Raphael sells paintings for $200 each at a market but has to pay $100 to reserve a table.
Answer:
Raphael sells paintings for $200 each at a market, but has to pay $100 to reserve a table. :)
Step-by-step explanation:
The scenario that describes a proportional relationship is D; Raphael sells paintings for $200 each at a market but has to pay $100 to reserve a table.
What is directly proportional and inversely proportional relationship?Let there are two variables p and q
Then, p and q are said to be directly proportional to each other if
p = kq
where k is some constant number called constant of proportionality.
This directly proportional relationship between p and q is written as
[tex]p \propto q[/tex]where that middle sign is the sign of proportionality.
This inversely proportional relationship is denoted by;
[tex]m \propto \dfrac{1}{n} \\\\ \text{or} \\\\n \propto \dfrac{1}{m}[/tex]
Thus, the scenario that describes a proportional relationship is D; Raphael sells paintings for $200 each at a market but has to pay $100 to reserve a table.

whats 9+10 ? ;) im dumb so i dont know simple mafs
Answer:
the answer is 100% = 21
Step-by-step explanation:
Given the equation f(t) = 225(1.23)
What is the rate of growth or decay?
%
What is the initial value?
Answer:
This function doesn't make sense, unless you make it f(t)=225(1.23)^x. I will assume that you forgot to add the x squared. The rate of decay is 23%. Since the base is between 1 and 0, it is an exponential decay and you'll need to subtract the r-value with 1. (If it were an exponential growth, you would have to add 1.) The initial value or the a-value is 225.
If there are 2.54 centimeters in an inch and 12 inches in a foot, how many centimeters in 3 feet
Answer:
91.44
Step-by-step explanation:
Answer:
3 ft = 91.44 cm
Step-by-step explanation:
We want to convert 3 ft to cm.
So we need a conversion factor.
Multiplying 3 ft by (12 in / 1 ft results in 36 in (this is equivalent to 3 ft).
Next, we convert 36 in to cm:
36 in 2.54 cm
-------- * ------------- = 91.44 cm
1 1 in
Prove the following statement: If the x- and y-intercepts of a line are identical nonzero numbers, the line must have a slope of -1.
What is the x-intercept you are using?
What is the y-intercept you are using?
Show what you did to prove the slope is -1
Answer:
Step-by-step explanation:
Proof:
If:
x intercept is at a number nonzero "a"
so the point where it intersects the x-axis is at (a,0)
y-intercept is at the same nonzeronumber "a"
so the point where it intersects the y-axis is at (0,a)
Then:
slope between point (a,0) and (0,a) is m= (y2-y1)/(x2-x1) = 0-a/a-0=-a/a= -1
x intercept is 2 (for example)
so the point where it intersects the x-axis is at (2,0)
y-intercept is 2
so the point where it intersects the y-axis is at (0,2)
slope between point (2,0) and (0,2) is m= (y2-y1)/(x2-x1) = 0-2/2-0=-2/2=-1

If the value of y varies directly with x, which function represents the relationship between x and y when y = 16/5
and X=20
A. Y=25/4x
B. Y=116/5x
C. Y=4/25x
D. Y=64x
Answer:
C. Y=4/25x
Step-by-step explanation:
If y varies directly as x, tis is expressed as;
y ∝ x
y = kx
k is the constant of proportionality
Goven
y = 16/5 and x = 20
16/5 = 20k
16 = 100k
k = 16/100
k = 4/25
Substitute k = 4/25 into the original equation
y = kx
y = 4/25 x
Hence the required expression is y = 4/25 x

Consider the equation 6*e^{0.25t}=9
Solve the equation for t. Express the solution as a logarithm in base-e.
Approximate the value of t. Round your answer to the nearest thousandth
Answer:
t = ln1.5/0.25
t = 1.622
Step-by-step explanation:
Gives the equation, 6*e^{0.25t}=9
We are to find t
6*e^{0.25t}=9
e^{0.25t}=9/6
e^{0.25t}= 1.5
Apply ln to both Sides
ln( e^{0.25t) = ln1.5
0.25t = ln1.5
t = ln1.5/0.25
t = 1.622

please be fast ill give brainliest How many solutions does the system have? y=1/2x-1 and y=-x+5
Answer:
(4, 1)
Step-by-step explanation:
since y=1/2x-1 in the first equation, you can substitute it into the second one:
1/2x - 1 = -x + 5
then add x to both sides:
3/2x - 1 = 5
then add 1 to both sides:
3/2x = 6
then divide both sides by the fraction to get:
x=4
then you substitute 4 into y=1/2x - 1
y = 1/2(4)-1
y = 1
so your answer is x=4 and y=1
