Answer:
g(x) = 3.5^x-2
Step-by-step explanation:
because g(0) = 3.5^0-2 = -1 and g(1) = 3.5^1-2 = 1.5
you know that g(x) = y and when x=0 y=-1 on the graph
and when x=1 y=1.5
 
        
             
        
        
        
Answer:
The cost of one rose is $11., and the cost of one geranium is $5.
Step-by-step explanation:
The cost of one rose bush and one geranium can be determined by the use of simultaneous equation. Let the cost of a rose bush be represented by x, and the cost of one geranium by y.
So that,
13x + y = 148 .............. 1
9x + 14 y = 169 ............... 2
From eqaution 1,
y = 148 - 13x ............... 3
substitute the value of y in equation 2
9x + 14(148 - 13x) = 169
9x + 2072 - 182x = 169
2072 - 169 = 182x - 9x
1903 = 173x
x = 
   = 11
x = 11
substitute the value of x in equation 3
y = 148 - 13x
   = 148 - 13(11)
   = 148 - 143
y = 5
x = 11, y = 5
Thus, the cost of one rose is $11., and the cost of one geranium is $5.

Answer:
13/28.
Step-by-step explanation:
(8/14 - 2/8) + 1/7
We can just remove the parentheses and simplify its contents:
=  4/7 - 1/4 + 1/7
= 4/7 + 1/7 - 1/4
= 5/7 - 1/4      The LCD of 7 and 4 is 28 so we have:
20/28 - 7/28
= 13/28.
