Answer:
1/4x -3
Step-by-step explanation:
To find the inverse of a function, exchange x and y and then solve for y
y =4x+12
Exchange x and y
x = 4y+12
Solve for y
Subtract 12 from each side
x-12 = 4y+12-12
x-12 = 4y
Divide by 4
(x-12)/4 = 4y/4
The inverse is
1/4x -3
Answer:
D
Step-by-step explanation:
90-55=35 degrees ;)
I'll help you out with 3 questions.
For #1, you kind of figured it out yourself
That 90 degree angle on paper means that m/1 and m/2 make up 90
If m1 is 50, then just subtract m1 (50) from 90, making it 40. m/2 is 40
If Angle M4 is 45 degrees then angle M3 is 180-45 since they both make up a 180 degree angle.
There are 180 degrees in a triangle
If m 8 = 78
and m 9 = 60
m 10 is 180 - 78 - 60
Answer:
75 degrees
Step-by-step explanation:
let x unknown number
5x+10x+9x=180
24x=180
x=7.5
largest angle
10x
10×7.5=75
