Consider the following expression and determine which statements are true. m+(5n)(9-p)-6-r^2

Fed [463]

Answer:

(B)The expression (5n)(9-p) is the product

(D)The expression 9-p has exactly two terms

Step-by-step explanation:

In the expression;

$m+(5n)(9-p)-6-r^2$

The coefficient of m is 1, therefore Option A is not true

The product of 5n and 9-p is (5n)(9-p), therefore Option B is true.

The expression 9-p has exactly two terms,9 and p.

Therefore, Options B and D are true.

3x - 4y = 8

3x + 3y = 15

3x - 4y = 8 -

7y = 7

y = 1

x + y = 5

x + 1 = 5

x = 4

x = 4

y = 1

What is the answer to 8(x-3)+7=2x(4-17)

nadezda [96]

Answer:

x=1/2

Step-by-step explanation:

First you distribute the 8 over the (x-3) giving you 8x-24. Do the same for 2x and (4-17). That should give you 8x-34x.

Your equation should look like : 8x-24+7=8x-34x

Next try to balance out your equation. You want your x's all by themselves in order to solve.

The 8x's cancel eachother out so you have -24+7= -34x.

Add the like terms of -24 and 7 to get -17.

Equation: -17= -34x

Divide both sides by -34 to get x by itself.

-17/-34 = x

Reduce by dividing the numerator and denominator by 17 to get -1/-2

Since they are both negative the fraction turns positive.

So the answer should be x=1/2

Just Peachy Orchard produced 1100 bushels of peaches last year. This year the owner earned $8800 from sales. He's thinking that

Slav-nsk [51]

Answer:

$P(t) ={8*(1.01)^t}$

Step-by-step explanation:

The number of bushels produced is given by:

$B(t)= 1100(1.1)^t$

The owner's income is given by:

$S(t) = 8800(1.111)^t$

Income is given by the price per unit multiplied by the number of units sold. Therefore, the price function can be represented as:

$P(t) =\frac{S(t)}{B(t)} \\P(t) =\frac{8800(1.111)^t}{1100(1.1)^t} \\P(t) =\frac{8*1100(1.1)^t*(1.01)^t}{1100(1.1)^t}\\P(t) ={8*(1.01)^t}$
