Answer: x = -1/2
4x² + 4x + 1 = 0
⇔ (2x + 1)² = 0
⇒ 2x + 1 = 0
⇔ x = -1/2
Step-by-step explanation:
No matter where the negative sign is, the product will always be negative, so is the number itself.
13.2(-8.1)=-106.92
twice of that would be -213.84.
first do the multiplying, then the adding(the adding of negative numbers, so it would be basically subtracting).
y = 8
x = 575
We want to solve for b in the slope-intercept form y = mx + b.
To complete this problem, we need the value of m, the slope. If you know m, then just plug into y = mx + b this way:
8 = 575m + b
The answer is D
