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.
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
Answer:
225 milliliters
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

a² + b² = c²
if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root:
a = √(c² - b²)
if leg b is unknown, then
b = √(c² - a²)
for hypotenuse c missing, the formula is
c = √(a² + b²)

The product of two numbers is 713. The first number is 9 more than the second number. Which equation can be used to find x, the greater number?
x(x − 9) = 713
x(x + 9) = 713
x2 − 9 = 713
x2 + 9 = 713
Answer:
x(x+9)=713 because x multiplied by x is x or its like multiplying 1x1=1
Answer:Let x = first number and y = second number

evaluate tan-1 (1.6) giving your answer to the nearest degree
Answer:
58degrees
Step-by-step explanation:
Given
tan^-1(1.6)
= tan^-1(16/10)
= tan^-1(8/5)
= 57.99 degrees
Hence the value of tan^-1(1.6) to the nearest degrees is 58degrees

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
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

30 points !!!
Answer: A.)$11
Step-by-step explanation: I did the test
From the graph of the regression model given, the estimated hourly rate for an individual with 5 years experience would be $11.
The graph models the relationship between hourly rate and years of experience. The point of intersection of the y and x axis on the regression line gives the pair of points.Hence, the value of y, when x = 5 on the regression line is $11.

Mia took 20 seconds to run 100m. Find the ratio of distance traveled to the time Emma took to run 100m.
Answer:
The ratio should be 100 : 20. If it needs to be simplified then 5:1
Step-by-step explanation:
100 m is the distance traveled and the time it took was 20 seconds. Divide both sides by 20 and you get 5:1
(If it doesn't need to be simplified then 100 : 20)
