<span>The answer is that x = 21/9.
Start with the original: 4(2x - 1) - 7 = 4 - x + 6
Now distribute the 4:</span> <span> 8x - 4 - 7 = 4 - x + 6.
Now combine the like terms. 8x - 11 = -x + 10.
Now add x to both sides. 9x - 11 = 10.
Now add 11 to both sides. 9x = 21.
And divide by 9 on both side. x = 21/9. </span>
Increasing: positive slope
Decreasing: negative slope
Constant: zero slope.
Hope this helps pls brainliest
I can't see the instructions, so I assume you're solving for the variable to the right.
(a)
A = pi*r(l+L), first divide both sides pi*r
A/(pi*r) = l + L, next subtract l from both sides
L = A/(pi*r) - l
(b)
V = pi*r^2*h, first isolate the variable r by dividing both sides by pi*h
V/(pi*h) = r^2, next take the inverse operation of square, which is the square root
r = sqrt root [ V/(pi*h)], assume r is a positive number only, so you do not need to consider the - square root option
(d)
t = 2*pi*sqrt (L/g), first divide both sides by 2*pi to isolate the radical
t/(2*pi) = sqrt (L/g), next square both sides to remove the radical sign over L
[t/(2*pi)]^2 = L/g, last multiply both sides by g
L = g*[t/(2*pi)]^2
(e) (actually it should say KE for kinetic energy)
E = (1/2)mv^2, multiply both sides by 2 and divide both sides by m
2*E/m = v^2, next take the inverse operation of square, square root of both sides
v = sqrt [2*E/m], again assume v is a positive quantity, although velocity is a vector quantity and should indicate both magnitude and direction
32, i believe is the answer
Set like terms on each side by adding six to the first side and subtracting 1/2x from the first side. this gives you 9<1.5x. divide both sides by 1.5 to get 66. the answer is 4) x>6
