2+x=7 x=5 eso es todo
7-2=x
7-z=2
Answer: nigwa idek good luck
Step-by-step explanation:
<span> (x2 + 4) • (x + 5) • (x - 5)</span>
Y = 2x - 10
2x = y + 10
x = (y + 10)/2
Therefore, f^-1(x) = (x + 10)/2
Answer:
g(1)=7 1/5
Step-by-step explanation:
vertex (-5,0) , y intercept(0,5)
the quadratic equation is in the form of a parabola: y=ax²+bx+c
y=a(x-h)²+k find a and b and c
5=a(0-(-5))²+0
5=a(5)²+0
5=25a ⇒ a=5/25 ⇒ a=1/5
-b/2a=h
-b=2ah ⇒=-b=2(1/5)(-5) ⇒ -b=-2⇒ b=2
y=c=5 ( when x=0, y intercept)
y=1/5x² + 2x + 5
g(1)=1/5(1)²+2(1)+5
g(1)=1/5+2+5
g(1)=7 1/5
