Answer: e^y=x
ln(x)=y
e^ln(x)=e^y
x=e^y
The original expression evaluates to 54.4 as shown in the first working.
_____
For some reason, 3.4 got transcribed to be 1.7 in the 3rd line of the second working. There is no math operation in the expression that requires 3.4 to be divided by 2.
Answer:
A) 130
Step-by-step explanation:
(2x + 18) + y = 180 <--- Is True
(4x - 14) + y = 180 <--- Is True
(2x + 18) + y = y + (4x - 14)
(2x + 18) = (4x - 14)
2x + 18 = 4x - 14
-2x + 18 = -14
- 18 - 18
-2x = -32
x = 16
2(16) + 18 = 50
4(16) - 14 = 50
180 - 50 = 130
3(9-x)
=27-3x
Since x=5,
27-(5)3
=27-15
=12
The correct answer is A) y = -1/5x + 1
To find the equation of the line, start by finding the slope. You can do this by using the slope formula below.
m(slope) = (y2 - y1)/(x2 - x1)
m = (2 - -1)/(-5 - 10)
m = 3/-15
m = -1/5
Now that we have the slope, we can use it along with either point in point-slope form to get the equation.
y - y1 = m(x - x1)
y - 2 = -1/5(x + 5)
y - 2 = -1/5x - 1
y = -1/5x + 1
