Answer:
34.1546, 34.248, 39.637, 44.3421, 44.351
Step-by-step explanation:
Hello :
<span>y=-3x- 2 ...(1)
5x+3y=15...(2)
subsct in (2) : 5x +3(-3x-2) =15
5x-9x-6 = 15
-4x = 21
x = -21/4
y = -3(-21/4)-2 .....calculate </span>
Answer:
x = 21
Step-by-step explanation:
-7 ( x + 1 ) - 3 = -8x + 11
-7x - 7 - 3 = -8x + 11
x = 7 + 3 + 11
x = 21
Answer:
The work done in stretching the spring is 8 lb.ft
Step-by-step explanation:
Given;
Applied force, F = 192 lb
extension of the spring, x = 3 ft
Determine the spring constant from the applied force and extension;

When the spring is stretched 6 inches beyond its natural length, the work done is calculated as follows;
x = 6 inches = 0.5 ft

Therefore, the work done in stretching the spring is 8 lb.ft
265/99, is what I think but I’m not sure
