East high school's student council plans to buy some stools and chairs for a new student center. They need to buy 25 more chairs than stools. The chairs cost $32 each and the stools cost $28 each. The budget is $2,620. How many chairs can they buy?

im sorry your friend got fired

Step-by-step explanation:

Substitutex=cos\alp,\alp∈[0:;π] \displaystyle Then\; |x+\sqrt{1-x^2}|=\sqrt{2}(2x^2-1)\Leftright |cos\alp +sin\alp |=\sqrt{2}(2cos^2\alp -1)Then∣x+ 1−x 2 ​ ∣= 2 ​ (2x 2 −1)\Leftright∣cos\alp+sin\alp∣= 2 ​ (2cos 2 \alp−1) \displaystyle |\N {\sqrt{2}}cos(\alp-\frac{\pi}{4})|=\N {\sqrt{2}}cos(2\alp )\Right \alp\in[0\: ;\: \frac{\pi}{4}]\cup [\frac{3\pi}{4}\: ;\: \pi]∣N 2 ​ cos(\alp− 4 π ​ )∣=N 2 ​ cos(2\alp)\Right\alp∈[0; 4 π ​ ]∪[ 4 3π ​ ;π] 1) \displaystyle \alp \in [0\: ;\: \frac{\pi}{4}]\alp∈[0; 4 π ​ ] \displaystyle cos(\alp -\frac{\pi}{4})=cos(2\alp )\dotscos(\alp− 4 π ​ )=cos(2\alp)… 2. \displaystyle \alp\in [\frac{3\pi}{4}\: ;\: \pi]\alp∈[ 4 3π ​ ;π] \displaystyle -cos(\alp -\frac{\pi}{4})=cos(2\alp )\dots−cos(\alp− 4 π ​ )=cos(2\alp)

im pretty sure its

step-by-step explanation:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
