Ok rmemeber
√(a/b)=(√a)/(√b)
and
√ab=(√a)(√b)
and
(a^m)/(a^n)=a^(m-n)
so

ignore 11 for now, we will get to that at end

\sqrt{ \frac{49a^{5}}{4a^{3}}}=
\frac{\sqrt{49a^{5})}{\sqrt{4a^{3}}}=
\frac{(\sqrt{49})(\sqrt{a^{5}})}{(\sqrt{4)(\sqrt{a^{3}}}=
\frac{(7)(a^{2} \sqrt{a}) }{(2)(a \sqrt{a}) }=
\frac{7a^{2} \sqrt{a} }{2a \sqrt{a} }=
\frac{7a}{2}

IM Not too sure on this. can someone please help me out?
DENIUS [597]
All it is asking is to plug the given x values into the equation (which are 0, 2, 4) and see what you get for y.
4y - 2x =16

4y - 2 (0) = 16
4y = 16
y = 4

4y - 2 (2) = 16
4y - 4 = 16
4y = 20
y = 5

4y - 2 (4) = 16
4y - 8 = 16
4y = 24
y = 6

so D

Simplify the expression 10-4x(6+5-1) divided by 8+7
Eddi Din [679]
Simple,

writing out the problem...

\frac{10-4x(6+5-1)}{15}

Simplify it...

-4x(6+5-1)

-4x(11-1)

-4x(10)

-40x

Making it look like...

\frac{10-40x}{15}

Cancel out the common factors...

Thus making the answer:

- \frac{2(4x-1)}{3}.
