I think you mean the inverse
to find it
switch x and y
solve for y
replace y with f⁻¹(x)
y=5x-10
x=5y-10
x+10=5y
1/5x+2=y
f⁻¹(x)=1/5x+2
Answer:
y=2/3+4
Step-by-step explanation:
This equation is in Slope-Intercept form, the most common, therefore, y=-2/-3+4 just needs to apply the - x - = + rule to get, y=2/3+4
Answer:
option 4
Step-by-step explanation:
using the sine/ cosine ratios in the right triangle and the exact values
cos30° = 
, sin30° = 
, then
cos30° = 
= 
= ( cross- multiply )
2x = 20
× = 20 × 3 = 60 ( divide both sides by 2 )
x = 30
and
sin30° = 
= 
= ( cross- multiply )
2y = 20 ( divide both sides by 2 )
y = 10
The slope is 2 I’m pretty sure
12^2 + 9^2 = 225
the square root of 225 = 15
x = 15
