Answer:
- y -8 = 8/5(x +2)
- y = 8/5x +56/5
- 8x -5y = -56
Step-by-step explanation:
Since you're given a point and slope, it is convenient to start with that form.
<u>Point-slope form</u>
y -k = m(x -h) . . . . . line with slope m through point (h, k)
y -8 = 8/5(x +2) . . . point-slope equation
__
<u>Slope-intercept form</u>
y = mx + b . . . . . line with slope m and y-intercept b
The above equation can be rearranged to this form.
y = 8/5x +16/5 +8
y = 8/5x +56/5 . . . . . slope-intercept form
__
<u>Standard form</u>
ax +by = c
Multiplying by 5 and subtracting the y-term gives the general form equation ...
5y = 8x +56
8x -5y +56 = 0
8x -5y = -56 . . . . . . add -56 to put into standard form
Answer:
1: equivalent
2: equivalent
3: not equivalent
Step-by-step explanation:
for 1 & 2, you just switch the terms, but for 3, the 6z is not negative in the first expression, but it is in the second.
The answer to this is A. 650. You find the surface area of the two cubes, then the rectangular prism, then you add them together.<span />
4 3/4 =19/4=57/12
57/12 is larger than 38/12
So, any set of three angles that add up to 180 degrees can form a triangle
