the value of x₁ = 6 from x₂ = 5.
Change in x = Δx = x₂ - x₁ = 5 - 6 = -1
Thus, the change in x = Δx = -1
The diameter is given which is 13.5feet and radius is half of diameter. Therefore radius = 6.75 feet.
