Answer:
A = 20,000(1.05)^x
Step-by-step explanation:
To get the approximate value of the house after x years, we will use the compound interest formula
A = P(1+r)^n
P is the principal = $20,000 (cost of house)
r is the rate = 5% = 0.05
x is the time
Substitute into the expressio
A = 20,000(1+0.05)^x
A = 20,000(1.05)^x
Hence the required expression is A = 20,000(1.05)^x
Answer:
c
Step-by-step explanation:
Answer:y=2.5 x
Step-by-step explanation:
Given
Cow give 5 gallon of milk if it eats 2 pound of grass
i.e. it gives 2.5 gallon of milk if it eats 1 pound of grass
So we can say cow given 2.5 times of milk in gallon for each pound it eats
If cow eats x pounds of grass then it must yield 2.5 times of milk
Suppose milk is denoted by y
therefore we can write
y=2.5 x
Therefore y=2.5 x represent the relation between grass and milk produced
Additive indentity
n = 1
a variable is always a number itself remember 7+n
5+2 = 7
Answer:
7
Step-by-step explanation:
We have that x1=−1, y1=5, x2=3, y2=7.
Plug the given values into the formula for a slope: m=7−(5)3−(−1)=12.
Now, the y-intercept is b=y1−mx1 (or b=y2−mx2, the result is the same).
b=5−(12)(−1)=112
Finally, the equation of the line can be written in the form y=b+mx:
y=112+x2
