Answer:
Initial Value=15
Rate of change=15/10=1.5
Equation: y=1.5x+15
Step-by-step explanation:
y=ax+b
y=1.5x+b
15=1.5(0)+b
b=15
<h2>
Answer:</h2>
is 3 ohms
<h2>
Step-by-step explanation:</h2>
In a circuit containing two resistors 
and connected together in parallel, the total resistance 
is given by;
---------(i)
<em>Make </em><em> subject of the formula;</em>
=> 
=> 
=> 
---------------(ii)
From the question,
= 6Ω
= 2Ω
Substitute these values into equation (ii) as follows;
=> 
= 3Ω
Therefore, the value of = 3 ohms or = 3Ω
5 days does it take to sell 640 cupcakes.
Given:
A bakery sells 4 dozen cupcakes every 3 hours.
If the bakery is open 8 hours each day.
4 dozen cupcakes = 4*12 cupcakes
= 48 cupcakes
48 cupcakes = 3 hours
divide by 3 on both sides
3hours/3 = 48/3 cupcakes
1 hour = 16 cupcakes
Number of cupcakes for 8 hours = 8 * 16 = 128 cupcakes.
128 cupcakes sells in one day.
To sell 640 cupcakes = 640/128
= 5 days.
Therefore 5 days does it take to sell 640 cupcakes.

Answer:
It is a GP.
Step-by-step explanation:
a = 3
r = 2
a(n) term = ar^n
As it increases as multiples, it is a geometric progression or a GP.
Answer:
23+19+27+x = 96
x > 27
not sure if the answer can be left that way or do you assume that test results are whole numbers, if so then the answer would b=have to be 28.. but I think that >27 is the answer expected
