Answer:
18 but look at others awnsers aswell
Step-by-step explanation:
Answer:
a = 5
Step-by-step explanation:
If it's easier for you, you can replace n(a) with y and put a as x.
Now the equation is y = 7x + 4.
It asks you to put in 39 as y.
39 = 7x + 4.
To solve this, the goal is to isolate the variable on one side. The first step I see is to subtract the 4 from both sides.
35 = 7x
Now divide both sides by 7 and we're done!
5 = x
In this situation you would use cos
which is adjacent over hypotenuse
so I take the cos50 and have it equal to 17 / x
cos(50)= 17/x
which is the same as ...
17 divided by cos(50) =x
x=26.44730506
which rounds to 26.45
So your answer would be A)
I hope everything makes sense, enjoy! <span />
Before the fraction: -1/2, i have a negative sign
use y=mx+b
3=-1/2(2)+b
3+1=-1+b+1
4=b
check your work
0=-1/2x+4
0+4=-1/2x
(4)÷(-1/2)=(-1/2x)÷(-1/2)
-2=x
another pair is (-2,0) use this to figure out the other points, and/or the points you have in the multiple choice.
There is no way to measure this. However, if it was multiple choice with four possible answers, and one was correct, then you would have a 25% chance of getting it right.
