Answer:
Step-by-step explanation:
The point-slope form of an equation of a line:
m - slope
Parallel lines have the same slope.
We have the equation in the slope-intercept form (y = mx + b)
Put to the point-slope equation value of the slope and the coordinates of the point (4, -5):
You first work out the mean then for each number subtract the mean and square the result then work out the mean of those squared differences and take the square rot of that and you're done :)
So, let’s find out the numbers needed to form the ratio. The length of the swimming pool is 50 ft long. We need to find the perimeter. 2(50+35)
2*85
170.
So, the perimeter is 170 ft. Now we need to form the ratio. Length is first, then the perimeter.
50:170 is your ratio, but we can simplify it to 5:17. Hope this helped!
Answer:
The standard form of a quadratic is y = ax^2 + bx + c.
- In this equation, the formula for the axis of symmetry is x =
. - You know that the center will always be along that line, and you've got the x-coordinate already, so just plug that in and get the y-coordinate out for the center.
The vertex form of a quadratic is also helpful, y = a(x-h)^2 + k.
- In this equation, the formula for the center is (h, k), and the axis of symmetry is x = h! That's even easier!
<span>(-2, y1), (6, 7) Slope = 1/2
slope = (y2-y1)/(x2-x1)
1/2 = (7 - y1) / (6 - -2)
1/2 = (7-y1) / 8
7-y1 = 8/2
7-y1 = 4
y1 = 7 - 4
y1 = 3
Answer: </span><span>(-2, 3), (6, 7) with Slope = 1/2
</span>proof:
slope = (y2-y1)/(x2-x1)
slope = (7 - 3) / (6 - -2)
slope = 4/8
slope = 1/2
