how many solutions is there to the system of equations? 2x + 3y = 11 -4x - 6y = -22

9514 1404 393

Answer:

  B

Step-by-step explanation:

The line has a y-intercept of 40 (in agreement with all answer choices). It goes through the point (6, 30), so has a "rise" of -10 for a "run" of 6. The slope is ...

  m = rise/run = -10/6 = -5/3

The equation with a slope of -5/3 is the one shown in choice B.

Answer:

B

Step-by-step explanation:

Answer:

x=70°

Step-by-step explanation:

Three triangles can be made out of that shape so total int. angles = 3 x 180°=540°.

so 40 + 110 + 4x + 40 + x = 540°

190+5x=540°

5x=350°

x=350/5=70°

Answer:

[tex]m=\frac{3}{4}[/tex]

Step-by-step explanation:

[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(15,\:7\right),\:\left(x_2,\:y_2\right)=\left(3,\:-2\right)[/tex]

[tex]m=\frac{-2-7}{3-15}[/tex]

[tex]\mathrm{Refine}[/tex]

[tex]m=\frac{3}{4}[/tex]

Answer:

Step-by-step explanation:

Use the Law of Cosines:

c^2 = a^2 + b^2 - 2ab*cos C becomes

7^2 = 11^2 + 13^2 - 2(11)(13)cos C.

Once you have cos C, and then side c, you can use the Law of Sines to find the other two interior angles.

Answer:

A rectangle has 4 sides with C: Two Lines of Symmetry.

Step-by-step explanation:

Answer:

B. 12x + 8

Step-by-step explanation:

2x + 5 + 4x - 1 + 2x + 5 + 4x - 1

Combine like terms.

6x + 5 - 1 + 2x + 5 + 4x + 1

8x + 5 - 1 + 5 + 4x - 1

12x + 5 - 1 + 5 - 1

12x + 10 - 1 - 1

12x + 10 - 2

Subtract 2 from 10 to get 8.

12x + 8

The perimeter of the rectangle is 12x + 8, which is B.

Answer:

78

Step-by-step explanation:

x = your age

400 - 2x = 244

subtract 400 from both sides of the equation:

-2x = -156

divide both sides by -2:

x = 78

Answer: 78

Step-by-step explanation:

x = your age

400 - 2x = 244

subtract 400 from both sides of the equation:

-2x = -156

divide both sides by -2:

x = 78

Answer:

g(x) has the greater rate of growth

Step-by-step explanation:

Answer:

76degrees

Step-by-step explanation:

Using the theorem which states that the vertex of the angle inside a circle is half the sum of the measured intercepted arcs. Hence;

Angle at the vertex = 53 degrees

Half the sum of intercepted arcs = 1/2(3x+3+10x-14)

Half the sum of intercepted arcs = 1/2(13x-11)

Equating to  the vertex to find x

1/2(13x-11) = 53

13x - 11 = 2 * 53

13x - 11 = 106

13x = 106 + 11

13x = 117

x = 117/13

x = 9

For the arc 3x + 3

= 3(9) + 3

= 27 + 3

= 30degrees

For the arc 10x - 14

= 10(9) - 14

= 90 - 14

= 76degrees

Hence the measure of the larger of the two arcs is 76degrees

Answer:

[tex]X=49ft[/tex]

Step-by-step explanation:

From the question we are told that:

Height of Eagle [tex]h=40ft[/tex]

Angle of depression [tex]\theta=35\textdegree[/tex]

Generally the trigonometry equation for diagonal X is mathematically given by

[tex]Cos\theta \textdegree=\frac{Adjacent}{Hypotenuse} }[/tex]

[tex]Cos\theta \textdegree=\frac{h}{X} }[/tex]

[tex]X=\frac{40}{Cos 35 } }[/tex]

[tex]X=48.83ft[/tex]

[tex]X=49ft[/tex]

Answer:

b. 22

Step-by-step explanation:

7 x 3.14 = 21.95

( you have to buy 22 because you connot buy half of one so

you have to round up)

21.95 - 22

Answer:

A. no solution

Step-by-step explanation:

y = 3x + 9

y = 3x - 4

Let's solve this.

We can see that both equations equal y, so we can set them equal to each other.

3x + 9 = 3x - 4

Combine like terms.

[add 4 to both sides]

3x + 13 = 3x

[subtract 3x from both sides]

13 = 0

This statement is not true; therefore, there is no solution.

If we look at the graph below, we can see the lines are parallel. Parallel lines will never intersect and have no solution in a system of equations.

Answer:

128.6

Step-by-step explanation:

I just did the math

Answer:

107°

Step-by-step explanation:

m∠m+m∠p= 180°

(7x+31)°(21x-19)°=180°

7x+31+21x-19= 180

7x+21x=180+19-31

28x=168

x= 168/28

x= 6

m∠p= (21x-19)°

= (21(16)-19)°=(126-19)°

= 107°
