Step-by-step explanation:
thirty six point five(36.5)
Solve for x over the real numbers:
x^2 - 4 x = 5
Subtract 5 from both sides:
x^2 - 4 x - 5 = 0
x = (4 ± sqrt((-4)^2 - 4 (-5)))/2 = (4 ± sqrt(16 + 20))/2 = (4 ± sqrt(36))/2:
x = (4 + sqrt(36))/2 or x = (4 - sqrt(36))/2
sqrt(36) = sqrt(4×9) = sqrt(2^2×3^2) = 2×3 = 6:
x = (4 + 6)/2 or x = (4 - 6)/2
(4 + 6)/2 = 10/2 = 5:
x = 5 or x = (4 - 6)/2
(4 - 6)/2 = -2/2 = -1:
Answer: x = 5 or x = -1
Answer:
y = -2x+3
Step-by-step explanation:
This is assuming you want the answer in slope-intercept (y = mx+b)
You need to know:
y = The line
m = The slope
b = The y-intercept
Step 1, replace the slope (m):
y = -2x+b
Step 2, replace the y-intercept (b):
y = -2x+3
Conclusion to 'complete the equation of the line whose slope is -2 and y intercept is (0,3)': y = -2x+3
22 or 20 is the right answer 22.2222222 round it
Answer:
1/2n - 11 = -25
Hope this helps you! Have a good night!
Also, n = -28
1/2n - 11 = -25
1/2n - 11 + 11 = -25 + 11
1/2n = -14
1/2n / 1/2 = -14 / 1/2
n = -28
Check:
1/2(-28) - 11 = -25
-14 - 11 = -25
-25 = -25
