Answer: 12

Step-by-step explanation: f(x) = 7x - 2 means that if we put an <em>x</em> into our function, a 7x -2 comes out.

So if we want to find f(2), that means we are putting a 2 into our function which means that a 7(2) - 2 comes out which simplifies

to 14 - 2 or 12. So f(2) = 12.

Answer:

f(2)=12

Step-by-step explanation:

f(x)=7x-2

Plug 2 into the equation, since it says "f(2)".

f(x)=7(2)-2

f(x)=14-2

f(x)=12, done!

Find the value of x
iVinArrow [24]

Answer:

x = 121

Step-by-step explanation:

Let the measure of the altitude of the given triangle be h units.

By geometric mean theorem:

h =  \sqrt{23 \times x}  \\  \\ h =  \sqrt{23x}  \\  \\ now \: by \: pythagors \: theorem \\  \\  {(x + 11)}^{2}  =  {h}^{2}  +  {x}^{2}  \\  \\   \cancel{{x}^{2}}  + 22x + 121 =  {( \sqrt{23x} )}^{2}  +  \cancel{{x}^{2}} \\  \\ 22x + 121 = 23x \\  \\ 22x - 23x =  - 121 \\  \\  - x =  - 121 \\  \\ x = 121

Find FGH~ HOP. Find the area of X​
yKpoI14uk [10]
First, you put the triangles in a ratio
Then, you ask yourself "what do I have to divide seven by to get 5" so you do 7.5/5 to get that answer (which is to divided by 1.5)
Then, on the other side, you divide 22.5 by 1.5 as well
