All you need to do p(x)-q(x).  So:

(x^{2}-1)-(5)(x-1)

That's it!

Solve x-5y=-30, 3x+5y=10 show your work
marin [14]

1) x = 5y - 30  

2) x = - 1.6y + 3.3

<em>im assuming these are 2 different questions</em>

<h3>Explanation:</h3><h3>1)</h3>

Start with the equation:

x - 5y= -30

add 5y to both sides:

x = 5y - 30

Your answer is x = 5y - 30  

<h3>2)</h3>

Start with the equation:

3x+5y=10

subtract 5y from both sides:

3x = -5y + 10

divide by 3 to get x singular

x = - 1.6y + 3.3

Your answer is x = - 1.6y + 3.3

Hope this helps :)

Five whole numbers are written in order
jeka57 [31]

Answer:

x=7

y=8

Step-by-step explanation:

-Given that the mean and median is the same.

-Let b=mean =median

#Given that the set is arranged in order and is even:

median=\frac{n+1}{2}\\\\Median=3^{rd} \ term\\\\=x

Hence:

b=median=mean\\\\b=x\\\\\therefore mean=median=x

-Applying the mean formula:

\bar x=\frac{1}{n}\sum{x_i}\\\\\therefore 5x=4+6+x+y+10\\\\4x=20+y\\\\x=5+0.25y

#Since the number are in order:

6

Hence, x=7 and y=8

Kayla’s dollhouse has 15.15 square feet downstairs and 6.45 square feet upstairs. What is the estimated total area if you round
Hitman42 [59]

  • The area of Kayla's dollhouse upstairs = 15.15 square feet

  • The area of Kayla's dollhouse downstairs = 6.45 square feet

  • To find the estimated Total area of Kayla's dollhouse, we would apply the Addition Operation

  • The estimated total area is calculated using the formula :

Area of the dollhouse upstairs + Area of the dollhouse downstairs

Rounding to the decimals to the nearest tenth

  • The area of Kayla's dollhouse upstairs to the nearest tenth = 15.2 square feet

  • The area of Kayla's dollhouse downstairs to the nearest tenth = 6.5 square feet

15.2 square feet + 6.5 square feet = 21.7 square feet

The estimated total area of Kayla's dollhouse is  21.7 square feet

Given the trinomial x^2+bx+c where both the first and second signs are positive, the signs of the factors will be: A. both negat
Lunna [17]
The answer here is C. The sign of the factors are both positive. We can use the FOIL method as reference in determining the sign of the factors. The 3rd term C is positive; therefore our only option is either both negative or both positive. Looking the middle term, which is positive, we know that the middle term is the sum of the outer and inner in FOIL method, which means, signs of the factors must be both positive
