Divide the estimated number by the exact number and multiple by 100
Answer:
y = 2x - 7
Step-by-step explanation:
Parallel lines have the same slope, so the line will also have a slope of 2
Plug in the slope and given point into y = mx + b to solve for b:
y = mx + b
3 = 2(5) + b
3 = 10 + b
-7 = b
Then, plug in the slope and b into y = mx + b
y = 2x - 7 is the equation of the line
Answer:
equation of line:
y = mx + b....equation(1)
slope = m = -1/4
y-intercept = b =?
put point(12,5) and slope (-1/4) in equation(1)
5 = (-1/4)(12) + b
5 = -12/4 +b
5 = -3 + b
5 + 3 = b
b = 8
putting values of b and m in equation(1)
y = (-1/4)x + 8
Step-by-step explanation:
Answer:
B.
Step-by-step explanation:
Step 1: Cross-multiply
x² + 2x = 4x²
Step 2: Isolate <em>x</em>'s
2x = 3x²
0 = 3x² - 2x
Step 3: Factor
x(3x - 2) = 0
Step 4: Find roots
x = 0, x = 2/3
Step 5: Double check answers.
When you do so, you should see that only x = 0 works. And we have our answer!
