Answer:

9/4 (1.75 - 21/4)

=2.25 -3.5

= -1.25

I think your f answer is wrong

there should be -1.25

If h(x)=6-x what is the value of (h•h)(110)
Irina18 [472]

The given function : h(x) = 6 - x

We know that for any functions f(x) and g(x)

f*g (x)=f(x)\times g(x)

Therefore , h*h (x)=h(x)\times h(x)

h*h (x)=(6-x)(6-x)=(6-x)^2

h*h (x)=(6)^2-2(6)(x)+x^2 [ Using identity   (a-b)^2=a^2+2ab+b^2 ]

h*h (x)=36-12(x)+x^2

\-------->\ h*h (x)=36-12(x)+x^2 Now, at x= 10 , we get

h*h (10)=36-12(10)+(10)^2

h*h (10)=36-120+100=36+100-120=136-120=16

Hence, the value of (h*h)(10) = 16

hoped it helped

20. Sofia paid $11.80 for a pen, a marker, and a binder. The marker cost $0.80 more than the pen. The binder cost 4 times as muc
7nadin3 [17]

Answer:

$1.30

Step-by-step explanation:

Let x = the cost of the pencil

Let x + .80 = the cost of the pen

Let 4(x + .80) = the cost of the binder

x + x + .80 + 4(x + .80) = 11.80

2x + .80 + 4x + 3.20 = 11.80

6x + 4.00 = 11.80

6x = 7.80

x = $1.30

x + .80 = $2.10

4(x + .80) = $8.40

Classify each pair of numbered angles.
kifflom [539]
Adjacent angles are angles with a common side and vertex, linear pairs are adjacent angles that are supplementary, and vertical angles are angles made by the same two lines but on opposite sides.

For the first one, 5 and 6 clearly do not share a side but they are made up by the same 2 lines and are opposite of each other, making them vertical.

For the next one, since the angles only share 1 line (and not a side) they can't be any of the above.
