Answer:
x=7
Step-by-step explanation:
since it is the same side length,
3x+6 = 10x-43
3x-10x = -43-6
-7x = -49
x=-49/-7=7

Answer: y + 2 = ( x - 4 )
Step-by-step explanation:
The equation of a line in point - slope form is given as ;
y - = m (x - )
= 4
= -2
m =
Substitute the values into the equation , we have
y - (-2) = ( x - 4 )
y + 2 = ( x - 4 )
Which could be written as :
y + 2 = y + 2 = x + 2
It's linear
If you evaluate x when it's 0 you'll get the cut in y, that means the function will pass on (0,7)
The formula for linear functions is y=mx +b
In this case b is 7
M=7-5/0+1
M=2
Now you just write the function down, it would be
F(x) =2x + 7
Answer:
Step-by-step explanation:
First rewrite as y
Now swap y and x
Add 8 on both sides.
Divide by 4.
Extract the square root on both sides.
Subtract 3 on both sides.
