Each triangle has a sum of angles that equal 180° so set each angle measure = 180
(x + 66) + (x + 86) + 50 = 180; add accordingly
2x + 202 = 180; subtract 202 from both sides
2x = -22; divide both sides by 2
x = -11
Plug in -11 for x to check
(-11 + 66) + (-11 + 86) + 50 = 180
55 + 75 + 50 = 180
180 = 180 so -11 is the correct value of x
So the domain<span> is "all </span>x<span>". To </span>find<span> the </span>domain, I'll ignore the "x<span> + 2" in the numerator (since the numerator does </span>not<span> cause division by zero) and instead I'll look at the denominator. I'll set the denominator equal to zero, and solve. The </span>x-values<span> in the solution will be the </span>x-values<span> which would cause division by zero.</span>
Answer:
x = -9
Explanation:
(3x + 9)^5 = 32x^5
(3 (x + 3))^5 = 32x^5
3^5 (x + 3)^5 = 32x^5
243(x + 3)^5 = 32x^5
243(x + 3)^5 - 32x^5 = 0
x = -9
Answer: 4/5
Step-by-step explanation:
0.8 is 8 tenths which is 8/10 in fraction form
8/10 with both sides divided by two is 4/5
hope this helps u
Answer:
x= 10 and y= -1
Step-by-step explanation:
Rewrite your second equation Y= -2x+ 19 then plug it into the first equation.
x- (-2x + 19) = 11
x + 2x - 19 =11
3x - 19 = 11
3x = 30
x = 10
The plug that answer into the first equation and solve.
10 - y = 11
-y = 1
y = -1
