Answer:

Infinite Solutions

Step-by-step explanation:

5(x-3)+6=5x-9

5x-15+6=5x-9

5x-9=5x-9

Add 9 to both sides

5x=5x

Divide by 5

x=x

Infinite solutions because any number put in will be right

Answer:

81x^4

Step-by-step explanation:

With exponents, whatever is in the parentheses is multiplied by <u>itself</u> however many times the exponent says.

In this case, you would be solving 3 x 3 x 3 x 3 and (x)^4.

3^4 = 81 with x^4 gives you:

81x^4

Hope this helps you :)

Feather blew out of a bird nest 10 feet in the air. It drifted to the ground at a constant rate of 2 feet per second.
PIT_PIT [208]

The equation that  shows the relationship between the elevation of the feather, y, and the number of Seconds it has been falling is y = -2x + 10

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Independent variables represent function inputs that do not depend on other values, while dependent variables represent function outputs that depends on other values.

Let x represent the time in seconds for the bird feather to reach 10 feet.

Hence:

y = -2x + 10

The equation that  shows the relationship between the elevation of the feather, y, and the number of Seconds it has been falling is y = -2x + 10

A gardener is planting two types of trees:
denpristay [2]

It takes 12 years for both trees to be of same height

<em><u>Solution:</u></em>

Assume the year that it would take to these trees have the same height is : x (years)

<em><u>Type A is 7 feet tall and grows at a rate of 23 inches per year:</u></em>

Convert 7 feet to inches

We know that,

1 foot = 12 inch

7 feet = 12 x 7 inch = 84 inch

Thus, type A is 84 inches tall and grows at a rate of 23 inches per year

We can frame a equation as:

Type A = 84 + 23(number of years)

Type A = 84 + 23x ---------- eqn 1

<em><u>Type B is 5 feet tall and grows at a rate of 25 inches per year</u></em>

Convert 5 feet to inches

5 feet = 5 x 12 inches = 60 inches

Thus, type B is 60 inches tall and grows at a rate of 25 inches per year

We can frame a equation as:

Type B = 60 + 25(number of years)

Type B = 60 + 25x --------- eqn 2

For both the trees to be of same height, eqn 1 must be equal to eqn 2

84 + 23x = 60 + 25x

25x - 23x = 84 - 60

2x = 24

x = 12

Thus it takes 12 years for both trees to be of same height
