15 + 17r - 4r - 9 = 9
6 + 13r = 9
13r = -3
r = -3/13
:)
Answer:
(1c times 9/5) +32
That is the way to figure out °1c as 33.8°
Hope it helped
2. Is 65
3. X is 12
Hope this helps
Hey there!!
We have:
... x² + y² = 25
... x² + y² = 5²
... y² = 5² - x²
and
... y² - 2x = 25
... y² - 2x = 5²
We know y² = 5² - x²
... 5²-x²-2x = 5²
... -x² - 2x = 5²-5²
... -x² - 2x = 0
... x(-x-2) = 0
... -x-2 = 0
... -x = 2
... x = -2
<em>Hence, the value of x is -2. </em>
... x² + y² = 25
... (-2)² + y² = 25
... 4 + y² = 25
... y² = 25 - 4
... y² = 21
... y = √21
<em>Hence, the value of 'y' is √21. </em>
Hope my answer helps!!
