Answer:
Step-by-step explanation:
so what you want to do is take -1/4x+2 3/4 and solve for x and once you got what x is plug it in to the second part 1/2^x +1
Answer:
n
Step-by-step explanation:
n
Answer:
I'm going to say it's the third one (bottom left) because it's the only one that has points scattered in the same vicinity as the graph when I plugged in that equation. The line showed was linear and had many points including (0,15), (1, 16), and (2, 17).
The value of c is 4 feet for the given triangle it is obtained by law of cosines formula.
Step-by-step explanation:
The given is,
Triangular diagram with side dimensions
Step:1
Law of Cosines formula is,
.......................(1)
From the given diagram,
a = 8 feet
b = 7 feet
Angle, C = 32°
Substitute the values then equation (1) becomes,
Substitute the value of cos 32°
(∵ )
Take square root on both sides the above equation becomes,
c ≅ 4 feet
Result:
The value of c is 4 feet for the given triangle it is obtained by law of cosines formula.
Answer:
x=19°
Step-by-step explanation:
Line n and l form a right angle. We know that because line m and l are parallel to each other and line n crosses through them as a vertical line.
Right angles always add up to 90°.
So, Angle 1 add Angle 2 equals 90°.
4x+9+x-14=90°
Collect the like terms:
Like terms are terms with the same variables and powers.
4x+x=5x
9-14= -5
Form an equation:
5x-5=90°
Do inverse operations to isolate x.
90+5=95°
95÷5=19° (We divide by 5 because, in algebra, when a number is next to a letter, it means times, so we have to do the opposite and divide).
So, x=19°
Hope this helps :)
