A) 3x+5y=3(3)+5(2)

=9+10

=19

B) x²+y²=3²+2²

=9+4

=13

C) -5x+9=-5(3)+9

=-15+9

=-6

D) xy-1=(2×3)-1

=6-1

=5

E) 2x²-y=2(3)²-2

=18-2

=16

F) 2y-x+5+x²-3y=2(2)-3+5+3²-3(2)

=4-3+5+9-6

=9

Hi

Just told you :  first know by heart remarkable identities !  

Then apply :  

4x²-12x = -9

4x²-12x +9 =0

(2x-3)² = 0

(2x-3) (2x-3)  = 0

Now you have a double solution :

2x-3 = 0

and 2x -3 = 0

I let you try !

Answer:

6x - 1 = 9

Step-by-step explanation:

1. first you have to divide every term in the equation by 2

   12x/2 + 4/2 = 20/2

2. simplify

   6x + 2 = 10

3. next you have to subtract one from both sides

   6x + (2-1) = (10-2)

4. simplify

    6x + 1 = 9

Answer:

points doesn't lie in the given line.

Step-by-step explanation:

firmula for finding the equation of these points are

[tex] \frac{y - y1}{y2 - y1} = \frac{x - x1}{x2 - x1} [/tex]

x1=2 , x2=-3, y1= 9 ,y2=-6

subtitute all values in formula

[tex] \frac{y - 9}{ - 6 - 9} = \frac{x - 2}{ - 3 - 2} [/tex]

[tex]y - 3x - 3 = 0[/tex]

if we put (2,9) and (-3,-6) in new equation then they will satisfy equation.so this is the equation where points lie in the line

Answer:

- 20x² + 26x + 8

Step-by-step explanation:

Given

4(2x³ - 5x² + 8x + 2) - 6x - 8x³ ← distribute parenthesis by 4

= 8x³ - 20x² + 32x + 8 - 6x - 8x³ ← collect like terms

= - 20x² + 26x + 8

Answer:

[ - 4, 8 ]

Step-by-step explanation:

parenthesis ( ) is used when end values are not equal to x

brackets [ ] are used when the end values are equal to x

For - 4 ≤ x ≤ 8

Then x can equal both - 4 and 8 , so

[ - 4, 8 ] ← is the appropriate interval notation

Answer:

11/16 pounds

Step-by-step explanation:

The difference between their weights can be found by subtracting 6 1/4 pounds from 5 9/16 pounds to find the difference. To do this we must transfer it from 1/4 to sixteenths which is 4 sixteenths. Then we subtract.

 6 4/16

(- 2, 3 ]

Step-by-step explanation:

parenthesis ( ) is used when the end value is not equal

brackets [ ] are used when the end value is equal

Here numbers are greater but not equal to - 2 and less than or equal to 3

(- 2, 3 ] ← is the appropriate interval notation

Answer:

D

Step-by-step explanation:

Start with the 9. It goes to your right. It is on the plus x axis.

You are either in quad 1 or quad 4

We need the - 10 to decide which.

+ 10 would go up and that would mean quad 1

- 10 mean going down so you are in Quad 4
