Answer:
r= 6p + 20
Step-by-step explanation:
given:
r= 3n + 20
also given that n = 2p
substituting n=2p into the above equation
r= 3n + 20
r= 3(2p) + 20
r= 6p + 20
Answer:
y = -2x - 1 ; slope = -2, y-intercept = (0, -1)
Step-by-step explanation:
to get the slope and y intercept, you need to put the equation into slope-intercept form: y = mx + b
the term mx is the slope of the line, and b is the y-intercept
to do this, you need to solve for y, so get y by itself by subtracting 8x from the left side
8x + 4y = -4
-8x. -8x
4y = -8x - 4
divide both sides by 4 to get y alone
4y/4 = y
-8x/4 = -2x
-4/4 = -1
y = -2x - 1 is the final equation
the slope of the line is -2 (also can be said as -2/1), and the line intercepts the y-axis at (0,-1)
Answer:
183.17 cm cubed
Step-by-step explanation:
You would multiply 1/3 times pi times the radius squared times the height
so it would look like 1/3 * 3.14 * 5 squared * 7
5 squared is 25 and 25 times 7 is 175
Then you multiply 175 by 3.14 giving you 549.5
then you divide 549.5 by 3 resulting in 183.1667
then you round to 183.17 cm cubed
