Answer:

2/5

Step-by-step explanation:

when adding a positive to a negative, you can reverse the order so that you can remove the addition sign:

so instead of -4/5 + 6/5

you can make it 6/5 - 4/5 which equals 2/5 or .4

Factor. 2y^2 - 7y + 6

yuradex [85]

2y^2-7y+6= 2y^2-4y-3y+6
=2y(y-2)-3(y-2)
=(2y-3)(y-2)
Therefore
y=3/2 or y=2

Anyone know this ???

Make into improper fraction

5 and 1/6=5+1/6=30/6+1/6=31/6

3 and 2/4=3+2/4=3+1/2=6/2+1/2=7/2

5 and 1/6 times 2 and 2/4=
31/6 times 7/2=

Given g(x)=Squareroot x-4 and h(x)=2x-8, what is g(h(10))

yan [13]

Answer:

$g(h(10)) = 2\sqrt 2$

Step-by-step explanation:

Given

$g(x) = \sqrt {x - 4$

$h(x) = 2x - 8$

Required

$g(h(10))$

First, calculate $g(h(x))$

We have:

$g(x) = \sqrt {x - 4$

This gives:

$g(h(x)) = \sqrt {h(x) - 4$

Substitute $h(x) = 2x - 8$

$g(h(x)) = \sqrt {2x - 8 - 4$

$g(h(x)) = \sqrt {2x - 12$

Substitute $x = 10$

$g(h(10)) = \sqrt {2*10 - 12$

$g(h(10)) = \sqrt {20 - 12$

$g(h(10)) = \sqrt {8\\$

Split

$g(h(10)) = \sqrt {4} * \sqrt 2$

This gives

$g(h(10)) = 2\sqrt 2$
