Answer:
s=32
Step-by-step explanation:
15x-31 = 9x+11
6x=42
x=7
2(63+11)= 2(74)= 148
180-148=32
Answer:
16
Step-by-step explanation:
2x+3 = 11
2x= 8
x = 4
4(x) = 4(4) = 16
Step-by-step explanation:
The 2 lines are parallel to each other which means that angle #5 and 93° are alternate interior angles so by definition, they are equal. Hence angle 5 = 93°
Answer:
y = 2x - 12
Step-by-step explanation:
To find the inverse of a function, you switch x and y and solve for y.
x = 1/2 y + 6 switch x and y
x - 6 = 1/2 y subtract 6 from both sides
2x - 12 = y multiply both sides by 2
