8.5 x 250,000 = 2,125,000
2,125,000 x .00001 = 21.25km
1cm = .00001km

Answer:
now the answer sorry for that i am in 5th grade so i dont know sorry
Step-by-step explanation:
Answer:
Slope = 4/3x; y-intercept = -1
Step-by-step explanation:
y + 1 = 4/3x
You have to write this equation in slope-intercept form (solve for y) if you want to find the slope and y-intercept
y + 1 = 4/3x
Subtract one from both sides
y + 1 - 1 = 4/3x - 1
y = 4/3x - 1
Now that we have the equation, you can now find the slope and y-intercept
y = mx + b; m is the slope and b is the y-intercept
So for y = 4/3x - 1, the slope is 4/3x and the y-intercept is -1
Answer:
x = 0
Step-by-step explanation:
Step 1: Write equation
3x - x + 4 = 4(2x + 1)
Step 2: Solve for <em>x</em>
- Distribute: 3x - x + 4 = 8x + 4
- Combine like terms: 2x + 4 = 8x + 4
- Subtract 2x on both sides: 4 = 6x + 4
- Subtract 4 on both sides: 0 = 6x
- Divide both sides by 6: x = 0
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
3(0) - 0 + 4 = 4(2(0) + 1)
4 = 4(1)
4 = 4
