Probably between obtuse angle or triangle because sometimes they trick you
But I'm not 100 percent sure
Answer:
x = 3
Step-by-step explanation:
7/x - 3/(2x) + 7/6 = 9/x
x(7/x - 3/(2x) + 7/6) = x(9x)
x*7/x - 3*x/(2x) + x*7/6 = x*9x
7 - 3/2 + 7x/6 = 9
7x/6 = 9 - 7 + 3/2
7x/6 = 2 + 3/2
7x/6 = 12/6 + 9/6
7x = 12+9
7x = 21
x = 21/7
x = 3
probe:
7/3 - 3/(2*3) + 7/6 = 9/3
14/6 - 3/6 + 7/6 = 3
(14 - 3 + 7) / 6 = 3
18/6 = 3
Cant really see it like that
Y = x² - 5x + 2
y = -6x + 4
-6x + 4 = x² - 5x + 2
0 = x² - 5x + 2 + 6x - 4
0 = x² + x - 2
(x + 2)(x - 1)
x = -2 ; x = 1
y = x² - 5x + 2 ; x = -2 y = x² - 5x + 2 ; x = 1
y = (-2)² - 5(-2) + 2 y = 1² - 5(1) + 2
y = 4 + 10 + 2 y = 1 - 5 + 2
y = 16 y = -2
y = -6x + 4 ; x = -2 y = -6x + 4 ; x = 1
y = -6(-2) + 4 y = -6(1) + 4
y = 12 + 4 y = -6 + 4
y = 16 y = -2
Choice C. <span>(-2, 16) and (1, -2) is the answer.</span>
So angle 4 and angle 2 are gonna equal 180
So your equation should say
3x - 10 + 70 = 180
3x + 60 = 180
-60 -60
3x = 120
— —
3 3
X = 40
And your answers x = 40
Hope you understood
