1) x^2 + 8x + 16 = (x+4)^2
Answer: C. 16
2) x^2 + 4x + 4 = (x+2)^2
Answer: B. 4
Answer:
y = (-1/4)x + 9/4
Step-by-step explanation:
2y = 8x - 6
So, y = 4x - 3 (Slope = 4)
Slope of perpendicular line = -1/4
Equation of line: y-3 = (-1/4)(x-(-3))
y-3 = (-1/4)x - 3/4
y = (-1/4)x + 9/4
Answer:
D) 3 X 10⁷
Step-by-step explanation:
<u>Estimated days:</u>
- Jan 2000 to June 2001 = 1.5 years = 365*1.5 days ≈ 548 days
- 1 day = 24 hours = 24*60 minutes = 24*60*60 seconds =
- 548 days = 548 * 86400 seconds =
Best estimate is D) 3 X 10⁷
You keep the denominator the same so it's D) 7/8
Answer:
the slope is 4
Step-by-step explanation:
-you have to solve for y;keep y by itself on one side of the equation
-you start by subtracting 4x on both sides(to get rid of it on the left side of the equation). you end up with -y= -4x+6
-y must be positive when it is alone, so to make it a positive, you have to divide both sides of the equation by -1. you end up with y= 4x-6
-so now that we have y by itself and positive, we can identify the slope. (the slope will always be what is right next to x, in this case it is 4). so the slope is 4
