Answer:

n = 5

Step-by-step explanation:

m = (y₂ - y₁) / (x₂ - x₁)

m = (1 - (-8)) / (n - 2)

3 = ( 1 + 8 ) / ( n - 2)

3 = 9 / ( n - 2)

n - 2 = 9 / 3

n - 2 = 3

n = 3 + 2

n = 5

Order the polynomial -x4 y2 + 7x3 y3 -3xy5 + 2x2 y4 in descending powers of x answer
Ilya [14]

Answer:

Step-by-step explanation:

Answer is -x^4 y^2 + 7x^3 y^3 + 2x^2 y^4 -3xy^5

Explanation:

When we are asked to arrange the polynomial in descending order of the powers, also if there is more than one variable, then we need to add all the powers of the variables and then arrange them.

So here in the question, we have to arrange in descending order for the powers of variable x, so we will take the highest order of x first and then arrange in the descending order, as follows:

-x^4 y^2 + 7x^3 y^3 + 2x^2 y^4 -3xy^5

Complete the table to investigate dilations of exponential functions.
Zinaida [17]

Answer:

a = 1

b = 3

c = 1

d = 2

e = 6

f = 8

Step-by-step explanation:

Any integer with power as zero = 1

<h3>For a</h3>

2^x

2^0

= 1

<h3>For b</h3>

3 * 2^x

3 * 2^0

3 * 1

= 3

<h3>For c</h3>

2 ^ 3(x)

2 ^ 3(0)

2 ^ 0

= 1

<h3>For d</h3>

2^1

= 2

<h3>For e</h3>

3 * 2^x

3 * 2^1

3 * 2

= 6

<h3>For f</h3>

2 ^ 3(x)

2 ^ 3(1)

2 ^ 3

2 * 2 * 2

= 8

Zoe has $24 in a savings account. The interest rate is 5% per year and is not compounded. How much will she have to save in 4 ye
umka2103 [35]

Answer:

$28.8

Step-by-step explanation:

First we need to get the interest on the savings for the 4years. Since it is not compounded, we will use the simple interest (SI) formula.

According to the simple interest formula, SI = Principal × Rate × Time/100

Give principal = $24 rate = 5℅ time = 4years

SI = 24×5×4/100

SI = 480/100

SI = $4.8

Zoe interest for four years will be $4.8.

Amount she has saved for 4years = principal + interest = $24+$4.8

= $28.8
