Step-by-Step explanation:
Step 1: Define
8(x + 5) + 4 = 60
Step 2: Solve for a
1. Distribute 8: 8x + 40 + 4 = 60
2. Combine like terms: 8x + 44 = 60
3. Isolate x term: 8x = 16
4. Isolate x: x = 2
Step 3: Check
Plug in x to verify it’s a solution.
1. Substitute: 8(2 + 5) + 4 = 60
2. Add: 8(7) + 4 = 60
3. Multiply: 56 + 4 = 60
4. Add: 60 = 60
3.5 because you take 7 and divide by 2 since you have to multiply you base times width to get area I think I might be wrong
Answer:
Is that the whole Question??
Step-by-step explanation:
Here we are given the specific equation of:
amount of eroded soil = 0.4 + 1.3 x
where x is the flow rate
A linear equation has a general formula in the form of:
y = m x + b
where m is the slope and b is the y intercept of the equation
If we compare this with our specific equation, we can see that the slope and y intercept are both positive with values:
m = 0.4
b = 1.3
Therefore this only means that as the flow rate increases, the amount of eroded soil also increases.
Hence the correlation must be positive but we cannot solve for the exact value since we need the data for x and y.
Answer:
positive, but we cannot say what the exact value is
