Answer:
I got 103˚ because I put (x+40)˚ into the calculator
Answer:
Step-by-step explanation:
First make a ratio,
6:62.64
Now make an equation
6/62.64=4/x
solve for x...
x=41.76
Hence, option D 4: x=-1.34 is correct
Further explanation:
In order to solve an equation in one varible we have to isolate the variable on one side of the equations
Given equation is:
![-1.2x=2(x+2.15)\\Simplifying\\-1.2x=2x+4.3\\Subtracting\ 2x\ from\ both\ sides\\-1.2x-2x=2x+4.3-2x\\-3.2x=4.3\\Dividing\ both\ sides\ by\ -3.2\\\frac{-3.2x}{-3.2}=\frac{4.3}{-3.2}\\x=-1.34375\\Rounding\ off\ to\ nearest\ 100th\\x=-1.34](https://tex.z-dn.net/?f=-1.2x%3D2%28x%2B2.15%29%5C%5CSimplifying%5C%5C-1.2x%3D2x%2B4.3%5C%5CSubtracting%5C%202x%5C%20from%5C%20both%5C%20sides%5C%5C-1.2x-2x%3D2x%2B4.3-2x%5C%5C-3.2x%3D4.3%5C%5CDividing%5C%20both%5C%20sides%5C%20by%5C%20-3.2%5C%5C%5Cfrac%7B-3.2x%7D%7B-3.2%7D%3D%5Cfrac%7B4.3%7D%7B-3.2%7D%5C%5Cx%3D-1.34375%5C%5CRounding%5C%20off%5C%20to%5C%20nearest%5C%20100th%5C%5Cx%3D-1.34)

Answer:
The answer is: y = 7
Step-by-step explanation:
For x = 4, it is a vertical line where everything is x = 4. No matter what y is, x always equals 4.
For the line y = 7, it is a horizontal line, perpendicular to the line x = 4. The line y = 7 passes through the point (-1, 7) and all other similar points where y = 7.
