Answer:
Step-by-step explanation:
To find the slope, you want to use the formula .
Now we know the slope is .
Solve for x (4/y) + (3/x) = 8 (6/y) + (5/x) = 13
1 answer:
Answer:
0.5
Step-by-step explanation:
Given data
Now,
4x+3y=8xy......(i)
6x+5y=13xy.......(ii)
Multiply by 5 in equation (i) and by 3 in equation (ii)
20x+15y=40xy.....(iii)
18x+15y=39xy.....(iV)
Solving above equation (iii) and (iv)
2x=xy
y=2
Now, putting the y=2 in equation (i)
4x+3(2)=8x(2)
4x+6=16x
6=12x
x=0.5
Value of x=0.5

For this problem you must do Pythagorean theorem:
In this example 10ft is c and 7ft is a (or it could be b, and you'll be solving for a instead of b. It's the same thing, since a and b are both legs)
Plug what you know into the equation:
49 +b^{2} = 100
Bring 49 to the right side by subtracting it:
b^{2} = 51
Now you still must isolate b. The opposite of squaring is taking the square root so take the square root of both sides to cancel it from the left side:
b = 7.1414
b ≈ 7 ft
