the figure is symmetric about the x- and y-axis. what is the area of the figure below

Step-by-step explanation:

20x-25+3x-1=20

20x+3x=20+25+1

23x=46

X=2

Answer:

x=2

Step-by-step explanation:

5(4x-5)+3x-1=20 (given)

20x - 25 + 3x -1 = 20 (distribute)

23x -26 = 20 (combine like terms)

23x = 46 (add)

x=2 (division)

Answer:

[tex]a=\sqrt{6},\:a=-\sqrt{6}[/tex]

Step-by-step explanation:

Given

as

[tex]\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}[/tex]

so

[tex]a^2=6[/tex]

[tex]a=\sqrt{b},\:a=-\sqrt{b}[/tex]

Therefore,

[tex]a=\sqrt{6},\:a=-\sqrt{6}[/tex]

Answer:

The solutions to the system of the equations are:

[tex]y=1,\:x=3[/tex]

Step-by-step explanation:

Given the equations

[tex]y=\frac{2}{3}x-1;\:y=-x+4[/tex]

solving the system of equation

[tex]\begin{bmatrix}y=\frac{2}{3}x-1\\ y=-x+4\end{bmatrix}[/tex]

Arrange equation variables for elimination

[tex]\begin{bmatrix}y-\frac{2}{3}x=-1\\ y+x=4\end{bmatrix}[/tex]

[tex]y+x=4[/tex]

[tex]-[/tex]

[tex]\underline{y-\frac{2}{3}x=-1}[/tex]

[tex]\frac{5}{3}x=5[/tex]

[tex]\begin{bmatrix}y-\frac{2}{3}x=-1\\ \frac{5}{3}x=5\end{bmatrix}[/tex]

solving for x

[tex]\frac{5}{3}x=5[/tex]

[tex]5x=15[/tex]

Divide both sides by 15

[tex]\frac{5x}{5}=\frac{15}{5}[/tex]

[tex]x=3[/tex]

[tex]\mathrm{For\:}y-\frac{2}{3}x=-1\mathrm{\:plug\:in\:}x=3[/tex]

[tex]y-\frac{2}{3}\cdot \:3=-1[/tex]

[tex]y-2=-1[/tex]

Add 2 to both sides

[tex]y-2+2=-1+2[/tex]

[tex]y=1[/tex]

Therefore, the solutions to the system of the equations are:

[tex]y=1,\:x=3[/tex]

Answer:

d. 0.2 ( x + 4 )

Step-by-step explanation:

0.2x + 0.8

Both 0.2x and 0.8 have a common factor of 0.2, hence pull 0.2 out.

0.2x + 0.8

0.2 ( x + 4 )

Answer:

The mass of 3.13*10²³ molecules of carbon dioxide is 22.88 g.

Step-by-step explanation:

Avogadro's Number or Avogadro's Constant is the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole and it applies to any substance.

Then you can apply the following rule of three: if 6.023*10²³ molecules are present in 1 mole, 3.13*10²³ molecules are present in how many moles?

[tex]moles=\frac{3.13*10^{23}molecules*1 mole }{6.023*10^{23}molecules}[/tex]

moles= 0.52

Since the molar mass of carbon dioxide is 44 g / mole, then the following rule of three can be applied: if there are 44 g in 1 mole, how much mass is there in 0.52 moles?

[tex]mass=\frac{0.52 moles*44 g}{1 mole}[/tex]

mass= 22.88 g

The mass of 3.13*10²³ molecules of carbon dioxide is 22.88 g.

Answer:

-765/25

Step-by-step explanation:

Given :

A pre-image arrow pointing east is rotated 135° clockwise.

To Find :

In which direction is the image arrow point.

Solution :

90° clockwise shift make it south.

Now, remaining angle for rotation ( 135 - 90 )° = 45°.

So, direction of moving 45° more clockwise makes it 45° west of south or 45° south of west.

Hence, this is the required solution.

Answer:

108.88

Step-by-step explanation:

Given that:

Equation of Regression line obtained for couple's IQ:

y=9.88+0.9x

x represents the IQ score of the husband

The best predicted IQ of wife Given that husband's IQ is 110

y = 9.88 + 0.9(110)

y = 9.88 + 99

y = 108.88

Answer:

a = 1, b = - 3

Step-by-step explanation:

Expand the factors on the left side, then compare the coefficients of like terms on both sides.

left side

(ax + 4)(2x + b) ← expand using FOIL

= 2ax² + abx +8x + 4b

= 2ax² + x(ab + 8) + 4b

Compare coefficients of like terms with those on right side.

coefficients of x² terms

2a = 2 ( divide both sides by 2 )

a = 1

comparing constant terms

4b = - 12 ( divide both sides by 4 )

b = - 3

Answer:

x is less than oe equal to 12

Answer:

x ≤ 15

Step-by-step explanation:

7x - 6 ≤ 3x + 54

Subtract 3x from both sides;

4x - 6 ≤ 54

Add 6 to both sides;

4x ≤ 60

Divide both sides by 4;

x ≤ 15

Step-by-step explanation:

y=2/3 orange for each friend (decimal: 0.6667 rounded to 4d. p)

PREMISES

y=the fraction of 2 oranges that each of 3 friends shares equally

CALCULATIONS

To distribute 2 oranges equally between 3 friends requires that the oranges be sliced proportionately equal to the number of friends which is 3

So, then,

y=

Each friend receives 1/3 of each of 2 oranges making 2/3 orange for each friend.

If y=2/3 orange, then the equations

3*2/3 orange=2 oranges

6/3 oranges=2 oranges and

2 oranges=2 oranges prove the solution y=2/3 orange to the fraction of 2 oranges shared by each of 3 friends
