Answer:
10
Step-by-step explanation:
2[45/(11-8)^2]
=2[45/(3)^2]
=2[45/9]
=2[5]
=10
Answer:
f(x) = x
Step-by-step explanation:
note : slope is positive 1, so the x term must be positive
also note the graph intersects the curve at y = 0, which means that they y-intercept is zero .
if we substitute this into the general equation for a line
y = mx + b, where m = +1 and b = 0,
we get y = x
or f(x) = x (in function form)
Sharon's age= 2x
Brian's age= x
(2x-5)+(x-5)= 25
3x-10=25
3x=15
x=5
Brian is 5 years old and Sharon is 10
Answer:
Original equation: C-21=16
Add 21 to both sides: C=37
Hope this helps!
