Im not sure why you said ur wrong b/c i got the same answer
f(x) = -15+ 7
f(x) = -8
Step-by-step explanation:
To write the equation in LaTeX in form y = ab^x or
for y = abx .........(1)
(a) LaTeX: y=3\sqrt{4^{2x}} y = 3 4 2 x can be written in mathematical form as
; y = 342x
on comparing with equation (1) we get a =3 and b =4
⇒y = 34^x or 
(b) LaTeX: y=\frac{\sqrt[3]{5^{3x}}}{2} y = 5 3 x 3 2 can be written in mathematical form as
; y = 342x
on comparing with equation (1) we get a =0.5 and b =5
⇒y =
(c)LaTeX: y=8^{x+2} y = 8 x + 2 can be written in mathematical form as
on comparing with equation (1) we get a =64 and b =8
y = 
(d)LaTeX: y=\frac{3^{2x+1}}{\sqrt{3^{2x}}} can be written in mathematical form as
=
= 
on comparing with equation (1) we get a =3 and b =3
y =
Answer:
71.5
Step-by-step explanation:
x+1 so (1+10) x (21+5)= 286
but then 1+1=2 and 2x2= 4 so 286 divided by 4= 71.5
Answer:
See below.
Step-by-step explanation:
For each size, divide the cost by the amount. Make sure the amounts are all in the same units. Then, the lowest cost per unit is the best buy.
Answer:
f(h(x))= 2x-4
Step-by-step explanation:
f(h(x))=f(2x+3)=2x+3-7= 2x-4
