Plz Only Answer Question If You Are Sure... Will Give Brainliest+5 Stars+thanks For A Good Explanation

Answers

Answer 1

Find the value of n.

(-y + 5.3) + (7.2y - 9) = 6.2y + n

Transfer 6.2y to the other side and change its sign.

(-y + 5.3) + (7.2y - 9) - 6.2y = n

Solve for the value of n.

-y + 5.3 + 7.2y - 9 - 6.2y = n

group like terms

-y + 7.2y - 6.2y + 5.3 - 9 = n

0 + (-3.7) = n

-3.7 = n

Substitute n with its value.

(-y + 5.3) + (7.2y - 9) = 6.2y + n

(-y + 5.3) + (7.2y - 9) = 6.2y + (-3.7)

-y + 5.3 + 7.2y - 9 = 6.2y - 3.7

Group like terms

-y + 7.2y + 5.3 - 9 = 6.2y - 3.7

6.2y - 3.7 = 6.2y - 3.7

Hope this Helps

X^2y12/ xy^5

= x^2–1 • y^12–5

= xy^7

Answer:

[tex]xy^7=x^ay^b[/tex]

Step-by-step explanation:

[tex]\frac{x^2(y^3)^4}{xy^5} = x^a * y^b[/tex] = [tex]\frac{x^2(y^12)}{xy^5} = x^a * y^b[/tex]

[tex]\frac{x^2(y^12)}{xy^5} = x^a * y^b[/tex] = [tex]\frac{x^2(y^7)}{x} = x^a y^b[/tex]

[tex]\frac{x^2(y^7)}{x} = x^a y^b[/tex] = [tex]x^1y^7 = x^ay^b[/tex]

[tex]x^1y^7 = x^ay^b[/tex] = [tex]xy^7=x^ay^b[/tex]

How is an exponential growth function of the form ​f(x)=a(1+r)^x related to an exponential function of the form ​f(x)=a*b^x?
A.
The value of a is the growth​ factor, and b is equal to the initial amount r.
B.
The value of a is the growth​ factor, and b is equal to the initial amount ​(1+​r).
C.
The value of a is the initial​ amount, and b is equal to the growth factor ​(1+​r).
D.
The value of a is the initial​ amount, and b is equal to the growth factor r.

Answers

The true statement is (c) the value of a is the initial​ amount, and b is equal to the growth factor ​(1+​r).

How to compare the functions?

The functions are given as:

f(x) = a(1 + r)^x

f(x) = a * b^x

An exponential growth function is represented as:

y = ab^x

Where

a represents the initial valueb represents the rate

By comparison:

b = 1 + r

Hence, the true statement is (c) the value of a is the initial​ amount, and b is equal to the growth factor ​(1+​r).
