Answer:
x=7
Step-by-step explanation:
AC=3x+3 AB=-1+2x and BC=11
AC = AB + BC
ALL THE STEPS:
3 X + 3 = - 1 + 2 X + 11
3 X + 3 = 2 X + 10
3 X + ( - 2 X ) + 3 = 2 X + ( - 2 X ) + 10
X + 3 = 10
X + 3 + ( - 3 ) = 10 + ( - 3 )
X = 7
Answer:
The inverse of the function h(x) is
.
Step-by-step explanation:
The given function is

Replace h(x) by y.

Interchange x and y.

Subtract 4 from both sides to isolate variable y,

Multiply both sides by 2.

Divide both sides by 5.

Replace y by h⁻¹(x).

Therefore the inverse of the function h(x) is
.
Answer:
Pretty sure its A and B
Step-by-step explanation:
Slope is -6/5, so that leaves just A B and E
Plugged it in, only A and B were correct
6 I think because 6•3=18, 6•7=42, and 6•2=12
