Answer:
![h(x) = \frac{1}{2} x+ 5](https://tex.z-dn.net/?f=h%28x%29%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20x%2B%205)
Step-by-step explanation:
To find the inverse of a function, simply switch the 'x' and 'y' variables. Substitute in 'y' in the place of f(x) for this purpose:
y = 2x - 10
Switch positions:
x = 2y - 10
Add '10' to both sides to begin simplifying:
x + 10 = 2y
Divide both sides by 2:
![y= \frac{x+10}{2}](https://tex.z-dn.net/?f=y%3D%20%5Cfrac%7Bx%2B10%7D%7B2%7D)
This can be rewritten as:
![y = \frac{1}{2} x+ 5](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20x%2B%205)
Therefore, the inverse of the function is:
![h(x) = \frac{1}{2} x+ 5](https://tex.z-dn.net/?f=h%28x%29%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20x%2B%205)

answer
x=6,y=14
Step-by-step explanation:
make -5x+5x=40 as equation (1)
4x+3y=24...... (2)
Find equation (3) from (1)
-5x+5y=40
-5x/-5=(40-5y)-5
x= y-8............. (3)
Substitute (3) from (2)
4x+3y=24
4 (y-8)+3y=24
4y-32=24
4y=24+32
4y=56
y=14
find x from equation (3)
x=y-8
x=14-8
x=6
Find the perimiter now
that is right triangle so
when hpotonouse is c and hthe lgs are a and b
a²+b²=c²
given
leg is 8
hypotonuse is 13
8²+b²=13²
64+b²=169
minus 64 from both sides
b²=105
sqrt both sides
b=√105
find total perimiter
8+13+√105=21+√105
times 1/32 for scale
