U didn't mess up....
V = pi * r^2 * h....divide both sides by (pi)r^2
V / (pi)r^2 = h
Answer:
-8x^2-10x+12
Step-by-step explanation:
first set up the problem:
(-3x^2-7x+5)-(5x^2+3x-7)
Since you are subtracting you need to distribute the (-) sign:
(-3x^2‐7x+5)(-5x^2-3x+7)
Now just combine like terms
-3x^2+(-5x^2= -8x^2
(-7x+(-3x= -10x
5+7= 12
set answer in standard form:
-8x^2-10x+12
(3,4)(5,16)
slope = (16 - 4) / (5 - 3) = 12/2 = 6
y = mx + b
slope(m) = 6
use either of ur points (3,4)...x = 3 and y = 4
sub and find b, the y int
4 = 6(3) + b
4 = 18 + b
4 - 18 = b
-14 = b
so ur equation is : y = 6x - 14
It should be letter D positive 1
A because y is larger than x by 2.
x + y = 44
y = x + 2
Substitute eqn 2 into eqn 1
x + x + 2 = 44
2x = 42
x = 21
Thus, the smaller number is 21.
