The table shows the price for different numbers of cupcakes: Number of Cupcakes Price (in dollars) 3 12 4 16 5 20 7 28 Does this table of numbers represent a proportional relationship? Yes, because 4 times the price is the number of cupcakes Yes, because the price is 4 times the number of cupcakes No, because the price of 4 cupcakes should be $13 and not $12 No, because the price of 5 cupcakes should be $60 and not $20
Answers
3 x 4 = 12
4 x 4 = 16
5 x 4 = 20
7 x 4 = 28
Your proof is true because it is x4 the next value.
12 + 4 = 16
16 + 4 = 20
20 + 4 = 24
Hope I helped! :)

So here is one example,
length of rectangle is 10 units and width is 2.5 units and perimeter is 2×(l+b)
=> 2×(10+2.5)
=> 2×12.5
=> 25 units.

Answer:

Step by Step Explanation:
f(n+1) = 2f(n) + 10
a = 2, k = 10
a + k = 2 + 10 = 12
Answer:
12
Step-by-step explanation:
if I have understood the question correctly
f(n+1) = a*f(n) + k
using two consecutive values of the given sequence
500 = a*245 + k or it can be written as a*245+k -500 = 0
1010 = a*500+k or it can be written as a*500+k - 1010 = 0
therefore
a*245+k -500 = a*500+k - 1010
a*245-a*500 = -1010 + 500
-255a = -510 a=510/255=2
using this value in the original equation
500 = 2 *245 + k
k = 500 - 2 *245 = 10
a+k = 2+10 = 12

What is a linear equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
Let, consider the equation of y = mx+c,
where, m is the slope of line and c is the y - intercepts. So to draw the graph firstly we find the two points to connect the line in which first is y-intercepts by putting x=0 in the given equation.
standard form of linear equation is :
y = mx+c
comparing it with given equation :
y= -2x-9.
m = -2, c = -9
Therefore, y= -2x-9 is in standard form itself with slope m = -2 and y intercept c as -9.

standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient
2x + y = -9.
