Step-by-step explanation:

z=√9.3 +8.2^2

z=70.28959013

e=1/2 2.1(6.3)^2

e=41.6745

p=8+5/4

p=13/4

What I came up with for the last three are:

q=r/4-7p/4

f=e^2+12e+36

y=x/z+7/z

Hopefully these are all correct. :)

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

f(x)=2/3x-8, which give g(x) the greatest value.
