Answer:
B. x < 17
Step-by-step explanation:
x is a leg of right triangle ADC, so must have a length less than the hypotenuse. (x < 20)
x is a leg of triangle ABC, so must have a length between 20-17 = 3 and 20+17=37. The first restriction limits x to ...
3 < x < 20 . . . . . allows x ≥ 17
The Pythagorean theorem applied to the right triangle requires ...
x^2 +y^2 = 400
Angle ABC is opposite side AC, which has length 20. Angle BAC is opposite side BC, which has length 17. The longer length of AC means that angle B will always be greater than angle A in triangle ABC.
__
The only condition that is <em>not necessarily true</em> is ...
x < 17
Answer: Option B.
![b=\frac{5}{4}](https://tex.z-dn.net/?f=b%3D%5Cfrac%7B5%7D%7B4%7D)
Step-by-step explanation:
If a varies directly with b then when a increases b it also increases by a factor k.
Then we can write that
![a = kb](https://tex.z-dn.net/?f=a%20%3D%20kb)
We know that when a = 28 then b = 7. So
![28 = k * 7](https://tex.z-dn.net/?f=28%20%3D%20k%20%2A%207)
![k=\frac{28}{7}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7B28%7D%7B7%7D)
![k=4](https://tex.z-dn.net/?f=k%3D4)
Therefore the equation of proportionality is:
![a=4b](https://tex.z-dn.net/?f=a%3D4b)
So when
then:
![5=4b\\\\b=\frac{5}{4}](https://tex.z-dn.net/?f=5%3D4b%5C%5C%5C%5Cb%3D%5Cfrac%7B5%7D%7B4%7D)
The answer is 3x - 5y = 26 i believe !
