Solve The System Of Equations 9x-9y=-9 And 4x-3y=-8 By Combining The Equations PLEASE HELP QUICKLY!!!!!

Answers

Answer 1

9x-9y=-9

x-y=-9/9

x-y+1=0.......(1)

4x-3y=-8

4x-3y+8=0....(2)

combining equation we get

(x-y+1)(4x-3y+8)=0

x(4x-3y+8)-y(4x-3y+8)+4x-3y+8=0

4x²-3xy+8x-4xy+3y²-8y+4x-3y+8=0

4x²+3y²-7xy+12x-11y+8=0 is your equation.

Step-by-step explanation:

Marianne tried to drink a slushy as fast as she could. She drank the slushy at a rate of 4.5 milliliters per second. After 17 seconds 148 5 milliliters of slushy remains. how much slushy was originally in the cup?

let x = slushy originally in the cup

total slushy consumed in 17 seconds = 17 x 4.5 = 76.5 ml

x - 76.5 = 148.5

collect like terms

x = 148.5 + 76.5

x = 225 ml

Step-by-step explanation:

The triangle shown is a right triangle. I am assuming that the 'x' is the missing angle measurement.

The three angle measures in a triangle add up to 180 degrees.

[tex]60 + 90 = 150\\\\180 - 150 = 30[/tex]

The third angle should measure 30 degrees.

Hope this helps.

Answer:

30 degree

Step-by-step explanation:

60+90+x = 180 ( Angle sum property of a triangle )

150+x =180

x = 180-150

x = 30

therefore x is 30 degree

Which expression is equivalent to 2(x2 – 1) + 3x(x – 4)?
(1) 5x2 – 5
(3) 5x2 – 12x – 1
(2) 5x2 - 6
(4) 5x2 – 12x – 2

Answers

The equivalent expression of 2(x² – 1) + 3x(x – 4) is 5x² - 12x - 2

How to find equivalent expression?

The equivalent expression of the expression can be found as follows;

2(x² – 1) + 3x(x – 4)

open the brackets

2x² - 2 + 3x² - 12x

Therefore, let's combine like terms

2x² + 3x² - 12x - 2

Let's do the arithmetic for like terms

2x² + 3x² - 12x - 2

5x² - 12x - 2

Therefore, the equivalent expression of  2(x² – 1) + 3x(x – 4) is 5x² - 12x - 2
