lol ok so
7*something or you can make it into a variable x=35
7*x=35
/7 /7
x=5.
The slope-intercept form of x - y = 7 is y = x - 7. The slope of that line is 1. That means the slope of the line that also goes through (1, 0) is also 1. If you use the point-slope formula, the answer you will receive is y = x - 1.
Answer:
p ≈ 19.19 %
Step-by-step explanation:
198 - p×198/100 = 160
19800 - 198p = 16000
19800 - 16000 = 198p
3800 = 198p
p = 19.19 %
Solve for x:
x^3 + x^2 + 4 x + 4 = 0
The left hand side factors into a product with two terms:
(x + 1) (x^2 + 4) = 0
Split into two equations:
x + 1 = 0 or x^2 + 4 = 0
Subtract 1 from both sides:
x = -1 or x^2 + 4 = 0
Subtract 4 from both sides:
x = -1 or x^2 = -4
Take the square root of both sides:
Answer: x = -1 or x = 2 i or x = -2 i
