Find the equation of a line that is perpendicular line to y = 10x - 45 and goes through (1, 1).

Airida [17]

The line $y = 10x - 45$ is already written in the $y = mx+q$ form. This means that $m$ is the slope. If two lines are perpendicular, their slopes are the anti-inverse of each other, i.e. their product is -1.

So, our perpendicular line has a slope of $-\frac{1}{10}$

Finally, we want a line passing through (1,1) with slope $-\frac{1}{10}$ :

$y-1 = -\dfrac{1}{10}(x-1) \iff y = -\dfrac{x}{10} + \dfrac{1}{10}+1 = -\dfrac{x}{10} + \dfrac{11}{10}$

Convert 185 degrees Celsius to degrees Fahrenheit. Round your answer to the nearest degree

Hello! :3

Answer:

The Correct Answer is 365 °F

Step-by-step explanation:

The C to F formula is $(C ~x~ 9/5) + 32 = F$

When we do 185 for C in the formula, we get $(185 ~x~ 9/5) + 32 = F.$

To solve, $(185 ~x~ 9/5) + 32 = F.$ we first multiply 9 by 185, then we divide the product by 5, and then finally we add 32 to the quotient to get the answer.

$185~x~9=1665$
