Answer:
x = -pi/2
Step-by-step explanation:
hello :
f(x)=sin x x⋲(-2pi,0)
the derivate for f is : f'(x) = cosx
f(x) achieve a minimum when : f'(x) =0
cosx = 0 genral solution is :
x = pi/2 +kpi .. k in Z
but : x⋲(-2pi,0) so : x = -pi/2.....(k = -1)
Answer:
The answer is y= −6
Step-by-step explanation:
Let's solve your equation step-by-step.
10−5y=2(14−y)
Step 1: Simplify both sides of the equation.
10−5y=2(14−y)
10+−5y=(2)(14)+(2)(−y)(Distribute)
10+−5y=28+−2y
−5y+10=−2y+28
Step 2: Add 2y to both sides.
−5y+10+2y=−2y+28+2y
−3y+10=28
Step 3: Subtract 10 from both sides.
−3y+10−10=28−10
−3y=18
Step 4: Divide both sides by -3.
−3y/−3=18/−3
y=−6
Answer:
y=−6
I am slightly confused by your wording in the last sentence, but if you are trying to figure out how many children attended the concert you would use the second statement. The first statement does not tell you if the students are "children" are not so that is not an appropriate choice.<span />
