Answer:
Step-by-step explanation:
<u>The line with points (1,2) and (-1,-8). Work out its equation.</u>
<u>The slope is:</u>
- m = (-8 - 2)/(-1 - 1) = -10/-2 = 5
<u>To find the y intercept, substitute x and y-xoordinates of point (1,2):</u>
- 2 = 5(1) + b
- b = 2 - 5
- b = -3
<u>The line is:</u>
<u>Point (x, 17), substitute y-coordinate and solve for x</u>
- 17 = 5x - 3
- 5x = 17 + 3
- 5x = 20
- x = 20/5
- x = 4
Answer:
que?
Step-by-step explanation:
we have chicken broth in cylindrical can.
we have given the height radius of cylindrical can.
h=10cm r=10 cm .
and she have 6cm broth height in the tin that means she had used 4 cm of height of broth .
now we need to find volume of two cylinder with h=10 cm and 6cm
and we need to find the difference between the volumes .
volume1=
volume 2=
volume used =volume 1-volume2=3140-1884=1256cm^3 is used
Assuming yo mean
k²-4k-21
factor by doing
what 2 numbers multipily to get -21 and add to get -4?
-7 and 3
(k-7)(k+3) is factored
