Answer:
Step-by-step explanation:
The sum of the angle measures of a triangle is 180°. Find the value of x . Then find the angle measures of the triangle.
find the value of x
x + 2x + x + 8 = 180
4x = 180 - 8
4x = 172
x = 172 : 4
x = 43
find angles
2x = 43 * 2
2x = 86°
-------
x = 43°
--------
x + 8 = 43 + 8
x = 51°
-----------------------
check
86 + 43 + 51 = 180°
the answer is good
Answer:
22rs
Step-by-step explanation:
Hope this helps! :D
Well if you think about it, you are given 2 equations. lets say the 2 numbers ar x and y
it says one number that we willl call y is 4 times another number we will call x. so:
y = 4 * x
the other part says their difference is 24. well y has to be the larger number sincenit is 4 times x. so:
y - x = 24
in the first part i said y = 4x so i know what y equals. i can plug this into thenother equation like this
y - x = 24
(4x) - x = 24
3x = 24
x = 8
i have x. i can plug this in first equation to find y
y = 4x
y = 4 (8)
y = 32
we can checj by plugging in x and y to both equations. if it matches we are.good
y = 4x
32 = 4 (8)
32 = 32
y - x = 24
(32) - (8) = 24
24 = 24
it all works out
Step-by-step explanation:
dy/dx
= d/dx [x / (1 - x²)]
= [(1 - x²)(1) - (x)(-2x)] / (1 - x²)²
= (1 + x²) / (1 - x²)².
When dy/dx = 1, (1 + x²) / (1 - x²)² = 1.
=> 1 + x² = 1 - x²
=> 2x² = 0, x = 0.
Also when x = 0, y = (0) / [1 - (0)²] = 0.
Hence the coodinates is (0, 0).
Answer:
6, 26
Step-by-step explanation:
because x is 6 so itll be -3(6)=-8
-3 times 8 is -26
y=-26
