Answer:

No

Step-by-step explanation:

From what I saw on google for what "one to one" means, It's basically meaning that the bottom of that quadratic function is at point (0 , 0) and hits both (-1 , 1) and (1 , 1) on the graph.

Answer:

x = 2y --------(1)

75x + 250y = 800 ---------(2)

Step-by-step explanation:

Let the number of chicken wings be x

And the number of sliders be y

x = 2y --------(1)

75x + 250y = 800 ---------(2)

The system of equation is x = 2y and 75x + 250y = 800.

x = 2y --------(1)

75x + 250y = 800 ---------(2)

Answer:

x=1

Step-by-step explanation:

1/2(8-6x)=x

Distribute

1/2 * 8 - 1/2 * -6x = x

4 -3x = x

Add 3x to each side

4 -3x+3x= x+3x

4 = 4x

Divide each side by 4

4/4 = 4x/4

1= x

Answer:

The answer is D, -11 degrees.  

Step-by-step explanation:

Angle RQP is total sum of angles RQU, (96 + x) and UQP, (x + 57).  

Angle RQP = 131.  

(96 + x) + (x + 57) = 131

153 + 2x = 131

2x = -22

x = -11.  

Therefore, answer is -11 degrees.  

Answer : x= 11°

AngleA=44°

AngleB=55-9=46°

Answer:

                1 C) 23

               2 D) x + y + 2

Step-by-step explanation:

1.

a = 1 ,  b = -23, c = 130

b²-4ac = (-23)²- 4×1×130 = 529 -520 = 9>0

if solutions (A=x₁, B=x₂) exist (b²-4ac≥0) then based on vieta's formula:

[tex]A+B=x_1+x_2=-\dfrac{b}a=-\dfrac{-23}1=23[/tex]

sum of two even integers is na even integer

sum of two odd integers is na even integer

only sum of an even integer and an odd integer is an odd integer

x is even and y is odd so 2x is even and ±2y is even and x+y is odd

1 is odd and 2 is even which means:

2x±2y is even,

x+y + 1 is even

x-2y is even

only x+y+2 is odd (as sum of odd x+y and even 2)

Answer:

There are not 3 but only 2. The answer is below!

ASA stands for "angle, side, angle" and means that we have two triangles where we know two angles and the included side are equal. If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.

area of rectangle = l*b

                         =     (3x-y+4) ( X+7)

                       = 3x²-xy + 4x+21x-7y+28

                       = 3x²-xy +25x-7y +28

Area of square = l²

                        = (x-2)²= x²- 4x +4

area of shaded region=( 3x²-xy +25x-7y +28) -(x²- 4x +4)

Answer:

x^2 + -9 x + 18 = (x - 9) x + 18 = (x - 6) (x - 3) all three are alternanate forms.

Step-by-step explanation:

Expand the following:

(x - 6) (x - 3)

Hint: | Multiply x - 6 and x - 3 together using FOIL.

(x - 6) (x - 3) = (x) (x) + (x) (-3) + (-6) (x) + (-6) (-3):

x x - 3 x - 6 x - 6 (-3)

Hint: | Combine products of like terms.

x x = x^2:

x^2 - 3 x - 6 x - 6 (-3)

Hint: | Multiply -6 and -3 together.

-6 (-3) = 18:

x^2 - 3 x - 6 x + 18

Hint: | Group like terms in x^2 - 3 x - 6 x + 18.

Grouping like terms, x^2 - 3 x - 6 x + 18 = x^2 + (-3 x - 6 x) + 18:

x^2 + (-3 x - 6 x) + 18

Hint: | Combine like terms in -3 x - 6 x.

-3 x - 6 x = -9 x:

Answer:  x^2 + -9 x + 18 = (x - 9) x + 18 =(x - 6) (x - 3)

Answer:

Step-by-step explanation:

H = 2x+6          - the hight

3H = 3(2x+6)      - triple the hight

3H-5 = 3(2x+6) - 5    -  five less than triple the height

Area of triangle:  A = 0.5BH

B = 3(2x+6)-5 = 6x + 18 - 5 = 6x + 13

H = 2x+6

So:

    A = 0.5(2x+6)(6x+13) = (x+6)(6x+13) = 6x² + 13x + 36x + 78

    A = 6x² + 49x + 78

Answer:

1,700 MG

Step-by-step explanation:

1, 360 / 2 = 40% of the daily amount since 20% is taken from the beans.

1360 / 2 = 680

680 (40%) / 2 = 340, which is 20%.

Then, add 20% (340) to 1, 360, which gives the full percentage.
