Answer:
40
Step-by-step explanation:
The entire line is 180°
since 140° is occupied, there is a 40° angle.
I hope isn't too late :'(
Question 1:Multiply both sides of the proportion by 35.
You get.
7(x-1) = 4x+2
7x-7 = 4x+2
Now, add both sides by 7 and subtract both sides by 4x
3x = 9
Divide both sides by 3
x=3
Question 2:Multiply both the numerator and the denominator of
by 3.
We want to multiply it by 3 so that the +1 and +3 become +3 and +9. +3 and +9 have a difference of 6, just like 15 and 21, which is what we want.
Set the numerator equal to the numerator and the denominator equal to the denominator.
3x+3 = 15
3x+9 = 21
If you solve both of these, you get x=4 for both.
That's your answer.
Hope this helps! :)
Answer:
Step-by-step explanation:
f(x)/g(x)=(6x+2)/(x-7)
The only restriction upon the domain, possible values of x, is division by zero is undefined. So x cannot equal 7.
So the domain is all real numbers except 7. In interval notation the domain is
x=(-oo, 7),(7, +oo)
Answer:
<u><em>Based on two Pythagorean Identities:</em></u>
- 1 + tan²θ = sec²θ
- 1 + cot²θ = csc²θ
sec²θ(1 - cot²θ)
= sec²θ - sec²θ · cot²θ
Answer: Your answer should be "1"! I hope this helps!^^
Step-by-step explanation:
f(1/2)=4(1/2)^2−2(1/2)+1
f(1/2)=1−1+1
f(1/2)=1
Final answer is 1 :D
