Answer:
If I'm correct the slop appears to be 3x or (3/1)x
Step-by-step explanation:
First of all we need to remember rise/run (y/x) and that we begin calculating the slope by starting at the first point we are given on the graph
This linear equation goes up or "rises" up 3 on the y-axis till it meets a specific x-value giving us our rise of 3. Next we check on our "run" over the x-axis, which we find to be 1. The rise will represent our numerator and the run will represent our denominator. Thus we have 3/1 or a slope of 3.
You can also calculate this by picking the first given point on our line and finding its x and y coordinates on the plane. Then we can locate another point on the line and find its x and y coordinates as well. We take these two points' coordinates and divide using the point-slope formula. (x1,y1)/(x2,y2). I can't clearly see the points on your graph otherwise I'd tell you how to complete the point-slope formula in this example. However, we can eyeball it by using the first method (which isn't always accurate so I recommend using the point-slope formula when you can).
Answer:
184
Step-by-step explanation:
V=lwh
(4)(5)(2) = 40
(7)(4)(3) = 84
(2)(5)(4) = 60
40 + 84 + 60 = 184
A / [ pi r^2 ]<span> = θ / [ 2pi ] </span> [ multiply both sides by pi r^2 ]
A = [ θ / 2 ] r^2 = <span> (1/2)r^2 θ</span>
If 2x+y=5, then y=5-2x, so he substituted 5-2x correctly.
x+4x=5x, so he combined like terms correctly.
If 5x-10=10, then 5x=10+10 -> 5x=20, so he subtracted 10 from the right side instead of adding 10 to the right side.
The answer is C.
Here's the correct solution:
